Figure 2. Front-Panel Features and Indicators—Dell EMC PowerVault MD3820i Figure 3. Front-Bezel Features and Indicators Table 1. Front-Panel Features and Indicators Item Indicator, Button, or Connector Description 1 Enclosure status LED The enclosure status LED lights when the enclosure power is on. Lights blue during normal operation. Blinks blue when a host server is identifying the enclosure or when the system identification button is pressed. Lights amber as enclosure boots or is reset.
Table 1. Front-Panel Features and Indicators (continued) Item Indicator, Button, or Connector Description Blinks amber when the enclosure is either in a fault state or the hosts are not using the preferred path to a virtual disk. For more information about diagnosing the issue, see Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide. 2 Power LED The power LED lights green when at least one power supply is supplying power to the enclosure.

2 Controller Modules Topics: • • • • RAID Controller Modules RAID Controller Module Connectors And Features RAID Controller Module—Additional Features Cache Functions and Features RAID Controller Modules The RAID controller modules provide high-performance, advanced virtual disk configuration, and fault-tolerant disk subsystem management. Each RAID controller module contains 4GB or 8GB of mirrored cache for high availability and a battery-powered cache offload mechanism.
Table 4. RAID Controller Module Connectors And Features (continued) Item Component Function 2 Seven segment display sequence Displays status or error codes for the storage array. 3 Controller power LED Lights green when controller power is on. Turns off when controller is not powered. 4 Controller fault LED Lights amber when controller fault is detected. Turns off when controller is operating normally.
NOTE: For virtual disks, the RAID controller firmware changes the data cache setting based on the state of the battery. If the battery is missing or does not have sufficient charge, the controller flushes the cache and sets the write cache attribute to Write Through for all virtual disks. When the battery is replaced, Write Back is re-enabled. Storage Array Thermal Shutdown The system automatically shuts down when system temperature exceeds the safe threshold.
The RAID controller automatically switches to write-through if cache mirroring is disabled, or if the battery is missing, or has a fault condition.

CAUTION: It is recommended that you turn off the host server before turning off the expansion enclosure array to prevent loss of data. If EMM Status LED is Blinking Amber at Five Times per Sequence Update the firmware to the latest supported firmware on both the EMMs. For more information on updating your EMM firmware, see Management Firmware Downloads in the Storage Arrays Administrator's Guide at dell.com/powervaultmanuals.
7. Replace the RAID controller module. 8. Turn on the host server. If the problem is not resolved, see Getting Help. If the Link Status LEDs are not Green 1. Turn off the host server. 2. Reseat the cables on the expansion array and the server. 3. Turn on the expansion arrays and the storage array and wait until the system is fully booted. 4. Turn on the host server. 5. Check the link status LED. If the link status LED is not green, replace the cables. If the problem is not resolved, see Getting Help.
Troubleshooting a Wet System CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product. 1.
5. Close the system. 6. Run the appropriate diagnostic test. For more information, see Using System Diagnostics. If the tests fail, see Getting Help. Controller failure conditions Certain events can cause a RAID controller module to fail and/or shut down. Unrecoverable ECC memory or PCI errors, or critical physical conditions can cause lockdown. If your RAID storage array is configured for redundant access and cache mirroring, the surviving controller can normally recover without data loss or shutdown.
PCI errors The storage array firmware can detect and only recover from PCI errors when the RAID controller modules are configured for redundancy. If a virtual disk uses cache mirroring, it fails over to its peer RAID controller module, which initiates a flush of the dirty cache.
