Fan Faults and Warnings
This section provides the fault (
FLT
) and warning (
WRN
) messages you will see in the LCD if
there is a problem with a fan in the B2000 workstation.
A chassis code which indicates that a fan has failed (
FLT D01
n
) or is running too slowly
(
WRN D02
n
) within a B2000 workstation specifies the fan number,
n
. Table 3-1 lists the fan
numbers and their names. To locate the correct fan, see Figure 3-5 on the next page.
Here is an example of a fault message for the system fan (4):
Here is an example of a warning message for the processor fan (5):
