Installing the 6400-S  
Physical Installation1  
Anchor the equipment rack that will contain the 6400.  
The equipment rack must be anchored to an unmovable support to prevent it  
from falling over when one or more systems are extended in front of the rack  
on slides. You must also consider the weight of any other device installed in  
the rack. A crush hazard exists should the rack tilt forward which could cause  
serious injury.  
If AC power supplies are installed  
Mains AC power disconnect  
The AC power cord(s) is considered the mains disconnect for the 6400-S and  
must be readily accessible when installed. If the individual server power  
cord(s) will not be readily accessible for disconnection then you are  
responsible for installing an AC power disconnect for the entire rack unit. This  
main disconnect must be readily accessible, and it must be labeled as  
controlling power to the entire rack, not just to the 6400-S(s). To remove all  
power, two AC cords must be removed.  
Grounding the rack installation  
To avoid the potential for an electrical shock hazard, you must include a third  
wire safety ground conductor with the rack installation. If the 6400-S power  
cord is plugged into an AC outlet that is part of the rack, then you must  
provide proper grounding for the rack itself. If the 6400-S power cord is  
plugged into a wall AC outlet, the safety ground conductor in the power cord  
provides proper grounding only for the 6400-S. You must provide additional,  
proper grounding for the rack and other devices installed in it.

User Guide V2IU 6400-S Converged Network Appliance  
Overcurrent protection  
The 6400-S is designed for an AC line voltage source with up to 20 amperes of  
overcurrent protection per cord feed. If the power system for the equipment  
rack is installed on a branch circuit with more than 20 amperes of protection,  
you must provide supplemental protection for the 6400-S. The overall current  
rating of a 6400-S configured with two power supplies is less than 4 amperes.  
If DC power supplies are installed:  
Connection with a DC source should only be performed by trained service  
personnel. The 6400-S with DC input is to be installed in a Restricted Access  
Location in accordance with articles 110-16, 110-17, and 110-18 of the National  
Electric Code, ANSI/NFPA 70. The DC source must be electrically isolated by  
double or reinforced insulation from any hazardous AC source. The DC  
source must be capable of providing up to 650 Watts of continuous power per  
feed pair.  
Main DC power disconnect:  
You are responsible for installing a properly rated DC power disconnect for  
the 6400-S system. This mains disconnect must be readily accessible, and it  
must be labeled as controlling power to the 6400-S. The circuit breaker of a  
centralized DC power system may be used as a disconnect device when easily  
accessible and should be rated no more than 10 amps.  
Grounding the 6400-S  
To avoid the potential for an electrical shock hazard, you must reliably connect  
an earth grounding conductor to the 6400-S. The earth grounding conductor  
must be a minimum 14AWG connected to the earth ground stud(s) on the rear  
of the 6400-S. The safety ground conductor should be connected to the chassis  
stud with a Listed closed two-hole crimp terminal with a maximum width of  
0.25 inch. The nuts on the chassis earth ground studs should be installed with  
a 10 in/lbs torque. The safety ground conductor provides proper grounding  
only for the 6400-S. You must provide additional, proper grounding for the  
rack and other devices installed in it.  
Overcurrent protection  
Overcurrent protection circuit breakers must be provided as part of each host  
equipment rack and must be incorporated in the field wiring between the DC  
source and the 6400-S. The branch circuit protection shall be rated minimum  
75Vdc, 10 A maximum per feed pair. If the DC power system for the  
equipment rack is installed with more than 10 amperes of protection, you must  
provide supplemental protection for the 6400-S. The overall current rating of  
a 6400-S configured with two power supplies is 8 amperes.  
Do not attempt to modify or use an AC power cordset that is not the exact type  
required. You must use a power cordset that meets the following criteria:

