These limits are designed to providereasonable protection against harmful interference in a commerical environment. Thisequipment generates, uses and can radiate radio frequency energy and, if not installedand used in accordance with the instructions, may cause harmful interference to radiocommunications. Operation of this equipment in a residential area is likely to causeharmful interference to radio communications, in which case the user will be required tocorrect the interference at their own expense.Information to the UserIf this equipment does cause interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to try to correctthe interference by one or more of the following measures:■ Reorient the receiving antenna.■ Relocate the equipment with respect to the receiver.■ Move the equipment away from the receiver.■ Plug the equipment into a different outlet so that equipment and receiver areon different branch circuits.If necessary the user should consult the dealer or an experienced radio/televisiontechnician for additional suggestions. The user may find the following booklet preparedby the Federal Communications Commission helpful:How to Identify and Resolve Radio-TV Interference ProblemsThis booklet is available from the U.S. Government Printing Office, Washington, DC20402, Stock No. 004-000-00345-4. In order to meet FCC emissions limits, thisequipment must be used only with cables which comply with IEEE 802.3.ICES StatementThis Class A digital apparatus complies with Canadian ICES-003.Cet appareil numérique de la Classe A est conforme à la norme NMB-003 du Canada.CE Statements (Europe)EU Representative:3Com Europe LimitedPeoplebuilding 2, Peoplebuilding EstateMaylands AvenueHemel Hempstead, HertfordshireHP2 4NWUnited KingdomThis product complies with the European Low Voltage Directive 73/23/EEC and EMCDirective 89/336/EEC as amended by European EMC Directive 2004/108/EC.Warning: This is a class A product.

This switch can deliver upto 29.6 W per port (measured at the PD, assuming 100 m Cat 5E cable connectedbetween the PD and the Switch 2426-PWR, subject to power being available), and incertain cable installations this may result in increased cable temperatures. If you are inanyway unsure of how your cable installation is laid out, you should contact an approvedcable installation company for advice prior to using the higher power modes.This guidance is only applicable to pre-standard 802.3at operation. When operating in802.3af (15.4 W) mode it is not necessary to run at lower than rated cable temperatures.
