The actual installation slots of the Optix OSN2500 SSQ5CXLLN veneer differ from those shown in the U2000 network management, and the parameters of the CXLLN veneer can be configured through the U2000 network management system.The logical boards of the Q5CXLLN veneer in the network management when it is plugged into the new backplane are Q2SLN, UCXL, and GSCC.At this time, the logical boards of the Q5CXLLN veneer in the network management are Q2SLN, UCXL, and GSCC. slots as shown in Table 1. Table 1 Q5CXLLN Logical Single Board Logical Slots on the Network Manager (New Backplane)
| Single Board | Logical Board | Logical slot |
|---|---|---|
| CXLLN | Q2SLN | slot 9, slot 10 |
| UCXL | slot 80, slot 81 | |
| GSCC | slot 82, slot 83 |
The logical boards on the network management when the Q5CXLLN single board is plugged into the old backplane are Q2SLN, ECXL, and GSCC. at this time, the logical slots of the Q5CXLLN single board on the network management are shown in Table 2. Table 2 Q5CXLLN Logical Single Board Logical Slots on the Network Manager (Old Backplane)
| Single Board | Logical board | Logical slot |
|---|---|---|
| CXLLN | Q2SLN | slot 9, slot 10 |
| ECXL | slot 80, slot 81 | |
| GSCC | slot 82, slot 83 |

Problem Description
When OSN3500II is opened, it is found that the version number of Q5CXL single board is 5.21.xx.xx when queried on the network management, but it shows 5.36.xx.xx when queried on the command line.
Alarm Message
None
Process
It has been confirmed that this phenomenon exists in all OSN3500II versions. The purpose of doing so is to maintain consistency with OSN3500, and secondly, it is the need of network management modeling implementation. Simply put, OSN3500II has been converted to OSN3500 in order to maintain consistency with OSN3500, so the version number is converted in the network management.
Root Cause
None
Recommendation and Summary
This phenomenon does not exist when Q5CXL is applied to OSN1500 and OSN2500.
