Chapter 1: Overview

Note

Given that the AT-SBxPWRSYS1 DC Power Supply is not compatible with the AT-SBxPWRPOE1 AC Power Supply, a chassis that contains one or more AT-SBx81GP24 PoE Line Cards should use the AT-SBxPWRSYS1 AC Power Supply, and not the DC module, as the system power unit.

LEDs The LEDs on the power supply are described in Table 16.
