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.

All LED status indicators are located on the FRONT panel
of the switches. They provide a real-time indication of
system and operational status. The ports for connections to
other devices and networks are also on the front panels,
along with the crossover switches. The following sections
provide descriptions of the LED indicators and ports.

When a collision occurs on the network
connected to a port, that Full Duplex/Col
indicator blinks.

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.
