• Green—The server is running in normal operating
condition.
• Green, blinking—The server is performing system
initialization and memory check.
• Amber, steady—The server is in a degraded
operational state (minor fault). For example:
• Power supply redundancy is lost.
• CPUs are mismatched.
• At least one CPU is faulty.
• At least one DIMM is faulty.
• At least one drive in a RAID configuration failed.
• Amber, 2 blinks—There is a major fault with the
system board.
• Amber, 3 blinks—There is a major fault with the
memory DIMMs.
• Amber, 4 blinks—There is a major fault with the
CPUs.
