6. To reinstall the cooling shroud, do the following:
a. Ensure that:
• All components have been reassembled correctly.
• No tools or loose screws are left inside your server.
• All cables inside the server have been properly routed and they will not interfere with installing
the cooling shroud.
b. Note the orientation of the cooling shroud. Align the tabs on both sides of the cooling shroud with
the corresponding holes or gaps in both sides of the chassis.
c. Lower the cooling shroud into the chassis until it snaps into position.
Note: If necessary, gently press the cooling shroud on both sides so that the tabs on the cooling shroud
completely engage with both sides of the chassis.

Installing or replacing a system fan

Attention: Do not open your server or attempt any repair before reading and understanding "Safety information"
on page iii and "Guidelines" on page 67.
Your server supports up to six hot-swap system fans. This design helps you avoid significant cooling
problems when a system fan fails. You can replace a system fan without turning off the server. To locate the
system fans, see "System board components" on page 44.
