I have a motorola AP-300 which keeps on blinking amber light when i turn it on. how can i reset it or what's wrong with the AP?


From the installation guide for this AP, I find the following:

LED Indicators

The unit has LED activity indicators on the front of the case provide a status display indicating error conditions, transmission, and network activity for the 802.11a (amber) radio or the 802.11b/g (green) radio.


802.11a Activity LED Amber

The amber LED flashes three times per second until firmware is loaded. During boot, 802.11a mobiles cannot associate. After adoption, the amber LED is steady or flashes with 802.11a radio traffic.

The amber LED flashes once per second if an error prevents the 802.11a radio from operating normally.


802.11b/g Activity LED Green

The green LED flashes three times per second until firmware is loaded. During boot, 802.11b/g mobiles cannot associate. After adoption, the green LED is steady or flashes with 802.11b/g radio traffic.

The green LED flashes once per second if an error prevents the 802.11b/g radio from operating normally.


From this, it appears that the 802.11A radio is malfunctioning.


Here is the Motorola support web page for this device.

ProLiant DL160 G6 Server, Part Number 593352-B21, Serial Number USE029N5Z2. The system fails to power on. The power supply has the LED light green. The start button does not turn amber. Do not...


ProLiant ML150 G6 and DL160 G6 (HP Smart Array B110i SATA RAID) does not support more than 4GB memory, (2GBX2 modules) or more added, it works fine with single 2GB module. Boot OS with single module and upgrade system Rompack to the latest version then upgrade B110i controller driver to 6.8.0.32. Shut down the server, add additional modules. It will work fine.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

When I power up the screen flickers for a milisecond and returns to black. The fan runs. The hard drive gives a quick 2 second green followed by two pulses of amber for several minutes and then just quits


It sounds as if you have one of two possible problems, either the light tube in your screen is burnt out or windows is unable to load the video driver. When you see the HD green, it means the drive has started, the amber indicated it is working to load the operating system and then it stops - basically indicating it has found something it cannot load or is missing some files or is possibly busy. If your screen shows either the logo or the boot up screen (black with white letters usually), then the screen is working and it is a windows problem. Occasionally on updates or hardware changes it will take windows 5 minutes, up to a half hour at most to load - if you have a flashing cursor in the upper left corner of the screen, try just waiting to see if it will eventually load.

Can't boot up Dell 5100 Dimension, amber light flashes


When you mean the amber light, is that the blinking hard drive access light or the power light? Different cases have different colors on it. Mine has blue and green lights.

If you see the boot screen (bios) and then after it goes to boot, does it blink and hang?

This could be a simple operating system issue, hard drive or hardware/motherboard issue. If you could provide more information, that would help.
