Introduction
Radio Characteristics
The ProCurve Radio Port 220 contains two IEEE 802.11-compliant radios: (1)
an 802.11b/g radio operating in the 2.4 to 2.5 GHz band and (2) an 802.11a radio
operating in the 4.9 to 5.875Ghz band. The Radio Port accepts a broad range
of 2.4-2.5GHz and 4.9-5.875GHz external antennas that can be connected to
the Radio Port's two pairs of R-SMA antenna connectors. The following table
lists the 802.11-compliant operating modes for each radio. The three sup-
ported 802.11g operating modes are simultaneous CCK and OFDM, CCK only,
or OFDM only.
Integrated RJ-45 Port
The ProCurve Radio Port 220 has one RJ-45 connector supporting a full-duplex
10/100Base-TX Ethernet port and requires IEEE 802.3af-compliant Power-
over-Ethernet (PoE) from an external source such as a Power-over-Ethernet
(PoE) switch or power injector. Installers can use of a single CAT-5 cable to
supply both Ethernet connectivity and power to the Radio Port, allowing these
Radio Ports to be installed up to 100 m (300 ft.) from a PoE-compliant 10/100
Ethernet port. There is no additional power supply required.
LED Indicators
The Radio Port 220 has LED indicators on the front of the case that visually
display the status of the device. When the Radio Port is mounted above a
suspended ceiling, an additional set of LED indicators on the back of the unit
can be extended through the ceiling tile using a provided lightpipe extender,
making the Radio Port location and status visible from below the ceiling.
