Observe front panel LCD blink continuous Dell Power Edge R610 1U server. When press next to button "i" its convert steady amber not steady blue. Kindly suggest.


Blinking blue means that the server identify button is toggled on, if it turns to amber it means that the server may have a failure in the logs, if the server boots normally you can get the a DSET (it contains hardware log), if it doesn't boot you can get it from the iDRAC (if available). You can download DSET here:

If need any help running DSET let me know.

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

Blinking amber (orange) indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this could indicate a problem with the power connections for the CPU on the system board (see "Power Problems" in your Owner's Manual).
