operating systems: Windows 98, Windows ME, Windows NT 4.0 Service Pack 6, Windows 2000, or Windows XP. It is recommended that this computer become the dedicated workstation for managing and configuring the access point and the wireless network.

POWER REQUIREMENTS

The access point complies with the IEEE 802.3af Power-over-Ethernet standard. It receives power over standard category 5 straight (8-wire) Ethernet cable. Installation requires the use of either the 3Com AC adapter or IEEE 802.3af compliant power supply equipment (output power rated 48 V dc @ 350 mA maximum). Such equipment must be safety certified according to UL, CSA, IEC or other applicable national or international safety requirements for the country of use. All references to the AC adapter in this document refer to equipment that meets these requirements.

Because the AC adapter plug is the only means of disconnecting the access point from power, make sure the power outlet is accessible.

See “Using the Included AC Adapter” on page 15 and “Using a Power-Over-Ethernet LAN Port” on page 17.

Note: For use of the 3Com AC adapter (part number 61-0107-000) in Norway: This

product is also designed for use on an IT power system with phase-to-phase voltage of 230 V.

SAFETY INFORMATION

!

!

!

This equipment must be installed in compliance with local and national building codes, regulatory restrictions, and FCC rules. For the safety of people and equipment, only professional network personnel should install the access point, cables, and antennas.

CAUTION: If you supply your own Ethernet cable for connecting power, be sure that it is category 5 straight-through (8-wire) cable that has not been altered in any way. Use of nonstandard cable could damage the access point.

CAUTION: To comply with FCC radio frequency (RF) exposure limits, a minimum body-to-antenna distance of 1 meter (3 feet) must be maintained when the access point is operational.

CAUTION: To avoid possible injury or damage to equipment, you must use either the provided power supply or IEEE 802.3af compliant power supply equipment that is safety certified according to UL, CSA, IEC, or other applicable national or international safety requirements for the country of use. All references to power supply in this document refer to equipment meeting these requirements.
