    Same problem.....second piece of D-Link hardware that failed in the past two months...first a DIR-655 router. Any solution, other than switching everything back to Linksys???

    The same thing. Top light flash, then bottomline flash, and then - from beginning. Might be a perpetual reset problem, caused by chip failure. It is all, probably, 'cause of unstable power..
    Actually, after a few hours, switch boots himself up, and work properly for another few hours.

Hello all

jpmchugh, I know this response might come to you a bit late, but none the less it might help others who have this issue. I had exactly the same problem until recently, and looks like I found the solution (at least for me). So I thought I'd share it here, since I have not seen a real solution on the various forums I've visited through.

The one common thing I've noted when searching on this and other forums re the 8 bottom blinking lights and then the top right blinking light, repeating over and over again was about a power surge / storm etc.

The exact thing happened to me. A couple of months ago there was a really bad storm, we had a black out in our area and there were some spikes in our electrical systems.

When the black out was over my Gigabit switch was doing the same routine re the lights. The problem for me was the actual power supply unit.

This Switch I've had is about 1.5 yrs old, dunno if I can claim it on warranty from dlink. I've checked the dlink au website and it quotes 5 years, but dunno if it covers storm damage.

Anyways, I took the faulty power supply and the switch to my local jaycar store today. The sales guy noted that the output should be 7.5v, however when he did a test, it was actually showing 12v. He said that the switch must have some sort of built in protection, cause usually supplying 12v to a device that needs 7.5v should have fried the device.

We tried out a replacement power supply and bang.... back in business.

The only kicker was that the replacement power supply cost me around (AUD) $39.95, cause it's one of those fancy multi volt ones. If you can find one that is fixed at 7.5v it might be a cheaper option

Please let me know if this has solved your problem.

Try to connect the switch directly to the power source (do not plug it in the nobreak or stabilizer)

Canon Macro Settings for 100mm lens and Sunpak 12R ring flash


Firstly, be sure to check flash voltage. Your 30D may accept max 6V so that your camera can be shot if the flash unit has higher voltage than 6V.
1. Use low ISO to keep low noise....around f/8 or more depends on your need and how much DOF you want.....Set the shutter speed around 1/125 to your max speed to stop any movement (your subject or camera itself shaking).
2. Above is set in Manual mode (iso100, f/8 1/125 or 1/250), then you just need to leave the flash to work in TTL mode.
3. It needs battery, the connection is for syncing to trigger and release a proper flash power (in TTL mode).
Hope this help!

Hey D1ppy,
There are two ways to get rid of shadows behind a subject, but both require you to use a hotshoe mounted flash. The first way is to bounce the light off a ceiling or some other white surface by turning the flash head towards that surface instead of your subject. The second way would be to connect the flash to the camera using a off camera flash cord and hold the flash above your head when your taking the picture, and by doing this you are able to aim where the shadows show up in the image. Bounced flash is what is called soft light and generally is more pleasing light. I of course am assuming the shadows are caused by the built in flash on the camera. I hope this helps!

Sincerely,
Allan
Go Ahead. Use Us.

Flashing light


Here is what HP has on the subject of the triangle light flashing:
c00028322.gif 1 - Attention Light 2 - Ready Light 3 - Go Light Figure 2: Printer light key c00028323.gif 1 - Symbol for light off 2 - Symbol for light on 3 - Symbol for light blinking
c00028328.gif Door open, media out, no print cartridge, or media jam

The printer is in an error state that requires operator intervention or help. Check the following:
  • The print cartridge door is completely closed.
  • Media is loaded.
  • The print cartridge is correctly installed in the printer.
  • There is no media jam.

Figure 8: Paper jam c00028328.gif 13.JJ.NT JAM IN TRAY 1

13.JJ.NT JAM IN TRAY X

The Attention LED is blinking. Check paper loading then open and close top cover.

When there is a jam in tray 1, verify the paper is loaded correctly, open and close the top cover. Pressing GO is ignored.

When there is a jam in tray X, verify the paper is loaded correctly, open and close the top cover. Pressing GO is ignored. These are the error explanations for just the flashing triangle light, there are many more, but none for just the flashing triangle.

If the light pattern is different let me know (other lights on as well)
-Hope this helps.

My picture is blurry or out of focus.


ake sure your subject is within the camera's range. You should be at least 20 inches away to take a picture without the flash, and 20 inches to 8 feet away to take a picture with the flash. You can take a picture as close as 8 inches in macro mode. When you take macro close-ups, make sure you have adequate lighting (with the flash disabled). Using a tripod will help you capture sharp pictures. Make sure you hold the camera steady after you press the shutter button (until the red light starts to flash), and your subject isn't moving. If you are shaking the camera when you lock the focus, a warning icon appears in the right corner of the LCD. If you want to photograph a moving subject, you can change the shutter speed while the camera is connected to your computer. Try increasing the shutter speed. See Chapter 4 for more information about how to change the shutter speed from the LCD menus. Make sure your flash is not set to flash off. When you focus on a nearby object, your picture's background may appear blurry. Try changing your focus.

Indoor flash images are blurry


It is possible you have the Flash Mode set to one of the Slow Sync modes (lighting bolt with the word Slow). Slow synchronization flash sets a slow shutter speed for the background exposure and fires the flash for the subject exposure. Since the shutter speed is slow, your subject should be still and the camera should be on a tripod otherwise blur can result. Since this mode should only be used when the above conditions can be met, you should use the FILL-IN FLASH (single lighting bolt symbol) mode for most situations that require a flash for correct exposure. Repeatedly pressing the FLASH MODE button will cycle through the various flash mode settings.

Reduce shadow


All solid objects cast a shadow; it cannot be avoided. Certain techniques will help control or reduce the shadow by eliminating or reducing the harshness of the flash. Some of these techniques are: Elevate, eliminate or soften the flash: Make sure the flash is above the lens when you camera is turned to vertical (portrait) orientation. If the on-camera flash is higher than the subject, the lens should not "see" the shadow in most situations. Make sure the camera is higher than the subject, but not so high that you make a shadow in the other direction (under your subject's eyebrows, nose or chin, for example). If there is enough natural light, you might be able to turn the flash off, or you can add "natural" light to the scene by opening curtains, turning on room lights, and so on. In low light you can still photograph without the flash by making sure the camera does not move during the exposure. Consider using a tripod or monopod. The auto color balance feature should automatically adjust the color for the light source. Sometimes it is helpful (at least minimally) to include a white or near neutral grey item within the camera's field of view to assist the camera's color balance assessment. Mixed lighting gives mixed results. Illuminate, eliminate, or move away from the object that has the shadow cast upon it (a wall, for example). Or, use it to your advantage by angling for a better position that may bounce and diffuse the light from the on-camera flash by reflecting light off the wall. Some photographers might lay a white sheet in front of the subject to soften the light by bouncing the light off the ceiling.
