7
The curvature radius of an optical fiber should be 20 times greater than the diameter.
In general, it should be greater than 40 mm.

8
Labels on both ends of the signal cable should be correct, distinct, and neat.
View.
9
Power cables and ground cables are connected correctly and reliably.
View.
10
The cabling of the power cable and ground cable should comply with engineering design documents
to benefit later capacity expansion.

Inspection before powering on device
No.
Item
Method
1
Test the DC power with a multi-meter. Ensure that the voltage is from -38.4 to -57.6 VDC.
Use a tester.
2
The power capacity should be able to support the ISCOM6820-GP runing at the maximum power
consumption.
View.
3
Test the ground resistance of the power cable and ground terminal. The value should not be
greater than 1 Ω.
Use a tester.
Power-on inspection
No.
Item
Method
1
After the device is powered on, LEDs of the power module and service cards should be in
correct status. If an interface is connected properly with a cable, its LNK/ACT LED should be
Green. If an interface is not connected with a cable, its LNK/ACT LED should be Off.
View.
2
The fan module should work normally with LEDs in correct status. There should be air flow
around the device.
View.
3
Test the optical power of an installed SFP with an optical power meter. The value displayed on
the meter is P1. Compare the P1 to specifications of the SFP optical module to verify whether
the optical module works properly.
Use a tester.
4
Connect the optical fiber at the side of the ODF which is connected to the device with an optical
power meter. The value displayed on the meter is P2. If the difference between P2 and P1 is
smaller than 1 dB, it indicates that the fiber is correctly connected.
Use a tester.
