Power supply assembly task guide

This section contains a guide to more complete, detailed steps in this section for
installing or replacing power supply assemblies when the device is running (hot
swap) or must be powered off (cold swap). References are provided to the more
detailed removal and installation steps for further information.
Note: Depending on the blade configuration of the device and the number of
power supplies installed, the device may be able to continue operating while
replacing a power supply. Refer to "Power Supply Requirements" in Appendix B,
"Product specifications," on page 235 for minimum power supplies required for
AC low and high voltage line operation, redundancy in case of power supply
failure, and other specifications. If there is insufficient power, the device will start
powering down blades until the power demand can be met.
Installing additional power supply (hot-install)
If your device is up and running, has empty slots for power supplies, and you
want to install additional power supplies, complete the following steps.
1. Remove filler panel from empty power supply assembly slot.
2. Insert the new power supply assembly.
3. Plug power cord into the new power supply assembly from power source.
4. Verify power supply assembly status LED.
Replacing power supply assembly (hot-swap)
If your device is up and running, but a power supply has failed, complete the
following steps.
Note: Removing more than one power supply could result in insufficient system
power which could cause some blades to power down. Ensure that there is an
adequate number of active power supply assemblies when removing a single
power unit during hot-swap. Refer to "Power supply specifications" and "Power
supply requirements" in Appendix B, "Product specifications," on page 235 for
minimum power supplies required for low and high voltage line operation.
1. Unplug power cable from failed power supply assembly.
2. Remove power supply assembly.
3. Insert new power supply assembly.
4. Plug power cord into new power supply assembly from power source.
5. Verify power supply assembly status LED.
