S
• The fan speed has fallen below the minimum allowed RPM for a fan.
Power Supply LEDs (9020, 9040, 9080, 9120 and 9240)
Each power supply has two LEDs: DC OK and AC OK. Following are the status
definitions for each.
DC OK
• Green indicates that DC power is normal.
• Off indicates a DC power failure or no DC power is present.
AC OK
• Green indicates that AC power is normal.
• Off indicates a AC power failure or no AC power is present.
Module LEDs (9020, 9040, 9080, 9120 and 9240)
Leaf Module/FVIC/EVIC IB Port LEDs
Each module IB port has a Blue IB link status LED that provide the following
indications:
• On - the logical link is up (port is in the Active state).
• Off - the physical link is down (port is in the Down state).
Module Status LED
The status LED indicates one of the following conditions:
• Steady Green - the module is operating normally.
•Blinking Green - LED test state.
• Off - module is in the removable state.
Module Attention LED
The Attention LED indicates one of the following conditions:
• Off - the system functioning normally.
• Steady Amber - the system requires some attention, which could indicate one
of the following conditions:
• The switch temperature is at a warning level on the module.
• The switch silicon temperature is at a warning level (approximately 90 degrees
C).
• DC voltages on the board are slightly out of tolerance (12V Bulk, 5V, 3.3V,
1.8V, VBIO are all monitored).
• The module can no longer function properly. The system will take the
appropriate actions to ensure that no damage is done to its components.
