When you remove an I/O module (IOM), you disconnect the
SAS cables, and slide the IOM out of the drive shelf.
You have an ESD wristband, or you have taken other antistatic
precautions
You have the replacement IOM.
- Put on antistatic protection.
- Unpack the new IOM, and set it on a level surface near
the drive shelf.
Save all packing materials for use when returning the failed
IOM.
- Label each cable that is attached to the IOM.
- Disconnect all of the cables from the IOM.
- Squeeze the latch on the cam handle until it releases,
and then open the cam handle to the right to release the IOM from
the midplane.
- Using two hands, pull the IOM out of the disk shelf.
When you remove the IOM, a flap swings into place to block
the empty bay, helping to maintain air flow and cooling.
