Replacing A Power Supply Unit For An Expansion Enclosure - IBM Storwize V7000 Troubleshooting And Maintenance Manual

Replacing a power supply unit for an expansion enclosure

You can replace either of the two 580 watt hot-swap redundant power supplies in the expansion
enclosure. These redundant power supplies operate in parallel, one continuing to power the canister if
the other fails.

Attention: If your system is powered on and performing I/O operations, go to the management GUI
and follow the fix procedures. Performing the replacement actions without the assistance of the fix
procedures can result in loss of data or access to data.
Attention: A powered-on enclosure must not have a power supply removed for more than five minutes
because the cooling does not function correctly with an empty slot. Ensure that you have read and
understood all these instructions and have the replacement available, and unpacked, before you remove
the existing power supply.
Even though many of these procedures are hot-swappable, these procedures are intended to be used only
when your system is not up and running and performing I/O operations. Unless your system is offline,
go to the management GUI and follow the fix procedures.
To connect:
1. Turn off everything (unless instructed otherwise).
2. Attach all cables to the devices.
3. Attach the signal cables to the connectors.
4. Attach the power cords to the outlets.
5. Turn on the devices.
