Cabling Requirements

Incorrect cabling is often the cause of network configuration problems. It’s important that you understand cabling requirements before connecting devices to the switch.

UTP requirements

The 100BASE-TX Fast Ethernet specification requires you use Category 5 unshielded twisted-pair (CAT 5 UTP) cabling to operate at 100 Mbps per second. If you use lower grade cabling (CAT 3 or CAT 4), you may get a connection, but will soon experience data loss or slow performance.

The 10BASE-T Ethernet specification allows you to use CAT 3, CAT 4, or CAT 5 UTP cabling.

You’re limited to 100 meters between any two devices with UTP cable whether you’re running at 10 Mbps or 100 Mbps. However, you can extend the total diameter by installing a fiber optic media adapter and using fiber optic connections between switches, or between the switch and a hub (repeater), router or bridge. See page 12 for an example.

Fiber optic requirements

The optional 100BASE-FX fiber optic media adapter (Intel product code ES101MAFX) lets you use multimode fiber optic cable to connect two switches, or to connect the switch to a hub, bridge, or router. The media adapter uses an SC fiber optic connector.

With multimode fiber optic cable, signals can travel up to 412 meters between two switches or between the switch and a router when the link is configured at half duplex. If configured at full duplex, the signal can travel up to 2 kilometers.

The signal can travel up to 160 meters between the switch and a hub (repeater). Full duplex isn’t possible between the switch and a hub.
