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.