Installing the 6400-S  
•
•
Rating: For U.S./Canada cords must be UL Listed/CSA Certified type  
SJT, 18-3 AWG. For outside U.S./Canada cords must be flexible  
harmonized (<HAR>) or VDE certified cord with 3 x 0.75 mm conductors  
rated 250 VAC.  
Connector, wall outlet end: Cords must be terminated in grounding-type  
male plug designed for use in your region. The connector must have  
certification marks showing certification by an agency acceptable in your  
region and for U.S. must be Listed and rated 125% of overall current  
rating of the 6400-S.  
•
•
Connector, 6400-S end: The connectors that plug into the AC receptacle  
on the 6400-S must be an approved IEC 320, sheet C19, type female  
connector.  
Cord length and flexibility: Cords must be less than 4.5 meters (14.76 feet)  
long. CAUTION Temperature: The temperature in which the 6400-S  
operates when installed in an equipment rack, must not go below 5 °C (41  
°F) or rise above 40 °C (104 °F). Extreme fluctuations in temperature can  
cause a variety of problems in your 6400-S.  
•
Ventilation: The equipment rack must provide sufficient airflow to the  
front of the 6400-S to maintain proper cooling. The rack must also include  
ventilation sufficient to exhaust a maximum of 1023 BTU's per hour for the  
6400-S. The rack selected and the ventilation provided must be suitable to  
the environment in which the 6400-S will be used.  
Power Supplies1  
The power supply cage shown is accessed from the rear of the chassis. The  
power supply cage supports up to two hot-swap power supplies (either AC  
input or DC input) in a (1+1) redundant configuration. Only the DC input  
version is NEBS certified. The combined output power to the 6400-S system is  
470 Watts per DC supply and 500 Watts per AC supply.  
DC Power Supply Interface Requirements  
The DC power source may produce hazardous voltage levels exceeding -60  
VDC and high energy levels above 240VA that may cause electric shock or  
burns. All DC input connections should be made only by a qualified service  
person to prevent injury. All wiring terminals connected to the DC input  
terminal block must be fully insulated with no exposed bare metal.  
The power supply will operate within all specified limits over the input  
voltage range outlined as follows:

Link Status  
Link Status displays the status of the Ethernet connections. Ethernet auto  
negotiation is often unreliable, especially between different vendors or old and  
new networking equipment. Failure of auto negotiation is generally not a  
cause for concern. However, if the negotiated rates change intermittently, or  
the link is down or there is no link, the link rate may need to be set manually  
on the Set Link Rate page. Intermittent data and voice outages may be caused  
by auto negotiation "flutter". Setting the link rate manually is recommended  
and ensures that the device at the far end of the connection will not renegotiate  
rates during VoIP operation.  
Interface Information  
The specific status and configuration information for the system interfaces is  
displayed in the Interface Information section. The MAC address of interface  
eth0 is needed to retrieve the VoIP ALG License Key if the license information  
is lost.  
The interface statistics can point to areas of congestion in the network. If the  
errors statistic increase during normal operation of the device, it may be an  
indication of excessive congestion on the network interface. If the congestion  
is not corrected, the quality of voice calls will be affected. The topology of the  
network attached to the network interface with the errors should be examined  
and modified to better segment and isolate network traffic. See Link Status on  
page 3-6.

User Guide V2IU 6400-S Converged Network Appliance  
The vast majority of Ethernet networking devices including the 6400-S use  
Note  
"autonegotiate" as a default setting. Chances are that you will not have to set the  
Ethernet link rate. Please use caution if manually configuring the link rate, as a  
speed or duplex mismatch will result in a loss of connectivity.  
If needed, configure the rate of the physical Ethernet port on the 6400-S. The  
default setting for the Ethernet port is autonegotiate, and it applies to both the  
link speed and duplex with locally attached devices.  
The link rate of an interface can be assigned to a desired rate. A network  
administrator may want to set the rate manually if autonegotiation fails to  
select a rate consistently or if it selects a rate that is slower than the maximum  
rate supported by both interfaces.  
To set the link rate:  
1. In the navigation bar, select System.  
2. In the System menu, select Set Link.  
3. Select Subscriber Ethernet or Provider Ethernet.

