I've got a DL380G7 and it is being strange. It will POST and I can run the ROMPAQ and load SmartStart 8.7, but all the lights on the status panel are lit up amber.
The UID is blue, the status light is amber, the power button flickers amber, the NICs all show green, but all the other lights on the panel are light up amber.
I've tried different CPUs and RAM with no change.
