Power Supplies
There are two power supplies that can be installed into the E3800 switches:
■ HP X311 400W 100-240VAC to 12VDC PS (J9581A) -- a 400 watt power
supply for the Non-PoE switches. The 400 watt power supply does not
provide any PoE power. The 400 watt power supply is keyed such that it
will not fit into the PoE+ switches.
■ HP X312 1000W 100-240VAC to 54VDC PS (J9580A) -- a 1000/700 watt
power supply for the PoE+ switches. The 1000/700 watt power supply
provides PoE/PoE+ power. The 1000/700 watt power supply is keyed such
that it will not fit into the Non-PoE switches. When supplied with 110 V,
the power supply runs at a max of 700 W and when supplied with 220 V,
the power supply runs at a max of 1000 W.
For more power supply information see page 2-17.
Power Connector
The E3800 switches do not have a power switch; they are powered on when
connected to an active AC power source. These switches automatically adjust
to any voltage between 100-127 or 200-240 volts and either 50 or 60 Hz. There
are no voltage range settings required.
Module Slot
Each of the E3800 switches has one module slot that can accept the HP E3800
Stacking Module that provides high-speed connectivity to other E3800
switches. Only the E3800 switches support this module.
