Planning and Implementation for the HP 5400zl/8200zl Switches

PoE Provisioning

Each chassis provisions (allocates power to) ports 1-24 of each module with

the watts associated with the specific power supply installed. The power for

PoE applications is compatible with the IEEE 802.3af standard and some pre-

standard devices. As soon as a module is installed into the switch, 22 watts is

reserved for its use.

An external power supply, the HP Switch zl Power Supply Shelf (J8914A) can

be connected to these switches to provide extra PoE power. The Power Supply

Shelf can be connected to up to two switches and provide up to 1800 watts

depending on which power supplies are installed.

■ The 5406zl/8206zl 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 5400zl/8200zl 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 5400zl/

8200zl chassis or Power Supply Shelf.
