SPECIFICATIONS

3COM
®
MINIMUM SYSTEM
REQUIREMENTS
Computer with an Ethernet 10BASE-T,
10/100, or 10/100/1000 interface
configured for Internet communication
Operating system that supports an
Ethernet connection with an IP stack
(Installation CD Discovery Application
requires Windows XP, or Windows
2000)
PCs and laptops require 802.11a or
802.11b/g adapter cards for wireless
access
MEDIA INTERFACES
RJ-45, IEEE 802.11a, 802.11b, 802.11g
One 10BASE-T/100BASE-TX IEEE
802.3af-compatible PoE port with
auto-negotiation
DATA RATES
802.11g/a
: 54, 48, 36, 24, 18, 12, 9,
6 Mbps with automatic fallback
802.11b
: 11, 5.5, 2, 1 Mbps with
automatic fallback

OPERATING CHANNELS:
Channel availability depends on local
country regulations. Wireless LAN
system administrator must choose
correct country of operation. Channels
are then automatically configured
to comply with specified country's
regulations.
