Understood. I found a Cisco bug on this issue, that basically says "some switches may reboot upon transfer back to internal power, some may not, do at your own risk". > >> 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." > > I had never problems with this - I always used RPS for redundancy (using > splitted power feeds). Good to hear. I couldn't understand the logic behind the "same AC power source" statement, unless it was just protecting Cisco from having to deal with the issue above (not failing back to the internal P/S once the RPS has taken over), which would be more likely in a scenario where the RPS and internal P/S were on different feeds. --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/
