Replacing a Power Supply

The appliance has two power supplies, supplying hot-pluggable power redundancy. The system distributes the power load across both power supplies to maximize efficiency. When a power supply is removed with the system powered on, the full power load is picked up by the remaining power supply.

Note

The system requires one power supply to operate normally. Remove and replace only one power supply at a time in a system that is powered on.

Note

The system ships with just one power supply and you have the option to purchase the additional power supply (Ordering Part No. 30522 WS-PSI-C5215-750W-01).

Each power supply has a single bi-color LED to indicate power supply status, as described in the following table:

Power Supply Status LED Indicator Patterns

LED Pattern	Power Supply Condition
Green	Output on and OK
Off	No AC power to all power supplies
1Hz Blinking Green	AC present / Only 12VSB on (PS off) or PS in cold redundant state
Amber	AC power cord unplugged or AC power lost. With a second PS in parallel still with AC input power
1Hz Blinking Amber	Power supply warning events where PS continues to operate — high temp, high power, high current, slow fan
Amber	Power supply critical event causing a shutdown, failure, OCP, OVP, fan fail
2Hz Blinking Green	Power supply firmware updating
