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.

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.

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
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

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

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.

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.

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).
