What is the difference between SEP1 and SEP for Huawei OSN3500 devices?

A: There is no difference between these two kinds of boards in terms of hardware, in fact, they are all SEP1 a single board with only one kind of silkscreen.

The purpose of the distinction is for the network administrator to be able to manage this type of single board normally.

SEP1: processing board with 2 * 155M electrical interface, can not take the interface board, does not support TPS;

SEP: the electrical port on the processing board can not be connected to the service, must be with an interface board (otherwise the port is 0), if it is an electrical interface board supports TPS, does not support the protection between electrical interface boards with different port numbers;.

The single board software is recognized by the user-configured interface board type, when the configured interface board type is found to be inconsistent with the current interface board type, the single board will be hard reset to re-establish the single board type.

Note: When the physical board type and logical board type are SEP, only the logical interface board is deleted, in order to facilitate the user to replace and upgrade the interface board operation, the board will not be reset, the logical and physical board type also remains unchanged.
