Supervisor Engine Console Port Cabling Specifications; Port Connector Requirements - Cisco 7603 - Modular Expansion Base Installation Manual

Determining Cable Distances
A significant variation in the amount of DMD is produced from one MMF cable to the next. No
reasonable test can be performed to survey an installed cable plant to assess the effect of DMD.
Therefore, you must use the mode-conditioning patch cords for all uplink modules using MMF when the
link span exceeds 984 feet (300 meters). For link spans less than 300 meters, you can omit the patch cord
(although there is no problem using it on short links).
For link spans less than 984 feet (300 meters), you can omit the patch cord. (We do not recommend using
Note
the LX/LH GBIC and MMF without a patch cord for very short link distances less than 100 meters. The
result could be an elevated bit error rate [BER].)

Supervisor Engine Console Port Cabling Specifications

This section describes the port cabling specifications for the supervisor engine.
Note The accessory kit that shipped with your Cisco 7600 series routers contain the necessary cable and
adapters to connect a terminal or modem to the front-panel console port of the supervisor engine. These
cables and adapters are the same as those shipped with the Cisco 2500 series routers and other Cisco
products.
The supervisor engine front-panel console port mode switch allows you to connect a terminal or modem
to the console port using the cable and adapters provided, or you can connect your terminal using a
Catalyst 5000 family Supervisor Engine III cable (not provided).
