Hi Morningsky,
Nice to see you are returning to your Amiga.
One warning though: you should check the battery in your A2500 asap. It's very likely to leak after years of not using it and will eventually kill the motherboard. It is situated under the drivecage of your A2500, which has to be removed to check the battery. If it has started corroding/leaking, remove it immediately and clean the motherboard if there is corrosion to be seen. You can replace the battery with a new one, although the A2500 doesn't need one to function. Only problem is it doesn't keep the correct date/time anymore.
