    802.3af standard. On the Switch 2650-PWR, you can optionally provision ports 1-24 with 406 watts of internal power and ports 25-48 with 368 watts of external power by adding an HP ProCurve 600 Redundant and External Power Supply (HP RPS/EPS; J8168A).

    Note that power priority rules apply only if PoE provisioning on the switch becomes oversubscribed. External Power Supply; for example, an HP 600 RPS/EPS. An EPS device provides power to provision PoE ports on a switch. See also "RPS", below.

    10/100Base-TX PoE RJ-45 ports on the switch. The Switch 2626-PWR and 2650-PWR are endpoint PSEs. Redundant Power Supply; for example, an HP 600 RPS/EPS. An RPS device provides power to a switch if the switch’s internal power supply fails. RPS power does not provision PoE ports on a switch whose internal power supply has failed.

  • Page 8: Pd Support

    General PoE Operation PD Support The switch must have a minimum of 15.4 watts of unused PoE power available when you connect an 802.3af-compliant PD, regardless of how much power the PD actually uses. On the Switch 2626-PWR, there will always be enough power available to connect and support 802.3af PoE operation on all 24 10/ 100-TX ports.

  • Page 9: Power Priority

    PDs connected to ports 1 - 24 (2626-PWR) or 1 - 48 (2650-PWR). If both EPS ports on the HP 600 RPS/EPS are connected to switches, each switch can receive 184 watts of PoE power. If only one switch is connected to the EPS port, that switch can receive 368 watts of PoE power.

  • Page 10: How Does The Switch Prioritize Power Allocations

    General PoE Operation How Does the Switch Prioritize Power Allocations? The switch simul­ taneously uses two priority methods: The priority class method enables port PoE priority class assign­ ■ ments of Low (the default), High, and Critical. ■ The port-number priority method gives a lower-numbered port priority over a higher-numbered port within the same configured priority class.

  • Page 11: Configuring Poe Operation

    Configuring PoE Operation Configuring PoE Operation In its default configuration, PoE support is enabled on the switch’s 10/100Base- TX ports, with Priority set to Low and the power threshold set to 80 (%). Syntax: power threshold < 1 - 99 > The power threshold is a configurable percentage of the total PoE power available on the switch.
  • Page 12 Configuring PoE Operation Syntax: interface [e] < port-list > power [ critical | high | low ] Reconfigures the PoE priority level on < port-list >. For a given level, the switch automatically prioritizes ports by port number (in ascending order). If there is not enough power available to provision all active PoE ports at a given priority level, then the lowest-numbered port at that level will be provisioned first, and so on.
