2 Controller modules RAID controller modules RAID controller modules provide high-performance, advanced virtual disk configuration, and fault-tolerant disk subsystem management. Each RAID controller module contains 4 GB of mirrored cache for high availability and is protected by a battery powered cache offload mechanism. NOTE: 8 GB mirrored cache is an optional feature.
Table 5.

NOTE: The password reset switch is not available if your system was shipped after September 2015. The password reset switch functionality was disabled starting from controller firmware 08.20.09.60 and later versions.
MD3060e expansion module features and indicators Figure 9. MD3060e expansion module features and indicators Table 6.

NOTE: For virtual disks, the 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.

Physical-disk drawers Each storage array contains five physical-disk drawers. Each physical-disk drawer supports up to 12 hot-swappable physical disks. NOTE: You can open only one physical-disk drawer at a time. If you attempt to open more than one drawer, it may cause unexpected results. Figure 13.

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.
CAUTION: Do not try to remove more than one drawer at a time. Ensure that you insert the drawer that is out completely before pulling out another drawer. NOTE: Note and save the location of the physical disks before removing the physical disks from the physical-disk drawer. NOTE: The physical-disk drawers are not hot-swappable. Replacing a physical-disk drawer causes all the physical disks in the replaced drawer to be unavailable to the controllers in the storage subsystem.
3. Install the physical disks row wise into the physical-disk drawer. NOTE: Using the note that you saved while removing the physical-disk drawer, install the physical disks to the same location in the physical-disk drawer that they were in. 4. Close the physical-disk drawer. 5. Install the SAS chain cables. NOTE: Make sure all the SAS chain cables are firmly connected to all the drawers. 6. Install the front bezel. 7.

CAUTION: Do not plug the enclosure into a standard power outlet. Your storage array is shipped with two IEC C19 to C20 jumper cables. Connect the C19 plug to the array’s power supplies and the C20 plug to the power distribution unit (PDU) in the rack cabinet. For power redundancy, split the power connections from each enclosure into separate PDUs and connect the PDUs to external power receptacles on different circuits. The enclosure supports only 200 V to 240 V input sources.

If EMM status LED is blinking amber (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 Dell EMC PowerVault MD Series Storage Arrays Administrator's Guide at Dell.com/powervaultmanuals. If the EMM status LED is solid or blinking amber (2 or 4 times per sequence) 1. Turn off the host server. 2.
3. Turn off the host server, storage array, and expansion enclosures. 4. Reseat the RAID controller module and reconnect cables on the storage array and the host server. 5. Turn on the expansion arrays and then the storage array and wait until the system is fully booted. 6. Turn on the host server. 7. Check the LEDs of all cabled ports. Replace the fibre optic cables of any port(s) where both LEDs are unlit. If the problem is not resolved, see Getting Help.
Critical conditions The storage array generates a critical event if the RAID controller module detects a critical condition that could cause immediate failure of the array and/or loss of data.
