jurisdiction. Refer to section 1 for other important installation warnings.
FCC Statement
- This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures: Reorient or relocate the receiving
antenna; Increase the separation between the equipment and receiver; Connect the equipment into an
outlet on a circuit different from that to which the receiver is connected; Consult the dealer or an
experienced radio/TV technician for help.

General Specifications
The Sixnet MIL312-1 is a 12 port industrial Ethernet managed switch designed to meet the
extreme requirements found in the toughest applications. It combines the high performance
and security of an enterprise-class switch with rugged packaging and protected circuitry to
meet the needs of the most demanding applications.
This manual will help you install and maintain these industrial Ethernet switches.
Installation of these switches is very easy and they will begin to operate as soon as they
are powered up. Though these are fully managed switches, they will act as unmanaged
until they are configured otherwise. Refer to the separate software manual or management
guide for configuration of the advanced networking functionality and security.
Note: This manual only covers the installation and wiring of these switches. Refer
to the separate Software User Manual for details on configuring and using any of
the management functions such as SNMP, RSTP, IGMP, port mirroring, etc.
Unlike an Ethernet hub that broadcasts all messages out all ports, these industrial Ethernet
switches will intelligently route Ethernet messages only out the appropriate port. The major
benefits of this are increased bandwidth and speed, reduction or elimination of message
collisions, and deterministic performance when tied with real-time systems.
These switches support 10BaseT (10 Mbps), 100BaseT (100 Mbps) and 1000BaseT (1000
Mbps) on 12 ports. Each of these ports independently and automatically senses the speed
and duplex for best performance. They also offer auto-crossover and auto-polarity to
assure a proper link with either straight or crossed wired cables or even when the cable is
incorrectly wired.
The switch has the following performance specifications. Note: All specifications are
subject to change. Consult factory for latest information.

Status LED
Power LEDs

LEDs
LED Blackout
The switch has a set of LEDs to indicate the status of various operating conditions as
defined below.
The Status LED indicates the overall health of the switch. It is normally ON solid green
indicating that no internal CPU or software problems are detected. It will flash green when
loading firmware and briefly on power up or reset. Otherwise, if it is OFF or amber for an
extended period of time then a problem is detected. In this case, please contact technical
support.
The Power LED will be on solid green when power is applied to the switch. In the event of a
power fault, the LED will turn to solid amber. The LED will also be solid amber during a
portion of the boot up sequence.
The switch has a set of LEDs to indicate the status of the Ethernet ports. Each LED is
labeled with the number of the port it represents. They function as follows:
Solid Green = 1000 Mbps linked detected but no Ethernet activity.
Flashing Green = 1000 Mbps linked detected with Ethernet activity.
Solid Orange = 10/100 Mbps linked but no Ethernet activity.
Flashing Orange = 10/100 Mbps linked detected with Ethernet activity.
OFF = No link detected.
The switch is equipped with the capability to toggle the LEDs from an active state to an
inactive state. See Console Receptacle Pinout above or refer to data sheet for more
information.

Vent
Without a pressure ventilation system the pressure differential that can occur due to
temperature or altitude changes can result in condensation. To prevent this, the switch
incorporates a pressure vent that adjusts the internal air pressure to match the
surrounding (external) pressure. At the same time the vent is IP67 rated and will not let
moisture into the switch. Assembled

Product
Support
We sincerely hope that you never experience a problem with any
need service, call Sixnet at (518) 877-5173 and ask for Technical Support. A trained
specialist will help you to quickly determine the source of the problem. Many problems are
easily resolved with a single phone call. If it is necessary to return a unit to us, an RMA
(Return Material Authorization) number will be given to you.
Sixnet tracks the flow of returned material with our RMA system to ensure speedy service.
You must include this RMA number on the outside of the box so that your return can be
processed immediately.
The applications engineer you are speaking with will fill out an RMA request for you. If the
unit has a serial number, we will not need detailed financial information. Otherwise, be sure
to have your original purchase order number and date purchased available.
We suggest that you give us a repair purchase order number in case the repair is not
covered under our warranty. You will not be billed if the repair is covered under warranty.
Please supply us with as many details about the problem as you can. The information you
supply will be written on the RMA form and supplied to the repair department before your
unit arrives. This helps us to provide you with the best service, in the fastest manner.
Normally, repairs are completed in two days. Sometimes difficult problems take a little
