Huawei switch PoE disabled
PoE can be enabled or disabled on Huawei S-series switches using interface-specific commands in system view.
Checking PoE Status
To verify whether your Huawei switch supports PoE and its current status, use the following commands:
display poe device– checks if the device supports PoE.display poe information– shows running PoE information, including maximum output power, current consumption, and power management mode.display poe power– displays power usage per interface and overall allocation .
Enabling or Disabling PoE
By default, PoE is enabled on most interfaces. To manage PoE on a specific interface:
- Enter system view:
system-view
- Enter the interface configuration:
interface gigabitethernet 1/0/0
- Disable PoE:
undo poe enable
- Enable PoE:
poe enable
This allows you to control whether the interface supplies power to connected devices .
Forcing PoE Power
If the switch cannot negotiate power with a connected 48V standard PoE device, you can force power supply:
poe force-power
This ensures the device receives power even if automatic negotiation fails .
Additional PoE Management
- You can configure maximum output power per interface using
poe max-power. - Power high inrush can be enabled with
poe high-inrush enableif needed. - To disable automatic power-on/off for PDs on specific ports, use
poe power-policy port-index-priority disable. By following these commands, you can troubleshoot and re-enable PoE on Huawei switches, ensuring connected devices receive the required power.
