Installation Procedures
Installing the
Access Point 420
5. Connect the Network Cable
Connect the network cable, described under “Cabling Infrastructure”
(page 2-4), from the network device or your patch panel to the RJ-45 port on
the access point.
Using the RJ-45 Connectors
To c onn ec t:
Push the RJ-45 plug into the RJ-45
port until the tab on the plug clicks
into place. When power is on for the
access point and for the connected
device, the 10/100Base-TX link LED
should light to confirm a powered-on
device (for example, a switch) is at
the other end of the cable.
If the 10/100Base-TX link LED does
not go on when the network cable is
connected to the port, see “Diag-
nosing with the LEDs” in chapter 5,
“Troubleshooting”.
To disconnect:
Press the small tab on the plug and pull the plug out of the port.
6. Position the Antennas on the Access Point
The antennas emit and receive signals along a toroidal plane—and thus
provide more effective coverage when positioned along different axes. For
example, you might position the antennas around 45 to 90 degrees from each
other.
The access point compares the strength of an incoming signal on both
antennas, and uses the antenna receiving the stronger signal to communicate
with a wireless client. Note that both antennas are used to transmit, but never
at the same time.
The access point’s antennas can also be replaced by various external antenna
options that offer extended radio range and specific radio coverge patterns.
For further information, see chapter 4, “Using an External Antenna with the
Access Point 420”.
