Configure PSE Parameters

Use this task to configure PSE settings, which define how ports manage the power that they supply to devices.

  1. Select the add icon.
  2. Enter a name.
  3. For Power Mode, select 802.3af or 802.3at.
    802.3af (PoE) can deliver 15.4 watts over Cat5 cables. 802.3at (PoE+) can deliver up to 30 watts over Cat 5 cables with 25.5 watts available to devices.
  4. For Power Limit, limit the available PoE power to a level lower than the maximum allowed by the power mode.
  5. Select a Priority from the drop-down list:

    Low: If the total powered device (PD) power consumption exceeds the PSE power budget, power output is modified to bring the total consumption back to within the PSE power budget.

    High: When the total PD power consumption exceeds the PSE power budget, power output is modified only after ports with low priority PSE profiles are regulated.

    Critical: When the total PD power consumption exceeds the PSE power budget, power output is shut down last.

  6. Optional: Enter a description.
  7. Select Save.
