switches. These products are extremely easy to install and operate.
Military applications can now take full advantage of 1000Mbps Gigabit Ethernet
performance.
The installation guide describes how to install and use the hardened compact Ethernet
RESMLAC-12EMG-F35 Military Rugged Switch. Capable of operating at extreme
temperature of -45°C to +80°C and meet the toughest industrial and military environments
such as MIL-STD-810F/G/GM, MIL-STD-1275, MIL-STD-461E up to the highest levels.
The mentioned ability turns the RESMLAC-12EMG-F35 to the optimal solutions switch of
choice for harsh environments constrained by space.
Developed for military and harsh mobile applications, the RESMLAC-12EMG-F35
features mechanical packaging enhancements designed for MIL-STD-810F/G/GM 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 MIL-D-38999
circular connectors.
Leveraging best-in-class switching technology, the RESMLAC-12EMG-F35 serves as a
robust solution for providing local area network (LAN) connectivity to IP-enabled
computing and net-centric devices. Compact in size, the RESMLAC-12EMG-F35 is
particularly useful for expanding port density to tactical IP routers in space-constrained
airborne and ground vehicle environments.

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
RESMLAC-12EMG-F35 profile. Specifically, the site you select should meet the following
requirements:
•The ambient temperature should be between -45 to +80 degrees Celsius.
•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.
Mounting
The RESMLAC-12EMG-F35 Ethernet Switch can be fastened to any flat surface by
mounting the box directly. Refer to the mechanical drawings below. Make sure to allow
enough room to route your Ethernet and power cables.
The RESMLAC-12EMG-F35 weighs 1.150 Kg and is mounted via its four # 10-32UNF
Captive Screws.
The overall external dimensions of the RESMLAC-12EMG-F35 are 178(L) x 136(W) x 47(H)
millimeters.

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.
Please follow normal Ethernet wiring practices when installing these switches.
Power wiring
Power is provided to the switch through J1. The switches should be powered using
mating plugs and backshells compliant with MIL-DTL-38999 series III. We suggest using
hereunder accessories. Another backshell can be used but it must ensure a correct sealing
protection.
Power plug
part number
Amphenol designation: TV06 RW 11 35 SN
