Switch Fabric Modules
3CB9FG24T — 24-Port
Gigabit Ethernet Switch
Fabric Module —
■
backplane ports 1 – 24:
enabled (all slots) See Table XX for how ports are
connected to other slots in the
chassis.
3CB9FG9 — 9-Port Gigabit
Ethernet Switch Fabric
Module Ports 7 – 9 are
enabled when
GBICs are installed.
■
backplane ports 1 – 6:
enabled (all slots) See Table XX for how ports are
connected to other slots in the
chassis.
Layer 2 Switching Modules
