The AT-SBx3161 System Power Supply provides the power for all 
components installed in the SwitchBlade x3112 Switch including power for 
the chassis backplane, two AT-SBx31CFC Fabric Control Cards, up to ten 
Ethernet line cards and the Fan Tray. See Figure 15. Two slots are 
available in the AT-SBx3112 Chassis for the installation of a primary and a 
redunant AT-SBx3161 System Power Supply.

The AT-SBx3161 features a hot swappable design, which allows you to 
interchange power supplies without causing electronic damage to the 
system components or the power supply itself.
