IBM Netfinity 5500 - Exclamation mark showing in front of the server


I have two IBM NETFINITY 5500 Servers.

Model 8660-62U

One of them currently shows on the front of the casing a big orange exclamation mark.
The server works fine and nothing seems to be problematic right now.

How can I diagnosticate this problem. The server does not tell me anything, the bios says everything is fine.

Last change on this server happened a few weeks back when the network card stopped functionning. I changed the card for a brand new IBM EtherJet PCI Server Card and it worked fine ever since.

The exclamation mark appeared this monday and I rebooted. the mark stayed.

Please advise.

! =System Error Light

Control panel system error LED
The system error LED is turned on on when an error is
detected. If the system error LED is on, remove the cover (open the server )
and check the diagnostic panel LEDs.

I looked at the file and found out that it was PS1 that was defaulting. Looking more deep, I will have to dismantle everything to get to PS1.
