*If multiple conditions occur simultaneously, the LED state behaves as indicated in the previous table.
Each DDIC has a single Drive Fault LED. If the Drive Fault LED is lit amber, a disk fault is indicated. If a disk failure occurs, follow the

66 Troubleshooting and problem solving
Status/description
Green if the sideplane card is working and there are no power problems.
Amber if a drawer component has failed. If the failed component is a disk, the LED on the failed DDIC
lights amber. Follow the procedure in "Replacing a DDIC" in the Dell EMC PowerVault ME4 Series
Storage System Owner's Manual. If the disks are OK, contact your service provider to identify the
cause of the failure, and resolve the problem.
Amber (solid) indicates a disk fault. Amber (blinking) indicates that one or more storage systems are in
an impacted state.
Amber indicates the cabling between the drawer and the back of the enclosure has failed. Contact
your service provider to resolve the problem.
Displays the amount of data I/O from zero segments lit (no I/O) to all six segments lit (maximum I/O).
