Downlink Service interface

48 x 10GE SFP+ (10GE LRM/80 km linear optical modules are not supported. In addition, 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.)

Uplink Service interface

6*100GE QSFP28 (Note: 1. Each 100GE QSFP28 port can be used as a 40GE port. 2. A 100GE QSFP28 port cannot be split into 4x25GE and 4x10GE ports.)

Service port supporting the stack function

10GE optical ports and 100GE optical ports

4

Redundant fans

The device supports 3+1 backup of fan modules that work in hot standby mode. The system can operate properly for a short period of time after a single fan module fails. You are advised to replace the faulty fan module immediately.

Heat dissipation mode

Air cooling

Airflow direction

Port-side air intake or port-side air exhaust, depending on the fan modules and power modules that are used. The fan modules and power modules must have the same airflow direction.
