Chapter 2: Overview
2. Overview
2.1 Description
The WRT4000 Series Router provides speed, capacity, and flexibility for wired, optical fiber, and cellular uplinks; complete remote
management; and support for current and legacy data protocols.
The WRT4000 Series Router chassis is designed to operate in industrial or commercial environments with a wide range of
ambient temperatures. The industrial versions have a tight all-metal enclosure that resists dust, moisture, and electromagnetic
interference (EMI). The commercial versions have a plastic enclosure that resists dust, moisture, and EMI.
The WRT4000 Series Router has expanded memory and a high-speed processor that allow it to handle multiple ports and high-
speed network connections while converting protocols, routing packets, and applying firewall rules and other security measures.
With an optional encryption-chip module, a single WRT4000 Series Router can terminate more than 1,000 virtual private
network (VPN) tunnels without affecting other features. One internal cellular wireless module is standard on the industrial and
commercial routers (all part numbers). The industrial routers (part numbers WRT4001A–WRT4004A and WRT4001A-DC–
WRT4004A-DC) also have a dual-port serial expansion module installed in one of the expansion slots.
Up to two antennas handle 3G/4G/LTE cellular and advanced Wi-Fi.
There is no cooling fan or other moving parts. All models are built on the same hardware platform.
The WRT4000 Series Router requires minimal power. Typical configurations draw less than 13 W. The power source options are:
• an AC power supply unit (PSU)
• a DC input line, at several voltages
The power input sources provide 5 VDC to the chassis.
NOTE: A DC power input can form a redundant pair with an AC power input: One is the chassis’s primary input power source,
and the other source provides power if the primary source is down.
