Reconnect Cables
1. Behind each EPN cabinet power supply, set the circuit breaker to OFF.
NOTE:
Powering down an EPN cabinet without powering down the PPN will
set off alarms. However, these alarms should clear after power is
restored to the EPN.
2. Replace all cables that were labeled and removed.
3. Install the top and bottom rear covers. Be sure the correct rear covers are
installed on the new J58890N Expansion Control Cabinet. Do not use
these rear covers on the port cabinets.
NOTE:
The rear covers for Release 8r 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 a critical reliability Release 8r 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.”
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
Figure 3-17
.
2. Align the mounting holes in the rear ground plate over the bottom screws
in the top cabinet. See
Figure 3-17
.
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.
