2

Select the desired board in the NE Explorer. Choose Configuration > WDM Interface from the navigation tree.
Select By Board/Port(Channel) and choose Channel from the drop-down list.
On the Basic Attributes tab, double-click Laser Status of the desired optical port, and then select Enable or Disable from the drop-down list to change the laser status.

Function of automatically shutting down the client-side laser of a board
If this function is enabled, the client-side laser of a board will be automatically shut down when the WDM side of the board receives no optical signal.

Powering off an E9000
Power off an E9000 as follows: 1. Power off the blades or switch modules in an E9000 chassis using the MM910 Web interface. For details, see http://support.huawei.com/ehedex/pages/DOC1000053358YEF0907R/08/DOC1000053358YEF0907R/08/resources/en/osca/smma_help_r2/it_osca_smma_900020.html. 2. Disconnect the E9000 power cable from the mains supply.

How to shut down the U1980?
1. Before shutting down the U1900 series voice gateway, log in to the device through the CLI and run the save command to save the configuration data. Otherwise, the configuration data will be lost after the device is powered off. Directly turn off the power switch on the U1980 subrack.

Shutting down the firewall
The firewall does not support power-off through the CLI or automatic power-off. Instead, you need to press a button to power it off.

Method used to enable the laser of an OAU or OBU board
Question: All series of OAU and OBU boards can function as wide-spectrum light sources during deployment commissioning. Therefore, you need to learn the commands used to forcibly enable the lasers on the boards. None Answer: 1. The commands used to forcibly enable the lasers on all series of OAU and OBU boards are the same. You can run a command on the Navigator or run a PTP command to enable the lasers. The former method cannot be used in some versions. 2. Command line settings Run the :cfg-set-oaworkmode command to forcibly enable the lasers on the boards. The command format is as follows: :cfg-set-oaworkmode:
  • Bid
  • ,
  • Port
  • ,
  • Path
  • ,
  • Mode
  • ,
  • Password
  • ; Note: a.
  • Mode
  • indicates the board enable status and can be set to gainlock or powerlock, corresponding to the gain-locking mode and power-locking mode respectively. b.
  • Password
  • indicates the verification password used to enable a laser. The default value is dange. c. When a laser is forced to emit light, the output optical power of the optical amplifier board is always 10 dBm. d. This function is supported by 5.08.02.21 or later NE software versions. 3. PTP command settings The command is as follows: :nptp:bid,17,08,c1,1c,1,0,0,0,0; In the preceding command, 17 and 08 are command words, c1 and 1c are check bytes, 1 indicates secure working mode while 0 indicates normal working mode (However, the digit here must be set to 1.), and the last 4 bytes indicate the target optical power parameter (a value 10 times the actual optical power). When the optical power is a negative value, the value is expressed as two's complement. For example, the output optical power is 6 dBm by running the :nptp:bid,17,08,c1,1c,1,0,0,0,3c; command, and the output optical power is �?0 dBm by running the :nptp:bid,17,08,c1,1c,1,ff,ff,ff,9c; command. In the later command, the negative optical power value is expressed as complements.
