1. Power _____ Fpx Lancast 8 Port CenturySwitch 11 Troubleshooting Cabling Problems Improper cabling is the primary cause of most network problems particularly for 100Base TX and 100Base FX networks Use only the specified twisted pair or fiber optic cables to avoid most cabling problems e Flat telephone extension cables or Category 3 wires are not the same as Category 5 twisted pair cables and will not function on Fast Ethernet networks There is a wiring problem if the Link Act LED does not illuminate when the RJ 45 plug from a workstation is inserted into the port jack Correct the break in the cable or replace the cable before proceeding If a workstation workstation A does not function while workstations con nected to other ports on the CenturySwitch operate normally remove an RJ 45 plug from a functioning port with a functioning workstation workstation B and insert it into the suspect port If workstation B still works the prob lem may be in workstation A or in the wiring However if workstation B does not work the CenturySwitch may have a defective port Even if you suspect a defective port continue testing Improperly wired workstations may appear functional especially if they are located near the switch Some times a port connected to an improperly wired workstation functions mar ginally while another port does not work at all e Once you have established that the CenturySwitch is2. 1 16 User Guide Product Safety EMC and Compliance Statements This equipment complies with the following requirements e UL e CSA TUV EN60950 safety FCC Part 15 Class A EN55022 Class A emissions EN50082 1 immunity e IEEE 802 3 e IEEE 802 3u IEEE 802 3x IEC 825 1 Classification e Class 1 Laser Product This product shall be handled stored and disposed of in accordance with all gov erning and applicable safety and environmental regulatory agency requirements The following FCC and Industry Canada compliance information is applicable to North American customers only USA FCC Radio Frequency Interference Statement This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of FCC Rules These limits are designed to provide reasonable protection against harmful interference when the equipment is 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 communication 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 Caution Changes or modifications to this equipment not expressly approved by the party responsible for compliance could void the user s authority to operate the equ
