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
1
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.

Hardware Description
Front Panel
The front panel of the Gigabit Ethernet Switch consists of LED Indicators, which
display the conditions of the Gigabit Ethernet Switch and the status of the network.
Figure 2-1. Front Panel view of the MIL-S8000T Gigabit Ethernet Switch
Rear Panel
The rear panel of the Gigabit Ethernet Switch consists of eight Gigabit Ethernet
ports with 10/100/1000Mbps Auto-Negotiation and the DC power connecter.
Power is supplied through an external AC power adapter.

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
100Mbps LED indicators are off.

Hardware Installation
Desktop Installation
Install the MIL-S8000T Gigabit Ethernet Switch in a location that conforms to the
acceptable operation temperature and humidity ranges (see Technical
Specifications). It is recommended that the site be free from strong
electromagnetic source, vibration, dust, and direct sunlight.
A minimum of 10cm of space on the left and right hand side of the Switch is
required for ventilation purposes.
Power On
Connect the power adapter to the power socket on the Gigabit Ethernet Switch.
Connect the other end of the power pack into an appropriate electrical outlet.
Note: Use of a power adapter other than the one supplied with the Gigabit
Ethernet Switch may result in damage to the product.
