HJ-iAN2200 is a new generation centralized MSAP device, composed of a chassis and unit boards. The chassis adopts a 19-inch 7U plug-in design (chassis dimensions: 311MM*293MM*482MM), with a PGND screw and anti-static interface at the lower right corner of the chassis; the unit boards include a fan board, power board, network management board, SDH uplink board, GE Ethernet core aggregation board, service boards, etc. The fan board is located at the top of the device, providing ventilation and heat dissipation; the power board supplies +12V power to the device; the network management board provides network management functions; the SDH uplink board offers cross-connection and synchronous timing functions; the GE Ethernet core aggregation board provides Ethernet switching functions; the service boards include various service branch boards to meet customer needs.
1. Equipment Structure
19-inch 7U plug-in box, 16 card slots
LVDS clockless backplane wiring, independent bus structure for SDH and GE
Dual SDH uplink boards, dual Ethernet core aggregation boards, dual network management boards, dual power boards structure, making the system safer and more reliable
2. SDH Uplink Board
Up to 4 STM-4 or STM-1
Group optical interfaces (2 per board) use LC-type SFP optical transceiver modules, supporting hot swapping
Maximum cross-connect capacity is 32VC4x32VC4, 96TU-3x96TU-3, 2016VC12x2016VC12
SDH uplink board 1+1 protection, achieving hot backup of clock modules
Single/dual-ended 1+1 linear multiplex section protection and SNCP protection
Topologies including point-to-point, chain network, ring network, and tangential ring
3. Ethernet Core Aggregation Board
Up to 4 Gigabit optical ports and 4 Gigabit electrical ports
Each board can independently aggregate 8 groups of Gigabit Ethernet data from the backplane
5. Multiple Service Boards
Supports downstream STM-1 optical branch boards, E1, EOSDH, EOPDH and various branch service boards
Can interconnect with remote Ethernet fiber transceivers, SDH devices, MSTP devices, etc.
Supports 1+1 channel protection
