Hi,
Cisco states in FAQ that RPS 2300 can only actively backup 1 Switch with 1 PowerSupply.
Can somebody answer, why is that ?
Is there a limitation in switching the power to more than one outside connectors ?
otherwise this would be a fine backup solution for some more Switches w/o PoE.
regards,
Stefan

RPS2300 can backup 2 Switches if RPS2300 has two power supplies:
Table 1. Number of Switches Actively Backed Up by the Cisco RPS 2300
Cisco RPS 2300 Power Supply Configuration | ||||
1 x 750W | 2 x 750W | 1 x 1150W | 2 x 1150W | |
Cisco Catalyst 3750-E or 3560-E switches with 1150W PS | Not supported | 1 | 1 | 2 |
All other supported network devices | 1 | 2 | 1 | 2 |

sorry,
perhaps I did not define the question clear enough
Is there a limitation in switching the power to more than one outside connectors ?
How is the power switching done internally ?
From logical point of view there is plenty of power available from 1 power supply
for several non-PoE-Switches. Why is that, that only 1 switch can be powered ?

In real world scenarios you wouldn't need to power more than 1 or 2 . These are remote power supplies to power a switch if the internal switch power supply craps out . It is not a UPS (battery backup) if you lose power to a site . They are used so that the switch will continue to run while you get a replacement switch power supply . A good FAQ.

Hi Glen,
well my questions source from real-world scenario and points to the lack of
uninterruptable switchover of c2960 Series switches which our customers want
to avoid.
Thanks for the FAQ. I already mentioned that I read them in my first posting.
Seems to be no standard solution.
regards,
Stefan
