A single AT-SBxPWRSYS1 Power Supply has enough power to support a
fully populated chassis. However, you may install two power supplies to
add power redundancy to the chassis.
The two left hand slots are for the AT-SBxPWRPOE1 Power Supply. This
unit provides PoE for the ports on the AT-SBx31GP24 Line Card. (It
should be noted that the line card also needs the AT-SBxPWRSYS1
Power Supply to operate its switching functions.) You may install two AT-
SBxPWRPOE1 Power Supplies in the chassis to increase the amount of
available PoE power or to add PoE redundancy.
Note
The AT-SBxPWRSYS1 DC Power Supply is not compatible with the
AT-SBxPWRSYS1 AC or AT-SBxPWRPOE1 AC Power Supply.
You should not operate the chassis with both AC and DC power
supplies. You may, however, operate the chassis for a short period
of time with AC and DC power supplies if you are converting it from
one type of power supply to another, such as from AC to DC. This
allows you to transition the chassis without having to power it off.
