x610 Series Layer 3 Gigabit Ethernet Switches Installation Guide

AT-LBM (Loop Back) Module

The x610-48Ts/X and x610-48Ts/X-POE+ switches are shipped from the

factory with an AT-LBM module installed in the expansion slot on the rear

panel, as shown in Figure 29. This module is factory installed for the

non-stacking configuration. It provides the capability for a full line rate,

non

-blocking switching configuration when there are connections on the

x610-48Ts/X and x610-48Ts/X-POE+ switches to all 44 copper ports, two

SFP ports, and two SFP+ ports. If you need to configure the switch for

stacking, you may install a VCStack stacking module in place of the

AT-LBM Module.

Note

The AT-LBM module is very similar to a blank panel in its outward

appearance except that it is marked with the “AT_LBM” model name

in the upper left-hand corner of the faceplate.

If the AT-LBM module is replaced with either an AT-StackXG or

AT-x6EM/XS2 stacking module, the switching configuration is no

longer non-blocking.
