Chapter 1 Introduction  
MIL-S1000 switches are multi-speed network devices  
combining Ethernet, Fast Ethernet and Gigabit Ethernet  
capabilities in a single compact, rack-mountable cabinet.  
Combining 10Mbps Ethernet, 100Mbps Fast Ethernet and  
Gigabit Ethernet interfaces in one unit allows these  
switches to unclog existing LANs and provide a path to  
efficient, high-speed networking.  
The MIL-S1000 switch is a combination of a 4-slot host  
cabinet which accepts 4 different media modules and One  
RS-232 port for SNMP(Optional). A maximum configuration  
of 32 x 10/100Base-Tx switched ports can be achieved  
using 4×8 port 10/100Base-Tx modules. In the same way,  
a maximum configuration of 32×10/100Base-TX or  
16×100Base-FX ports or 4x 1000Base-SX can be  
accommodated in the host cabling. Any of the above  
modules can be integrated to give up to many different  
configurations.

Chapter 2 Planning your Network  
Before you install your MIL-S1000, you should review the  
guidelines for setting up Ethernet networks. Further, you  
should plan your network to take maximum advantage of  
its switching capabilities.  
10Base-T Ethernet Network Guidelines  
# The maximum length of a 10Base-T cable segment is  
100 meters (328 feet).  
# The maximum number of nodes on a 10Base-T  
segment is one (1) for regular 10Base-T.  
# The recommended cable type is EIA/TIA Category 3 or  
higher.  
# The maximum network diameter is 500 meters (1,640  
feet) for Ethernet networks.  
# The maximum number of segments between any two  
nodes in the network is five.  
# The maximum number of hubs or repeaters between  
any two nodes in the network is four.  
 
100Base-TX Ethernet Network Guidelines  
# The maximum length of a 100Base-TX cable segment  
is 100 meters (328 feet).  
# The maximum number of hubs on a 100Base-TX  
segment is one if using Class I hubs and two if using  
Class II hubs.  
# The recommended cable type is EIA/TIA Category 5  
unshielded twisted-pair.  
# The maximum network diameter is 200 meters (656  
feet) when using Class I hubs and 205 meters (672.5  
feet) when using Class II hubs.  
100BASE-FX Network Guidelines  
# In half duplex mode, the fiber optic segment cannot  
exceed 412m (1,135ft) in length.  
# In full duplex mode, the fiber optic segment cannot  
exceed 2km (6562 ft) in length.  
 
1000BASE-SX and LX Network Guideline  
1000BASE-SX  
# In multi-mode, the fiber optic segment cannot exceed  
220m(62.5/125µm) or 500m(50/125µm) in length.  
1000BASE-LX  
# In multi-mode, the fiber optic segment cannot exceed  
550m(62.5/125µm), 550m(50/125µm) in length.  
# In single-mode the fiber optic segment cannot exceed  
10km(9/125µm).  
Network Planning  
Using a switch, such as a MIL-S1000, can expand network  
topologies and enhance network performance.  
Each port on a switch connects to a separate network with  
its own collision domain. Separating networks with these  
switches allows you to expand 10Base-T networks past the  
four-hub limit and expand 100Base-TX networks past the  
one or two hub limit.  
These switches also filter incoming traffic. On standard  
hubs and repeaters, any data received on a port is  
forwarded to all of the other ports. On switches, data  
received on one port is forwarded only to the port of the  
destination device, and if the traffic is local, the data is not  
forwarded at all. Also, switches can forward multiple data  
transaction at once.  
 
