Trouble-shooting system boot problems

Use the steps in the following table to perform basic trouble-shooting on your R200 system if it does not boot.

Step	Action
1	Look for a description of the problem on the LCD and console. Follow the instructions, if provided, on the LCD and console.
2	Check all cables and connections, making sure that they are secure.
3	Ensure that power is supplied and is reaching the storage engine. Check the LEDs above the power cords. They should be green.
4	Check the power supplies on the storage engine and disk shelves. If the LEDs on a power supply are not illuminated, remove the power supply and reinstall it, making sure that it connects with the backplane.
5	Power off the storage engine and disk shelves, then power on the disk shelves. See Storage engine LED responses at startup and Disk shelf LED responses at startup for a description of the LED responses.
6	Use the onboard diagnostics to check the disks. See the Diagnostics Guide for more detailed information.
7	If the storage engine does not boot successfully, it might have a missing or corrupted boot image on the CompactFlash card, or might have a failed CompactFlash card or interface. Call Network Appliance Customer Support at + 1 (888) 4-NETAPP.
