When using an RB750UP or OmniTik UPA with the stock 2.5A power supply, we often see a voltage drop to as low as 20V on some of our installations with longer Cat5 runs, and it appears to be affecting the stability of some of our point-to-point links.
Are there any caveats to using a 24V/3A (or 4A or 5A) power supply in these situations? Is there much risk to overheating the Cat5 (24 AWG solid-conductor, foil-shieded CMX) at those power levels?
