The switch has two power supply slots, in which pluggable power modules can be installed. A chassis can use one or two power modules. In particular, dual power modules provide higher reliability.

The switch supports dual power modules working in 1+1 backup mode. When both power modules are working properly, each power module provides half of the power for the switch. If one power module fails, the other one provides full power for the switch.

All power modules are hot swappable.

The switch has fan slots in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability.

It is recommended that fan modules be properly installed on a switch to ensure normal switch operating. Fan modules work in hot backup mode. If a fan module fails, the system can still work properly for a short period of time. However, you are advised to replace the faulty fan module immediately.

All fan modules are hot swappable.

Port for inputting and outputting 50GE/25GE/10GE/GE optical signals

By default, the port is a 25GE port and supports 10GE auto-sensing. You can run a command to change the port rate to 50 Gbit/s or 1 Gbit/s. Every eight ports (1 to 8, 9 to 16, 17 to 24, 25 to 32, 33 to 40, and 41 to 48) form a group. In versions earlier than V300R024C00, when the rate of a 25GE port is changed to 50 Gbit/s or 1 Gbit/s, the rate of the other seven ports in the same group needs to be changed together. In V300R024C00 and later versions, the rate of a single port in a group can be changed independently, but all ports in the port group support only two rates, which can be any of the following combinations: 50GE/25GE, 25GE/10GE, 25GE/GE, 10GE/GE. A high-speed port license is required to achieve the 50 Gbit/s port rate.

Port for inputting and outputting 200GE/100GE/40GE optical signals

1. A 100GE port can be configured to operate at 40GE. Every two ports (1 and 2, 3 and 4, 5 and 6, and 7 and 8) form a group. When a port is split into 4 x 10GE or 4 x 25GE ports, the other port in the same group also needs to be split.

2. A 100GE port can be configured to operate at 200GE. Every two ports (1 and 2, 3 and 4, 5 and 6, and 7 and 8) form a group, and the rate of the two ports in the same group must be switched together. A high-speed port license is required to achieve the 200 Gbit/s port rate. In versions earlier than V300R024C00, a 200GE port can be split only into 4 x 50GE ports. In V300R024C00 and later versions, a 200GE port can also be split into 2 x 100GE (100GE: 2 x 50GE) ports, and the port rate can be reduced to 100GE (100GE: 2 x 50GE). In this case, the first port of the 2 x 100GE ports is used. A 200GE port can be split into 2 x 100GE ports (100GE: 2 x 50GE) only when an AOC is connected. It cannot be split when a copper cable is connected.
