3.7 Removing the Front Cover of the Sun Fire
X4100/X4100 M2 Server
1. Open the door to the fan bay. See FIGURE 3-5.
2. While holding the fan bay door open, slide the front cover toward the front of
the chassis approximately 0.25 inch (6 mm).
3. Raise the rear edge of the cover first, and then lift it off the chassis.
Note – When you remove any cover, the intrusion switch that is on the front I/O
board automatically powers down the system to standby power mode.
Note – When you replace the front cover, place the front edge on the chassis first,
then set it down into the keyed slots on the chassis sides before sliding it back.
Note – For Sun Fire X4100 servers with the factory-configured option for four hard
disk drives: You must remove the top two hard disk drives before reinstalling the
front cover to provide clearance for the front cover to slide on the chassis. Reinstall
the top two hard disk drives after you reinstall the front cover.
