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.
Check for links
Each port at the rear of the hub has a
corresponding LED on the front of the
hub. Make sure the LED of each port
you’re using shows a green link light at
either 10 or 100Mbps.

Frequently asked questions
Does each port operate at 10Mbps or 100Mbps?
Yes. Each port on the Express 130T Standalone Hub is capable of
10Mbps or 100Mbps half-duplex operation.
Do I have to set a port’s speed?
No. Ports on the Express 130T Standalone Hub automatically detect
and match the speed of an attached device.
Do ports operating at different speeds communicate with each
other?
Yes. The Express 130T Standalone Hub’s internal bridge allows all
ports to communicate with each other, regardless of operating speed.
Can I connect the Express 130T Standalone hub to another hub?
Yes. For connection guidelines, see “Connecting to Hubs and
Switches” on page 6.
Can I configure the Express 130T Standalone Hub for full-duplex
operation?
No. Hubs do not support full-duplex operation.
Can I wall mount the Express 130T Standalone Hub?
Yes. Using the two wall mount hole guides on this page, mark and drill
into the wall where you want to mount the hub. Then insert the
provided screws into the wall and hang the hub.

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.

LED Indicators
The LEDs on the front of the hub indicate the status of each port as
well as the overall condition of the hub.
LED Color Meaning
Power Green Hub is receiving power.
Traffic % Green Utilization is low to medium (3-12 percent).
Orange Utilization is medium to high (25-50+ percent).
Collisions Green Collisions detected.
Off No collisions detected.
Collisions are normal in an Ethernet environment.
Continuous blinking indicates an overloaded network.
Speed Green Port has a link.
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.

You can connect the Express
130T Standalone Hub to a
100Mbps hub that supports
daisy-chaining.
Connecting to Hubs and
Switches
Connecting to another 130T hub
Using no more than 5 meters of CAT 5 UTP cable, connect the Daisy-
chain 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.
Between hubs:
Category 5 UTP
5 meters maximum
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.

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.
