Amber light blinking next to ethernet cable

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.A power supply or system board failure has occurred. Try to isolate the problem by removing or disconnecting all cards, i.e. video, sound cards and disconnecting CD/DVD and hard drives.

An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

If Try one or more of the following

Ready light does not turn on and the camera does not work.

• Turn on the camera (Turning on the camera).

• Install new batteries (Loading the battery) or charge rechargeable batteries.

• Turn camera off, then back on.

Ready light blinks green.

• Camera is operating normally.

Ready light blinks amber.

• Wait. Resume picture taking when the light stops blinking and turns green.

Ready light blinks red and camera turns off.

• Install new batteries (Loading the battery) or charge rechargeable batteries.

Ready light glows steady red.

• Transfer pictures to the computer (Transferring pictures with the USB cable), delete pictures from the camera (Deleting pictures/videos), switch image storage locations (), or insert a card with available memory (Using an optional SD/SDHC or MMC card).

• Wait. Resume picture taking when the light turns green.

• Change the image storage location to internal memory (), or use a different card.

Ready light is off or glows steady green.

• Camera is operating normally

Turn off the RAM disk on the printer.

Follow these steps:

Troubleshooting steps

1.
Verify that the formatter light is blinking or steady. If the formatter is blinking, it is functioning properly and probably does not need to be replaced. If the formatter light is not blinking, proceed to Step 2.
2.
Turn off the printer and unplug the power cord.
3.
Remove the HP Jetdirect card, third-party device, hard disk, parallel cable, or IFR cable from the formatter if one is installed.
4.
If the error continues with accessories removed from the formatter, perform a cold reset on the printer. Ensure the HP Jetdirect card is not in the printer during a cold reset or the card settings will be changed back to default settings. To perform a cold reset, do the following:
1.
Turn on the printer.
2.
Watch the control panel.
3.
When the memory starts counting, press and hold the green (Select ) button.
4.
Continue holding the green check button until the Ready, Data, and Attention lights flash once, and then stay on steady.
5.
Release the check button when the Ready, Data, and Attention light are on steady.
The control panel will display SELECT LANGUAGE .
6.
Press (Down Arrow ) button once. The control panel will display COLD RESET
7.
Press (Select ). The printer will perform a cold reset and then continue its power-on sequence.
5.
If the printer comes up to ready, print a Configuration page. If a 49 error occurs from printing internal pages, continue on to the next step.
6.
Turn the printer off and unplug the power cord.
7.
Remove the eight screws around the formatter.
8.
Remove the formatter. See Figure 1.
9.
Reseat the firmware and memory modules on the formatter. Check for any DIMMs that are non-HP and remove them. Non-HP DIMMs are not supported by HP and may cause this error. Replace with HP DIMMs, if necessary.
10.
Reseat the daughter (interconnect) board. The daughter board is connected to the formatter behind EIO slot #1. To release the daughter board, push in the black retaining tab underneath the formatter then lift up the one side of the daughter board.
11.
Reseat the daughter board.

12.
Install the formatter.
13.
Turn the printer on again.
14.
If it comes up to READY , print a configuration page. If a 49 error does not appear from printing internal pages, or at power up, continue to the next step.

15
Install the HP Jetdirect card and hard disk before installing the formatter. Verify that each device is properly seated.
16
Test any EIO devices, by turning off the printer, installing each device separately, and printing a Configuration page. Repeat for each EIO device.
17
If the 49 error occurs with any EIO device installed, replace that EIO device.

If your JetDirect Ethernet card does not show up on the configuration page then the JetDirest is bad. This is somewhat common with the 610N cards. You will need a new card. They are cheap to buy just about anywhere including Ebay. I have replaced dozens of them over the years.

If the power light is amber and green or steady amber — A device might be malfunctioning or incorrectly installed.

• Remove and then reinstall the memory modules.
• Remove and then reinstall any cards.
• Remove and then reinstall the graphics card, if applicable.

If the power light is blinking amber —
The computer is receiving electrical power, but an internal power problem might exist.

• Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
• Ensure that the processor power cable is securely connected to the system board.

Could it be that green is high speed and amber is low speed? Or vice-versa?

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Try, unplugging the power cable from the pc, and reinsert it, if this does not help try a differnt power outlet, if this dont help, open the computer, take the power Molex conector out of the mother board and try turning it on, if this dont help, take out the Memory modules and reseat them, if this dont work you may want to ring up dell support.

Hope this helps!

make sure that all the cables are connected FULLY.
blinking light means that there is no signal.

It has been a few months, so you probably have resolved this -- but just in case someone else is looking to find out the IP address on the internal print server of an HP Laserjet 4000n printer so they can set it up on their network, here are the steps to find the IP address on the HP JetDirect internal print server:

1. Have the Ethernet cable plugged in to the router and the JetDirect 600n card and power it on.
2. Make sure display screen on printer says "Ready".
3. Press the Menu button on the printer until you see Information Menu.
4, Press the Item button on the right (+) side until you see Print Configuration page.
5. Press the Select button and a configuration page should print.

One page is the printer's configuration and the other page is the print server configuration page. If you have a good JetDirect card, and good connection to your router, the IP address of the printer, plus its subnet mask and default gateway should be shown on the EIO configuration page.

If the printer has been manually set with a static IP address, subnet mask and default gateway that will not work on your network, you will see the settings will indicate "Configured by" User Specified.

To clear those settings and allow DHCP setting, perform a cold reset on the JetDirect card, by powering off the printer, holding down the green "Go" button and powering it back on until you see "COLD RESET," let go of the green Go button, wait a couple of minutes, then run another configuration page to see the freshly assigned DHCP address of the print server.

Hope this helps someone.
