Recovering from a dead system in a SuperNode switch
121 Steps 122 through 136 describe how to restore power from the PDC to Series
I and Series II peripheral module frames. Proceed as follows:
122 Obtain one of the following capacitor charging tools:
•
•
At the PDC
123
At the first empty fuse slot in the PDC, connect the leads of the capacitor
charging tool across the contacts for the fuse holder until the lamp dims. If
you use a charging tool with a fuse holder-style connector, insert the
connector into the slot until the lamp dims.
124 Remove the capacitor charging tool and immediately reinsert the correct fuse
holder into the slot.
125 Repeat steps 123 and 124 for the LCE talk battery, TME talk battery, and PDC
filter fuse holders, removed in step 1. When all fuses are restored to the
PDCs, continue this procedure.
126 Determine if any alarm-indicating fuses are blown.
127 Locate a fuse holder with a blown alarm-indicating fuse.
128 A blown cartridge fuse is in the fuse holder. Remove the fuse holder from
the PDC.
If PDC power
is restored to the PM frames
is not restored to the PM frames
a 100-W, 120-V light bulb in a socket that has pigtail leads
tool number T000655 (CPC number NTA0600512), that has a fuse
holder-style connector instead of pigtail leads for easier insertion
DANGER
Possible equipment damage or extended service interruption
Use the correct fuses. When you return fuses to the PDC,
make sure that the amperage of the fuses match the amperage
marked on the PDC.
Note: The fuse alarm-indicator lamp lights when an alarm indicates a
blown fuse.
If an alarm-indicating fuse
has blown
has not blown
Note: Replace blown fuses in any order.
