Re: all the bottom lights flash, then the top light above...

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)

Gs-108a all leds blinking

If devices are plugged into all of the ports and everything works, then there's no problem.
If all the lights are flashing and nothing works, then the switch is dead and you should get it replaced.

All lights flashing

Unless the electronics is broke you seem to be having a wiring related issue. Besides a loop then a short in cable or at a port.

Verify no apparent physical stress displayed on unit or cabling and the correct power supply.

One test for bad electronics is by removing all wires, then look for bent & touching conductors in any of the ports from a poorly crimped cord damaging the port. Try to straighten back into shape - 8 per jack or once the touched eliminated if meta fingers bent my not be able to use that port and check the cable ends for cause and don't use.
Without any cords return power. Only the power light should remain on after about 3 seconds. Any other light display says problem and after verifying correct power supply call it toast - it broken.
If only the power light is lit then connect the 8 conductor (4-pair) Ethernet cable from the cable or DSL modem. That port should light if that device is alive. Note: No telephone RJ-11 size 2 or 3 pair cords, if it fits in a telephone jack you got the wrong one and can damage a port physically. RJ-45s used in Ethernet
are noticeably larger.
Assuming no strangeness in the other lights with the cable/DSL modem connected add one cord at a time to the other ports. Stop and remove any that caused/causes the initially observed condition that is the problem leg; try a different cord and examine the problem cord for physical damage (cuts, tears, squashed blemished area, ends pulled such that conductor open, or two or more wires shorted on an end)
As to internet connection try with only link to Cable/DSL modem and one cable to a PC and then see if the PC is obtaining an IP address via DHCP filling in the interface settings. If Windows "ipconfig" if Mac OS/X or Linux "ifconfig eth0" at the command prompt in a terminal window. Ping the entry for gateway, if no lost packets the connection is sound PC through e-switch to modem. Enter as new problem with modem type and PC operating system if this is a problem after the wiring is straightened out.
When the switch is working correctly Power light is steady ON and Port lights are mostly ON but blink with traffic down that leg.
Does this help?

Need to rest speedstream6520 admin password

Hello mattsss,

1. Turn the modem on. Wait until the modem has stopped booting up and the power light goes solid green.
2. Insert a small tipped object (pen tip or a pin will do) into the hole at the bottom of the modem labelled 'reset'. You may need to hold this in for a couple of seconds before the reset is initiated. You will know when to let go of the reset hole when the power light starts blinking red/green. Remove the small tipped object. All the lights on the front on the modem should flash green and then red then the modem should start to boot as per normal.
3. Once the power light is on solid the modem should be restored to factory defaults.

The default admin username is "admin" and defult password is "admin"

Hub light flashing for long time

If all lights are flashing on this device and there's no computer or devices connected on those ports and only telling us that the hub is already bad and there's no way to reset this hub since it doesn't have any reset button, the next step that you need to here is to ask for a replacement for this device I think it has a 5 year or a life time warranty from Dlink so contact them and have this hub replace...

Hope that helps..........
