Controller Module Seven Segment Display Diagnostic Codes

The Controller Module Seven Segment Display shows the enclosure ID during normal operation. If a failure is detected, the Seven Segment Display shows a sequence of alpha numeric codes: a two digit category code and a two digit detail code. When blinking, the left display heartbeat LED indicates the controller firmware is operating correctly. When lit, the right LED shows a diagnostic code.

Controller Module Seven Segment Display Diagnostic Codes

Category	Category Code	Detail Codes
Startup error	SE	88 = Power on default dF = Power on diagnostic fault
Operational error	OE	Lx = Lockdown (x = lockdown code, refer to Lockdown code table)
Operational state	OS	OL = Offline bb = Battery backup CF = Component failure
Component failure	CF	dx = Processor/cache DIMM (x = location) Cx = Cache DIMM (x = location) Px = Processor DIMM (x = location) Hx = Host card (x = location) Fx = Flash drive (x = location)
Diagnostic failure	dE	Lx = Lock down code
Category delimiter	- (dash)	Separator between category and detail codes
End of sequence delimiter	Blank	End of sequence indicator

ESM Seven Segment Display Diagnostic Codes

The ESM Seven Segment Display displays the chassis ID (numeric character) during normal operation. It shows diagnostic codes (alpha character) during ESM firmware initialization or if a failure is detected. When blinking, the leftmost display's decimal point indicates the ESM firmware is operating correctly. When lit, the rightmost display's decimal point indicates a diagnostic code is displayed.
