Drawer LEDs
The following table describes the LEDs on the drawers:
Table 17. Drawer LED descriptions
LED Status/description
Sideplane OK/Power Good Green if the sideplane card is working and there are no power problems.
Drawer Fault 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.
Logical Fault Amber (solid) indicates a disk fault. Amber (blinking) indicates that one or more storage systems are in
an impacted state.
Cable Fault Amber indicates the cabling between the drawer and the back of the enclosure has failed. Contact
your service provider to resolve the problem.
Activity Bar Graph Displays the amount of data I/O from zero segments lit (no I/O) to all six segments lit (maximum I/O).
DDIC LED
The DDIC supports LFF 3.5" and SFF 2.5" disks as shown in Figure 7. 3.5" disk drive in a DDIC on page 13 and Figure 8. 2.5" drive in a 3.5"
DDIC with a hybrid drive carrier adapter on page 14). The following figure shows the top panel of the DDIC as viewed when the disk is
aligned for insertion into a drawer slot.
