Quick Start

Install the hub

Place the hub on a shelf or table, then plug the power supply into the hub and into a power outlet. Use only the power supply provided with the unit. Leave at least 3 inches (7.62 cm) clearance around the sides of the hub.

Connect devices to the hub

Plug each cable into an RJ-45 port at the rear of the hub.

• Use Category 5 unshielded twisted pair (UTP) cabling to connect 100Base-TX devices to the hub.

• Use Category 3, 4, or 5 UTP cabling to connect 10Base-T devices to the hub.

• Make sure cable length doesn’t exceed 100 meters (328 feet).

Each port automatically detects and matches the speed of the attached device (10Mbps or 100Mbps).

All ports communicate with each other, regardless of speed.

Overview

The Intel Express 130T Standalone Hub is an 8-port hub that operates at 10 or 100Mbps.

• All ports on the hub are capable of 10 or 100Mbps half-duplex

operation.

• Each port on the hub automatically detects the highest possible

speed of an attached device (either 10Mbps or 100Mbps) and matches that speed.

• The Express 130T Standalone Hub’s internal bridge allows all ports

to communicate with each other, regardless of operating speed.

• The Intel Express 130T Standalone Hub monitors port status,

network traffic, and collisions at both 10 and 100Mbps.

This User Guide describes how to install, connect, and troubleshoot the hub.

Connection Guidelines

You can connect the Intel Express 130T Standalone Hub to various PCs, switches, routers, servers, and print servers running at either 10Mbps or 100Mbps. Each port on the Express 130T Standalone Hub automatically matches the highest possible speed of an attached device.

Note For guidelines on connecting to another hub, see “Connecting

to Hubs and Switches” on page 6.

Connecting to 100Base-TX devices

• Use Category 5 unshielded twisted pair (CAT 5 UTP) cable.

• Always limit the cable length between the hub and any connected PC, server, switch, or print server to 100 meters (328 feet). The IEEE specification requires this distance.

• See “Connecting to a 100Mbps hub” on page 6 for information on connecting to 100Mbps hubs.

• Use ports 1-8.

Connecting to 10Base-T devices

• Use Category 3, 4, or 5 unshielded twisted pair (CAT 3, 4, or 5 UTP) cable.

• Always limit the cable length between the hub and any connected device to 100 meters (328 feet). The IEEE specification requires this distance.

• See “Connecting to an existing 10Mbps network” on page 7 for information on connecting the Express 130T Standalone Hub to a 10Mbps network segment.

• Use ports 1-8.

Orange Port has been autodisabled (partitioned). Blink Activity detected on port. Off No link. Speed LEDs show the operating speed of a particular

port—10Mbps or 100Mbps.

Autodisabled Ports

The Express 130T Standalone Hub automatically disables a port when it detects a serious error on that port, such as a series of more than 64 collisions on a single packet. Once the hub sees a valid packet from the device or is able to transmit a packet from the port, it automatically reenables the port. Connected devices aren’t usually affected by an autodisabled port because the port is reenabled so quickly.

If a port remains autodisabled, check the connected device’s network adapter and cabling, or unplug the network cable for a few seconds, then reattach it.

Connecting to Hubs and

Between hubs: Category 5 UTP 5 meters maximum

Switches

Connecting to another 130T hub

Using no more than 5 meters of CAT 5 UTP cable, connect the Daisychain port on one hub to any port except the Daisy-chain port on the other hub. Do not connect two Daisy-chain ports. If you do, the two connected hubs won’t be able to communicate.

Note Remember, if you use the Daisy-chain port, you can’t

simultaneously use Port 1 on the same hub.

You can connect the Express 130T Standalone Hub to a 100Mbps hub that supports daisy-chaining.

You can connect no more than two Express 130T Standalone Hubs. Always limit the cable length between the hub and any connected PC,

server, switch, or print server to 100 meters (328 feet). The IEEE specification requires this distance.

