Number of slave subracks supported by an NE

4

The number of subracks supported by an NE depends on the types of subracks and system control boards.

OSN 9800 does not support optical-layer slave subracks.

Maximum number of slave subracks that the TN11SCC board on OSN 6800 supports during capacity expansion
No more than eight optical subracks, four electrical subracks, or eight optical and electrical subracks totally (no more than four electrical subracks). One OSN 8800 T32 subrack is equivalent to two OSN 6800 subracks. 1. The subrack quantity refers to the number of equivalent subracks. One OSN 6800 subrack is an equivalent subrack. 2. An electrical subrack is used to house cross-connect boards, OTU boards, tributary boards, line boards, and protection boards. For example, universal platform subracks and platform subracks are regarded as electrical subracks if they house only OTU boards (not in regeneration mode). Optical-electrical subracks are regarded as electrical subracks. 3. An optical subrack is used to house OADM boards, multiplexer boards, demultiplexer boards, optical amplifier boards, OSC boards, optical spectrum analyzer boards, regeneration boards, OLP boards (used in optical line protection), and OTU boards (in regeneration mode). For example, a subrack housing only protection boards is regarded as an optical subrack.

Number of equivalent NEs that one OSN 8800 platform subrack is equal to
One OSN 8800 platform subrack is equal to one equivalent subrack.

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.

Changing OSN 1800 independent subracks to master/slave subracks
Associating a logical master subrack with a physical subrack: After creating an NE on the NMS and uploading NE data, associate the logical master subrack with a physical subrack. Adding logical slave subracks: Based on the ID information of slave subracks in the actual networking, add logical slave subracks. Associating logical slave subracks with physical slave subracks: Based on the networking status, associate logical slave subracks with master slave subracks to establish the mapping between the subracks.
