1. Introduction
Gigabit Ethernet over copper technology is a cost-effective way for
network equipment to be upgraded from Fast Ethernet to Gigabit speeds
without the use of expensive fiber optics cabling. Gigabit networks create
high-speed backbone connections between switches, servers, databases
and end stations.
The MIL-S8000G, an 8-Port Gigabit switch, is an ideal solution for solving
traffic block at the core of the network. It offers eight auto-negotiation
10/100/1000Base-T Gigabit Ethernet ports that can significantly improve
your network’s backbone performance. The switch will fit into any level
network to act as an exit to the backbone switch that can handle
throughput speeds up to 2000Mbps at Full-duplex mode.
Figure 1-1. MIL-S8000G
The switch will automatically detect the speed of the device that you plug
into it to allow connections to 10, 100 or 1000Mbps devices.
The eight port Gigabit switch features automatic MDI/MDIX connections
for each port. It also features store-and-forward switching and autolearning of source addresses with an 8,000 entry MAC address table.
Conforms to IEEE 802.3, 802.3u, 802.3ab and 802.3x standards
Eight auto-negotiation 10/100/1000Base-TX switch ports (Using
shielded RJ-45 connections)

Front Panel
The Front Panel of the 8-Port Gigabit Switch consists of eight autonegotiation 10/100/1000Mbps Ethernet RJ-45 connectors, supporting
automatic MDI/MDIX, and four LED-indicators (1000M, 100M, LK/ACT,
FUL/COL) for each Gigabit port.

3. Installation
Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby.
The surface should be clean, smooth, level, and sturdy.
Make sure there is enough clearance around the switch to allow
attachment of cables, power cord and air circulation.
Attaching Rubber Feet
A. Make sure mounting surface on the bottom of the switch is grease
and dust free.
B. Remove adhesive backing from the rubber feet.
Figure 3-1. Attaching rubber feet to each corner on the bottom of the
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-S8000G includes a rack-mounted kit that allows it to be mounted
in an EIA standard size, 19-inch Rack.
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-S8000G
switch 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. Mounting the MIL-S8000G 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. The other side of power cord connects to the power outlet. The
internal power supply in the Switch works with AC in the voltage range
100-240VAC, frequency 50~60Hz.
Check the power indicator on the front panel to see if power is properly
4. Network Application
The MIL-S8000G Switch can be used connect servers, switches,
workstations, and PCs (a Gigabit 1000Base-T NIC is required for PC
installation) to each other by connecting these devices directly to the
Switch. The Switch automatically learns node addresses, which are used
to filter and forward all traffic, based on the destination address.
Backbone Switch
The MIL-S8000G Switch is an ideal solution for enterprise networks
where large data broadcasts are constantly processed.
All ports can be connected to departmental switches, and the
departmental switches can be connected to the MIL-S8000G Switch.
Each end station can access the server’s data by connecting the servers
to the core switch. This will allow all the devices in the network to
communicate with each other.
Workgroup A
Workgroup B
Figure 4-1. An example of a network connection, with the MIL-S8000G
Switch acting as the core switch.
This switch is an ideal solution for backbone connectivity. In the above
example, servers, department switches, and workstations are directly
connected to the core switch, the MIL-S8000G Switch.
5. Network Configuration
The Console port is a female DB-9 connector that enables a connection
to a PC or terminal for monitoring and configuring the MIL-S8000G
Switch. Use the supplied RS-232 cable with a male DB-9 connector to
connect a terminal or PC to the Console port.
The Console configuration allows the switch to be set to enable a user at
a remote console terminal to communicate with the MIL-S8000G Switch
as if the console terminal were directly connected to it.
Figure 5-1. Connecting the MIL-S8000G Switch to a terminal via RS232 cable.
Login to the Console Interface
When the connection between Switch and PC is finished, turn on the PC
and run a terminal emulation program or Hyper Terminal. Configure the
communication parameters to match the following default characteristics
of the console port:
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Control flow: None

and enter the appropriate value in the Flow Control field.
5.3 Mirror Configuration

Figure 5-6. The Device Configuration Setup menu
By enabling port mirroring, the source port will be forwarded to the target
port. Select either Enable or Disable by using the <Backspace> key.
5.4 VLAN Configuration
Figure 5-7. The VLAN Configuration menu
Assigning physical ports within a work group is a simple and common
method of defining a virtual work group – VLAN. It delivers the benefit of
broadcast control and simplifies configuration for the network manager.
One advantage of the Port-Based VLAN is its simplicity and ease of
configuration. Limited security, however, is its drawback – anyone can
plug into the port and gain access to the VLAN.
5.5 VLAN Setup
Figure 5-8. The VLAN Setup menu
Select the VLAN entry to Enable or Disable the VLAN group. Use the
<Backspace> key to Enable (add) or Disable (remove) ports in the VLAN
5.6 Trunk Configuration
Figure 5-9. The Trunk Configuration menu
Multiple links between switches can be grouped or trunked to work as
one virtual, aggregate link. Each trunk can hold up to 2 ports. Only ports
of the same speed can belong to a single trunk.
5.7 Miscellaneous Configuration

Select each port to change the status, toggle the Enable / Disable field
and enter the appropriate value in the Aging Time field.
6. Troubleshooting
This troubleshooting section is intended to help solve many common
problems that might occur when installing the MIL-S8000G. The switch
can be easily monitored through panel indicators to assist in identifying
„ Power
If the power indicator does not light up when the power cord is
plugged in, you may have a problem with the power outlet or power
cord. However, if the switch powers off after running for awhile,
check for loose power connections, power losses or surges at the
power outlet. If you still cannot resolve the problem, contact your
local dealer for assistance.
„ Diagnostic LED Indicator
1. If the link indicator does not light up after making a connection,
check whether the network interface (e.g., a network adapter
card on the attached device), network cable, or switch port is
defective or not.
2. Verify that the switch and attached device are powered on.
3. Be sure the cable is plugged into both the switch and the
corresponding device.
4. Verify that the proper cable type is used and its length does not
exceed specified limits (100 meters).
Transmission Mode
Verify that each port is set to the same transmission mode used by
the attached device, for example Half or Full-Duplex. The RJ-45
ports use auto-negotiation to set the transmission mode. If the
attached devices do not support auto-negotiation, the switch will
assume the port operates at half duplex.
RJ-45 ports: Use unshielded twisted-pair (UTP) or shielded and
twisted pair (STP) cable for RJ-45 connections: 100Ω 2-pair
UTP/STP Category 3, 4 or 5 cable for 10Mbps connections or 2-pair
UTP/STP 100Ω Category 5 cable for 100Mbps connections and 4pair UTP/STP Category 5 cable for Gigabit 1000Mbps connections.
Also be sure that the length of any twisted-pair connection does not
exceed 100 meters (328 feet).
