Supported ports of the CCUB board


The CCUB control board supports the following 3 types of ports:

  • Panel ports (on the backplane): CONSOLE (connecting to the local maintenance serial cable), ESC (connecting to the network cable), ETH (connecting to the network cable), ALARM (connecting to the environment monitoring cable), and GE0 (connecting to optical fibers).

  • Upstream ports (on a daughter board): When H831GP1A or H831EP1A is configured, GE0 (SFP) and PON (SFF) ports are available for connecting to optical fibers. When the H831GE1A daughter board is configured, GE0 (SFP) and GE1 (SFP) ports are available for connecting to optical fibers.

  • Cascade port: Only 1 GE (optical or electric) cascade port is supported. GE (optical or electrical) indicates alternative of the optical port or electrical port for GE0 optical port provided by the daughter board, and duplexes with GE0 electrical port on the front panel.
