1. You can attach your SuperStack II bridge router to a SuperStack II Redundant Power System RPS You will need to order the connecting cable part number 3C8101 from 3Com The following figure shows where to attach this cable Rear panel of unit Gle For full power supply redundancy attach one end of the RPS cable to the rear panel on the bridge router and the other end to the RPS Then attach one end of the power cord to the rear panel on the bridge router and the other end to a power outlet Attach RPS cable here In this configuration the internal supply provides power If the internal supply fails or is switched off or if there is a power failure the RPS is activated and the bridge router reboots To reset a bridge router in this configuration turn the power off wait 5 seconds and turn it back on The bridge router switches to the RPS then switches back to the internal supply to reboot CAUTION For system susceptibility protection always leave the AC cord attached to the bridge router hardware and to a power outlet Internal power supply failure is rare If it occurs the power switch on your bridge router will not operate To reboot you will need to unplug the RPS cable and then plug it back in Replace your bridge router with another bridge router that has a functioning internal power supply as soon as possible Contact your 3Com representative to replace your bridge router Connecting a PC Terminal or Modem
