SCUN Control board for Huawei MA5680T OLT

SCUN Control board for Huawei MA5680T OLT

SCUN Control board for Huawei MA5680T OLT is a Super Control Unit Board. It is the core of the system control and service switching and aggregation. The H801SCUN board can also function as the management and control core of the integrated network management system (NMS).  [boxads]

It communicates with service boards about the key management and control information through the master/slave serial port and inband GE/10GE channel. In this manner, the H801SCUN board configures, manages, and controls the device, and also implements the simple route protocol functions. The H801SCUN board supports the following functions:

• System control and management unit

• Local and remote maintenance

• Active/standby switchover

• Load sharing (supported in V800R011C00 and later versions)

• Centric management for GE remote extended subracks in FTTB or FTTC scenarios

[adsense]

(supported in V800R012C00 and later versions)

• GE or 10GE channel to the service board

• Environmental monitoring parameters

• Four SFP GE ports for upstream transmission or cascading

The basic working principle of the SCUN board is as follows:

The control module manages the entire board and the service boards, and communicates

with the fan tray through the extended serial port.

• The power module supplies power to other functional modules of the board.

• The clock module provides clock signals for other functional modules of the board.

• The switching module provides the GE port and the 10GE port to switch and aggregate

services at Layer 2 or Layer 3.

– Providing four GE ports for upstream transmission using ports on the front panel

– Providing two GE/10GE ports for each upstream boards in upstream transmission

– Providing 16 GE/10GE ports for implementing GE/10GE switching on each service

board

– Providing two 10GE ports for load sharing with the standby control board(supported in

V800R011C00 and later versions)

  1. I have OLT with card H80MCUD101 and M80MCUD01 but they do not want to work together for some reason. They both have the same software version and when OLT is started from only one card this card works without problems. But if I start OLT with both cards plugged in then one goes into Standby_failed mode and stays like that. I don't know what to do, the only thing that is different is SubType0 which is CPCB for 10G card and CPCA for 1G card. I was unable to find any compatibility informaton on the web so maybe you have run in such problem in the past?

    • MCUD & MCUD1 card not support at a time MA5608T OLT.
      If you use MCUD card you need to keep both slot MCUD.
      If you use MCUD1 card you need to keep both slot MCUD1.
