Install the Controllers Into the Slide-Rail Assemblies

Language:

Use this procedure to install each controller chassis, with mounting brackets, into the slide-rail assemblies that are mounted to the rack.

Caution - This procedure requires a minimum of two people because of the weight of the controller. Attempting this procedure alone could result in equipment damage or personal injury.

Caution - Always load equipment into a rack from the bottom up so that the rack will not become top-heavy and tip over. Extend your rack's anti-tilt bar to prevent the rack from tipping during equipment installation.

Push the slide-rails as far as possible into the slide-rail assemblies in the rack.

Position the controller so that the rear ends of the mounting brackets are aligned with the slide-rail assemblies that are mounted in the rack.

Insert the mounting brackets into the slide-rails, and then push the controller into the rack until the mounting brackets encounter the slide-rail stops (approximately 30 cm, or 12 inches).

Simultaneously push and hold the green slide-rail release buttons on each mounting bracket while you push the controller into the rack. Continue pushing the controller into the rack until the slide-rail locks (on the front of the mounting brackets) engage the slide-rail assemblies.

You will hear an audible click.

Caution - Verify that the controller is securely mounted in the rack and that the slide-rail locks are engaged with the mounting brackets before you install the optional cable management arm.
