Installing MCUD1 in Huawei MA5608

Once on one of the Huawei MA5608 GPON OLT and a regular MCUD card, when the Internet traffic began to reach 900 Mb/s, it was necessary to replace the MCUD with MCUD1 with 10 Gb/s ports.

I note right away that on MCUD1 ports 0 and 1 are 1 Gb/s, ports 2 and 3 are 10 Gb/s.

First, I looked at what boards are installed:

MA5608T(config)#display board 0
-------------------------------------------------------------------------
  SlotID  BoardName  Status          SubType0 SubType1 Online/Offline
-------------------------------------------------------------------------
  0       H805GPBD   Normal
  1       H805GPBD   Normal
  2       H801MCUD   Active_normal   CPCA
  3
  4       H801MPWC   Normal
  5
-------------------------------------------------------------------------

I told the workers to set the new board to hot and turned on the display of alarms in the console:

alarm output all

The board started up for about 3 minutes and then the information was displayed:

MA5608T(config)#

MA5608T(config)#

A little bit later:

MA5608T(config)#

  PARAMETERS :FrameID: 0, SlotID: 3, Position: -1, Load Type: Host program, Load Object: Standby control board

MA5608T(config)#

MA5608T(config)#display data sync state
  Data synchronization is cancelled. The reason is: Software versions of active and standby boards are not consistent
  User configuration data CRC check values of active and standby boards are
inconsistent

MA5608T(config)#

MA5608T(config)#

The board was activated by itself and the command below did not have to be executed (as, for example, for GPON boards):

board confirm 0/3

Automatic synchronization between the boards lasted about 10 minutes, at that moment it was impossible to save the configurations:

display data sync state
 Data synchronization is cancelled. The reason is: Software versions of active and standby boards are not consistent
  User configuration data CRC check values of active and standby boards are
inconsistent

save
  System is loading or backup or duplicating data or rollback or cancelling
rollback, please dispose data later

Later, I checked the status of the boards:

MA5608T(config)#display board 0
-------------------------------------------------------------------------
  SlotID  BoardName  Status          SubType0 SubType1 Online/Offline
-------------------------------------------------------------------------
  0       H805GPBD   Normal
  1       H805GPBD   Normal
  2       H801MCUD   Active_normal   CPCA
  3       H801MCUD1  Standby_normal  CPCB
  4       H801MPWC   Normal
  5
-------------------------------------------------------------------------

Checked the CPU load:

display cpu 0/2
display cpu 0/3

Disabled displaying alarms to the console:

undo alarm output all

Note that you cannot configure VLANs on the ports of the backup card, they will be configured automatically as on the first card when the second card becomes active:

MA5608T(config)#port vlan 208 0/3 2
  Failure: Standby board does not support the operation
 port vlan 208 0/3 2
 port vlan 944 0/3 2

SFP+ 10Gb/s modules used from Step4net 60km DDM 1330nm/1270nm WDM-LC

Note that the link did not up unless you manually specified the speed:

interface mcu 0/3
auto-neg 2 disable
speed 2 10000
duplex 2 full 

Saved the configuration:

MA5608T(config)#save

MA5608T(config)#
  It will take several minutes to save configuration file, please wait...

MA5608T(config)#
  Configuration file had been saved successfully
  Note: The configuration file will take effect after being activated

MA5608T(config)#
  The data is being saved, please wait a moment...

  MA5608T(config)#
  Note: The duplicated configuration file in 0 frame 3 slot takes effect after  being activated 

Since the old MCUD was not relevant, I had to turn off the OLT, switch the optics to MCUD1 and turn on the OLT (they did not take out the active MCUD for hot).
