LEDs
LED colors are used consistently throughout the enclosure and its components for indicating status:
● Green – Good or positive indication
● Blinking green/amber – Non-critical condition
● Amber – Critical fault
● Blue – Controller module or IOM identification
2U enclosure LEDs
2U enclosure PCM LEDs
Under normal conditions, the power cooling module (PCM) OK LEDs will be a constant green.
