Redundant hot-plug fans

The server supports redundant hot-plug fans to provide proper airflow to the system if a primary fan fails.

In the standard configuration, primary fans 2, 4, and 6 cool the server.

For the redundant configuration, fans 1, 3, and 5 are added to back up the primary fans. This

configuration allows the server to continue operation in non-redundant mode if a fan failure occurs.

For fan locations, refer to Hot-Plug Fan locations ("Fan locations" on page 25).

WARNING: To prevent personal injury from hazardous energy:

• Remove watches, rings, or other metal objects.

• Use tools with insulated handles.

• Do not place tools or metal parts on top of batteries.

Installing hot-plug fans

Redundant hot-plug fans can be inserted at any time, including when the server is operating.

For full redundancy, all fans must be installed.

For fan locations, refer to Fan Locations (on page 25).

1. Extend the server from the rack, if applicable ("Extending the server from the rack" on page 27).

2. Remove the access panel ("Access panel" on page 31).
