Checking the Installation
No.
What to Check For
1
The chassis is installed securely in the position specified in the engineering design documents. If the cabinet
door is closed, the door should not press against the chassis or any cables.
2
Chassis components have no paint spatters, damage, or stains.
Re-paint or clean components, as required.
3
Cable routes comply with the engineering design documents and facilitate maintenance and expansion.
4
Cables are not damaged, broken, or spliced together.
5
Cable cores have been tested for connectivity.
6
Cables are properly bound. Cable ties are installed at equal intervals and face in the same direction. Cable ties
have been trimmed after tying and there are no rough edges.
7
Signal cables are routed correctly in the cabinet.
8
Cables outside the cabinet are routed as follows:
•Cables are run neatly and are not cross -connected.
•If a cable ladder is used, the cables are bound onto the ladder beam neatly. If the cable tray extends 0.8 m or
more above the cabinet top, a cable ladder is installed to support the cables and ease stress.
9
Cable turns are smooth and have a large bending radius.
10
Cable labels are filled in correctly, attached securely, and are aligned to face in the same direction. Preferably,
labels are attached at least 2 cm away from connectors.
11
The power cable and ground cable are routed separately from signal cables.
12
Unused cable connectors are protected. For example, protective caps are installed on unused connectors.
13
Cable connectors are inserted securely and the screws on the connectors are tightened.
14
Corrugated pipes for fiber jumpers are inserted 10 cm into the cabinet and bound securely.
15
The cuts for jumpers on corrugated pipes are either smooth or have been wrapped with insulation tape.
16
Jumpers are bound gently to ensure free move in cable ties.
17
Connecting points of fiber jumpers are clean. Protective caps (plugs) are installed on unused fiber connectors
and optical ports.
19
The positive terminals of the power supply device connected to the RTN 905 are properly grounded.
20
The ground point on the column of the cabinet or the indoor ground bar is properly grounded.
