Installing Slide Rail Lock Nuts

Note – Slide rail lock nuts are preinstalled on all units shipped from the factory in a cabinet.

For servers not shipped preinstalled in a cabinet, a slide rail mounting kit containing lock nuts, spacers, and rails is used to mount and secure a server in a cabinet. See “Installing Slide Rails” on page 4. Once the locking nuts are installed on the server, the following is applicable:

■Lock nuts must be loosened in order to remove a server from a cabinet.

■Lock nuts must be securely tightened on each server prior to moving a cabinet with one or more servers.

Proceed as follows to install the slide rail lock nuts:

Note – The slide rail mounting kits contain a pair of spacers provided by the manufacturer along with the rails. The manufacturer’s spacers must be discarded and replaced by the Sun spacers provided in the kit.
