IBM PS/2 - Cables/switching devices
Applicable to: World-Wide
Service Information:
Cable Types and Lengths:-
Only IBM manufactured cables in the length supplied by IBM are tested and supported on PS/2 systems. The performance of non-IBM and locally fabricated cables and switching devices are the customer's/supplier's responsibility. The use of non-IBM manufactured cables and/or switching devices attached to display, serial, parallel, keyboard and moose ports, may cause unpredictable and difficult to diagnose problems. This can be caused by factors associated with data signals (such as cable impedance and reactance*) which cannot be measured without special test equipment.
A simple DC (Direct Current) resistance check, normally done by a Volt-OHM Meter, is insufficient to determine that a cable or device will function correctly during system operation. Extended length and/or improperly shielded cables or switching devices may also radiate signals beyond acceptable FCC (Federal Communication Commission) Class B Standards. This may cause interference problems with other non-associated electrical equipment.
* Excessive reactance and impedance causes degradation of signal quality.
