troubleshooting:dead [IG Manual]

====== Unit does not start ======
Normal power on sequence is described [[product_overview:display|here]].

If your unit does not start correctly when power is turned on there are a couple of steps you can perform in order to try recovering:
  * Make sure the power supply is plugged in. //(Just joking, of course you have plugged it in, but this phrase is so common in all trouble-shooting guides we felt we need to include it too.)//
  * **Check what is the unit's [[product_overview:display|display]] showing:**

===== RST =====
If unit displays just RST for more than a minute then the firmware image in the unit has become damaged and cannot be loaded.
You need to use the [[troubleshooting:lifeboat]] to load a new firmware image into the unit again.

===== CFG RST =====
If unit displays CFG RST for more than a minute then the firmware could not start up correctly. It could fail start because of an incorrect or damaged configuration. Perform a reset to [[settings_and_administration:factory_defaults]]:
  - Hold SEL and ALT buttons pressed when powering on unit.
  - Wait until RST and RS becomes lit.
  - Release SEL and ALT buttons.
  - Power off unit, then power it on again.
If unit still does not start correctly use the [[troubleshooting:lifeboat]] to load a new firmware image into the unit again.

===== Empty (nothing shown) =====
First of all: make sure the display really is completely empty. Units with no WAN access display an //almost// empty display, with just one single dot lit. In that case re-check and adjust your unit's WAN (Internet) connection.

If the display really is completely empty then try using the [[troubleshooting:lifeboat]] to load a new firmware image into the unit. If that fails too the unit, or its power supply, is probably damaged and needs repair.

===== 888 =====
{{:product_overview:display.gif?110 |display segments}}
If display shows "888" (all segments lit) the unit's bootloader has failed to start. The unit is damaged and needs repair.

===== Other =====
If display shows some other data please check the [[product_overview:display|display description page]] for further information.

====== Lifeboat ======
In most cases a seemingly dead unit can be brought back to life by using the [[troubleshooting:lifeboat]].
