Prerequisite:

Depending on whether you can physically connect the fail-open switch to a computer using an RS232 cable, you might consider swapping this step with configuring fail-open switch parameters.

These steps explain the procedure to install fail-open switch model 1.

  1. Slide the switch into the opening in the center of the rack-mount panel, until the faceplate of the switch rests against the panel.

  2. Secure the switch to the rack-mount panel by inserting screws through the holes on the switch faceplate and into the panel.

  3. Install the panel and fail-open switch on the rack.

    1. Place the 1U panel against the front of a standard 19-inch rack.

    2. Secure the rack-mount panel by inserting the screws (included with the rack-mount panel) through the holes on the front of the panel and the sides of the rack.

  4. Additional fail-open switches can be installed without removing the rack-mount panel from the rack. To install up to two additional switches:

    1. Remove the screws holding one of the removable blank plates from the front of the panel.

    2. Follow the procedure for installing a switch in the rack-mount panel for the additional fail-open switch.
