x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
AT-LBM (Loop Back) Module
The x600-48Ts/XP switch is shipped from the factory with an AT-LBM module installed in its expansion slot on the rear panel as shown in Figure 21.This module is factory installed for the non-stacking configuration. It provides the capability for a full line rate, nonblocking switching configuration when there are connections on the x600-48Ts/XP switch to all 44 copper ports, two SFP ports, and two XFP ports. If you need to configure the switch for stacking, you may install a VC Stacking Module (AT-StackXG) in place of the AT-LBM Module.
