DR Series System NVRAM

To properly remove or replace any DR Series system hardware, you must observe and use the best practice shut down and start up procedures. For a comprehensive set of removal and replacement procedures with step-by-step instructions, see the DR Series System Owner’s Manual.

For more information about the best practices, see DR Series System: Proper Shut Down and Start Up and Shutting Down the DR Series System.

Proper shutdown and startup of the system

Proper shutdown and startup of the system

Before you attempt to remove or replace any hardware component in the DR Series system, ensure that you observe the following best practices for properly shutting down and starting up the system.

Power off the DR Series system by selecting Shutdown in the Support page of the DR Series system GUI.
For more information, see Shutting Down the DR Series System. Another method you can use to shut down the system is the DR Series system CLI command, system --shutdown.
2.
Allow the DR Series system to complete its power-down process.
When the power-down process has completed, the Power Supply status indicator is unlit.
3.
Disconnect the DR Series system power cables from the electrical power outlet.
4.
Wait an additional period of time (up to 10 minutes), and/or verify that all of the green and amber NVRAM LEDs on the rear panel of the system chassis are unlit.
 
NOTE: If you do not allow the NVRAM super capacitor sufficient time to discharge, the NVRAM status will report DATA LOSS when the DR Series system is subsequently powered up.
5.
Unlatch the latch release lock and slide the DR Series system cover back and away to gain entry to the appliance internal components.
To gain entry to the interior of the DR Series system, remove the cover. For more information, see the DR Series System Owner’s Manual.
6.
Remove and replace the system hardware components as needed.
7.
Replace the cover, and reconnect the system power cables to the electrical power outlet.
8.
Power on the DR Series system by pressing the power-on indicator/power button.

DR Series System NVRAM

DR Series System NVRAM

NVRAM Field Replacement

NVRAM is a field replaceable unit (FRU) in the DR Series system. The super capacitor that powers the NVRAM double-data rate (DDR) memory must be able to move its contents to the solid-state drive (SSD) during a power loss.

This data transfer requires maintaining the power to run the system for 3 minutes of operation (normally, it only takes approximately one minute). If a problem occurs during the data backup to the SSD, the subsequent system reboot detects this. NVRAM can experience backup failure when the following occurs:

•
The NVRAM failed to backup the data during the power shutdown
•
The super capacitor did not maintain sufficient power to backup the DDR contents into the SSD.
•
The NVRAM/SSD encountered an end-of-line (EOL) or another error.

If any of these conditions occur, the NVRAM requires either a failure recovery or a replacement.

 
NOTE: Dell recommends the following supported method for flushing DR Series system data from the NVRAM to the RAID6 before replacing the NVRAM by using either of the following DR Series system CLI commands: system --shutdown or system --reboot.
 
NOTE: If you need to remove or replace the NVRAM in the DR Series system, see Shutting Down the DR Series System and NVRAM Field Replacement.
