Expansion Modules

Several different hardware accessories are available for expanding the capabilities of your Extreme Networks switch. Collectively, they are referred to as expansion modules.

Port option cards and versatile interface modules (VIMs) are installed in dedicated slots at the back of the switch to provide optional I/O ports or stacking ports. These optional items add 10-Gbps copper or fiber I/O ports to the back panel of compatible switches. If no card or module is installed, the option slot is covered by a blank panel.
The TM-CLK Clock Module is required for Synchronous Ethernet (SyncE) processing on the X460-G2 switch.

The following table lists the types of expansion modules and the switch series with which they are compatible.
