Operations for Trained Service Personnel
Caution Only trained and qualified personnel should install or replace equipment in this
section..Replacement procedures in this section require an awareness of electrical shock
hazards and, in the case of cooling fans, possible mechanical hazards from rotating fan
blades.
Remove/Replace the Top Panel
You must remove the restorer top panel to access all replacement parts other than power supply
units and disks. If the restorer is in a rack with another box directly above, the restorer may need to
be removed from the rack to remove the top panel. Always use two people when moving a restorer,
as the system weighs 88 pounds (40 kilograms).
The only tool needed to remove and replace a top panel is a Phillips #2 screwdriver.
