1. Introduction  
MiLAN’s MIL-S801XX switch with a fiber port is a compact desktop size  
switch, which is an ideal solution for many network users. It provides  
wire-speed, Fast Ethernet switching function that allows high-  
performance, low-cost connections.  
Figure 1. The MIL-S801XX  
The MIL-S801XX nine port switch provides 8 switched auto-sensing 10/100  
Mbps RJ-45 Ethernet ports and one 100BASE-FX fiber port.  
The switch combines both 10BASE-T and high-speed 100BASE-TX support  
in one device. The switch automatically senses the speed of the connected  
end device (either 10 or 100 Mbps) and transfers the data at the appropriate  
speed. The MIL-S801 features store-and-forward switching for data and auto-  
learning of addresses which is stored in a 4,000 entry MAC address table.  
The fiber connector on the switch has four different possible options: SC, ST,  
VF-45 and MT-RJ. These connector options are all available in multi-mode  
with a maximum distance of 2 Km. There is one connection option in single-  
mode. The SC connector provided by the fiber distance of 15Km, 40Km and  
60Km.

2. Hardware Description  
This Section mainly describes the hardware of theMIL-S801XX switch. The  
switch is compact (10 inches) with eight 10/100BASE-TX UTP ports plus one  
100BASE-FX fiber port.  
The physical dimensions of the MIL-S801XX switch are: 250mmx 132mmx  
37mm (L 9.8”x W 5.2”x H 1.5”)  
Front Panel  
The Front Panel of theMIL-S801XX switch consists of eight 10/100 UTP  
switch ports (automatic MDI/MDIX), one 100BASE-FX fiber port and one DIP-  
switch to select fiber port for full-duplex or half-duplex mode. The LED  
indicators are also located on the front panel of the switch.

The Front Panel of theMIL-S801XX switch is displayed as above and below.  
There are four types of fiber connectors in multi-mode. These fiber connectors  
are SC, ST, MT-RJ and VF-45. The single-mode version is only available with  
SC connectors.

RJ-45 Ports (Auto MDI/MDIX): Eight auto-sensing for 10BASE-T or  
100BASE-TX connections.  
In general, MDI means connecting to another Hub or switch while MDIX  
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX means  
that you can connect to another switch or workstation without changing  
cabling.  
100BASE-FX Port: There are 4 types of fiber connectors available for the  
MIL-S801XX switch as shown above. The distance for multi-mode fiber  
cabling can be extended up to 2 kilometers. However, the distance for SC  
single-mode fiber port is from 15 to 60 kilometers.  
DIP-switch: the DIP-switch is to select Full-Duplex or Half-Duplex mode for  
fiber port.

Rear Panel  
The 3-pronged power plug is located at the Rear Panel of the 9-Port  
switch as shown in Figure 2-6. The switch will work with AC in the range  
100-240V AC, 50-60Hz.  
Figure 2-6 The Rear Panel of the MIL-S801XX switch  
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.  
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 your 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.  
Figure 2-3. Attaching Rubber Feet to each corner on the bottom of the switch  
Power On  
Connect the power cord to the power socket on the rear panel of the switch. The  
other side of power cord connect 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 supplied.

3.Network Application  
This section provides two samples of network topology in which the switch is  
used. In general, the MIL-S801XX switch is configured for use as a desktop or  
segment switch.  
The MIL-S801XX switch networks PCs, workstations, and servers to each  
other by connecting these devices directly to the switch. It automatically  
learns node address, which are subsequently used to filter and forward all  
traffic based on the destination address.  
Desktop Application  
The MIL-S801XX switchis an ideal solution for small workgroups. The switch  
can be used as a standalone switch to which personal computers, servers,  
and printer servers are directly connected to form a small workgroup.

Segment Application  
Any of the RJ-45 ports on the MIL-S801XX switch can connect with other  
switches or Hubs to interconnect small workgroups to form larger switched  
networks. You can also use fiber ports to connect switches. The distance  
between two switches via fiber cable can be up to 2Km or up to 60Km (SC  
single-mode fiber connector).  
For enterprise networks where large data broadcast are constantly processed,  
this switch is suitable for a department connection to the corporate backbone.  
In the following illustration, two MIL-S801XX switches are used to  
interconnect two small workgroups. All the devices in this network can  
communicate with each other. Connecting servers to the switch allow other  
users to access the server’s data.

4.Trouble Shooting  
This troubleshooting section is intended to help you solve the most  
common problems on the MIL-S801XX switch.  
The switch can be easily monitored through panel indicators to assist in  
identifying problems. This section describes common problems you may  
encounter and where you can find possible solutions.  
Diagnosing LED Indicator  
If the Link indicator does not light up after making a connection, you  
should check the network interface (e.g., a network adapter card on  
the attached device), device to see if it is powered on or defective.  
Be sure the cable is plugged into both the switch and corresponding  
device. Verified the proper cable type is used and its length does not  
exceed specified limits.  
Power  
If the power indicator does turn on when the power cord is plugged  
in, you may have a problem with power outlet, or power cord.  
However, if the switch powers off after running for a while check for  
loose power connections, power losses or surges at power outlet. If  
you still cannot resolve the problem, contact your local dealer for  
assistance.  
Transmission Mode  
Verify that each port is set to the same transmission mode used by  
the attached device (i.e., half or full duplex). The RJ-45 port use  
auto-negotiation to set the transmission mode. If the attached device  
operates at half duplex, which is the default when auto-negotiation  
fails, then it does not have to support auto-negotiation.  
Cabling  
RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair  
(STP) cable for RJ-45 connections: 100O cable for 10Mbps  
connections. See cable specifications on next page. Twisted-pair  
cabling can not exceed 100 meters (328 feet).  
100BASE-FX fiber port: multi-mode must be 62.5/125 um fiber  
cable. You can connect two devices over a 2-kilometer distance with  
multi-mode fiber. Single-mode must use 9/125 um single- mode fiber  
cable. You can connect two devices up to 60- kilometers running full  
duplex.
