Supported

RJ45

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.)

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.)

10GE optical ports and 100GE optical ports

To obtain data of this specification item, see the corresponding datasheet or contact the product sales personnel.

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.

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.

-40°C to +70°C (-40°F to +158°F)

0°C to 40°C (32°F to 104°F) at an altitude of 0 to 1800 m (0 to 5906 ft.)
Note: When the altitude is between 1800 m and 5000 m (5906 ft. and 16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).
