Communication between a newly installed OptiX OSN 8800 subrack and existing subracks

9

If the newly installed subrack is configured as the slave subrack, connect the ETH port on the EFI board of the subrack to the ETH port on the EFI board of the existing subrack. If the newly installed subrack is configured as the master subrack, use extended ECC or SC2 for communication.

Differences between OptiX OSN 8800 platform subracks and universal platform subracks
OptiX OSN 8800 platform subracks can be installed in N63B and N66B cabinets. Each subrack has 18 service slots and its rated current is 25 A. OptiX OSN 8800 universal platform subracks can be installed in N63B, N66B, and 19-inch cabinets. Each subrack has 16 service slots and its rated current is 60 A, providing stronger power supplies.

Maximum current of an OptiX OSN 8800 T16 subrack
The power consumption of a fully configured OptiX OSN 8800 T16 subrack is 1800 W, the maximum current is 50 A, and the circuit breaker on the PDU is 63 A.

Differences between OSN 8800 platform subracks and universal platform subracks
An OSN 8800 universal platform subrack provides 20 slots. Slots IU1 and IU2 house SCC boards. When only one SCC board is configured, IU2 can house a service board. When an OSN 8800 universal platform subrack functions as a slave subrack, no SCC board can be configured. In this scenario, both IU1 and IU2 can house service boards.

Packet board configuration for slave OptiX OSN 8800 subracks
At present, packet boards can be used only in an independent subrack, but not in the master or slave subrack when subracks are configured in the master-slave mode. When packet boards are configured in an OptiX OSN 8800 T32 subrack, the cross-connect board must be TN52UXCH or TN52UXCM, and the system control board must be TN52SCC in the subrack. When packet boards are configured in an OptiX OSN 8800 T16 subrack, the cross-connect board must be TN16UXCM in the subrack.
