Removing the Backplane Knockout

The PNS can be installed in slot 1 or slot 2 of a 7-, 12-, or 16-slot RX3i Universal Backplane
(IC695CHS007, CHS012 or CHS016), or in slot 6 of a 7-slot RX3i Universal Backplane. It may
not be in the same rack as an RX3i CPU module. For details, refer to the PACSystems RX3i
System Manual, GFK-2314.
For revision Axxx PNS modules, the rear of the PNS module has an exposed heat sink and
backplane connector. Before inserting the module into the backplane, remove the plastic
knockout in the slot into which the module will be placed. This is not required for revision
Bxxx or later modules. The installation slot must match the slot selected for the module in
the PAC Machine Edition hardware configuration.

Installation
RX3i rack power must be turned off. The PNS does not support insertion/removal
while power is applied to the rack.
Holding the module firmly, align the module with the correct slot and connector.
Engage the module's rear pivot hook in the notch on the top of the backplane (1).
Swing the module down (2) until the module's connector engages the backplane's
backplane connector.
Visually inspect the module to be sure it is properly seated.
Secure the bottom of the module to the backplane using the machine screws
provided with the module (3).
For revision -Axxx modules, tighten the heat sink screw on the front of the module
in the threaded hole in the back plate to 6 in-lbs (0.68 Nm), using a flat-tip
screwdriver.
