Introduction
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet
structure, format, and support for CSMA/CD protocol, full duplex, flow control, and
management objects, but with a tenfold increase in theoretical throughput over
100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet.
Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments,
Gigabit Ethernet provides a straightforward upgrade without wasting a company’s
existing investment in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet are
essential to coping with the network bottlenecks that frequently develop as
computers and their busses get faster and user applications generate more traffic.
Upgrading key components, such as your backbone and servers to Gigabit
Ethernet can greatly improve network response times, as well as significantly
speed up the traffic between your subnets.
Gigabit Ethernet supports video conferencing, complex imaging, and similar
data-intensive applications. Likewise, since data transfers occur 10 times faster
than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to
perform 10 times the number of operations in the same amount of time.
Switching Technology
Another key development pushing the limits of Ethernet technology is in the field
of switching technology. A switch bridges Ethernet packets at the MAC address
level of the Ethernet protocol transmitting among connected Ethernet or fast
Ethernet LAN segments.
Switching is a cost-effective way of increasing the total network capacity available

to users on a local area network. A switch increases capacity and decreases
network loading by making it possible for a local area network to be divided into
different segments which do not compete with each other for network transmission
capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between the individual segments.
The switch automatically forwards traffic that needs to go from one segment to
another, without interfering with any other segments. This allows the total network
capacity to be multiplied, while still maintaining the same network cabling and
adapter cards.
Switching LAN technology is a marked improvement over the previous generation
of network bridges, which were characterized by higher latencies. Routers have
also been used to segment local area networks, but the cost of a router and the
setup and maintenance required make routers relatively impractical. Today’s
switches are an ideal solution to most kinds of local area network congestion
problems.
Features
The MIL-S1600T Gigabit Ethernet Switch was designed for easy installation and
high performance in an environment where traffic on the network and the number
of users increase continuously.

Hardware Description
Front Panel
The front panel of the Gigabit Ethernet Switch consists of 16 1000BASE-T Gigabit
Ethernet ports and the LED Indicators for the unit, which displays the conditions of
the Gigabit Ethernet Switch and the status of the network.
Figure 2-1. Front Panel view of the MIL-S16000T Gigabit Ethernet Switch
Rear Panel
The rear panel of the Gigabit Ethernet Switch consists of an AC power connecter
and a power switch.
Figure 2-2. Rear Panel view of the MIL-S16000T Gigabit Ethernet Switch
The AC Power Connector is a three-pronged connector that supports the power
cord. Plug the female connector of the provided power cord into this connector, and
the male into a power outlet. Supported input voltages range from 100 - 240 VAC
at 50/60 Hz.

LED Indicators
The LED indicators of the Gigabit Ethernet Switch provide a real-time indication of
system operating statuses. There are three LED-indicators for each Gigabit
Ethernet port and one Power LED for the Unit.

POWER
The Power LED indicator is solid green when the Gigabit Ethernet Switch is
receiving power.
Link/Act
The Link/Act LED indicators are solid when there is a secure connection (or link)
to the desired port. A blinking LED indicator signifies reception or transmission (i.e.
Activity—Act) of data occurring on a port.
1000Mbps
The 1000Mbps LED indicators are solid when there is a secure connection (or link)
to a 1000Mbps Gigabit Ethernet device at the desired port.
100Mbps
The 100Mbps LED indicators are solid when there is a secure connection (or link)
to a 100Mbps Fast Ethernet device at the desired port.
When the connection (or link) is 10Mbps, both the 1000Mbps and
Note:
100Mbps LED indicators are off.

Hardware Installation
Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby. The
surface where you put your switch should be clean, smooth, level, and sturdy.
Provide enough clearance around the switch to allow attachment of cables, power
cord and air circulation.
Attaching Rubber Feet
A. Make sure the mounting surface on the bottom of the Switch is grease and
dust free.
B. Remove adhesive backing from the rubber feet.
C. Apply the rubber feet to each corner on the bottom of the switch.
These footpads can prevent the Switch from shock/vibration.

Rack-mounted Installation
The MIL-S16000T comes with a rack-mounted kit and can be mounted in an EIA
standard size, 19-inch rack. The Switch can be placed in a wiring closet with other
equipment.
Perform the following steps to rack mount the switch:
A. Position one bracket to align with the holes on one side of the switch and
secure it with the smaller bracket screws. Then attach the remaining bracket
to the other side of the Switch.
Figure 3-2. Attach mounting brackets with screws
B. After attaching both mounting brackets, position the MIL-S16000T in the rack
by lining up the holes in the brackets with the appropriate holes on the rack.
Secure the Switch to the rack with a screwdriver and the rack-mounting
screws.
Figure 3-3. Mount the MIL-S16000T in an EIA standard 19-inch Rack
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance on the
front and 3.4 inches (8 cm) on the back of the Switch. This is especially important
for enclosed rack installation.

Power On
Connect the power cord to the power socket on the rear panel of the Switch.
Connect the other end of the cord to an appropriate power outlet. Press the power
On/Off switch to the on position and check the power indicator on the front panel
to see if power is properly supplied.
