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 chassis is running (hot-swap) or must be powered off (cold-swap). References are provided for more detailed information.

Note: Depending on the blade configuration of the chassis and the number of power supplies installed, the chassis may be able to continue operating while you replace a power supply. See "Power Supply Requirements" in Brocade X7 Director Technical Specifications 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 chassis will start powering down blades until the power demand can be met.

Installing an Additional Power Supply (Hot-Install)

If your chassis is up and running, has empty slots for power supplies, and you want to install additional power supplies, complete the following steps:

  1. Remove the filler panel from the empty power supply assembly slot.
  2. Insert the new power supply assembly.
  3. Plug the power cord into the new power supply assembly from the power source.
  4. Verify the power supply assembly status LED.

Replacing a Power Supply Assembly (Hot-Swap)

If your chassis is up and running, but the 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-swapping. See "Power Supply Specifications" and "Power Supply Requirements" in Brocade X7 Director Technical Specifications for minimum power supplies required for low and high voltage line operation.
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-swapping.
  1. Unplug the power cable from failed power supply assembly.
  2. Remove the power supply assembly.
  3. Insert new power supply assembly.
  4. Plug the power cord into a new power supply assembly from the power source.
  5. Verify the power supply assembly status LED.

Replacing or Installing a Power Supply Assembly (Cold-Install or Cold-Swap)

If your chassis is up and running, but you want to power down the chassis to install additional power supply assemblies or replace failed power supply assemblies, complete the following steps:

  1. Shut down the system using the sysShutdown command.
  2. Unplug power cords from all power supply assemblies.
  3. If adding a power supply assembly, remove the filler panel from the empty power supply assembly slot.
  4. Install or replace power supply assemblies.
  5. Plug power cords into all power supply assemblies from power sources.
  6. Verify the power supply assembly status LEDs.
