Prerequisites:
Make sure you have purchased the Active Fail-Open switch chassis.
Identify the rack in which you plan to install the fail-open chassis.
If you are using a physical Sensor, make sure that you can physically connect the chassis with the monitoring ports.
You can install up to four fail-open switches in a single chassis.
Note
You can install an active fail-open switch module in the chassis on the fly while the chassis is powered on in the rack.
Steps:
Install the ears of the chassis.

Slide the switch into one of the openings in the chassis, until the face plate of the switch rests against the chassis.
Secure the switch to the chassis by inserting screws provided through the holes on the fail-open switch face plate and into the panel.
Note
If you are attempting to install a switch while the chassis is powered on, you must wait for 4 seconds after inserting the switch and fastening its screws.
Place the 1U chassis against the front of a standard 19-inch rack.
Secure the chassis by inserting screws through holes on the ears of the chassis (refer to the Prerequisites instructions for this section).
(Optional) Install up to three additional switches by following these steps:
Remove the screws holding each of the removable blank plates from the front of the chassis.
Follow steps 1 and 2 of this procedure for installing a switch in the chassis for additional fail-open switches.
Result: The fail-open switch is ready to be connected to a Sensor.
