Topic: help: Fireface800 does not initialize

Hello all, long time RME user.
Currently I have a Fireface800 (more than 10 years old IRC) but recently I have many problems to initialize it and communicate with my PC.
The problem is that when I switch the power on, all the lights flash for a second but it does not stablish communication and get recognised with the PC.
To get it recognized I need to power on and off a lot of times (20, 30, 40 times or more) with this problem I dont shut down it normally, but in my area I have power failures in the town and then I have this problem to initialize it again.
Any recomendations to solve that? I need to change the power supply of the unit or what I can do?
Thank you in advance.
