Chapter 6 Checking LEDs

A similar situation occurs when you add an expansion unit or JBOD and there is a 
mismatch between the SES or PLD firmware of the RAID array and that of the 
expansion unit, or between two expansion units.

See  “Upgrading SES and PLD Firmware” on page 7-8 for information about 
upgrading SES and PLD firmware.

Back-Panel LEDs

The back-panel LED colors indicate the conditions described in the following figures 
and tables. 

To test that the LEDs work, using a paper clip, press and hold the Reset button 

for 5 seconds. All the LEDs should change from green to amber when you perform this 
test. Any LED that fails to light indicates a problem with the LED. When you release 
the Reset button, the LEDs return to their initial state.
