• Fast Blink - IB data is flowing through the port.
• Off - the physical link is down (port is in the Down state).
Spine and Leaf Module Status LED
The status LED indicates one of the following conditions:
• Steady Green - the module is operating normally.
• Blinking Green (twice per second) - transitional to the removal state.
• Blinking Green (once every four seconds) - LED test state.
• Off - module is in the removable state.
Spine and Leaf 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.
• Blinking Amber (once every four seconds) - LED test state.
Spine Module Management LEDs
Each SFS 7012 spine module has three management LEDs:
• Capable:
–
Green indicates that the spine slot supports management.
–
Off indicates that the spine slot does not support management.
• Stat:
–
Green indicates that a management board is present.
–
Off indicates that no management board is present.
• Act:
–
Green indicates that management board is in the active mode.
–
Off indicates that the management board is in the standby mode (if the STAT LED is Green).
• DDR:
–
Green indicates that the switch is capable of running at DDR speeds.
–
Off indicates that the switch is not capable of running at DDR speeds (i.e., SDR only).
