Opening The System; Closing The System - Dell PowerEdge R300 Hardware Owner's Manual

Opening the System

To upgrade or troubleshoot the system, remove the system cover to gain
access to internal components.
1 Unless you are installing a hot-plug component such as a power supply,
turn off the system and attached peripherals, and disconnect the system
from the electrical outlet and peripherals.
2 To remove the system cover, turn the latch release lock counter-clockwise
to the unlocked position. See Figure 3-4.
3 Lift up on the latch on top of the system. See Figure 3-4.
4 Grasp the cover on both sides and carefully lift the cover away from the
system.

Closing the System

1 Lift up the latch on the cover.
2 Place the cover on top of the system and offset the cover slightly back so
that it clears the chassis J hooks and lays flush on the system chassis. See
Figure 3-4.
3 Push down the latch to lever the cover into the closed position.
4 Rotate the latch release lock in a clockwise direction to secure the cover.
