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

For example:

The

the FRU that

caused

the

replacing

a FRU does

not

correct

the

problem,

see

the device

the

FRU

might be defective, or it may have been incorrectly

 

installed.
