Remove a CPU/IO module
You may remove either CPU/IO module from the rack-mounted enclosure for exchange if required.
Please note the following precautions before doing so:
- Power down the CPU/IO module you are replacing by removing the AC line cord from the rear of that module. When installed, the AC line cords are held in place by stopper bars preventing the removal of the CPU/IO module.
- Have at least two people available to remove a CPU/IO module.
- If you are removing a failed CPU/IO module for exchange, after you have removed the CPU /IO module, you must remove all hard drives in their caddies from the failed module. You must label the hard drives with their drive slot location numbers as you remove them. They must be re-installed in the same hard drive slots when the exchange CPU/IO module is received from the factory. If not, the mirrored hard drives will be out of sync.
Remove either CPU/IO module as described below.