To expand your network topology or enhance network  
performance, use the MIL-S1000 as collapsed backbone or  
to increase file server performance, to segment large  
networks, to interconnect 10Mbps networks with 100Mbps  
networks, or to overcome the limitations of 10Base-T and  
100Base-TX networks.  
Expanded Networks  
You can expand your 10Base-T or 100Base-TX or  
1000Base-SX/LX network beyond its hub limit by adding a  
MIL-S1000.  
10Base-T Networks  
10Base-T Networks are limited to four hubs between any  
two nodes. By adding your MIL-S1000 to a network, you  
can divide that network into segments with their own  
collision domains. In other words, you can connect one  
10Base-T network with four hubs to your MIL-S1000. Then  
you can connect another 10Base-T network with four hubs  
to your MIL-S1000. You will then have one network with  
two collision domains, allowing four hubs on each port.  
Figure 2-1. Expanding your 10Base-T Network  
 
100Base-TX Networks  
The hub limit of a 100Base-TX network depends on the  
class of the hub in the network. With a Class I hub, the  
network is limited to one hub. With a Class II hub, the  
network is limited to two hubs.  
However, you can expand your 100Base-TX network that  
includes either class of hub by adding a MIL-S1000. With  
the MIL-S1000 added to your 100Base-TX network, you  
can separate that network into individual segments with  
their own collision domains. In other words, you can  
connect one 100Base-T network with one or two hubs to  
the MIL-S1000, and you can connect another 100Base-TX  
network with one or two hubs to the MIL-S1000. You will  
then have one network with two collision domains.  
Figure 2-2. Expanding your 100Base-TX network (Class I)  
 
Collapsed Backbone Link  
Traditionally, bridges and routers have been used to link  
local area networks into one interconnected network. But  
these devices involve difficult management and long traffic  
delays.  
The MIL-S1000 providers multiport bridges with short  
delays, easy setup and maintenance, making it ideal for  
backbone links. Also, the Built-in filtering on this hub  
deceases network traffic, while the multiple ports that  
communicate  
performance.  
simultaneously  
increases  
network  
One or more of your hub's 100Mbps or 1000Mbps ports  
can be used as a high-speed backbone link to other hubs  
serving as collapsed backbones.  
 
Figure 2-3. MIL-S1000 100/1000 Hub in a collapsed backbone  
link  
Fileserver Link  
100Base Solution  
With a fileserver link, you can increase file server  
performance by increasing the Hub's bandwidth between  
one or more fileservers and the workgroups they serve.  
If you connect 10Mbps workgroup hubs to the 10Mbps  
ports on the MIL-S1000, traffic in one workgroup will not  
interfere with the performance of another workgroup.  
 
Figure 2-4. Fileserver Link  
Connecting servers through 100Base-TX ports increases  
performance to the clients, even if the clients are on  
10Base-T segments.  
Because multiple 10Base-T devices can access the file  
server at the same time through a 100Base-TX connection,  
performance increases to beyond the performance of  
standard 10Base-T or 100Base-TX hubs. Operating the  
MIL-S1000 at full duplex further increases performance  
 
1000Base Solution  
You can upgrade your server with a Gigabit Ethernet NIC,  
and introduce a Gigabit backbone switch too.  
This  
contains several switch ports which provides much faster  
access to your server with minimum disruption. See Figure  
16.  
Multiport Bridge with High-Bandwidth Backbone  
With a MIL-S1000, you can divide large network to ease  
congestion, and connect 10Base-T networks to 100Base-  
TX or 100Base to 1000Base networks for more flexibility.  
Adding your MIL-S1000 to a large network creates more  
segments in that network. The MIL-S1000 built-in filtering  
function separates a segment's local traffic from network  
traffic, reducing the amount of network traffic and easing  
congestion.  
 
Figure 2-5. Used as a Multiport Bridge  
Using your hub, you can also connect 10Base-T networks  
and 100Base-TX and 1000Base-SX/LX networks together  
for more flexibility in your network topology. As in the  
Figure 16 shown above, the MIL-S1000 can connect  
through one port to a 10Base-T network, and through  
another port, connect to a 100Base-TX port, creating one  
network. This switch can also connect to a 1000Base-LX or  
SX port.  
 
