Power Budgeting The power for PoE on the ports on the AT-SBx81GP24 Line Card is

provided by the AT-SBxPWRPOE1 Power Supply. It can provide up to
1200 watts of power for powered devices. You may install up to two power
supplies in the chassis for a total of 2400 watts for the powered devices.
The number of powered devices the chassis can support at one time
depends on the number of AT-SBxPWRPOE1 Power Supplies in the
chassis and the power requirements of the powered devices in your
network. Table 14 lists the maximum number of powered devices by class,
for one or two power supplies. The numbers assume that the powered
devices require the maximum amount of power for their classes.
Note
The maximum number of PoE ports in the SwitchBlade x8112
Switch is 240 ports.

PoE Wiring The IEEE 802.3af and 802.3at standards define two methods for

delivering power to powered devices over the four pairs of strands that
comprise a standard Ethernet twisted-pair cable. The methods are called
Alternatives A and B. In Alternative A, power is supplied to powered
devices on strands 1, 2, 3, and 6, which are the same strands that carry
the 10/100Base-TX network traffic. In Alternative B, power is delivered on
strands 4, 5, 7, and 8. These are the unused strands.
Note
1000BASE-T cables carry the network traffic on all eight strands of
the Ethernet cable.
The PoE implementation on the AT-SBx81GP24 Line Card is Alternative
A. Power is transmitted on strands 1, 2, 3, and 6.
