Checking the Connection and Layout of Wires and Cables
No.
Items to Check
Means
1
The specifications, routes, cross-sectional areas, and positions of the cables arranged are
compliant with the construction plan drawing. The cables are arranged in good order,
without damage to their sheath.
Visual
inspection
2
The cable plugs are clean and intact, and the plugs made onsite are up to standard. The
connectors are correctly and firmly connected.
Visual
inspection
3
When cables must be arranged along the upper part of the cabinet, the distance between
them and the ventilation hole on the cabinet top should be no less than 10 cm. If the
distance between the cabling rack and the cabinet is larger than 0.8 m, installers should set
up a cabling ladder.

Layout of fiber pigtails:
Fiber pigtails are not arranged too closely to each other or intertwined at the turning
points. The paired fiber pigtails are bound after being arranged in order. Do not bind
with too much force and leave pressure marks on fiber pigtails.
Fiber pigtails can move forward or backward freely in fiber fasteners but cannot bend in
right angle.
After fiber pigtails are arranged, do not put any cables or other objects on them.
Visual
inspection
When the connection and layout of cables and wires are completed, installers should conduct the
connectivity test and ensure that signals are transmitted normally.
15.2
Checking Before Power-on
The AN6000-15 uses -48 V DC power supply with an acceptable voltage range from -40 V to -57 V.
Before powering on the equipment, installers should:
1. Confirm that the cabinet power cables are correctly connected with the external power supply
equipment.
2. Confirm that all the wires and cables are connected correctly.
3. Place all the power switches on the PDP in the OFF position.
4. Disconnect all the cards inside the subrack but leave them on their slots.
5. Disconnect the fan unit inside the subrack but leave it on its slot
.

Power-on Test
The power-off procedures for the AN6000-15 are reverse to those of power-on.
Instruction
1. Measure the voltage between the -48 V and the 0 V connectors in the external power input area of the
PDP. The normal value should be between -40 V and -57 V.
2. Place all the output branch switches on the PDP in the ON position.
3. Confirm that the subrack has no abnormal sound or smell.
4. Insert the fan unit, making sure it starts running normally and air movement begins around it.
5. Insert cards into the subrack in sequence and the cards will be electrified normally in two or three
minutes. Make sure the indicator LEDs of all these cards indicate normal working status.
6. Check whether the active-standby power supply protection works.
①
Check whether the ACT indicator LED on the card is illuminated, which indicates
normal power-on.
②
Check whether the ALM indicator LED on the card is OFF, which indicates no alarm.
