Media Requirements

Incorrect cabling is often the cause of network performance problems.
Read the next two pages to make sure your cabling is correct.
10Base-T
The 10Base-T Ethernet specification allows you to use CAT 3, CAT 4,
or CAT 5 UTP cabling. The limit is 100 meters between any two devices.
100Base-TX
The 100Base-TX Fast Ethernet specification requires that you use CAT
5 UTP cabling to operate at 100Mbps. If you use lower grade cabling
(CAT 3 or CAT 4) you may get a connection, but also experience data
loss or slow performance. You're limited to 100 meters between any two
devices.
1000Base-T
The 1000Base-T Gigabit specification requires that you use CAT 5 UTP
cabling to operate at 1000Mbps. If you use a lower grade cabling you will
experience either no connection or extreme data loss. The maximum
distance between any two devices is 100 meters.
1000Base-SX/1000Base-LX
The optional 1000Base-SX and -LX Gigabit Modules provide a high-
speed connection to another device up to 5 km away. The maximum
distance depends on the type of cable used. Refer to the following table
for a list of cable types and maximum distances. Use cables with an SC-
type fiber optic connector.
