Power LEDs
On the front of the switch, the Power LED on the management panel indicates the
general status of the power supplies. The LED flashes when only one power cord is
connected, and is steady when both power cords are connected (see “System Status
LEDs” on page 24 ).
Additional LED indicators are located on the rear panel of the switch, on the
individual power supply modules. The following table describes the power supply
module LED behavior.
