The NR4400 currently ships with the following product models:
NR4448:
1.3 Before you Begin Installing the NR4400
Before you begin installing the NR4400 device ensure you have the following accessories or parts
included with your delivery:
•What’s included by default in every NR4400 shipment:
oRack mounng kit (2 x rack ears and 8 x rack screws)
▪You will need a small Philips head screwdriver to aach the screws
o2 x straight through 2m Ethernet cables
o1 x adapter DB9F to RJ45 straight serial
•What is ordered separately or as an add-on:
oAt least one (1) power cord; but ideally two (2)
▪These are sold separately as an accessory. You can purchase them from
Gearlinx (part number 444000) or from your favorite power cable vendor.
▪You can power an NR4400 with only one power cord. The reason there are
two (2) power ports is to provide redundancy of power in the event of a
power issue. When using both power ports it is recommended you power
them from dierent outlets or power sources to improve redundancy.
oDuckfone
▪A Duckfone can be purchased separately or bundled with an NR4400. A
Duckfone provides cellular connecvity (primary or failover) to your NR4400
▪If using a Duckfone you will need an acve data plan and at least one(1) SIM
card. Theis can be purchased directly from Gearlinx or from your favorite
mobile provider.

1.4 Rack Mounng NR4400
You can mount the NR4400 on any standard size, 19-inch (about 49 cm) wide rack. The NR4400
requires 1 rack unit (RU) of space, which is 1.75 inches (44.45 mm) high.
To install the NR4400 into a 19-inch standard chassis:
Step 1. Place one of the supplied rack ears on the side of the NR4400 so that the
four rack holes align with the rack ears and use the supplied screws to secure the
ear to the side of the NR4400.
Step 2. Repeat Step 1 for the other side of the NR4400.
Step 3. Once both brackets are secured the NR4400 is ready to be installed into a
standard 19-inch rack.
