Installation Procedures
Installing the
Access Point 420
Direct Console Access
To connect a console to the
access point, follow these steps:
1. Connect the PC or terminal
to the access point’s Console
port using a DB-9 female-to-
female serial cable. (If your
PC or terminal has a 25-pin
serial connector, first attach
a 9-pin to 25-pin straight-
through adapter at one end
of the console cable.)
The Console cable is
described below. A null-
modem cable or an HP
serial cable, part number
5184-1894 (shipped with
many HP ProCurve
switches), may be used.

Connection to PC serial ports also requires a crossover (null-modem)
cable with a female DB-9 connector on both ends. Terminal connections
will vary, requiring either a DB-9 or DB-25 connector, male or female.
Serial cable options between an HP ProCure Wireless Access Point 420
and a PC terminal are shown in the following table.
