8.3.1 Seven-segment display sequence codes
Seven-segment display sequences enable you to understand errors and operational states of
the various components in your storage array. Each sequence shows a two-digit category
code, followed by a two-digit detail code. The category code appears at the start of a
sequence and the detail code follows the category code with more specific information about
the error. After each category code is displayed, the LED goes blank. Then the detail code
appears and disappears, and the entire sequence is repeated. For example, if there is a
power-on validation error during startup, you see the following codes displayed on the seven-
segment display: SE, followed by Sx, in which SE is the category code and Sx is the detail
code.
When the seven-segment display sequence starts, the Diagnostic LED is on (green).
The following table includes the seven-segment display sequence codes and descriptions:
Category Category code Detail code
Startup error SE – 88: Power-on default
– dF: Power-on diagnostic fault
– Sx: Power-on validation error
Operational error OE – Lx: Lock-down codes
See Seven-segment display lock-down
codes.
Operational state OS – OL: Offline
– bb: Battery backup (operating on
batteries)
– OH: CPU temperature exceeds the
warning level
– CF: Component failure
Component failure CF – dx: Processor or cache DIMM
– Cx: Cache DIMM
– Px: Processor DIMM
– Hx: Host interface card
– Fx : Flash drive
– bl: Base controller card
Diagnostic failure dE – Lx: Lock-down codes

down codes.
