Table 17. FCM LED descriptions
LED Status/description
Module OK Constant green indicates that the FCM is working correctly. Off indicates that the fan module
has failed. Follow the procedure in “Replacing an FCM” in the Dell EMC PowerVault ME4
Series Storage System Owner’s Manual.
Fan Fault Amber indicates that the fan module has failed. Follow the procedure in “Replacing an FCM” in
the Dell EMC PowerVault ME4 Series Storage System Owner’s Manual.
5U Ops panel LEDs
The Ops panel displays the aggregated status of all the modules.
Table 18. Ops panel LED descriptions
LED Status/description
Unit ID display Usually shows the ID number for the enclosure, but can be used for other purposes, for
example, blinking to locate enclosure.
Power On/Standby Amber if the system is in standby. Green if the system has full power.
Module Fault Amber indicates a fault in a controller module, IOM, PSU, or FCM. Check the drawer LEDs for
indication of a disk fault. See also Drawer Fault LEDs (amber) on page 73.
Logical status Amber indicates a fault from something other than firmware (usually a disk, an HBA, or an
internal or external RAID controller). Check the drawer LEDs for indication of a disk fault. See
also 5U drawer LEDs on page 78.
Drawer 0 Fault Amber indicates a disk, cable, or sideplane fault in drawer 0. Open the drawer and check DDICs
for faults.
Drawer 1 Fault Amber indicates a disk, cable, or sideplane fault in drawer 1. Open the drawer and check DDICs
for faults.
5U drawer LEDs
The following table describes the LEDs on the drawers:
Table 19. 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).
5U DDIC LED
The DDIC supports LFF 3.5" and SFF 2.5" disks as shown in 3.5" disk drive in a DDIC on page 13 and 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.
