Section 1
General Information
Overview
This manual will help you install and maintain the Amphenol Rugged Ethernet Portable
switches. These products are extremely easy to install and operate.
Military applications can now take full advantage of 100Mbps Fast Ethernet performance.
The installation guide describes how to install and use the hardened compact Ethernet
RES-SCE-AC-4US & RES-SCE-AC-8US Military Rugged Switch. Capable of operating
at extreme temperature of -35°C to +75°C and meet the toughest industrial and military
environments such as MIL-STD-810F, MIL-STD-461E up to the highest levels. The
mentioned ability turns the RES-SCE-AC-4US & RES-SCE-AC-8US to the optimal
solutions switch of choice for harsh environments constrained by space.
Developed for military and harsh mobile applications, the switch features mechanical
packaging enhancements designed for MIL-STD-810F airborne and ground environmental
compliance and high reliability. The unit has been especially hardened to improve ingress,
impact, and shock/vibration protection, as well as eliminate all moving parts through
passive cooling, and interface through sealed SCE2 connectors.
Leveraging best-in-class switching technology, the switch serves as a robust solution for
providing local area network (LAN) connectivity to IP-enabled computing and net-centric
devices. Compact in size, the RES-SCE-AC-4US & RES-SCE-AC-8US are particularly
useful for expanding port density to tactical IP routers in space-constrained airborne and
ground vehicle environments.
RES-SCE-AC-4US & RES-SCE-AC-8US are specifically designed for Data Acquisition &
Transmission, Battlefield Communication C4ISR, Rugged Networks, Mobile
Communications, Combat vehicles and Avionic & Shipboard Systems.

Section 2 Hardware
Overview
The switches can be mounted directly to a flat surface or to a wall. Refer to the mechanical
drawing below. Its high protected enclosure makes it able to withstand immersion (IP67/68
rating).
The Ethernet connections come out from rugged SCE2 connectors.
Front Panel
Display The following describes the front panel, and LED indicators of the RES-SCE-AC-4US &
RES-SCE-AC-8US.
LED Indicators
Note: Due to Tactical requirements, LED’s will ONLY operate while pressing and holding
the marked “Push-Button”!
The Single LED indicator on the front panel positioned above the “Push-Button” shows the
operative status of the switch.
Once the LED is turned on, the switch is powered and ready-for-use.
This LED will be on solid yellow/green when proper power (5VDC) has been applied to the
unit.
Above the single “power” LED you will find 8 additional LEDS.
•Each port has a single LEDs indicator that indicates Link / Activity (Off – there is no
link, Steady Green – There is a device connected, Flashing Green – data is being
transmitted)

Section 3 Installation
Selecting a
Site
As with any electronic device, you should place the switch where it will not be subject to
extreme temperatures, humidity, or electromagnetic interference that exceeds the profile of
RES-SCE-AC-4US & RES-SCE-AC-8US. Specifically, the site you select should meet the
following requirements:
•The ambient temperature should be between -35 to 75 degrees Celsius.
•The relative humidity is recommended to be less than 95% percent, non-
condensing.
•Surrounding electrical devices should not exceed the electromagnetic field (RFC)
standards for MIL-STD-461E.
CAPS for
unused
connectors
The switches are pre-equipped with caps on all ports, including power and Ethernet.

Make sure all connectors are protected with cap or sealed plug to ensure sealing
and prevent from deterioration of the contacts.

Section 4 Wiring
Overview
These switches provide connections to Ethernet devices in harsh environment. Typically a
port is used to connect to another Ethernet switch that is connected to the main Ethernet
backbone. The other Ethernet ports are then connected to Ethernet devices such as
communication systems, Ethernet I/O, or industrial computers. Electrical isolation is
provided on the Ethernet ports for increased reliability.
Power wiring
This switch is powered by using port number 1.
Power plug
We suggest using SCE2-B-L1K06-07PN.
Note : pay attention to use the cable’s shield for the ground continuity during the wiring
process.

Guidelines Use data-quality (not voice-quality) twisted pair cable rated category 5e (or better) with
standard RJ45 connectors.
Please note that these cables are available as straight-thru or cross-over configurations.
Either type can be used because these switches support auto-mdi/mdix-crossover. For
reference, the pin-outs of the two cable types are listed below.

Cable Distance
The maximum cable length for 10/100BaseT(x) is typically 100 meters (328 ft.).
Note: Hubs and switches are different devices. Hubs simply broadcast all messages
out all ports. Switches intelligently route messages only out the appropriate port.
