    When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring: Cisco SFS 3504 Multifabric Server Switch Hardware Installation Guide OL-14325-01...
  • Page 30: Shock And Vibration

    If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding. Shock and Vibration Cisco SFS 3504 Server Switches have been shock- and vibration-tested for operating ranges, handling, and office vibration and criteria, transportation vibration and criteria, and packaged equipment shock. (See Table A-1 on page A-1.)
