Downlink Service interface

48*25GE SFP28

Note:

1. A 25GE port works at 25 Gbit/s by default and cannot work at 1 Gbit/s or 10 Gbit/s through auto-sensing, but can be configured to work at 10 Gbit/s or 1 Gbit/s through commands. When a 25GE port is configured to work at 10 Gbit/s or 1 Gbit/s, the rate of the other three ports in the same group also needs to be switched. The rate of a single port cannot be switched independently.

2. 10GE LRM/80 km linear optical modules are not supported.

3. The 1000BASE-X auto-negotiation function is not supported. To connect the two interfaces at both ends of a link, disable the auto-negotiation function of the peer interface. After the connection, in some port failure scenarios, the interface on one end may be Up and the interface on the other end may be Down.
