We are looking at options to provide redundancy for the internal A/C power supply in some 3550-48-EMIs. It seems that the following RPS models will work:
RPS-300 RPS-675 RPS-2300 We plan to do a 1-1 config (1 RPS for 1 switch), so we are leaning towards the RPS-300 for cost reasons. I've reviewed various threads in the archive, and see where others have had problems with the RPS-300's allowing fall-back to the internal A/C power supply after it has taken over on the DC source. Was this an IOS issue, a hardware issue with the switch and/or RPS, or ? Also, I keep seeing this warning in the docs: "The Catalyst 3550 switch and the Cisco RPS 300 or RPS 675 should be connected to the same AC power source." We had planned to power the internal source from one PDU, and the RPS from another PDU (both PDUs are fed by the same UPS source, but we wanted to guard against a PDU failure). What is the real issue here -- and am I asking for trouble by ignoring this warning? TIA. --Mike _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
