Installing a Power Module

Installing a Power Module


  • If a S12700 switch is running a version prior to V200R010C00, it does not allow mixing of AC and DC power modules or power modules of different power values. If the switch is running V200R010C00 or a later version, it allows mixing of 2200 W AC and DC power modules.
  • When the number of standby power modules is 0, the power modules do not work in backup mode.
  • Power modules of different models cannot allow mixing in the PoE power slot.
  • Cover all the vacant slots with filler panels to ensure good electromagnetic shielding, heat dissipation, and dustproof performance.


  • ESD wrist strap or ESD gloves
  • Phillips screwdriver


  1. Wear an ESD wrist strap or a pair of ESD gloves. When wearing an ESD wrist strap, insert the other end in the ESD jack of a device and ensure that the device is reliably grounded.
  2. (Optional) Remove the filler panel (if any) from the power module slot.
  3. Install the power module into the power module slot.

    The S12700&S12700E series switches support two types of power modules, as shown in a and b of Figure 8-1.

    1. Raise the ejector lever. With one hand beneath the power module, use the other hand to grasp the panel and slowly slide the power module into the slot, until the hook on the ejector lever is attached to the interior side of the power module slot. See callout 1 in Figure 8-1.
    2. Lower the ejector lever to ensure that the power module is completely seated in the slot. See callout 2 of Figure 8-1.
    3. (Only for a power module secured with a captive screw) Use a Phillips screwdriver to tighten the captive screw on the ejector lever. See callout 3 in Figure 8-1.

  4. Install filler panels on all the vacant power module slots.
