Planning and Implementation for the HP 2620-PoE+ Switches
PoE Provisioning
PoE Provisioning
■ The 2620-24-PPoE+ Switch can supply up to 126 watts of PoE+ power to
ports 1-12 for PoE and PoE+ applications that are compatible with the
IEEE 802.3af and 802.3at standards and some pre-standard devices.
■ The 2620-24-PoE+ Switch can supply up to 382 watts of PoE+ power to
ports 1-24 for PoE and PoE+ applications that are compatible with the
IEEE 802.3af and 802.3at standards and some pre-standard devices.
■ The 2620-48-PoE+ Switch can supply up to 382 watts of PoE+ power to
ports 1-48 for PoE and PoE+ applications that are compatible with the
IEEE 802.3af and IEEE 802.3at standards and some pre-standard devices.
This reduces the average per port wattage by half as compared to the 2620-
24-PoE+ Switch.
An external power supply, the HP 630 Redundant and/or External (HP 630
RPS/EPS) power supply (J9443A
) can be connected to either of the 2620-24-
PoE+ or the 2620-48-PoE+ Switches to provide redundant or extra PoE+
power. The 2620-24-PPoE+ does not support external PoE+ power.
