The OSN3500 EGT2 single boards are available in feature versions N1 and N2. the single boards are Ethernet transparent transmission single boards, which are mainly used to solve the telecommunication application areas such as Ethernet service access, bandwidth management, etc. The single boards support functions and features such as LCAS and test frame. The single board supports functions and features such as Ethernet service transparent transmission, LCAS and test frame. The single board consists of an Ethernet access module, a mapping module, an interface conversion module, a logic control module, a clock module, and a power module. The faceplate of the veneer has veneer indicators, interfaces, barcodes, and laser security levels. There are no dial codes or jumpers on the veneer for veneer setup. The single board supports a variety of Ethernet functional features such as LCAS, LPT, etc. and can be configured according to actual needs.
An error occurs when configuring the VC-3 service on the EGT2 veneer that has been configured with the VC-4 service, and the fault is eliminated after the service type is uniformly configured.

Fault category
Ethernet Failure
Phenomenon Description
When a customer configures a VC-3 service on the second port of an EGT2 board that already has a VC-4 service, the network management prompts that the service cannot be configured.
Cause Analysis
- On the same port, EGT2 and the single board supporting the RPR feature cannot configure VC-3 and VC-4 services at the same time, regardless of whether the same VCTRUNK is used or not.
- The six GE ports of the EGT6 single board correspond to the six VCTRUNK ports one by one. the six GE ports are divided into three groups in terms of data mapping (DM) chips, as shown in Table 1, and different types of services can be configured for the VCTRUNKs in different groups.

Group VCTRUNK No. 1 1 & 2 2 3 & 4 3 5 & 6
Procedure
- After the service type (VC-3 or VC-4) is configured in a uniform manner, the fault is eliminated.
Reference Information
The OptiX OSN 7500 devices support the RPR feature on single boards such as EMR0, EGR2, and so on.
