Downlink Service interface

32 x 100GE QSFP28/32 x 200GE QSFP56

1. 100GE ports can be configured as 40GE or 50GE (50GE: 2 x 25GE) ports but cannot be split into 2 x 50GE ports.

2. A 100GE port can be split into 4 x 25GE, 4 x 10GE, or 2 x 50GE (50GE: 2 x 25GE) ports. Ports 1 and 2, 3 and 4, ..., and 31 and 32 form different groups. The two ports in a group need to be split together. For example, ports 1 and 2 form a group. When port 1 is split, port 2 is also split. 200GE ports can be configured as 40GE/100GE ports and can be split into 2 x 100GE (100GE: 2 x 50GE) ports. In V300R020C00, ports 1 and 2 cannot be split, and 200GE ports cannot be split. This restriction does not apply to V300R020C10 and later versions.

Nota:

1. Support for optical modules:

(1) In the case of port-side air intake, downlink 100GE/200GE ports support 100G-SR4/CWDM4/LR4/4WDM.

(2) In the case of port-side air exhaust, downlink 100GE/200GE ports support 100G-SR4/CWDM4.

2. Support for copper cables: When 200GE copper cables are used, contact Huawei engineers for interconnection verification.

Uplink Service interface

8 x 400GE QSFP-DD

1. 400GE ports can be used as 200GE, 100GE, and 40GE ports.

2. In V300R020C10, a 400GE port can be used as a 200GE/100GE/40GE port and can be split into 4 x 100GE (100GE: 2 x 50GE but not 4 x 25GE) ports. Other port split modes, such as 2 x 200GE/2 x 100GE/2 x 40GE/8 x 50GE/8 x 25GE/8 x 10GE/4 x 50GE/4 x 25GE/4 x 10GE, are not supported. In V300R021C10, a 400GE port can be dynamically split into 2 x 200GE ports. Currently, 2 x 200GE AOCs and 2.5 m copper cables can be used.

Nota:

1. Support for optical modules:

(1) In the case of port-side air intake, uplink 400GE ports support 400G-SR8/DR4/FR4. When the ambient temperature ranges from 0iC to 35iC, 400G-LR8 is supported. However, the noise of the device exceeds the threshold at room temperature.

(2) In the case of port-side air exhaust, uplink 400GE ports support 400G-SR8. However, the noise of the device exceeds the threshold at room temperature.

2. Support for copper cables:

V300R021C10 and later versions:

40GE/100GE/200GE/400GE copper cables are supported. A 400GE port can be dynamically split into 2 x 200GE ports. 2.5 m copper cables can be used. When 200GE and 400GE copper cables are used, contact Huawei engineers for interconnection verification.

V300R020C10 and V300R021C00:

40GE/100GE/200GE/400GE copper cables are supported. After uplink ports are split, copper cables are not supported. When 200GE and 400GE copper cables are used, contact Huawei engineers for interconnection verification.

V300R020C00:

40GE/100GE copper cables are supported. After a port is split, copper cables are not supported. 200GE/400GE copper cables are not supported.
