Checking The Installation - Huawei PTN Series Quick Installation Manual

Checking the Installation

No.
1 The chassis should be installed firmly in the position specified in the engineering design document. Make
sure that the chassis does not contact the front door and the cables are not pressed by the front door,
when the front door is closed.
2 Each chassis component should be free of paint drop, damage, or stain. Otherwise, re-paint or clean the
component.
3 The air intake and exhaust vents of the device cannot be blocked to ensure proper heat dissipation.
4 When a board is inserted into the chassis, the screws on the front panel of the board should be tightened.
5 Empty slots in the chassis should be covered with filler panels.
6 The routing of the cables should conform to the engineering design document and should facilitate
maintenance and expansion in the future.
Cable routing has no effect on the removal of boards.
7
8 The cables should be free of damage, break, or joint in between.
9 Each core of the cables should be tested for connectivity.
10 The cables should be bundled closely with proper force. The spacing between the cable ties should be
even. After the cable ties are fixed, the remaining part should be trimmed with no burrs.
11 The signal cables should be routed correctly in the cabinet.
12 The cables outside the cabinet should be routed as follows:
•The cables should be placed tidily and be free of crossover.
•In the case of a cable ladder, the cables should be bound onto the ladder beam tidily. If the cable tray is
0.8 m or more higher than the cabinet top, a cable ladder should be available on the cabinet top to support
the cables and to ease stress.
13 The cable turns should be smooth and have a big bending radius.
14 The cable labels should be filled in correctly and stuck reliably. They should be aligned and face to the
same direction. The labels need to be stuck two centimeters away from the connectors.
15 The power cable and ground cable should be routed separately from the signal cables.
16 The unused cable connectors should be protected. For example, the connectors should have protective
caps installed.
17 The protective tube for the fiber jumpers should be led into the cabinet by about 10 cm inside and bound
tightly.
18 The cuts of the protective tube for the fiber jumpers should be smooth. Otherwise, they should be
wrapped by an insulation tape.
19 The fiber jumpers should not be bound over-tightly, and can be moved freely in the cable tie.
20 The connecting points of the fiber jumpers should be free of dust. The unused fiber connectors and optical
interfaces should be protected by protective caps or plugs.
