MIL-S2400S

User’s Guide

The MIL-S2400S switch is a twenty four 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

networking. The MIL-S2400S switch has 24 auto-sensing

10/100Base-TX RJ-45 ports with auto MDI/MDIX and features a

"store-and-forward " switching scheme. This allows the switch to

auto-learn and store source address on an 4K-entry MAC address

table. Auto MDI/MDIX allows connection to another switch or work-

station without changing non-crossover or crossover cabling.

• Cabling

RJ-45 ports: Use unshielded twisted-pair (UTP) or shield

twisted-pair (STP) cable for RJ-45 connections:

Category 3, 4 or 5 cable for 10Mbps connections or

Category 5 cable for 100Mbps connections. Also be sure

that the length of any twisted-pair connection does not

exceed 100 meters (328 feet).

Technical Specification

Troubleshooting

This section is intended to help you solve the most common prob-

lems on the MIL-S2400S switch.

Incorrect connections

• 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.

• 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.

• 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.

Hardware Description

Front Panel

The Front Panel of the MIL-S2400S switch consists of 24

10/100Base-TX RJ-45 ports The LED Indicators are also located on

the front panel of the switch.

RJ-45 Ports (Auto MDI/MDIX): 24 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.)

LEDs Indicators

The LED Indicators give real-time information of system operation

status. The following table provides descriptions of LED status and

their meaning.

LED Status Description

Power Green Power On

Off Power is not connected

LK/ACT Green The port is connected with

operating device.

Blinks The port is receiving or

transmitting data.

Off No device attached.

Rear Panel

The 3-pronged power plug is located at the rear Panel of the MIL-

S2400S switch as shown below. The switch will work with AC in the

range 100-240V AC, 50-60Hz

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

allow air circulation.

Power ON

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 with a power cord.

Check the power indicator on the front panel to see if power is prop-

erly supplied.
