Note
To avoid installing both AC and DC power supplies in the same
chassis, you should use the AT-SBxPWRSYS1 AC Power Supply,
and not the DC module, as the system power unit if the chassis
contains one or more AT-SBx81GP24 PoE Line Cards.
LEDs The LEDs on the power supply are described in Table 16.
