Inserting an ESM

Verifying component operation

After replacing the ESM, verify that the CRU OK LED (rear panel) illuminates green, indicating that the 

ESM is online/operating normally. It may take two to five minutes for the replacement ESM to become 

ready.

Replacing a disk drive module

A disk drive module consists of a disk in a sled. Disk drive modules are hot-swappable, which means they 

can be replaced without halting I/O to the arrays or powering off the enclosure. The new disk drive 

module must be of the same type, and possess capacity equal to or greater than the one being replaced.

NOTE:

Remove the bezel to access drives and drive blanks. Reattach the bezel when finished viewing 

them (see 

Attaching and removing the enclosure bezel

 on page 42).

Drive blanks

When installed, a drive blank looks like a disk drive module; however, it is an empty box used to maintain 

optimal air flow for proper cooling within the enclosure. Drive blanks are installed in slots missing disk 

drive modules. If you must remove a disk drive module, but cannot immediately replace it, you must either 

leave the faulty module in place, or insert a drive blank in its place.
The drive blank is installed using the same procedure as 

Installing a disk drive module

 on page 48. 

Similarly, the drive blank is removed using the same procedure as 

Removing a disk drive module

 on 

page 47.

Before you begin

CAUTION:

Removing a disk drive module impacts the airflow and cooling ability of the enclosure. If the 

internal temperature exceeds acceptable limits, the enclosure may overheat and automatically shut down 

or restart. To avoid potential overheating, wait 20 seconds to allow the internal disks to stop spinning, then 

insert the new disk drive module.

See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on 

page 40
