We were thinking of picking up an RPS2300 just to use if we need to walk a power cord from one of our switches for wire management or UPS replacement, and would prefer it not to reload.
However the manual states:
The switch connected to the RPS 2300 might restart when it changes from RPS power to its internal power. We recommend that you first divert switch traffic to an alternate switch to avoid data loss. This does not occur on the Catalyst 3750-E or Catalyst 3560-E switches.
How does this work in real life? Anyone have any experiences hot plugging and hot-unplugging an RPS from a live chassis? Does it work most of the time and just reload the switch once in a blue moon, or is it a common occurence?
When you plugg this in, nothing happens. The switch is still using it internal pwr.
If the switch is using its internal pwr you can safely remove the 2300, nothing will happen.
However if you loose the power to the internal pwr, then the 2300 takes over. When power is back to internal, you have to reload the switch to have it back internal pwr.
The main advantage is, it's up to you when to do it.
If the 2300 is powering the switch and you hot-unplugg it, the switch will do a reload, so this is also best to schedule.
The 2300 is not a "real" redundant-power. It roole is to save you from switch down because of a power-outage, and also if the inernal power get damaged.
