How Do I Query the Serial Number of a Device?

How Do I Query the Serial Number of a Device?

To query the serial number of a device, view the serial number label attached to the device or run a display command.

  • Viewing the Serial Number Label Attached to the Device

    Serial number labels are attached to CE series switches. You can view these labels to obtain the serial numbers of CE switches. The serial number label of CE12800 and CE12800E switches is attached to the rear of the chassis, as shown in Figure 22-129. The serial number label of a CE8800, CE7800, CE6800, and CE5800 switch is drawable and attached to the front of the chassis on the power supply side, as shown in Figure 22-130.

  • Running a display Command

    • Run the display device elabel command to view the serial number of the device. This command applies to all the versions of CE12800 and CE12800E and CE8800, CE7800, CE6800, and CE5800 series switches.

      In the following example, the display device elabel command is executed on a CE12800 switch.
      <HUAWEI> display device elabel
      The command is being executed. Please wait...
      
      [BackPlane_1]
      
      /$[ArchivesInfo Version]
      /$ArchivesInfoVersion=3.0
      
      
      [Board Properties]
      BoardType=CE12804-AC
      BarCode=2102113774P0E4000003
      Item=02113774
      ... ...
      
      BarCode in BackPlane_1 in the command output indicates the serial number.

      The display device elabel command can also display serial numbers of components on the device, including LPUs, power modules, fan modules, and optical modules.

    • Run the display sn [ all ] command to view the serial number of the device. This command applies to V100R005C00 and later versions of CE12800 and CE12800E and CE8800, CE7800, CE6800, and CE5800 series switches.

      In the following example, the display sn [ all ] command is executed on a CE12800 switch.
      <HUAWEI> display sn
      Chassis 1:
      Equipment SN(ESN): 2102113774P0E4000003
      License ESN: 2102113774P0E4000003
      ... ...
      
      This command can also display the serial numbers of fan modules, power modules, and optical modules of the device.
