4-Port Gigabit Ethernet Layer 3 Switching Module (GBIC) Quick Start Guide

Installation in an 8-slot Chassis
You can choose any slot in the 8-slot chassis to house a 4-port Gigabit
Ethernet Layer 3 Switching Module (GBIC) — except slots 7 and 8 which
are for the wider switch fabric modules, and slots 9 and 10, which are for
the smaller management modules.
Table 3 and Table 4 show the relationship among the GEN Switch Fabric
Modules (24-port or 9-port) and the 4-port Gigabit Ethernet Layer 3
Switching Module (GBIC) when both are installed in an 8-slot chassis. To
summarize the table:
■
The switching module can use all four of its backplane ports in slots
1 – 6, when used in conjunction with a 24-port GEN Switch Fabric
Module (3CB9FG24 or 3CB9FG24T). 3Com recommends that you
install this Layer 3 switching module in any of those slots.
■
The switching module can use only its first backplane port (module
port number 5) when used in conjunction with a 9-port GEN Switch
Fabric Module (3CB9FG9).
Table 3 and Table 4 also show the relationship between the GEN Switch
Fabric Module backplane port numbers and the corresponding LED
indicator numbers.
