STEP 6 |
(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).
STEP 7 | 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.