Chapter 3 Installation  
The MIL-S1000 can be installed quickly and easily.  
However, for an installation with minimum impact on  
the existing network, please read this chapter carefully.  
Installing a MIL-S1000 involves three steps:  
1. Choosing a location  
2. Supplying power  
3. Connecting the switch  
Choosing A Location  
The location of the switch is based on the following criteria:  
" Avoid dusty locations.  
" Avoid electromagnetic noisy areas, such as locations  
close to power transformers or radio transmitters.  
" Avoid temperatures below 32 Degrees Fahrenheit and  
over 122 Degrees Fahrenheit.  
" Allow a clear view of the front panel LED indicators.  
" Allow easy access to the front panel ports and the rear  
panel switches.  
After choosing an appropriate location, you can install the  
 
switch on a desktop or in a rack.  
Figure 3-1. Attaching self-adhesive feet for desktop installation  
Rack Installation  
Your switch comes with two rack mounting brackets. you  
can use these brackets to mount the switch on an EIA  
standard 19" rack. Attach the brackets to the switch, using  
the screws provided.  
Figure 3-2. Attaching the mount brackets for rack installation  
Next, install the switch in the rack using the screws  
provided to attach the brackets to the rack.  
Supplying Power  
 
The MIL-S1000 switch is equipped with a universal  
switching power supply that accepts AC input voltages  
from 100 to 240VAC and 50 to 60 Hz.  
To supply power to your switch:  
1. Plug the connector of the power cord into the power port  
on the rear panel of your switch.  
2. Plug the other end of the power cord into an AC wall  
outlet.  
3. Set the power switch to ON and verify that the Power  
LED is lit. If it is not, check the following:  
" The power switch is in the ON position.  
" The power cord is properly connected to the wall  
outlet and to the power connection on the switch.  
" The wall outlet is functional.  
Note: Network cable segments can be connected or  
disconnected from the switch while the power is on, without  
interrupting the operation of the switch.  
 
Connecting the Switch  
You can connect your switch to network devices such as  
desktops and workgroups or to other hubs.  
Before connecting your switch to a desktop or workgroup  
make sure that:  
# The 10Base-T twisted pair Ethernet cabling is Category  
3 or above.  
# The 100Base-TX Fast Ethernet cabling is tested  
Category 5.  
# The 100Base-FX fiber cabling is 62.5/125 micron multi-  
mode fiber.  
# The 1000Base-SX/LX fiber cabling is 50/125, 62.5/125  
micron multi-mode or 9/125 micron single-mode fiber.  
 
Chapter 4. Module Installation and Removal  
WARNING  
Before installing the Modules into a MIL-S1000, you must  
disconnect the Switch from the main power supply.  
Handling the Modules  
The Module can be easily damaged by electrostatic  
discharge. To prevent damage, please observe the  
following:  
# Do not remove Modules from their packaging until you  
are ready to install it into a Switch.  
# Do not touch any of the pins, connections or  
components on the Modules.  
# Handle the Modules only by its edges and front panel.  
# Always wear an anti-static wristband connected to a  
suitable grounding point.  
# Always store or transport Modules in appropriate anti-  
static packaging.  
 
Module Setup and Installation  
1. Ensure that the Switch is disconnected from the main  
power supply and that you are wearing an anti-static  
wrist-band connected to a suitable grounding point.  
2. Place the Switch on a flat surface. Using a small cross-  
bladed screwdriver, remove the blanking plate from the  
rear of the Switch. Do not remove any other screws from  
the rear of the Switch.  
3. Keep the blanking plate and screws in a safe place. If  
you remove the Module at any time, you must replace  
the blanking plate to prevent dust and debris from  
entering the Switch and to aid the circulation of cooling  
air.  
4. Hold the Module so that the text on the front panel is  
oriented correctly, and insert it into the Switch, ensuring  
the connectors are fully engaged. Tighten the two  
captive thumbscrews that secure the Module in place.

Appendix B. Pin Assignments  
RJ-45 station ports can be attached to any device which  
use a standard network interface (e.g., a workstation,  
server, bridge or router). RJ-45 daisy-chain ports can be  
cascaded to a station port on similar networking devices  
(e.g., another switch or hub). Use unshielded twisted-pair  
(UTP) for RJ-45 connections: 100 ohm Category 3,4 or 5  
cable for 10Mbps connections or 100 ohm Category 5  
cable for 100Mbps connections. Also be sure that the  
length of any twisted-pair connection does not exceed 100  
meters (328 feet).
