IBM 380Z manual Diagnostic Error Codes, Device ID, For example, Icon Device

If a device that is not installed appears in dark shade (for example, FDD-2 appears in dark shadeno secondwhen

FDD is installed), do the following:

1.	Replace	firstthe device in the configuration, such	as
	an FDD-1.
2.	If the	problem persists, replace the system	board.

The Parallel, and Serial icons are always displayed in dark shade, because the icons represent subsystems of the system board, not the attachment of devices.

The FDD-1 icon representsfirst thedrive in the system configuration for each type of device. The FDD-2 icon

represents secondthe drive, attached through a port replicator.

Diagnostic Error Codes

If an error is detected, the following appears:

LargeX on the left side of the device icon.

Device ID (three digits)

Error code (two digits)

FRU code (four digits)

For example:

The	device	ID	and error		code indicate		the	detailed		portion
of	the FRU that			caused	the	error. If	replacing		a FRU does
not	correct	the	problem,		see	the device	ID	or	error	code
from the previous failure. If they changed,								the	new	FRU
might be defective, or it may have been incorrectly
installed.
Device ID:		If	an	error	is detected by		the	diagnostic

tests, a three-digit device ID is displayed, indicating the suspected device.
