Install the PA-220 Firewall Using the PAN-PA-220-RACKTRAY

Attach one rack tray bracket to each side of the firewall using two 4-40 x 1/4” screws for each bracket. The brackets are labeled left and right as shown in the illustration.



Attach the power adapter bracket to the back of the firewall using two 4-40 x 1/4” screws.



Install the PA-220 power adapter in the power adapter bracket and secure it with the Velcro strap.

(Optional)

: Install a second power adapter for redundancy.



Slide the firewall (with power adapter bracket) into the rack tray and attach the rack tray brackets to the rack tray using one 4-40 x 1/4” screw for each bracket.



(Optional)

Install a second PA-220 firewall into the right side of the rack tray:

First remove the pre-installed rack tray installation hardware and set aside this hardware for use when you install the second firewall.

Remove one 4-40 x 1/4” screw (located on each side of the front cover) from each rack tray bracket to detach the rack tray installation hardware from the rack tray.
Slide the empty rack tray installation hardware assembly out of the equipment rack tray.
Remove the two screws that secure the front cover to the power adapter bracket.
Remove the two screws from each firewall rack tray bracket and remove the brackets from the front cover. Store the front cover for future use.
Install the rack tray hardware for the second firewall (Step 1 through Step 4) and then install it in the right side of the rack tray.



(Four-post rack installation only)

Install the four-post rack kit (PAN-PA-1RU-RACK4) to provide additional support to the back of the rack tray. First attach one rack-mount rail to each side of the firewall using two #6-32 x 5/16” screws for each rail and torque to 9 in-lbs (you will complete the installation after you install the rack tray in the rack as described in the next step).



With the help of another person, hold the assembled PA-220 firewall rack tray in place in the equipment rack and secure the rack tray brackets to the front rack posts using a #2 Phillips-head screwdriver. Use the appropriate screws (#10-32 x 3/4” or #12-24 x 3/4”) for your rack and torque to 25 in-lbs. Use cage nuts to secure the screws if the rack has square holes.



(Four-post rack installation only)

Slide one back rack-mount bracket into each of the two previously installed rack-mount rails and secure the brackets to the back-rack posts using the appropriate screws for your rack (#10-32 x 3/4” or #12-24 x 1/2”) and torque to 25 in-lbs. Use cage nuts to secure the screws if the rack has square holes.
