Replacing the Enclosure
Printed circuit board components are sensitive to electrostatic
discharge. To prevent operating failure or damage, observe the
following: Establish a ground for yourself by using a wrist grounding
strap, or by touching the metal chassis prior to handling or installing
a printed circuit board component.
Remove your replacement enclosure from the shipping container and inspect
the shipment. Save the packaging material.
Power down the host computer and the storage enclosure(s).
Refer to the procedures described to power down the host computer system
in your user's guide and "Powering Off the Storage System" on page 102 for
the enclosure.
NOTE:
Mark or make a notation of the location of the data cables prior to
disconnecting or removing these items. To facilitate correct
installation, you may want to tag the cables appropriately.
Disconnect the FC data cables, ethernet cables, and power cords/cables from
the faulty storage enclosure.
Remove the front bezel.
Remove each power supply.
Remove the cooling fan module.
Remove each RAID Controller, noting its position. You may wish to tag the
controllers for proper installation.
Remove the SES Controller card, Disk I/O cards, and Host I/O cards.
NOTE:
Be sure to note the position of the switches on the SES Controller
card and Host I/O card, as well as the jumper settings on the Host
I/O card and Disk I/O card. This is a precautionary measure in the
event they would accidently get changed.
