C. INSTALLATION AND TEST
7. Unpacking
7.1
Upon receipt of the equipment, proceed as follows:
1
Unpack each container and visually inspect it for signs of damage. If the equipment has been
damaged in transit, immediately report the extent of damage to the transportation company and
to PairGain. Order replacement equipment if necessary.
2
Check the contents versus the packing list to ensure complete and accurate shipment. If the
shipment is short or irregular, contact PairGain as described in Section 11. If you must store the
equipment for a prolonged period, store the equipment in its original container.
8. Installation
Observe normal electrostatic discharge precautions when handling electronic
equipment. Do not hold electronic plugs by their edge. Do not touch
components or circuitry.
An FPI-729 List 1 PGTC Interface Unit or an FAU-728 List 2 Alarm Unit must be
installed at all times when ISDN channel units are installed. These units
provide the composite clock reference source for the ISDN channel units and
are required for normal operation of the ISDN channel units. Removing the FPI-
729 List 1 or FAU-728 List 2 during an ISDN call terminates the call.
8.1
Install a FLL-712 COT line unit and verify operation as follows:
1
Insert the FLL-712 COT line unit into the COT shelf and verify:
•
all LEDs on the Line Card turn on for about one-half second, then turn off
•
PWR and FAULT LEDs turn on
•
after ten seconds, the COT starts its power management routine and the PWR LED flashes
If line powering fails, wait one minute before attempting to reinsert the FLL-712.
If line powering succeeds, HDSL communications begins synchronizing and
LOOP 1 SYNC and LOOP 2 SYNC flash.
2
Verify the following front panel indications after the system powers up and establishes HDSL
synchronized communications, and when no calls are in progress:
•
POWER is on
•
LOOP 1 SYNC is on
•
LOOP 1 MARGIN is off
•
LOOP 2 SYNC is on
•
LOOP 2 MARGIN is off
•
TEST is off
•
FAULT is off
