Some tasks to finish the NE commissioning, in preparation for network commissioning



2.1 Checking Hardware Purpose Describes how to check the equipment hardware before the

equipment is powered on. To ensure there is no any fault or damage about hardware before commissioning.

Tools/Instruments None

User authority level None

Prerequisites The hardware installation has been finished.

Required/As needed Required

Check hardware before the cabinet is powered on. This section gives the criteria for several important testing items. For details, see OptiX OSN 9500 Intelligent Optical Switching System Installation Guide.

2.1.1 Checking Cabinets

Ensure:

Installation of cabinets must comply with the requirements of the construction drawing.

That, if there are multiple cabinets, they must be aligned with one another. Each cabinet must stand horizontal and stable.

The outlet on the top of the cabinet is right under the cabling trough in the equipment room.

The bolts for fixing the support on the ground and the cabinet on the support are tightened, and spring washers and flat washers are installed in correct order.

The orderwire phone and electrostatic discharge (ESD) wrist strap are in place and in right use.

Cabinets are clear of waste.

2.1.2 Checking Subracks

Ensure:

The subracks are correctly grounded. The vacant slots are clean and there is no small bolt or broken cable tie in the

subrack. The vacant slots are installed with blank panels. The cabling trough is not damaged and is connected with the subrack fixedly.


Commissioning Guide


2.1.3 Checking Resistance Between Power Cable Posts

The OptiX OSN 9500 distributes the power through the direct current (DC) power distribution unit at the top of the cabinet. For details, see OptiX OSN 9500 Intelligent Optical Switching System Hardware Description.

Step Action

1 Check whether the cabinet is connected to the power supply equipment. If so, push the switch on the power supply equipment to OFF.

2 On the power distribution unit, push power switches for the subrack to OFF .

3 Measure the resistance between NEG1 (–) of INPUT1 and RTN1 (+) of INPUT1. The value should be ∞.


5 Measure the resistance between NEG1 (–) of INPUT1 and the protection grounding post ( ). The value should be ∞.



8 Measure the resistance between NEG2 (–) of INPUT1 and the protection grounding post ( ). The value should be ∞.

9 Measure the resistance of INPUT2 refer to step 3–step 8.

10 On the power distribution unit, push power switches for the subrack to ON.

11 Measure the resistance between NEG1 (–) of INPUT1 and RTN1 (+) of INPUT1. The value should be more than 20 kilohms.


13 Measure the resistance between NEG1 (–) of INPUT1 and the protection grounding post ( ). The value should be more than 20 kilohms.



16 Measure the resistance between NEG2 (–) of INPUT1 and the protection grounding post ( ). The value should be more than 20 kilohms.

17 Measure the resistance of INPUT2 refer to step 11–step 16.

18 After the test, turn off power switches for the subrack on the power distribution unit.



Caution The testing method must be correct. The positive pole of the ohmmeter should be connected to RTN(+) , while the negative pole to NEG (–). If poles of the ohmmeter are connected reversely, the obtained value will be smaller than the actual value, usually less than 10 kilohms. When the power switch on the subrack is pushed to ON position, if the resistance between cabling posts is less than 20 ohms, it indicates that a short circuit occurs between the –48 V working power and the working ground. Resolve the fault before proceeding to the power-on test.

2.1.4 Checking Cable Connection

This section describes several important cabling rules. For details, see Appendix D "Engineering Labels for Cables" of OptiX OSN 9500 Intelligent Optical Switching System Installation Guide.

All cables are bundled with evenly spaced bundling points and appropriate tightness. The cable ties are cut off neatly. All cable ties face the same direction.

All cables are arranged neatly. There is no crossover or bend. A trough is used for cabling outside the cabinet. There should be no cables

protruding from the trough. If a cabling ladder is used, the cables must be secured neatly on its beam in a

rectangular shape (or in a circular shape when the cables are single-cored). At the turning point, big bend radius (more than 6 cm) is required. There is no

bundling at the turning point. Power cables and grounding cables are connected correctly. The diameter of the power cables and grounding cables meets the requirements

of power distribution. The power cables and grounding cables outside the cabinet are arranged

separately from the signal cables, with a distance of more than 3 cm. The power cables and grounding cables bend smoothly. There is no joint at any point of the power cables and grounding cables.

2.1.5 Checking Board Appearance

2 Connect the fibre jumper on the IN optical interface at the local station to the input port of the optical power meter, as shown in Figure 2-4.

3 When the received optical power keeps stable, read the value. The value is the actual received optical power of the line board.

4 Check the optical power measured. If the value is smaller than the sensitivity of the line board, go to step 5. If the value is larger than the overloaded index of the line board, go to step 6. For indexes of different optical interface boards, see OptiX OSN 9500 Intelligent Optical Switching System System Description. Note: The received optical power should have some surplus. It is recommended the received optical power is 3 dB larger than the sensitivity index and 5 dB less than overloaded index at least.

5 Check the fibre line. After resolving the fault, return to step 1 to test the received optical power again. Note: If the received optical power is too small, check the cable length, the optical fibre connector, and connection of the flange at the ODF side. If the fibre connector is dirty, clean it. For too high attenuation, rebuild the line. If the optical cable is too long, replace the board with a new one with higher launched optical power or add more optical signal amplifier boards.

6 Add another attenuator at the ODF side. After resolving the fault, go back to step 1 to test the received optical power again.

7 If the test value still cannot meet the requirement, check the fibre connection and the boards at the remote station. If there is any fault, resolve the fault. Then test again from step 1.

2.7 Testing On/Off of All Electrical Interfaces and Cabling Error-free

Purpose Describes how to check the connection from the equipment to DDF. To ensure each connection is right.

Tools/Instruments T2000, BER tester

User authority level T2000 user with the authority of "NE and network operator" or above

Prerequisites Before this test, route cables to the appointed DDF according to the design document.


After connecting cables with the OptiX equipment and DDF, perform electrical interface on/off and cabling error-free tests.

Step Action

1 Set the first 155 Mbit/s port to Outloop on the T2000. Connect the BER tester to the first 155 Mbit/s port on the DDF. The T_ALOS alarm should disappear.

2 Cancel Outloop on the T2000. In this case, the BER tester gives an alarm, indicating the BER tester is connected to the first 155 Mbit/s port and the receiving and transmitting cables are connected correctly.

3 Similarly, check the receiving and transmitting cables of each 155 Mbit/s port in order. Test in both the ON and OFF states.

4 Ensure the on/off function of all electrical interfaces is normal (reliable cable connection, no short circuit or blocking).
