Planning and Implementation for the HP 2610-PoE Switches
PoE Provisioning
PoE Provisioning
■ The 2610-24-PPoE Switch provisions ports 1-12 with 126 watts.
■ The 2610-24-PoE Switch provisions ports 1-24 with 406 watts.
■ The 2610-48-PoE Switch provisions ports 1-48 with 406 watts. This
reduces the per port wattage by half as compared to the 2610-24-PoE
Switch.
These switches support PoE applications compatible with the IEEE 802.3af
standard and some pre-standard devices.
However, by connecting a 600 RPS/EPS or a 610 EPS, you can optionally
provision ports 25-48 on the 2610-48-PoE Switch with 408 watts of external
PoE power, thereby bringing the per port wattage up to 15.4 watts per port,
unless you have the other EPS port of the 600 RPS/EPS or the other port of a
pair on the 610 EPS connected to a HP PoE device. In this case you cannot
provision the full 408 watts to the 2610-48-PoE Switch – only half, or 204 watts.
Table 5-1. PoE Power Provisioning
PoE Devices Internal Only Internal and EPS EPS Only
PoE for 2610-24-PPoE
Switch
126 watts available to
ports 1-12.
126 watts available to
ports 1-12 (provided by
the internal source). 408/
204* watts available,
provided by the EPS
source.
If the switch’s internal power
supply has failed, the EPS
provides 408/204* watts to
ports 1-12.
PoE for 2610-24-PoE
Switch
406 watts available to
ports 1-24.
Redundant 408/204*
watts available to ports 1-
24, but only if the internal
power supply fails.
408/204* watts available to
ports 1-24. (The EPS provides
PoE power to ports 1-24 only if
the internal power supply
fails.)
PoE for 2610-48-PoE
Switch
406 watts available to
ports 1-48.
406 watts available to
ports 1-24 (provided by
the internal source). 408/
204* watts available to
ports 25-48 (provided by
the EPS source).
The internal power supply has
failed, and the EPS provides
408/204* watts to ports 1-48.
Note that 22 watts of this
power is always allocated
exclusively to ports 1-24 or 25-
48.)
* If both EPS ports on the 600 RPS/EPS or both ports of a pair on the 610 EPS are connected to switches, each switch
can receive 204 watts of power. If a single switch is connected to the EPS ports, that switch can receive 408 watts.
