The SWUA1 consists of an exchange carrier board, a GE daughter board, and a TDM daughter board.

It provides the network switching, device management, and configuration restoration functions.

The SWUA1sare inserted in slots 6 and 7 in the subrack. They exchange network data
with other boards (including the SMMs) through the backplane, and
provide service and cascading interfaces through the SWI.


  • Network switching


    The SWUA1 provides the switching functions for the Base plane and the
    GE switching functions for the Fabric plane. The two planes are
    independent of each other.


    The SWUA1 provides the following network switching
    functions:


    • Layer-2 full line speed switching supported by all the interfaces
    • Interface bundling
    • IEEE802.3x auto-sensing and flow control supported by all the Ethernet interfaces
    • Multiple gigabit interface standards (10/100/1000M Base-T and 1000M Base-BX)
    • Address learning
    • 802.1Q virtual local area network (VLAN)
    • 802.1D spanning tree and multiple spanning tree
    • Device cascading
    • Priority queuing on the output port
    • 9 kB Jumbo frame

  • TDM narrowband switching


    The SWUA1 configured with the TDM daughter board can implement TDM narrowband switching.


    The TDM daughter board collects and distributes the TDM service data
    within the subrack and between subracks. Working
    in conjunction with the narrowband service boards in other slots, the
    TDM daughter board receives and switches the TDM service data. In
    addition, the TDM daughter board, together with the SWI, implements the
    software phase-locking algorithm for the
    clock.


  • Device management


    The SWUA1 provides the following management functions:


    • Providing an independent baseboard management controller (BMC)
      module and a redundancy intelligent platform management bus (IPMB). The
      BMC reports the hardware status and alarms of the SWU to the SMM so that
      the SMM can manage the SWU.
    • Managing the information about the field replaceable units (FRUs), sensor data records (SDRs), and system event logs (SELs)

    • The
      BMC is the core of the Intelligent Platform Management Interface (IPMI)
      standard. It collects, processes, and stores the signals of all the
      sensors, and monitors the operating status of each component.
    • FRUs
      refer to the units that can be replaced on site, such as the fan box,
      board, daughter board, and PEM. FRU information refers to the
      information that is stored in the non-volatile memories of the FRU, such
      as the manufacturing information.
    • SDRs refer to the data
      recorded by the sensors, such as the temperature and voltage. You can
      learn about the status of the system through the SDRs.
    • SELs refer to the system event logs, such as the reset of an FRU or generation of an overtemperature alarm.


  • Configuration restoration


    Configuration restoration enables you to apply the configuration data
    of the original SWU to the new SWU through the SMM during the
    replacement of the SWU. Configuration restoration involves the following
    functions:


    • Providing an option for selecting the configuration file to be loaded during startup.


      During the startup of the SWUA1, if the configuration file of the
      SWUA1 is available on the SMM but is different from that on the SWUA1,
      the SWUA1 provides
      a menu for you to select the configuration file to be loaded.


      You can load either the configuration file downloaded from the SMM or
      the configuration file stored in the SWUA1. If you do not perform any
      operation within five seconds, the SWUA1
      automatically downloads the configuration file from the SMM, and then
      starts the loading process.


    • Backing up the initial configuration file of the SWUA1 automatically.


      After you download the configuration file from the SMM and start the
      loading process, the SWUA1 automatically backs up the initial
      configuration file by adding the extension
      .bak to the file.


    • Backing up the current configuration file of the SWUA1 synchronously.


      Every five minutes, the SWUA1 checks whether the configuration file
      on the SWUA1 is the same as that on the SMM. If the configuration file
      is different, and the size
      of the configuration file on the SWUA1 is smaller than or equal to 32 KB
      (but more than zero byte), the SWUA1 synchronizes the current
      configuration file of the SWU0 to the SMM. In other cases, the
      configuration files on the SWUA1 and the SMM remain
      unchanged.


      If the configuration data has been saved by running the save
      command, and the size of the configuration file on the SWUA1 is smaller
      than or equal to 32 KB (but more than zero byte), the SWUA1
      synchronizes the current
      configuration file of the SWU0 to the SMM
