FCC Certifications
This equipment generates and uses radio frequency energy and if not installed and used properly, that is,
in strict accordance with the instructions provided with the equipment, may cause interference to radio
and TV communication. The equipment has been tested and found to comply with the limits for a Class A
computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules, which are
designed to provide reasonable protection against such interference in a residential installation. However,
there is no guarantee that interference will not occur in a particular installation. If you suspect this
equipment is causing interference, turn your PoE Injector on and off while your radio or TV is showing
interference, if the interference disappears when you turn your PoE Injector off and reappears when you
turn it back on, there is interference being caused by the PoE Injector.
You can try to correct the interference by one or more of the following measures:
Reorient the receiving radio or TV antenna where this may be done safely.
To the extent possible, relocate the radio, TV or other receiver away from the PoE Injector.
Plug the PoE Injector into a different power outlet so that the PoE Injector and the receiver are on
different branch circuits.
If necessary, you should consult the place of purchase or an experienced radio/television technician for
additional suggestions.
CE Mark Warning
This is a class B device, In a domestic environment, this product may cause radio interference, in which
case the user may be required to take adequate measures.

1.0 Introduction
The Legrand DA2401 4 Port High Power PoE Injector (see Figure 1) provides up to 30 Watts of power
for any remote IEEE 802.3at high powered device, such as a third party multi-channel Wireless Access
Point, PTZ (Pan, Tilt & Zoom) camera, or Speed Dome IP camera over Cat 5e/6 wiring. The DA2401
has four “Data” input RJ45 jacks and four “Data and Power” output RJ45 jacks. The unit’s power is
supplied by an included 52VDC 2.31A AC adapter.
The DA2401 is designed so that multiple units may be easily mounted to a separately available bracket
(P/N AC1025) in an On-Q style enclosure (see Figure 2) and each unit may also be individually wall
mounted, as it has keyhole slots on the rear of the case.
The DA2401 complies with IEEE 802.3 (Ethernet), IEEE 802.3u (Fast Ethernet), IEEE 802.3ab (Gigabit
Ethernet) IEEE 802.3at (pre-standard Power over Ethernet), IEEE 802.3af (Power over Ethernet) and
10/100/1000Base-TX Ethernet standards.

1.2 Installation
The DA2401 High Power 4 Port PoE Injector is best installed during new construction in two steps; at
“rough-in” after the Electricians are done, but prior to drywall being installed, and at “trim-out” after the
drywall is installed and painted. These steps are detailed below:
A. “Rough-in” steps:
1. A single dedicated Cat 5e/6 should be run in the walls from the structured wiring enclosure
location in the home where the 4 Port High Power PoE Injector will be installed to each
location in the home where an IEEE 802.3at device will be installed (leave extra cable at both
ends).
NOTE: Run Cat 5e/6 cable at least 12” from electrical cabling (preferably in a separate stud
cavity) and cross electrical cables at a 90° angle. Use loose Velcro-style cable ties for
bundling. If stapling is required, use specialty staples to avoid compressing the cable.
2. At the selected locations, refer to the installation instructions provided with the IEEE 802.3at
device for recommended use of electrical gang boxes or low voltage brackets, with the extra
Cat 5e/6 cable in the box, or attached in such a way that it may be fished out after the drywall
is installed.
B. “Trim-out” steps:
1. The Cat 5e/6 cable that was secured at each of the locations should be pulled out and
terminated with an RJ45 plug following standard TIA 568A recommendations and attached to
the IEEE 802.3at device which is then installed.
2. In the structured wiring enclosure the Cat 5e/6 cables from the remote locations are
terminated with RJ45 plugs for direct connection to the DA2401 “Data and Power” output
jacks once the DA2401 is installed.
3. Each 4 Port High Power PoE Injector is first attached to the separately available AC1025
bracket using two of the eight screws provided with the bracket (see Figure 2) and then the
bracket is installed in the structured wiring enclosure by slipping the tabs into the square
holes, and using the push pins in round holes to secure the DA2401.
NOTE: Two of the air holes in each side of DA2401 are threaded to facilitate installation on
the AC1025 bracket.
4. Cat 5e/6 patch cables (available separately) are then connected from an installed switch or
router to the “Data” ports on the 4-Port High Power PoE Injector.
5. The 4 Port High Power PoE Injector is powered with an AC to DC adapter which also needs
to be plugged in to an AC source.
NOTE: If the DA2401 is going to be wall mounted, use the keyhole slots on the rear of the
unit by hanging it on the screws that are first installed in the wall or on a piece of plywood.
