OptiX RTN 600 Routine Maintenance

HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential

Foreword

The OptiX RTN 600 radio transmission system is a

type of short-haul digital microwave transmission

system developed by Huawei. The system supports

a maximum transmission capacity of 1xSTM-1

over one microwave carrier. The OptiX RTN 600

adopts a split-mount structure and a PDH/SDH

integrated microwave transmission platform. It

can be used to provide backhaul in mobile

communication networks or private networks, or

to compose transmission networks together with

optical transmission equipment.

When you are doing maintenance in an equipment room and have no tools at hand,

do as follows:

1. Checking the IF board indicators

2. Checking the service board indicators

3. Testing the orderwire phone

4. Cleaning the air filter (once every two months)

5. Cleaning the equipment room (once every two months)

1. Checking the IF Board Indicators

Checking the SRV Indicator

Checking the BER Indicator

Checking the ODU Indicator

Checking the STAT Indicator


Checking the IF Board Indicators



The SRV indicator deserves the most attention, because it indicates whether

any fault has occurred to the current services.

When the SRV indicator is lit red or yellow, you need to check whether the

services are really affected.

No services are configured.OFF

Minor alarms or remote alarms are generated in the services.ON

Critical alarms or major alarms are generated in the services.ON

The services are normal.ON

SRV


Checking the BER Indicator

The BER indicator indicates the bit error conditions on the current

microwave link.

When bit errors occur on the link, query the actual receiving power of the

ODU by using the Web LCT, to exclude the influence of weather and climate.

Microwave bit errors have not exceeded the threshold.OFF

Microwave bit errors have exceeded the threshold.ON

BER


Checking the ODU Indicator

The ODU indicator indicates whether any fault has occurred to the ODU hardware.

The ODU is faulty.ON

The ODU is operating normally.ONODU



The STAT indicator indicates whether any fault has occurred to the

board hardware.

The board is not started, created or has no power input.OFF

Indicators




Checking the Service Board Indicators

Check the SRV indicator to see if any service error has occurred.

Check the STAT indicator to see if any board hardware error has

occurred.


Testing the Orderwire Phone

Making a call to other site.

The dial tone should be clear after pick up the phone.

The ringing tone should be clear after dial the number.

If remote site answered the call, the voice should be clear without noise.


Cleaning the Air Filter

Clean the air filter once every two months.

Cleaning the air filter is necessary only for the IDU 620 that is configured

with fans.

If installed in a dust-proof outdoor cabinet, the IDU 620 is equipped with

no air filter. There is no need to clean the air filter.


Cleaning the Equipment Room

It is recommend to clean the equipment room once every two

months.

1. Temperature: –5℃ to 45℃.

2. Humidity: 5% to 95%.

3. Disaster protection.

4. Clean the equipment room.

ODU Maintenance

It is recommend to perform the

operations in every half year or

after a fresh gale.

1. Checking the ODU

2. Checking the hybrid coupler

3. Checking the antenna

4. Checking the IF cable

ODU

Antenna

IF cable


Checking the ODU1. Verify that the ODU is within the protection

area of the lightning arrester.

2. Verify that the interface between the ODU

and the antenna is firm and reliable.

3. Verify that the interface between the ODU

and the antenna are properly sealed. Verify

that the sealing is water-proof.

4. Verify that the protection grounding cable

of the ODU is normal.

5. Verify that the ODU is damaged on the

surface.


Checking the Hybrid Coupler

Protection area of the

lightning arrester.

Connections between hybrid

coupler to ODU and antenna.

Water-proof checking for the

interfaces.


Checking the Antenna

Protection area of the lightning arrester.

Connections between antenna to pole.

Antenna radome should be intact.

No water accumulation in antenna.

Position and direction of antenna.


Checking the IF Cable

Check the appearance of the IF cable.The cable should not be bent or twisted.

The cable should not have its copper wire exposed.

The bending radius of the cable should be more than 30 cm.

Check the cable connectors.The cable connector should be reliably connected to the ODU.

There is no water penetration.

Check the cable grounding.The grounding clip should be waterproof.

The grounding cable should be routed from top downwards. The angle between the grounding cable

and the IF cable should not be more than 15 degrees.

Replacing an ODU

Replacing a Board

Replacing an IF Board

Replacing an SCC Board


Replacing an ODU

Power off .Disconnect cables.Uninstall ODU.Install the ODU.

New ODU consistent with the previous one. . Verify the polarization.Lock the four latches in a diagonal order.

Connect back the cables.Carry out the waterproof measures for the IF interface of the ODU.Turn on the ODU-PWR switch on the panel of the IF board.Check status of new ODU by Web LCT.


Plugging Out a Board

Step 1: Loosen the screws on the front panel.

Step 2: Unlock the ejector levers of the board so that the board is disconnected from the backplane.

Step 3: Draw out the board along the guiding rail.


Plugging In a Board

Step 1: Slowly inserting the board along the guiding rail.

Step 2: Lock the ejector levers of the board.

Step 3: Fasten the screws on the front panel.


Replacing an IF BoardWhen the IF board to be replaced is the working board configured with the 1+1 protection, use

the Web LCT or T2000 to perform forced switching for the board. When the service of the

board to be replaced is the working service configured with the SNCP, use the Web LCT or

T2000 to perform forced switching for the service.

Turn off the ODU-PWR switch of the IF board to be replaced. Disconnect the IF cable.

Make sure the version and type of the spare board are consistent with those of the board to be

replaced.

Remove the board.

Insert the spare board. Connect the IF cable.

When the board is working, observe the indicators. The STAT indicator should be lit green.

Turn on the ODU-PWR switch of the IF board.

If the SNCP forced switching was performed for the service, use the Web LCT or T2000 to

cancel it. If the 1+1 protection forced switching of the board was performed, use the Web LCT

or T2000 to cancel it.


Replacing an SCC Board

Remove the SCC board and make sure the

spare SCC board is consistent with it.

Remove the portable memory cards.

Install the portable memory card of the

board to be replaced onto the spare board.

Insert the spare board.

Monitor the indicators, and check the

status of the running SCC board by Web

LCT.
