Chapter 3 Removing and Replacing Hot-Swappable Components 43
Installing a Power Supply
The system’s power supply hot-swap feature enables you to insert a power supply
without shutting down the operating system or turning off the system power.
When installing a power supply, you must insert the power supply and wait for the
two green power supply LEDs to light.
The following procedure assumes that you are accessing the system console by the
default method of connecting to the serial management port (SERIAL MGT) of the
Netra 440 server.
Caution – You have limited time to perform a power supply hot-swap operation.
You have 10 minutes at sea level and a maximum of 7 minutes at 10,000 feet (3048
meters) to ensure proper system cooling.
1. Align the new power supply with its bay.
2. Slide the PSU into the server until you feel it engage with the power distribution
board inside.
Ensure that the lever does not return to a rightmost position until the power supply
engages with the power distribution board. If the lever does return early, the power
supply will not engage correctly.
Caution –
There are several pinch points on the power supply, so use caution when
removing or installing a power supply in the system. Refer to the caution label on
the power supply for more information.
3. Press the lever to the left until it clicks.
Returning the lever to a leftmost position engages the power supply with the power
distribution board inside the server.
4. Connect the DC or AC power cable to the power supply.
5. Verify that the power supply is operating correctly.
Check the Service Required, OK-to-Remove, and Power OK LEDs on the power
supply. You should hear the power supply fan start spinning and the two green
LEDs should light within three seconds after completing a hot-swap installation.
For more information on the power supply LEDs, refer to “Power Supply LEDs” on
page 15 .