Configuring VoIP  
An application-layer gateway provides basic proxy features for voice and  
video over IP traffic. Serving as an ALG proxy, the 6400-S provides Network  
Address Translation (NAT) services for the protected softswitch, gatekeeper  
or other media devices. It maps multiple devices on the subscriber interface  
(public) to a single IP address on the provider interface (private). The ALG  
must first recognize and register a public network based device before it  
presents traffic from the IP telephone, video endpoint or data device through  
its provider port.  
The 6400-S contains an MGCP, SIP, and H.323 call-control proxy ALG. VoIP  
phones, video endponts and client adapters have to be configured to point to  
the 6400-S as the call-control server, proxy, gatekeeper or gateway (depending  
on protocol). The 6400-S then forward this traffic onto the actual call-control  
server or gatekeeper.  
For corporate customers with high-end routers and firewalls, the 6400-S can be  
configured as a VoIP Application Layer Gateway only. This allows all of the  
normal data traffic to continue to be handled by the existing network devices,  
and only voice or traffic to be handled by the 6400-S. For this configuration, the  
6400-S Subscriber Ethernet port is connected to the internet. The 6400-S  
Provider Ethernet port is connected to a port on the local Ethernet switch.

have their RTP traffic flow to and back  
from the EP's subscriber interface.  
SIP Expires override  
The SIP Expires override field specifies  
the number of seconds a registration  
should be valid. The 6400-S uses this  
value to re-write the expires value  
returned from the soft-switch before  
forwarding it to the IP phone. This value is  
used to force the IP phone to register at  
the configured interval And helps to  
maintain NAT bindings in network based  
firewalls when the 6400-S is performing  
NAT/firewall traversal.  
SIP Soft-Switch Expires override  
The SIP Soft-Switch expires override field  
specifies the number of seconds that  
should be used when forwarding  
registration messages to the soft-switch  
on behalf of the IP phones. This should be  
higher than the rate pacing value,  
otherwise, the soft-switch may consider  
the phone's registration to have expired. If  
this field is not set, the phone's value is  
forwarded unchanged.

In order to prevent this, you can set the  
SIP Register pacing field to the number of  
seconds to wait before forwarding a  
register message from one phone to the  
soft-switch. Any register messages  
received before this time will be locally  
answered by the 6400-S. For example,  
you may set the expires value to 60 and

Configuring VoIP subnet routing  
In its simplest configuration, the 6400-S acts as a proxy for a soft-switch or  
H.323 gatekeeper on its immediate Provider subnet. Because these devices  
reside on the same subnet as the 6400-S, packets proxied by the ALG function  
do not require additional routing information.  
The 6400-S can support a VoIP call-control server or H.323 gatekeeper on it's  
Provider side but not located immediately on the Provider-side subnet by  
configuring VoIP Subnet Routes.  
Using the VoIP Subnet Routing feature, the 6400-S can be configured to serve  
these remote devices. Three pieces of information are required for each subnet  
containing the VoIP call-control server or H.323 gatekeeper:  
•
•
•
The IP Network address.  
The Netmask.  
The Gateway.  
You can configure up to 20 VoIP subnets.

Configuring VoIP survivability  
Survivability features enable the 6400-S to extend the availability of VoIP  
services. These features include:  
•
•
Support for redundant SIP softswitches  
Support for the Virtual Router Redundancy Protocol (VRRP), allowing a  
backup 6400-S to take control for a master 6400-S in the event of a failure.  
Configuring sofswitch survivability  
If you will be using multiple SIP softswitches then you will need to enable  
server redundancy and specify the time between DNS lookups in the 6400-S.  
Enabling redundancy allows a DNS server to provide a list of multiple call  
processing servers to the 6400-S in the answers to SRV lookups. Each server in  
the list will be monitored using periodic messages by the 6400-S and the  
highest priority server that is currently reachable will be used for signaling.  
The 6400-S uses the reachability settings described below to determine the  
status of remote servers and remove inoperable servers from the list.  
Triggers can also be used by the 6400-S appliance to determine when to  
forward call requests to a secondary server in the list. A trigger is set when a  
configured number of resends are received by the 6400-S from a SIP user agent  
attempting to place a call. When initiating a call a SIP user agent will send an  
INVITE message to the 6400-S that will then be forwarded to the primary

