MIL-S1600S
User’s Guide
The MIL-S1600S switch is a sixteen port switch that can be used to
build high-performance switched workgroup networks. This switch is
a store-and-forward device that offers low latency for high-speed net-
working. The MIL-S1600S switch has 16 auto-sensing 10/100Base-
TX RJ-45 ports with auto MDI/MDIX and features a "store-and-for-
ward " switching scheme. This allows the switch to auto-learn and
store source address on an 8K-entry MAC address table. Auto
MDI/MDIX allows connection to another switch or workstation without
changing non-crossover or crossover cabling.

Troubleshooting
Features
• Conforms to 802.3, 802.3u, and 802.3x standard.
• 16 auto-sensing 10/100Mbps Ethernet RJ-45 ports.
• Automatic MDI/MDIX crossover for 10Base-T and 100Base-TX
ports.
This section is intended to help you solve the most common prob-
lems on the MIL-S1600S switch.
Incorrect connections
• Auto-negotiation supported.
• Back-Pressure-Base flow control on Half-duplex ports.
• Pause-Frame-Base flow control on Full-duplex ports.
• Store-and-forwarding switching architecture for abnormal packet fil-
tering.
• Faulty or loose cables
Look for loose or obviously faulty connections. If they
appear to be OK, make sure the connections are snug. If
that does not correct the problem, try a different cable.
• Full wire speed forwarding rate.
• 8K-entry MAC address table.
• LED-indicators for Power, Link/Active.
• Non-standard cables
Non-standard and miswired cables may cause numerous
network collisions and other network problem, and can
seriously impair network performance. A category 5 cable
tester is a recommended tool for every 100Base-T network
installation.
Package Contents
Unpack the contents of the MIL-S1600S switch and verify them
against the checklist below.
• Improper Network Topologies
It is important to make sure that you have a valid network
topology. You should make sure that your network topolo-
gy contains no data path loops. Between any two-end
nodes, there should be only one active cabling path at any
time. Data path loops will cause broadcast storms that will
severely impact your network performance.

Diagnosing LED Indicators
The switch can be easily monitored through panel indicators to assist
in identifying problems, which describes common problems you may
encounter and where you can find possible solutions.
If the power indicator does not turn on when the power cord is
plugged in, you may have a problem with power cord. 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.
Compare the contents of your MIL-S1600S switch package with the
standard checklist above. If any item is missing or damaged, please
contact your local dealer for service.

Rear Panel
Hardware Description
The 3-pronged power plug is located at the rear Panel of the MIL-
S1600S switch as shown in Figure 2-2. The switch will work with AC
in the range 100-240V AC, 50-60Hz
Front Panel
The Front Panel of the MIL-S1600S switch consists of 16
10/100Base-TX RJ-45 ports The LED Indicators are also located on
the front panel of the switch.
Desktop Installation
RJ-45 Ports (Auto MDI/MDIX): 16 10/100 auto-sensing for
10Base-T or 100Base-TX connections. (In general, MDI means con-
necting 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 non-
crossover or crossover cabling.)
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
allow air circulation.

LEDs Indicators
The LED Indicators gives real-time information of systematic opera-
tion status. The following table provides descriptions of LED status
and their meaning.
Connect the power cord to the power socket on the rear panel of the
switch. The internal power supply in the switch works with AC in the
voltage range 100-240VAC, frequency 50~60Hz.
