2.5.1 Types of Cable
In a building block configuration, use the following cables for connection:
  1. Crossbar cable
    Use either crossbar cables (optical) or crossbar cables (electrical) exclusively for the connections of the XBU mounted in each SPARC M12-2S. Use only crossbar cables (optical) for the connections between a crossbar box and the XBU in the SPARC M12-2S. Cables simply described as "crossbar cables" in this manual refer to both crossbar cables (optical) and crossbar cables (electrical).
  2. XSCF BB control cable
    This cable is used to connect XSCFs mounted in different SPARC M12-2S units or to connect a crossbar box and the XSCF of a SPARC M12-2S unit.
  3. XSCF DUAL control cable
    This cable is used to connect the master XSCF to a standby XSCF to duplicate the XSCF.
Each cable has an attached tag used for maintenance notes and management.
