To figure out which wire is wire number 1, hold the
cable so that the end of the plastic RJ-45 tip (the part
that goes into a wall jack first) is facing away from you.
Flip the clip so that the cop-
per side faces up (the springy
clip will now be parallel to
the floor). When looking
down on the coppers, wire 1
will be on the far left.

· Computers should never be connected directly together
on a network. They should always be connected to a hub.
· Only two 100Mbps Fast Ethernet hubs can be cascaded,
(or uplinked), together. To cascade more than 2 100Mbps
hubs, a switch or a repeater must be used.
· The maximum cable length from a node to a repeater,
switch, or hub is 100 meters (328 feet).
· The maximum length for a Category 5 cable between a
100BaseTX or 10BaseT workstation and a stackable or
other shared bandwidth hub is 100 meters (328 feet).
· The maximum distance between 2 100BaseTX hubs
without a switch is 5 meters (16.4 feet).
· The maximum distance between 2 10BaseT hubs, (or a
10BaseT hub and an Auto-Sensing hub), is 100 meters
(328 feet).
