Check Power Supply Status LEDs
The power supply status LEDs are located on the power supply at the front of the
chassis. See
“Front Panel LEDs” on page 2
.
1. Visually inspect the power supply’s status LEDs.
2. Compare what you see on the power supply to this table.
Caution –
If a power supply has shut down because of a thermal or overcurrent
condition, signified by the amber Attention LED lighting, remove the respective
power cord from the chassis. Allow the power supply to completely cool for at least
15 minutes. A shorter cooling time might cause damage to the power supply when
the power cord is reattached. If the Attention LED lights amber upon reattaching the
power cord, replace the power supply.
3. If the Attention LED is lit, there is a fault with that power supply.
