Access panel
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: For proper cooling, do not operate the server without the access panel, baffles,
expansion slot covers, or blanks installed. If the server supports hot-plug components, minimize
the amount of time the access panel is open.
To remove the component:
1. Power down the server if performing a non-hot-plug installation or maintenance procedure ("Power
down the server" on page 24).
2. Extend the server from the rack (on page 25).
3. Use the T-15 Torx screwdriver attached to the rear of the server to loosen the security screw on the hood
latch.
4. Lift up on the hood latch handle, and then remove the access panel.
To replace the component, reverse the removal procedure.
