CHAPTER 10: COMPLIANCES AND STANDARDS
10.1 COMPLIANCES
All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to
PCs or servers, or to other switches or hubs.
10.1.1 FCC RFI STATEMENT
This equipment has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of part 15 of FCC
Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to
operate the equipment.
You may use unshielded twisted-pair (UTP) for RJ-45 connections – Category 3 or better for 10 Mbps connections, Category 5 or better for
100 Mbps connections, Category 5, 5e, or 6 for 1000 Mbps connections. For fiber optic connections, you may use 50/125 or 62.5/125 micron
multimode fiber or 9/125 micron single-mode fiber.
10.1.2 CE MARK DECLARATION OF CONFORMANCE FOR EMI AND SAFETY (EEC)
This equipment has been tested and found to comply with the protection requirements of European Emission Standard
EN55022/EN61000-3 and the Generic European Immunity Standard EN55024.
