T3 LEDs - Understanding What They Mean

In general any fault status will be shown by a flashing amber LED. A solid amber LED implies a download or upgrade in progress while a solid green LED indicates normal operation. Here are the specific codes for each LED type. All of these assume power is on, unless indicated.

Controller

Controller LED	Controller Status
off	bootmode-none at EEPROM level Controller is not installed or recognized
solid green	Controller OK
solid amber	Controller boot, shutdown, or firmware download in progress
blinking amber	Controller failed to initialize, no boot code, hardware fault or failure; replace controller Note: Verify a controller card failure using the CLI or Component Manager.

FC-AL

Fibre Channel LED	Fibre Channel Status
off	Fibre Channel disabled
solid green	Fibre Channel enabled and inactive
blinking green	Fibre Channel enabled and active

Interconnect Card

IC Status LED	Current Status
off	IC not installed or recognized
solid green	IC OK Cable OK (if present)
blinking green	IC OK Cable bad
solid amber	IC firmware download in progress
blinking amber	IC hardware fault or failure, replace IC Note: Verify an interconnect card or cable failure using the CLI or Component Manager.

Power and Cooling Unit

AC Status LED	PS OK Status LED	Status
off	off	Power is off No AC power present
solid amber	off	Power is off Power Switch turned off AC Power is available
solid green	solid green	Normal Operating State: PCU receiving AC Power switch turned on AC power available
solid green	off	Occurs when disk tray is shut down: PCU disabled AC power is available
solid amber	solid amber	PCU is off; disk tray willpower off after PCU is disabled
solid green	solid amber	Indicates one or more of the following: Over temperature condition; PCU disabled DC power not available; PCU disabled Both fans have fault; PCU disabled Battery on refresh cycle
solid green	blinking green	Battery not OK * (See NOTE below)
solid green	blinking amber	Indicates one or more of the following: PCU disabled One fan fault Battery hold time low; PCU remains enabled Battey out of warranty; PCU remains enabled Battery life span failure; PCU remains enabled Note: Verify a power and cooling unit failure using the CLI or Component Manager.

* NOTE: If power was lost, you may see this LED pattern while the battery recharges. If 'refresh -s' shows a status of "BAT Low", give it ~12 hours to return to "NORMAL" status before replacing it. You can also see this pattern during a normal scheduled battery refresh.

Disk Drive

Drive Activity	Drive Status	Status
off	off	Drive not installed or recognized
blinking green	off	Drive spin up or spin down
solid green	off	Drive ok and idle
blinking green	off	Drive ok and active
N/A	solid amber	Drive reconstruct Firware download in progress
N/A	blinking amber	Drive failure, replace drive Note: Verify a drive failure using the CLI or Component Manager.
