AT-SBxPWRPOE1 Power Supply
The AT-SBxPWRPOE1 Power Supply, shown in Figure 24, provides the
PoE power for the ports on the AT-SBx81GP24 PoE Line Cards. You may
install either one or two PoE power supplies in the chassis.
The AT-SBxPWRPOE1 Power Supply provides 1200 watts of power for
PoE. You may install two power supplies in the chassis for a total of 2,400
watts of power.
The total number of powered devices the chassis can support depends on
the number of AT-SBxPWRPOE1 Power Supplies in the chassis and the
power requirements of the devices. For instance, a chassis can support 40
ports of Class 4, PoE+ (IEEE 802.3at) powered devices with one power
supply or 80 ports with two power supplies. For further information, refer to
Table 4 on page 36.

Power supply modules are not included with the chassis and must be
purchased separately.
The AT-SBxPWRPOE1 Power Supplies are installed in the two left hand
slots, labeled A and B, at the top of the front of the chassis. If you are
installing only one power supply, you may install it in either slot. The
locations of the slots are shown in Figure 8 on page 24.
The AT-SBxPWRPOE1 Power Supply is hot swappable. You do not have
to power off the chassis to install or remove the power supply.
