Operating Rules
Overview of Switch PoE Operation
■ The Switch 3500yl-24G-PoE+ can supply up to 398 watts of PoE power
across the 24 ports. The Switch 3500yl-48G-PoE+ can supply up to 398
watts of PoE power across the 48 ports for PoE+ applications compatible
with the IEEE 802.3at standard.
■ The HP E3800-24G-PoE+-2SFP+ Switch, HP E3800-48G-PoE+-4SFP+
Switch, HP E3800-24G-PoE+-2XG Switch, and the HP E3800-48G-PoE+-
4XG Switch can supply up to 1080 watts of PoE/PoE+ power across all
RJ-45 ports depending on the voltage the power supply is connected to,
either 110 or 220 voltage, for PoE+ applications compatible with the IEEE
802.3at standard.
• If the power supply is connected to 110 volts, then the power supply
will supply 700 watts to the switch.
• if the power supply is connected to 220 volts, then the power supply
will supply 1000 watts to the switch.
For detailed information on the power supplies see the HP E3800
Switches Installation and Getting Started Guide. For information on
PoE/PoE+ usage see Chapter 12 “Planning and Implementation for the
E3800 Switches” of this manual.
■ The E5406zl/E8206zl switches can supply up to 1800 watts of PoE power
plus an additional 1800 watts with the addition of two external J9306A
power supplies.
■ The 5412zl/8212zl switches can supply up to 3600 watts of PoE power,
depending on which power supply is installed.
• The J8712A power supply provides up to 273 watts of PoE power. If
two J8712As are installed they can supply up to 546 watts of PoE
power and if four are installed they can supply up to 1092 watts of
PoE power.
• The J8713A power supply provides up to 900 watts of PoE power. If
two J8713As are installed they can supply up to 1800 watts of PoE
power and if four are installed they can supply up to 3600 watts of
PoE power. The two types of power supplies can be mixed (although
not recommended), that is, one or two J8712As and one or two
J8713As can be installed at the same time depending on which of the
Series E5400zl/E8200zl Switches are being used.
• The J9306A power supply provides up to 300 watts of PoE/PoE+
power at 110-127V and 900 watts of PoE/PoE+ power at 200-240V.
Mixing this power supply with any other type of power supply is NOT
supported.
Note HP highly recommends that power supplies are not mixed in the same
E5400zl/E8200zl chassis or Power Supply Shelf.
