Introduction

Ethernet Switching Technology

Ethernet Switching Technology dramatically increases the total bandwidth of a network, eliminates congestion problems inherent with ( CSMA/CD ) protocol, which greatly reduces unnecessary transmissions.

Switch Technology has revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port ( Full-duplex ), which essentially doubled the bandwidth. Second, by reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing.

Third, by using the store-and-forward technology’s approach of inspecting each packet to prevent transmitting corrupt or redundant data, switching eliminates unnecessary transmission. By employing address-learning, the switch only transfers data to the port it is destined for.

Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices.

Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss of data. Autonegotiation and flow-control may require disablement for some networking operations involves legacy equipment. Disabling the auto-negotiation is accomplished by configuring the speed or duplex of a port.

Ethernet Switching Technology supplies higher performance at costs lower than legacy solutions. Wider bandwidth, no congestion, and the reduction in traffic are the many reasons why switching is replacing expensive routers and inefficient hubs for the ultimate networking solution. Switching brings a whole new way of thinking to networking.

The MIL-S2400 and MIL-S1600 Switches are multi-port Switches that can be used to build highperformance switched workgroup networks. These switches are store-and-forward devices that offer low latency for high-speed networking. They are targeted at workgroup, department or backbone computing environment at SME ( small, medium enterprise ) businesses.

Figure 1-1. The MIL-S2400 and MIL-S1600 Switch ( Auto MDI/MDIX )

The MIL-S2400 and MIL-S1600 Switches feature a “store-and-forward “ switching scheme. This allows the switch to auto-learn and store source address on an 4K-entry MAC address table.

The MIL-S2400 and MIL-S1600 Switches have 16/24 auto-sensing 10/100Base-TX RJ-45 ports plus one extension slot for ( Optional ) 100Base-FX fiber module enables long-distance connection. The optional modules support MT-RJ, SC single-mode, ST, MT-RJ, VF-45 multi-mode connectors. The fiber port can be used to connect to a remote side up to 2 Km ( multi-mode ) or 60Km ( single-mode ).

Installing 100Base-FX Module

The optional 100Base-FX Modules are designed to be inserted in the extension slot. Before installation, ensure that the power is disconnected. The module is NOT hot-swappable. Follow the steps below to install the optional 100Base-FX Module:

1. Power the MIL-S2400 and MIL-S1600 Switches OFF before installing the 100Base-FX

Module.

2. Unscrew the thumbscrews on the blank bracket. Remove the blank bracket and set aside, but do not discard it. Replace the blank bracket if you should remove the fiber module.

3. Install the new 100Base-FX Module by inserting it into the guides and sliding it in until it stops

( See Figure 3-7 ). Press it firmly until you feel the module snap into place. Never force, twist or bend the 100Base-FX Module.

Figure 3-7. Install the 100Base-FX Module by inserting it into the guides and sliding it in until it stops

4. Gently push the thumbscrews in and turn clockwise to tighten. Do not over tighten the thumbscrews.

5. Power MIL-S2400 and MIL-S1600 Switches ON, and the Switch will automatically detect the

100Base-FX Module. Plug the fiber cable connector into the 100Base-FX Module. Check the

LEDs to verify that if there is a link and proper connection.

Troubleshooting

This section is intended to help you solve the most common problems on the MIL-S2400 and MIL-

S1600 Switches.

n 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.

n 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-TX network installation.

n

Improper Network Topologies

It is important to make sure that you have a valid network topology. You should make sure that your network topology contains no data path loops. Between any two ends 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 turn on when the power cord is plugged in, you may have a problem with power outlet, or power cord. However, if the Switch powers off after running for a while, 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.

n

Cabling

A. RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair ( STP ) cable for RJ-

45 connections: 100O Category 3, 4 or 5 cable for 10Mbps connections or 100O Category 5 cable for 100Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters ( 328 feet ).

B. 100Base-FX fiber port: Fiber multi-mode connector type must use 50,62.5/125 um multimode fiber cable. You can connect two devices over a 2-kilometer distance. However, Fiber single-mode connector type must use 9/125 um single- mode fiber cable. You can connect two devices over a 60- kilometer distance in full duplex operation.
