Huawei OSN3500 N1EGS4 and N4EGS4 single boards support 1000BASE-T RJ-45 Ethernet electrical interfaces (the electrical interfaces are hot-swappable, and the corresponding single board barcodes are SSN1EGS414 and SSN4EGS414), and the electrical interfaces support the self-negotiation function, and the transmission distance can reach up to 100 m. Currently, the N1EGS4 is discontinued, so what settings do you need to set up to use the EGS4 single boards with the electrical interface? What settings do I need to make for the EGS4 single board?

Reason Analysis

On OptiX OSN 1500/2500/3500/7500, the N1EGS4 board is supported in V100R004 and above versions, and the minimum host software version is 5.36.14.32/5.21.14.32, and the N4EGS4 board is supported in V100R009 and above versions, and the configured logical board is N4EGS4. N4EGS4, the minimum host software version supported is 5.36.19.13/5.21.19.13. The following settings are required when using the EGS4 board with a power interface.

Procedure

The following settings are required when using the N1EGS4 single board with a power interface:

Verify that the bar code of the N1EGS4 single board is SSN1EGS414.

Verify that the host version is 5.36.14.32/5.21.14.32 and above.

The host does not distinguish whether the single board is an optical or an electrical interface after it is started, and there is no need to make other settings on the network management, so that it can be used after directly configuring the service and other attributes.

Operation Steps

The following settings are required when using the N4EGS4 single board with a power interface:

Verify that the bar code of the N4EGS4 single board is SSN4EGS414.

Verify that the host version is 5.36.19.13/5.21.19.13 and above.

Add the logical single board as N4EGS4 on the network management (do not use the multi-board ID function to add it as N3EGS4, otherwise the electrical interface is still not supported).

Change the port type on the network management: Ethernet Configuration - Ethernet Interface Management - Ethernet Interfaces - External Ports - Change the port logical type to SDH electrical interface (the single-board power-on defaults to SDH optical interface, which needs to be changed to SDH electrical interface, or else it will report MOD_TYPE_MISMATCH, which indicates that the set SFP module type is not the same as the actual module type, and it affects the (the opening of the service).

Recommendation Summary

The N4EGS4 single board from the R9 release supports configuring the logical board as N3EGS4 or N4EGS4, before R9 the N4EGS4 single board can only be configured as N3EGS4 by the Multi Board ID function, if it is configured as a N3EGS4 single board then it only has the function of a N3EGS4 single board, so if you add a logical board as N3EGS4, even if the physical type is SSN4EGS414, there is no functional interface on the network management to change the logical port to SDH electrical interface.

For this EGS4 single board, the MOD_TYPE_MISMATCH alarm is a new alarm added from the N4 series, which does not exist for N1 and N3.

SSN3EGS214 and other EOS boards also support Gigabit Ethernet interfaces from the R9 host, so please pay attention to this when using them.
