Hard Drive Indicators

  1. Hard Drive Activity Indicator
  2. Hard Drive Status Indicator
  3. Hard Drive


  1. Hard Drive Activity Indicator
  2. Hard Drive Status Indicator
  3. Hard Drive Backplane on Hard Drive Tray
If the hard drive is in Advanced Host Controller Interface (AHCI) mode, the status indicator (on the right side) does not function and remains off.
Hard Drive Indicator Patterns
Drive-Status Indicator Pattern (RAID Only) Condition
Blinks green two times per second Identifying drive or preparing for removal
Off Drive ready for insertion or removal
The drive status indicator remains off until all hard drives are initialized after the system is turned on. Drives are not ready for insertion or removal during this time.
Blinks green, amber, and off Predicted drive failure
Blinks amber four times per second Drive failed
Blinks green slowly Drive rebuilding
Steady green Drive online
Blinks green three seconds, amber three seconds, and off six seconds Rebuild aborted

Power Indicators

Each AC power supply has an illuminated translucent handle and each DC power supply (when available) has an LED that serves as an indicator to show whether power is present or whether a power fault has occurred

AC Power Supply Status Indicator
Convention Power Indicator Pattern Condition
A Green The handle indicator lights up as green indicating that a valid power source is connected to the power supply and that the power supply is operational.
B Flashing green When updating the firmware of the power supply unit, the power supply handle flashes green.
C Flashing green and turns off When hot-adding a power supply, the power supply handle flashes green five times at 4 Hz rate and turns off. This indicates that the power supply is mismatched with the other power supply (in terms of efficiency, feature set, health status, and supported voltage). Replace the power supply that has the flashing indicator with a power supply that matches the capacity of the other installed power supply.
For AC power supplies, use only PSUs with the Extended Power Performance (EPP) label on the back. Mixing PSUs from previous generations of servers can result in a PSU mismatch condition or failure to power on.
D Flashing amber Indicates a problem with the power supply.
When correcting a power supply mismatch, replace only the power supply with the flashing indicator. Swapping the opposite power supply to make a matched pair can result in an error condition and unexpected system shutdown. To change from a High Output configuration to a Low Output configuration or vice versa, you must power down the system.
AC power supplies support both 220 V and 110 V input voltages with the exception of Titanium power supplies, which support only 220 V. When two identical power supplies receive different input voltages, they can output different wattages, and trigger a mismatch.
If two power supplies are used, they must be of the same type and have the same maximum output power.
Combining AC and DC power supplies is not supported and triggers a mismatch.
E Not lit Power is not connected.
