PS6000 Hardware Maintenance Maintaining Power Supply Modules
4–2
• Group Manager GUI and CLI output. The GUI Member Enclosure
window or the CLI
member select show enclosure command shows a
power supply and cooling module failure.
In the Group Manager GUI, the CLI output, and the event messages, the power
supply and cooling modules are identified as follows:
• Module 0 refers to the module on the right side of the array back panel (when
facing the back of the array)
• Module 1 refers to the module on the left side.
See Figure 1-2 on page 1-2 for details.
Removing a Power Supply and Cooling Module
If a power supply and cooling module fails, you must replace the module as soon
as possible, although an array can operate with only one working module. For
proper array cooling, do not remove a failed module until you are ready to replace
it.
You can remove a power supply and cooling module from an array without
affecting array operation if the second module is installed and functioning.
Otherwise, if possible, cleanly shut down the array before removing the module,
as described in Shutting Down and Restarting an Array on page 1-5.
Caution: Wear electrostatic protection when handling a power supply and
cooling module. See Using an Electrostatic Wrist Strap on page 1-5.
To remove a power supply and cooling module:
1. Turn off power to the module.
2. Disengage the power cable strain relief and disconnect the power cable.
3. See Figure 4-2. Squeeze the latches inward ( ) to release the handle and then
rotate the handle upward ( ).
