Maintenance and Troubleshooting
Reinstalling the Power Supply Module (Metal Carrier)
WARNING:
Do not install the power supply unless the carrier is connected to an approved ground.
I
Before touching leads, connectors, pins, and other components, use a properly grounded
I
wrist strap, to prevent damage from electrostatic discharge (ESD). The wrist strap can be
clipped to the ground screw or plugged into the hole next to the ground screw.
Do not attach any cables or power cords to the power supply until it is installed in the
I
carrier.
Do not power up the control unit until all of the modules and power equipment are
I
installed. Failure to comply with this procedure can result in shock hazard and/or damage
to the equipment.
Follow these steps to install the power supply module in the metal carrier:
1. Align the circuit board guides inside the carrier, and slide the power supply module into the
slot.
2. Make sure the connector on the back of the module mates properly with the connector on the
carrier.
3. Secure the module with two screws, one on top and one on the bottom.
The power supply may make a ticking sound when plugged in but not turned on. This
is normal operation.
4. Power up the system.
CAUTION:
Follow the procedure below to power up the system only if the system is completely
I
installed. Failure to comply with this procedure can result in shock hazard or damage to
the equipment.
Do not power up the system unless all carriers are connected to an approved ground.
I
a. Turn on the power switch for each expansion carrier: start with the power supply in the
rightmost carrier.
The green power lights on each expansion carrier power supply should turn on.
b. Turn on the power switch on the basic carrier power supply.
The dot on the one-character display LED flashes.
I
The green light on the power supply turns on.
I
The red light on the processor should turn on for 15 to 45 seconds and then turn off.
I
All indicators on the 100D, 100R, and 400 E&M line/trunk modules (if present) turn on
I
and then off. They remain off when the modules are idle.
5. If any of these conditions are not met, continue troubleshooting the system.
