Apple Xserve (Original) - Manual (Page 31)

Installing Your Server in a Rack 31
2 Screw the flanges at the front of the cover to the front rails of the rack
Be careful not to overtighten the flange screws. Doing so could change the shape of the
cover slightly and make it difficult to slide the server into the cover.
Some racks have prethreaded holes and some have square holes that take clips with attached
nuts. You may need to insert a clip (not provided with the server) into the appropriate hole
before attaching the screw.
Attach the cover to the two
front rack mounting posts using
four of the screws provided.
Some racks have
pre-threaded holes. Other racks use various
types of removable,
captive nuts to secure
equipment.
