To access some components and perform certain service procedures, you must perform one or more of the following procedures:
If you are performing service procedures in an HP, Compaq branded, telco, or third-party rack cabinet, you can use the locking feature of the rack rails to support the server and gain access to internal components.
For more information about telco rack solutions, refer to the RackSolutions.com website.
If you must remove a server from a rack or a non-hot-plug component from a server, power down the server.
If the rack environment, cabling configuration, or the server location in the rack creates awkward conditions, remove the server from the rack.
