Introducing the HP ProCurve Wireless Access Point 420
Throughout this manual, this access point will be abbreviated as the
Access Point 420.
The Access Point 420 has one 10/100Base-TX RJ-45 port. This port also
supports Power over Ethernet (PoE) based on the IEEE 802.3afstandard. The
access point supports wireless connectivity at speeds up to 54 Mbps based on
the IEEE 802.11g standard.
This access point is designed to be used primarily for connecting wireless
clients to an enterprise network. This access point allows wireless clients to
connect directly to each other, or to connect to other computers or network
resources located on the wired network.