Software included in this product contains a module called PsyVoIP which is  
protected by copyright and by European, US and other patents and is  
provided under licence from Psytechnics Limited.  
Portions of this product also include software sponsored by the Free Software  
Foundation and are covered by the GNU GENERAL PUBLIC LICENSE:  
GNU GENERAL PUBLIC LICENSE  
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND  
MODIFICATION  
This License applies to any program or other work which contains a notice  
placed by the copyright holder saying it may be distributed under the terms of  
this General Public License. The "Program", below, refers to any such program  
or work, and a "work based on the Program" means either the Program or any  
derivative work under copyright law: that is to say, a work containing the  
Program or a portion of it, either verbatim or with modifications and/or  
translated into another language. (Hereinafter, translation is included without  
limitation in the term "modification".) Each licensee is addressed as "you".  
Activities other than copying, distribution and modification are not covered  
by this License; they are outside its scope. The act of running the Program is  
not restricted, and the output from the Program is covered only if its contents  
constitute a work based on the Program (independent of having been made by  
running the Program).  
Whether that is true depends on what the Program does.  
1.  
You may copy and distribute verbatim copies of the Program's source  
code as you receive it, in any medium, provided that you conspicuously and  
appropriately publish on each copy an appropriate copyright notice and  
disclaimer of warranty; keep intact all the notices that refer to this License and  
to the absence of any warranty; and give any other recipients of the Program a  
copy of this License along with the Program.  
You may charge a fee for the physical act of transferring a copy, and you may  
at your option offer warranty protection in exchange for a fee.

