Dell EMC PowerVault ME484 - ME484 JBOD Status Indicators (LEDs); Expansion Module and Disk LEDs

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
Topics:
• ME484 JBOD storage enclosure LEDs
• 12 Gb/s expansion module LEDs
• DDIC LEDs
• Drawer LEDs
• Fan cooling module LEDs
• Ops panel
• PSU LEDs
ME484 JBOD storage enclosure LEDs
When the ME484 JBOD storage enclosure is powered on, all LEDs turn on for a short period to ensure that they are working.
NOTE:
This behavior does not indicate a fault unless LEDs remain lit after several seconds.
12 Gb/s expansion module LEDs
ME484 JBOD storage enclosures are configured with dual expansion modules.
