Getting Started
20 Installing the S6200, S6500, and S6800 Conferencing Server
Maintenance Modem
A direct dial phone line must be dedicated to each maintenance modem. A regular phone line
should be used. The maintenance modems enable Avaya personnel to dial into the system
directly for remote support such as running diagnostics, troubleshooting, or updating software.
All servers use a Multitech modem with a standard DB9 cable.
LAN Cabling
All components have dual 10/100/1000 Ethernet LAN connections. Each interface connects to
an Ethernet network by up to 100 meters of Category 5 or 5e cable. One connection is used for
the control network and the other is used for the media network. (Both networks may be the
same.)
The network should be partitioned to keep average network traffic levels to 60% utilization or
less. Additionally, the LAN cabling must comply with all national codes.
Keep cable runs between systems and concentrators short and reasonably clear of electrical
noise sources such as motors and fluorescent lighting. The specifications for the amount of
disturbance that can be introduced into the link between the system and the concentrator are
defined in the 8802.3 standard. The link must meet these specifications including all connectors
and patch cables.
You can measure compliance directly by using cable testers from third parties specifically
designed for qualifying 10/100 Base-T links. These testers verify the physical characteristics of
the cable and connectors and can perform the tests for noise specified in the 8802.3 standard to
verify that the link can provide reliable operation.
!
CAUTION:
CAUTION:
Do not use “Silver Satin” cable for any portion of the link. It does not meet the
requirements for 10BaseT transmission.
