PoE PSE Port Configuration

Use the PoE PSE Port Configuration dialog box to set up the PoE PSE Port parameters.

To access PoE PSE Port Configuration screen, go to PoE PSE.

PoE > PoE PSE Port Configuration

Port Select individual PoE ports across the entire switch.
PoE PSE Port Name Type a name to the PoE PSE port. For example, the name “Camera-1” is assigned to port Gi0/2.
Admin Status From the pull down menu, select the port status:
  • Enable—to enable PoE PSE Port functionality.
  • Disable—to disable PoE PSE Port functionality.
Force Power From the pull down menu, select the forcing power on the Ethernet port without negotiation. The options are
  • Enabled—to enable the forcing power on the Ethernet port.
  • Disabled—to disable the forcing power on the Ethernet port.
By default,  forcing power on the Ethernet port without negotiation is disabled. This mode requires PoE PSE mode PoE++ 60W as it can supply up to 60W and will switch to this mode when the command is issued if not already in this mode as indicated.
PSE Mode From the pull down menu, choose a PoE PSE mode. The PoE PSE mode allows the user to setup to which IEEE standard the PoE controller will conform to and set the maximum power that can be drawn. 6 options are available.
  • PoE++15W—bt/at/af 4-Pairs 15W max
  • PoE++30W—bt/at/af 4-Pairs 30W max
  • PoE++60W— bt/at/af 4-Pairs 60W max
  • PoE+4P60W—Pre-bt 4-Pairs 60W max
  • PoE+A30W—at/af ALT-A 30W max
  • PoE+B30W—at/af ALT-B 30W max
Power Priority From the pull down menu, select the power priority of the individual ports. The PoE PSE priority is used to decide which port to power down when there is not enough power for all the ports either on the chassis (reaching maximum external power level) or on a line module.
Note:

The low priority port will be shut down first, followed by the high priority port, then followed by the critical ports. Within these levels, smaller port numbering has higher priority than larger port numbering.

  • Low—this is the default.
  • High
  • Critical
Power Budget From the pull down menu, select the power budget for the individual ports. The PoE PSE power budget option allows the user to select what port power value is used to calculate when too much power is drawn and the ports need to be powered down.
  • Class

    The “class” based power budget option will provide for a more stable system but can be inefficient. For example, if eight Class 6 devices are connected to a single line module, only four will be powered when in “class” based power budget mode because of the power limit of the line module.

    However, if these devices only draw 20W each, all eight devices can be powered in “usage” power budget mode.

  • Usage

    Devices that use a constant amount of power can be candidates for “usage”-based power budget, while devices that use variable amount of power would probably be better under the “class”-based power budget.

Legacy Detect From the pull down menu, select to enable detection of older capacitive detectable devices that do not adhere to the IEEE 802.3 standard and require some extra detection timing.
  • Enabled—to enable the detection of older capacitive detectable devices that do not adhere to the IEEE 802.3 standard and require some extra detection timing.
  • Disabled—to enable the detection of older capacitive detectable devices that do not adhere to the IEEE 802.3 standard. This is the default option.
Buttons
  • Apply—modifies attributes and saves the changes.
  • Reset—resets the changes.
