PXES4P Switches
The PXES4P Series are designed to provide reliable operation, withstand higher
temperature environments, and provide the Direct DC power choices to the user to deploy
in uncontrolled temperature environments.
12VDC
The Internal 12V DC (8 – 15V DC) has a built-in terminal block for +, -, ground. The 9V
DC jack is also present. Detail information about the 12 VDC, the 24V DC and the –48V
DC is provided in the Technical Specifications Section 1.1.
The various models of Direct DC power type and extended ambient temperature
power supplies are numerous and your choice needs to be called out on your order.
Note:
When connected to a - 48 V centralized dc source these products are to be installed
only in Restricted Access Areas (dedicated equipment rooms, electrical closets or the like).
3.6 Powering the PXES4P with 12V, 24V or –48VDC power input
PXES4P Switches
The PXES4P is reliably equipped with a Direct DC power supply, and have built-
in screw terminals for secure attachment of the power
leads. Three models support a range of power input types.
The three model choices are for use with 12VDC, 24VDC
or -48VDC power. DC power input may be chosen for
high-availability.

3.7 PXES4P, DC-powered, -48VDC, 24VDC and 12VDC Installation
This section describes the proper connection of the -48VDC leads (or 24VDC,
12VDC leads) to the Direct DC power terminal
block on the PXES4P hardened media converter (as
shown in Figure above). The DC terminal block on
the PXES4P is located on the left side of the unit
and is equipped with three (3) screw-down lead
posts. The power terminals are identified as positive
(+) and negative (-), and they are floating inside the unit so that the user if desired may
ground either of the terminals. The chassis is "earth" or ground (GND).
