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.
