See Note 1 
Indicates a soft failure condition. 
 
Note 1:  If a soft failure is detected, the soft failure indication alternates with the 
redundancy status indication. 
 
Controller display in BOOT mode 
The C300 Controller faceplate display rotates through the following fields when 
controller is executing boot firmware: 
<Device Index> -> <Controller State>-> <Redundancy Role> 
For example:  #003 -> ALIV -> PRI 
Table 11  Display indications when controller is in boot mode 
 
FTE Device Index, where nnn can be 001 to 
255.  Does not change with redundancy role. 
Does not imply redundancy role. 
 
Refer Table 5 and Table 8 for a description 
of each controller state indication. 
Indicated only when in FAIL, where nnnn = 
four digit failure code. 
 
Otherwise Controller State is displayed. 
Indicates redundancy role. Refer the note. 
 
Note:  When the secondary controller is in Boot mode, the controller does not display 
BKUP because the controller does not support redundancy in that Controller State. 
Similarly, when the secondary controller is in Application mode, the controller does not 
display SEC because the BKUP Controller State implies a redundant secondary.
