HUAWEI SXCSA SSN1SXCSA 03030DKF Super Cross-Connect And Synchronous Timing Board

HUAWEI SXCSA SSN1SXCSA 03030DKF Super Cross-connect and Synchronous Timing Board

The Huawei SSN1SXCSA (Product Code: 03030DFK), also known as the SXCSA, is a high-capacity Super Cross-Connect and Synchronous Timing Board designed for Huawei‘s Huawei OSN3500 intelligent optical transmission system. As the core cross-connect unit of the OSN 3500 platform, it provides flexible service scheduling, clock input/output, and timing distribution to other boards within the system.

The SXCSA is available in two functional versions: N1SXCSA (this model) and ND0SXCSA, with part numbers 03030DFK and 03030KBM respectively. The N1SXCSA supports board compatibility substitution, allowing it to replace N1EXCSA or N1UXCSA boards while maintaining the same configuration and service status.

This board is typically deployed in 1+1 hot backup configuration for carrier-grade reliability, and is used in metro network aggregation and backbone layers

• Redundancy Configuration: It is highly recommended to configure two SXCSA boards in 1+1 active/standby mode for carrier-grade reliability. A single board can operate independently but is not recommended for production environments.

• Same Board Type Required: When using two cross-connect boards in a chassis, both must be of the same type. SXCSA cannot be mixed with UXCSA, IXCSA, or other cross-connect boards.

• Board Substitution: N1SXCSA can replace N1EXCSA or N1UXCSA boards. After replacement, the configuration and service status remain unchanged.

• External Clock Interfaces: The SXCSA board has no front-panel interfaces. All external timing interfaces (2MHz/2048kbit/s) are provided through the AUX board.

• Logical Board Configuration: During initial deployment, if the logical board is incorrectly configured as EXCSA, low-order cross-connect services may fail. Reconfigure the logical board type to SXCSA to resolve the issue.

• Compatibility Verification: Compatibility depends on the specific chassis model and system software release. Always verify compatibility with your supplier before purchasing.
