Description
SSRDPCXL1614 Version Description
The PCXLN is available in one functional version, namely, R1.
Version Mapping
Board | Start Versiona |
---|---|
R1PCXLN | V100R009C03 |
a: If there is a replacement relationship between boards, the start version of the replaced board prevails. For example, on the OptiX OSN 3500, if an N3EAS2 board can replace an N1EAS2 board, the N3EAS2 board can be used in V100R008. |
SSRDPCXL1614 Board Updates
This section describes the hardware updates in V200R013C30 and later versions as well as the reasons for the updates. Any product versions that are not listed in the document means that they have no hardware updates.
SSRDPCXL1614 Application
The PCXLN provides service processing, service grooming, clock input/output, and communication control functions in the OptiX OSN 1500 system.
