User manual NETGEAR GS504T Installation Guide

[. . . ] If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Connect the equipment into an outlet on a circuit different from that which the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help. EN 55 022 Declaration of Conformance This is to certify that the NETGEAR Model GS504T Copper Gigabit Switch is shielded against the generation of radio interference in accordance with the application of Council Directive 89/336/EEC, Article 4a. Conformity is declared by the application of EN 55 022 Class A (CISPR 22). [. . . ] Solution Check the power cord connections for the switch and the connected device. Make sure all cables used are correct and comply with Ethernet specifications. Check the crimp on the connectors and make sure that the plug is properly inserted and locked into the port at both the switch and the connecting device. Make sure all cables used are correct and comply with Ethernet specifications. Check for a defective adapter card, cable, or port by testing them in an alternate environment where all products are functioning. Half- or full-duplex setting on the switch and the connected device are not the same. One or more devices are not properly connected, or cabling does not meet Ethernet guidelines. Make sure the remote link partner is set to auto negotiate. Verify that the cabling is correct. Be sure all cable connectors are securely positioned in the required ports. Equipment may have been accidentally disconnected. FDX/COL LED is blinking yellow excessively. Some collisions are normal when the connection is operating in half-duplex mode. Recheck the link partner settings. troubleshooting 5-1 GS504T. Manual.

FINAL 6/2/00 12:49 PM Page 23 APPENDIX B: CONNECTOR PIN ASSIGNMENTS This appendix provides information about the RJ-45 plug and the RJ-45 connector used for the NETGEAR Model GS504T Copper Gigabit Switch. RJ-45 Plug and Vista RJ-45 Connector In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use RJ-45 plugs. The RJ-45 plug accepts 4-pair UTP or shielded twisted pair (STP) 100 ohm cable and connects into the vista RJ-45 connector. The vista RJ-45 connector is used to connect stations, hubs, and switches through UTP cable; it supports 10 Mbps, 100 Mbps, or 1000 Mbps data transmission. The RJ-45 plug and vista RJ-45 connector are both illustrated in Figure B-1. 12345678 8 1 711EA Key: 1 to 8 = pin numbers Figure B-1.

Manual. FINAL 6/2/00 12:49 PM Page 25 APPENDIX C: CABLING GUIDELINES This appendix provides specifications for cables used with the NETGEAR Model GS504T Copper Gigabit Switch. Fast Ethernet Cable Guidelines Fast Ethernet uses UTP cable, as specified in the IEEE 802. 3u standard for 100BASE-TX. The specification requires Category 5 UTP cable consisting of either two-pair or four-pair twisted insulated copper conductors bound in a single plastic sheath. 100BASE-TX operation uses one pair of wires for transmission and the other pair for receiving and for collision detection. When installing Category 5 UTP cabling, use the following guidelines to ensure that your cables perform to the following specifications: · Certification Make sure that your Category 5 UTP cable has completed the Underwriters Laboratories (UL) or Electronic Testing Laboratories (ETL) certification process. · Termination method To minimize cross-talk noise, maintain the twist ratio of the cable up to the point of termination; untwist at any RJ-45 plug or patch panel should not exceed 0. 5 inch (1. 5 cm). cabling guidelines C-1 GS504T. Manual. FINAL 6/2/00 12:49 PM Page 26 Category 5 Cable Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a maximum of 328 feet (ft) or 100 meters (m) in length, divided as follows: · 20 ft (6 m) between the hub or switch and the patch panel (if used) · 295 ft (90 m) from the wiring closet to the wall outlet · 10 ft (3 m) from the wall outlet to the desktop device The patch panel and other connecting hardware must meet the requirements for 100 Mbps operation (Category 5). [. . . ] · cabling or bundling of multiple Category 5 cable. This is regulated by ANSI/EIA/TIA-568A-3, and can adversely affect all parameters of the cabling if not correctly implemented. Near End Cross Talk (NEXT) This is a measure of the signal coupling from one wire to another, within a cable assembly, or among cables within a bundle. NEXT measures the amount of cross-talk disturbance energy that is detected at the near end of the link--the end at which the transmitter is located. NEXT measures the amount of energy that is "returned" to the sender end. The factors that affect NEXT and cross talk are exactly the same as outlined in the Return Loss section. The cross-talk performance is directly related to the quality of the cable installation. cabling guidelines C-6 GS504T. Manual.