User Guide V2IU 6400-S Converged Network Appliance  
2.  
You may modify your copy or copies of the Program or any portion of it,  
thus forming a work based on the Program, and copy and distribute such  
modifications or work under the terms of Section 1 above, provided that you  
also meet all of these conditions:  
a) You must cause the modified files to carry prominent notices stating that  
you changed the files and the date of any change.  
b) You must cause any work that you distribute or publish, that in whole  
or in part contains or is derived from the Program or any part thereof, to  
be licensed as a whole at no charge to all third parties under the terms of  
this License.  
c) If the modified program normally reads commands interactively when  
run, you must cause it, when started running for such interactive use in  
the most ordinary way, to print or display an announcement including  
an appropriate copyright notice and a notice that there is no warranty  
(or else, saying that you provide a warranty) and that users may  
redistribute the program under these conditions, and telling the user  
how to view a copy of this License. (Exception: if the Program itself is  
interactive but does not normally print such an announcement, your  
work based on the Program is not required to print an announcement.)  
These requirements apply to the modified work as a whole. If identifiable  
sections of that work are not derived from the Program, and can be reasonably  
considered independent and separate works in themselves, then this License,  
and its terms, do not apply to those sections when you distribute them as  
separate works. But when you distribute the same sections as part of a whole  
which is a work based on the Program, the distribution of the whole must be  
on the terms of this License, whose permissions for other licensees extend to  
the entire whole, and thus to each and every part regardless of who wrote it.  
Thus, it is not the intent of this section to claim rights or contest your rights to  
work written entirely by you; rather, the intent is to exercise the right to control  
the distribution of derivative or collective works based on the Program.  
In addition, mere aggregation of another work not based on the Program with  
the Program (or with a work based on the Program) on a volume of a storage  
or distribution medium does not bring the other work under the scope of this  
License.  
3. You may copy and distribute the Program (or a work based on it, under  
Section 2) in object code or executable form under the terms of Sections 1 and  
2 above provided that you also do one of the following:  
a) Accompany it with the complete corresponding machine-readable  
source code, which must be distributed under the terms of Sections 1  
and 2 above on a medium customarily used for software interchange; or,  
b) Accompany it with a written offer, valid for at least three years, to give  
any third party, for a charge no more than your cost of physically  
performing source distribution, a complete machine-readable copy of  
Regulatory Notices - 8  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Regulatory Notices  
the corresponding source code, to be distributed under the terms of  
Sections 1 and 2 above on a medium customarily used for software  
interchange; or,  
c) Accompany it with the information you received as to the offer to  
distribute corresponding source code. (This alternative is allowed only  
for noncommercial distribution and only if you received the program in  
object code or executable form with such an offer, in accord with  
Subsection b above.)  
The source code for a work means the preferred form of the work for making  
modifications to it. For an executable work, complete source code means all  
the source code for all modules it contains, plus any associated interface  
definition files, plus the scripts used to control compilation and installation of  
the executable. However, as a special exception, the source code distributed  
need not include anything that is normally distributed (in either source or  
binary form) with the major components (compiler, kernel, and so on) of the  
operating system on which the executable runs, unless that component itself  
accompanies the executable.  
If distribution of executable or object code is made by offering access to copy  
from a designated place, then offering equivalent access to copy the source  
code from the same place counts as distribution of the source code, even  
though third parties are not compelled to copy the source along with the object  
code.  
4. You may not copy, modify, sublicense, or distribute the Program except as  
expressly provided under this License. Any attempt otherwise to copy,  
modify, sublicense or distribute the Program is void, and will automatically  
terminate your rights under this License. However, parties who have received  
copies, or rights, from you under this License will not have their licenses  
terminated so long as such parties remain in full compliance.  
5. You are not required to accept this License, since you have not signed it.  
However, nothing else grants you permission to modify or distribute the  
Program or its derivative works. These actions are prohibited by law if you do  
not accept this License. Therefore, by modifying or distributing the Program  
(or any work based on the Program), you indicate your acceptance of this  
License to do so, and all its terms and conditions for copying, distributing or  
modifying the Program or works based on it.  
6. Each time you redistribute the Program (or any work based on the  
Program), the recipient automatically receives a license from the original  
licensor to copy, distribute or modify the Program subject to these terms and  
conditions. You may not impose any further restrictions on the recipients'  
exercise of the rights granted herein.  
You are not responsible for enforcing compliance by third parties to this  
License.  
7. If, as a consequence of a court judgment or allegation of patent infringement  
or for any other reason (not limited to patent issues), conditions are imposed  
on you (whether by court order, agreement or otherwise) that contradict the  
Regulatory Notices - 9  
Download from Www.Somanuals.com. All Manuals Search And Download.  
User Guide V2IU 6400-S Converged Network Appliance  
conditions of this License, they do not excuse you from the conditions of this  
License. If you cannot distribute so as to satisfy simultaneously your  
obligations under this  
License and any other pertinent obligations, then as a consequence you may  
not distribute the Program at all. For example, if a patent license would not  
permit royalty-free redistribution of the Program by all those who receive  
copies directly or indirectly through you, then the only way you could satisfy  
both it and this License would be to refrain entirely from distribution of the  
Program.  
If any portion of this section is held invalid or unenforceable under any  
particular circumstance, the balance of the section is intended to apply and the  
section as a whole is intended to apply in other circumstances.  
It is not the purpose of this section to induce you to infringe any patents or  
other property right claims or to contest validity of any such claims; this  
section has the sole purpose of protecting the integrity of the free software  
distribution system, which is implemented by public license practices. Many  
people have made generous contributions to the wide range of software  
distributed through that system in reliance on consistent application of that  
system; it is up to the author/donor to decide if he or she is willing to  
distribute software through any other system and a licensee cannot impose  
that choice.  
This section is intended to make thoroughly clear what is believed to be a  
consequence of the rest of this License.  
8. If the distribution and/or use of the Program is restricted in certain  
countries either by patents or by copyrighted interfaces, the original copyright  
holder who places the Program under this License may add an explicit  
geographical distribution limitation excluding those countries, so that  
distribution is permitted only in or among countries not thus excluded. In  
such case, this License incorporates the limitation as if written in the body of  
this License.  
9. The Free Software Foundation may publish revised and/or new versions of  
the General Public License from time to time. Such new versions will be  
similar in spirit to the present version, but may differ in detail to address new  
problems or concerns.  
Each version is given a distinguishing version number. If the Program  
specifies a version number of this License which applies to it and "any later  
version", you have the option of following the terms and conditions either of  
that version or of any later version published by the Free Software Foundation.  
If the Program does not specify a version number of this License, you may  
choose any version ever published by the Free Software Foundation.  
10. If you wish to incorporate parts of the Program into other free programs  
whose distribution conditions are different, write to the author to ask for  
permission. For software which is copyrighted by the Free Software  
Foundation, write to the Free Software Foundation; we sometimes make

exceptions for this. Our decision will be guided by the two goals of preserving  
the free status of all derivatives of our free software and of promoting the  
sharing and reuse of software generally.  
NO WARRANTY  
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS  
NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY  
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING  
THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE  
PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER  
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE  
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A  
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND  
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE  
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL  
NECESSARY SERVICING, REPAIR OR CORRECTION.  
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED  
TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER  
PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS  
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING  
ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL  
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE  
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR  
DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY  
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO  
OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR  
OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH  
DAMAGES.
