Task Set
About This Chapter
Common operation tasks include the operations performed by using the T2000 and the operations performed on site. Learning how to perform these operations helps quickly locate and rectify faults during the equipment maintenance.
8.1 Querying T2000 Operation Logs
To detect the illegal operations, you should check operation logs on the T2000 periodically.
8.2 Querying Current Alarms of a Board
Periodically querying alarms helps detecting and rectifying a fault in time. This section describes the prerequisites and procedures for querying the current alarms of a board by using the T2000.
8.3 Querying the Board Information Report
This section describes how to query the board information report. The board information includes the board type, status, software version and so on.
8.4 Checking the Optical Power
When the receive or transmitted optical power of an optical interface is abnormal, bit errors maybe generated and the optical components may be damaged. This section describes the prerequisites and procedures for querying the board optical power by using the T2000.
8.5 Performing the LSP Ping Test
You can perform the LSP ping test to check the connectivity of the tunnel. This section describes the prerequisites and procedures for performing the LSP ping test by using the T2000.
8.6 Performing the LSP Traceroute Test
You can perform the LSP Traceroute test to locate a fault. This section describes the prerequisites and procedures for performing the LSP Traceroute test by using the T2000.
8.7 Checking Data Consistency Between an NE and the T2000
By performing the data consistency check between an NE and the T2000, you can compare the data configuration on the T2000 with the configuration data on the NE and then obtain a report on the result of the consistency check. Perform the consistency check for all the NEs monthly so that the T2000 can manage the NEs properly.
The NE configuration data on the T2000 may be inconsistent with that on the NE. During maintenance, you need to keep the data consistent on the T2000 and the NE. If the network runs normally and the data on the NE is correct, upload the data from the NE to the T2000.
8.9 Configuring Port Loopback
The port loopback configuration is usually changed for locating equipment faults. By changing the loopback mode, you can locate the fault.
8.10 Performing the MPLS Tunnel Protection Switching
You can perform the MPLS tunnel protection switching on the T2000 to realize the switching of services between different MPLS tunnels.
8.11 Performing the 1+1 Protection Switching for CXPR boards
You can perform the 1+1 protection switching for CXPR boards on the T2000 to realize the switching of status between two CXPR boards.
8.12 Performing IF 1+1 Protection Switch
The IF 1+1 protection switching is an important maintenance operation.
8.13 Querying an IF 1+1 Protection Group
You can know the current status of an 1+1 protection group by querying the IF 1+1 protection group.
8.14 Querying the Working State of AM
You can know the change of the AM mode by querying the working state of AM.
8.15 Setting the State of an ODU Transmitter
the state of an ODU transmitter can be mute or unmute. When the ODU transmitter is in the unmute state, the ODU transmits and receives microwave signals normally. When the ODU transmitter is in the mute state, the ODU transmitter does not work, but the ODU can receives microwave signals.
8.16 Resetting Boards
In the case of resetting boards, the board software is reset. The board reset is classified into warm reset and cold reset. The warm reset does not affect running services. The cold reset, however, usually affects the running services.
8.17 Testing the Transmitted Optical Power of the Optical Interface
If the mean transmitted optical power is excessively high or low, bit errors occur on the equipment. The bit errors affect services and even damage components on the equipment. This section describes how to test the transmitted optical power at optical interfaces of the equipment on site to ensure that the mean transmitted optical power of each optical interface is normal.
8.18 Testing the Receive Optical Power of the Optical Interface
If the receive optical power is excessively high or low, bit errors occur on the equipment. The bit errors affect the services or even damage components on the equipment. This section describes how to test the receive optical power at optical interfaces of the equipment on site to ensure that the receive optical power of each optical interface is normal.
8.19 Replacing Boards on Site
When replacing a board, remove and insert it as required; make sure that the mapping relations between the interfaces and cables are not changed before and after the replacement; observe indicators to determine the running state of the board.
8.20 Powering On the Equipment
This section describes how to connect the power supply to the equipment to ensure that the equipment can be powered on normally.
This section describes how to power off the equipment.
8.22 Querying and Setting the Working Mode of Ethernet Interface
This section describes how to query and set the working mode of Ethernet interface.
8.23 Querying Protection Configuration
This section describes the basic method for querying the protection scheme that is configured in the equipment when a fault or service interruption occurs.
8.24 Inspecting and Cleaning the Optical Fiber Connectors
Cleaning optical components is to remove dust or other dirt to avoid performance degradation of optical transmission systems. Inspecting and cleaning fiber connectors used in fiber optic connections are introduced here.
8.1 Querying T2000 Operation Logs
To detect the illegal operations, you should check operation logs on the T2000 periodically.
