Removing and replacing a drive blank

Use the following procedures to remove a faulty drive slot filler and replace it with a new one from stock.
Drive slot fillers are passive components that regulate airflow through the control enclosure.
Notes:
• Every drive slot of an operational control enclosure must contain either a drive or a drive slot filler. A
drive slot must not be left empty for more than 10 minutes during servicing. Ensure that you have read
and understood the removal and replacement instructions, and have the replacement part unpacked
before you remove the existing drive slot filler.
• No tools are required to complete this task. Do not remove or loosen any screws.
1. Unpack the replacement drive slot filler from its packaging.

Removing and replacing a power supply unit

You can remove and replace either of the two hot-swap redundant power supply units (PSUs) in an IBM
Elastic Storage System 3000 control enclosure. These redundant power supplies operate in parallel, one
continuing to power the enclosure if the other fails.
Notes:
• This procedure requires access to either management GUI or CLI command as a root user. IBM service
personnel need to coordinate with the customer to work on this procedure.
