Replacing an SP
RAID Instructions 3-25
Replacing an SP
You can replace a failed SP without powering down the storage chassis. However,
you will need to re-boot the operating system software once you install the
replacement SP.
Removing an SP
IMPORTANT If you must replace a failed SP and you do not have a
replacement, leave the failed SP installed until the replacement is available. Do
not operate the chassis with an open SP slot. Either leave the failed SP installed
or install an SP filler board.
You can remove an SP while the storage chassis is powered up. However, to avoid
automatic thermal shutdown of the storage chassis, you must complete Steps 2
through 5 within two minutes. Before you begin to remove an SP, make sure that you
understand all the steps in the following procedure.
To remove an SP:
1. Read Avoiding Electrostatic Discharge (ESD) Damage at the beginning of this
chapter.
2. Open the fan module.
3. Attach the clip of the ESD wrist band (strap) to the grounded chassis and put the
wrist band around your wrist with the metal button against your skin.
WARNING: Some components on the SP become hot during operation. To prevent
personal injury, make sure that you do not touch components on the SP when you
remove it.
