10/100Base-TX • 10 Mbps operation:
Category 3, 4, or 5, 100-ohm unshielded
twisted-pair (UTP)
• 100 Mbps operation:
Category 5, 100-ohm UTP or shielded
twisted-pair (STP) cable.

Cabling Infrastructure - Ensure that the cabling infrastructure meets
the necessary network specifications. See the following table for cable
types and lengths, and see appendix B, "Access Point Port and Network
Cables" for more information:
Summary of Cable Types to Use With the Access Point
Twisted-Pair Cables
Installation Location - Before installing the access point, plan its loca-
tion and orientation relative to other devices and equipment:
• Try to place the access point in the center of your wireless network.
Normally, the higher you place the antenna, the better the perfor-
mance. You may need to reposition the access point after testing the
signal strength on several wireless clients to ensure that the access
point's location provides optimal reception throughout your office.
• In the back of the access point, leave at least 7.6 cm (3 inches) of space
for the twisted-pair cabling and the power cord.
• On the sides of the access point, leave at least 7.6 cm (3 inches) for
cooling.
Length Limits
100 meters
Note: Since the 10Base-T operation is through
10/100Base-TX ports, if you ever want to
upgrade the ports to 100Base-TX, it would be
best to cable the ports initially with category 5
cable.
The 10/100-Base-TX port on the
Access Point 420ww/na uses an MDI pin
configuration, which requires you to use
straight-through cable when connecting to
another device that has an MDI-X port, or
crossover cable when connecting to a device
that has an MDI port. However, if the device to
which you are connecting supports auto-
MDIX, then you can use either straight-
through or crossover cable.
