Air Shrouds
Air shrouds concentrate airflow to maximize fan efficiency. The SYS-240P-TNRT includes
three different sets of air shrouds.
Caution:
DO NOT perform this service with the system mounted inside the rack.
Air Shroud for Memory (CPU1/2)
Four 2U air shrouds cool the DIMM slots controlled by CPUs 1 and 2 (see figure below).
1. Power down the system as described in Section 3.1.
2. Remove the system from the rack and place it on a bench, then remove the cover as
described
3. Place each air shroud over six DIMM slots at a time for both CPU1 and CPU2-controlled
DIMM slots, as illustrated below.
4. Close the cover and push the system back into the rack.

Caution:
The handles used for pulling the system from the rack are not intended to be used
to pick up or lift the system.
