Fixed switches:
- In versions earlier than V100R006C01, the S2700, S3700, and S5700 cannot use AC and DC power modules simultaneously.
- In V100R006C01 and later versions, the S3700-26C-HI, S5700-28C-HI, and S5700-28C-HI-24S can use AC and DC power modules simultaneously.
- In V200R001C00 and later versions, the S5710-28C-EI and S5710-52C-EI can use AC and DC power modules simultaneously.
- In versions earlier than V200R005C00, the S6700 cannot use AC and DC power modules simultaneously.
- In V200R005C00, the S5700-EI (non-PoE), S5700-SI (non-PoE), and S6700 can use AC and DC power modules simultaneously.
- In V200R006C00 and later versions, the S5720-HI (non-PoE) can use AC and DC power modules simultaneously.

S7700 and 9300:

When a switch is running a version earlier than V200R010C00, it does not allow mixing of AC and DC power modules or power modules of different power values in the same type of power slots (system or PoE power slots).


  • When a switch is running V200R010C00 or a later version, it allows mixing of AC and DC power modules in its system power slots.

    • Two 800 W AC power modules and one 1600 W DC power module are interchangeable in different power supply areas, that is, two 800 W AC power modules in area A (or B) and one 1600 W DC power module in area B (or A).
    • Mixing of 2200 W AC and DC power modules are supported.

  • S9700 and S12700�?When a switch is running a version earlier than V200R010C00, it does not allow mixing of AC and DC power modules or power modules of different power values. When a switch is running V200R010C00 or a later version, it allows mixing of 2200 W AC and DC power modules.

    AC and DC power supply on S series switches
    You can check whether an S series switch supports AC or DC power supply based on the following guidelines: 1. Check the switch model. If the model contains AC, the switch supports AC power supply. If the model contains DC, the switch supports DC power supply. 2. Check the power module. Differentiate AC and DC switches based on the power module. Power modules are divided into non-PoE and PoE power modules. You can also use the Hardware Query Tool at Hardware Query Tool.

    Does a 3000 W AC&high-voltage DC power module support AC power input on CE12800 series switches
    A 3000 W AC&high-voltage DC power module supports 220 V/110 V AC power input and 240 V DC input, and provides 53.5 V DC/3000 W output. Description: When AC power supply is used and the input voltage is lower than or equal to 175 V AC, the rated output power reduces to 1500 W.