Connecting to a 100Mbps hub

If you want to connect the Express 130T Hub to a 100Base-TX hub that supports daisy-chaining, such as the Intel Express Standalone Hub, follow the procedure for connecting two 130T hubs.

Do not connect the Express 130T Standalone Hub to a 100Base-T Class I hub, such as the Express 10/100 Stackable Hub.

Connecting to an existing 10Mbps segment

Using no more than 100 meters of CAT 3, 4, or 5 UTP cable, connect the Daisy-chain port on the Express 130T Standalone Hub to an MDI-X port on the 10Mbps hub or switch.

The Express 130T Standalone Hub’s internal bridge allows devices connected to the hub to communicate with devices on the 10Mbps segment.

Connecting to a switch

Connecting hubs to a switch, such as the Intel Express 510T Switch, allows you to extend your network topology. The cable length between the Express 130T Standalone Hub and the switch must not exceed 100 meters.

If you’re connecting to a 10Mbps switch, make sure you use no more than 100 meters of CAT 3, 4, or 5 UTP. If you’re connecting to a 100Mbps switch, make sure you use no more than 100 meters of CAT 5 UTP.

Troubleshooting

Symptoms and solutions

Most problems with the Express 130T Standalone Hub are caused by incorrect cabling. If you have problems connecting devices, check your cabling first.

A port LED is orange.

This means the hub has autodisabled (partitioned) a port.

• Check the attached device’s LAN adapter and cabling.

• See “Autodisabled Ports” on page 5.

A port LED doesn’t light after a cable is attached.

This means the connected device has a defective network adapter, cable, or port.

• Test the cable (see “Testing a cable” on page 11).

• Make sure the correct cable type (straight-through or crossover) is being used. See “Straight-through vs. crossover cables” on page 10.

• Check the LAN adapter.

• Try another port on the hub.

A 10/100 LAN adapter connects at 10Mbps but not at 100Mbps.

• Check to see if the LAN adapter’s speed is forced to 10Mbps.

• Make sure you’re using CAT 5 cable to connect the LAN adapter to the hub.

After you’ve forced a network adapter to 100Mbps from 10Mbps, you’re unable to connect to the network.

• Unplug the network cable for a few seconds, then reconnect.

Tips

• Make sure cable length between the hub and attached PCs, servers, switches, and print servers, doesn’t exceed 100 meters. The IEEE specification requires this distance.

• If you’re connecting two Express 130T Standalone Hubs or a 130T Standalone hub and a 100Base-TX hub that supports daisychaining, make sure the cable length between hubs doesn’t exceed 5 meters.

Cabling Requirements

Straight-through vs. crossover cables

Ports 1-8 on the Express 130T Standalone Hub are wired MDI-X (indicated by the ‘x’ next to the port number), which allows you to use a straight-through cable when connecting to a PC or server (network adapter cards are wired MDI). For direct connection to another MDI-X port (such as a switch port), use a crossover cable.

Determining which cable to use

The following guidelines are based on the Express 130T Standalone Hub, the Intel Express 510T Switch, Intel EtherExpress™ LAN Adapters, (server or PC), and Intel NetportExpress™ print servers.

For this connection Use this cable

Hub to switch Crossover Hub to server or PC Straight-through Hub to print server Straight-through

Instead of using a crossover cable from ports 1-8, you can use a straight-through cable from the Daisy-chain port. Remember, you can’t use Port 1 if you’re using the Daisy-chain port.

Testing a cable

Here’s an easy way to test the link integrity of a cable:

1 Plug one end of the cable into the Daisy-chain port. 2 Plug the other end of the cable into port 2X. 3 Check port 1 and port 2 Speed LEDs on the front of the unit.

If these ports are lit, you have a functioning straight-through cable. If the ports are unlit, remove the cable from the Daisy-chain port and

reinsert it in port 1X. If the Speed LEDs for ports 1 and 2 are on, you have a functioning crossover cable.

If the LEDs are unlit, you have a bad cable. If a cable passes either of these tests, but the network connection is

slow, verify that wires 1 & 2 and 3 & 6 on the cable are twisted pairs.
