1.2 Installation
The DA1458 8-Port GigE 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 5/6 should be run in the walls from the structured wiring enclosure
location in the home where the DA1458 will be installed to each location in the home where an
Ethernet networking interface is needed and/or an IEEE 802.3af device will be installed (leave
extra cable at both ends).
NOTE: Run the Cat 5/6
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 Ethernet interface
device or IEEE 802.3af device for recommended use of electrical gang boxes or low voltage
brackets, with the extra Cat 5/6 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 5/6 cable that was secured at each of the locations should be pulled out and terminated
with an RJ45 plug (or insert as required) following standard TIA 568A recommendations and if
PoE is required, attached with a Cat 5/6 jumper to the IEEE 802.3af device which is then
installed.
2.
In the structured wiring enclosure the Cat 5/6 cables from the remote locations are terminated
with RJ45 plugs for direct connection to the DA1458
“Data or Data +Power” RJ45 jacks once
the DA1458 is installed.
3.
The DA1458 is attached to the tw0-bay bracket with push pins in each corner, 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 DA1458 assembly.
4.
If a router is installed in the enclosure, use a Cat 5/6 patch cable (available separately) to
connect from a router port to one of the
“Data or Data + Power” ports on the DA1458 (see
Figure 3
).
5.
The DA1458 is powered with an AC to DC adapter which also needs to be plugged in to an AC
source.
