| Power module protection |
The system power modules support: 1. Reversed connection protection, which prevents the power module from being burnt when reversely connected. 2. Protection against input overcurrent, output overvoltage, output overcurrent, output short circuit, and overtemperature conditions. 3. Current sharing and hot swapping. 4. Fault isolation when the switch is configured with dual power modules. That is, when one power module fails, the other power module is not affected.

| Downlink interface |
There are thirty-two 40GE QSFP+ interfaces in total. Uplink and downlink interfaces are not distinguished. Note: Four configuration modes are available for splitting a 40GE interface into four 10GE interfaces: Mode 1: Among the first 16 interfaces, the first 12 interfaces can be dynamically split, and the last 4 interfaces cannot. Among the last 16 interfaces, the first 12 interfaces can be dynamically split, and the last 4 interfaces cannot. Mode 2: Among the first 16 interfaces, the last 12 interfaces can be dynamically split, and the first 4 interfaces cannot. Among the last 16 interfaces, the first 12 interfaces can be dynamically split, and the last 4 interfaces cannot. Mode 3: Among the first 16 interfaces, the first 12 interfaces can be dynamically split, and the last 4 interfaces cannot. Among the last 16 interfaces, the last 12 interfaces can be dynamically split, and the first 4 interfaces cannot. Mode 4: Among the first 16 interfaces, the first 13 interfaces can be split into 10GE interfaces, and the last 3 interfaces are unavailable. Among the last 16 interfaces, the first 13 interfaces can be split into 10GE interfaces, and the last 3 interfaces are unavailable. That is, if mode 4 is configured, a total of one hundred and four 10GE interfaces are provided, and no split command needs to be configured. A new configuration mode takes effect only after a reboot.
