Installing the Redundant Hot-Plug Fan Cage
The redundant hot-plug fan cage is installed inside the chassis, directly above the

the redundant hot-plug fan cage option kit.
To install the redundant hot-plug fan cage:
1. Power down the server. Refer to "Powering Down the Server" in this chapter.
2. Remove the access panel. Refer to "Removing the Access Panel" in this chapter.
3. Loosen the two thumbscrews on the redundant fan cage retaining bracket (1).
4. Remove the bracket from the chassis (2).
IMPORTANT: Do not discard the fan cage retaining bracket. The bracket is required for
proper fan operation.
