Checking the Installation
1 Installation Checklist
Double check that these items have been properly performed.
No
.
The cabinet is positioned in the proper place as prescribed by the engineering
1
design.
The cabinet components must be installed correctly, without damaged or loosen
2
parts. There should be no fingerprints, scratch marks or other stains on the cabinet.
3
Cable holes at the top and the bottom of the cabinet are securely sealed.
4
Cables are routed according to the engineering design.
Cables are not damaged or broken, and there are not any joints on the cable. The
5
cable connectors are connected correctly and securely.
Cables are laid horizontally or vertically without crossing, and there is moderate
6
bundling at the bending radius of the fiber patch cords. Labels at both ends of the
cable and fiber are marked correctly, clearly, and neatly.
The fibers routed outside the cabinet are protected in a corrugated pipe, and are
7
protected from being pulled out by other cables or objects.
The bending radius of the fiber patch cords is not less than 30 mm. There are not
8
any sharp components along the routing path for the fibers.
Fibers are placed in order and are properly bound with optical binders. There are
9
not any sharp edges.
2 Checking the Equipment Prior to Powering on
a
Powering on the Cabinet
CAUTION
Check whether a fixed optical attenuator was added before powering on the subrack. Refer to configuration
rules for attenuators prior to proceeding.
Turn off the switch to the power supply, and then use an ohmmeter to measure the resistance between NEG (-),
RTN(+) and PGND.
Switch
Turn all the power switches on the
power distribution box to OFF
Turn all the power switches on the
power distribution box to ON
CAUTION
Turn off all power switches on the power distribution box after the test.
