OSN 9800 U32 Standard overview
Intended for 100G and beyond 100G optical networks, the 9800 U32 Standard subrack is a next-generation large-capacity OTN product that integrates ASON, OTN, and packet functions. It is applicable to various networks, including super-backbone, backbone, and metro networks.
OSN 9800 U32 Standard subrack areas and slots
Boards need to be installed in the designated slots in the subrack. 9800 U32 subracks are classified into two types, namely 9800 U32 Standard and 9800 U32 Enhanced.
Descriptions of the areas and slots in the OptiX OSN 9800 U32 Standard subrack
| Area | Composition | Slot | Function |
| Power and interface area | 1 EFI (TNV1EFI/TNV2EFI) board and 10 PIU boards | PIU: IU100-IU104, IU106-IU110 | The PIU boards are in mutual backup. Therefore, the failure of any power input to the equipment does not affect the normal operation of the equipment. NOTE: The PIU boards on the left and right sides of the EFI board are in mutual backup, for example, the PIU boards in slots IU100 and IU106, the PIU boards in slots IU101 and IU107, and so on. The EFI board provides maintenance and management interfaces. |
| EFI: IU105 | |||
| Fan areas | 4 fan(TNV1FAN) tray assemblies | Lower portion: IU90, IU91 | The fan tray assemblies are used to ventilate the equipment. |
| Upper portion: IU92, IU93 | |||
| Fiber-routing areas | 2 fiber troughs | N/A | Fiber patch cords connecting to boards are routed to the left or right side of the subrack through the upper- and lower-side fiber troughs. |
| Service board areas | 32 service boards | Lower portion: IU1-IU16 | Service boards need to be configured based on the service plan and all of them are installed in the two service board areas. NOTE: Service boards installed in slots IU1-IU16 have their ejector levers on the right sides of the board front panels. Service boards installed in remaining slots in the two areas have their ejector levers on the left sides of the board front panels. |
| Upper portion: IU17-IU32 | |||
| System control and cross-connect board area | 2 CTU system control boards and 7 cross-connect boards | Cross-connect boards: IU71-IU77 | Cross-connect boards are configured in M:N backup mode. The cross-connect boards provide cross-connections for service boards. The system control boards are configured in 1+1 backup mode. The active system control board manages and provides a clock to all other boards in the equipment. It also provides for inter-NE communication. When a U32 Standard subrack is used as a pure regeneration subrack, no cross-connect board is required. |
| CTU: IU70, IU78 |
