Install the EPN
3. Install the top and bottom rear covers. Be sure the correct rear covers are
installed on the Expansion Control Cabinet. Do not use these rear covers
on the port cabinets.
Power Up the EPN Cabinet
1. Behind each EPN cabinet power supply, set the circuit breaker to ON. After
about 40 seconds, EPN power and PPN/EPN communications return.
2. After power returns to the EPN and all trouble is cleared, verify the
EMERGENCY TRANSFER CONTROL switch is set to AUTO. This
restores the system to the normal mode.
Install Rear Ground Plates (Systems with
Earthquake Protection)
1. Loosen the 4 screws at the bottom of the top cabinet and at the top of the
cabinet underneath the top cabinet. See
2. Align the mounting holes in the rear ground plate over the bottom screws in
the top cabinet. See
3. Align the mounting holes in the ground plate with the 4 holes at the top of
the cabinet below the top cabinet. Slide the mounting plate down to seat on
the screws.
4. Check all TDM bus cables and the ICC to be sure they are not pinched by
the plates.
5. Repeat Steps 1-3 until the rear ground plates are installed between all
stacked cabinets.
6. Do not tighten the screws yet.

NOTE:
The rear covers for control carriers may need 2 detents (1 for the
TDM/LAN cable and another for the ICC cables). If the Release 5/6si
was upgraded to critical reliability and the EPN was originally an
R1V3, replace the lower rear cover of port cabinet "B" with a new
cover (846307817) so the ICC cables and the new ground plate can
be installed between cabinets A and B.
