5. Pull the cam handle downward and begin to slide the controller module out of the chassis.
Make sure that you support the bottom of the controller module as you slide it out of the chassis.
Step 3: Replace the NVMEM battery
To replace the NVMEM battery in your system, you must remove the failed NVMEM
battery from the system and replace it with a new NVMEM battery.
1. Check the NVMEM LED:
◦ If your system is in an HA configuration, go to the next step.
◦ If your system is in a stand-alone configuration, cleanly shut down the controller module, and then
check the NVRAM LED identified by the NV icon.
The NVRAM LED blinks while destaging contents to the flash memory when you halt the
system. After the destage is complete, the LED turns off.
▪ If power is lost without a clean shutdown, the NVMEM LED flashes until the destage is complete,
and then the LED turns off.
▪ If the LED is on and power is on, unwritten data is stored on NVMEM.
This typically occurs during an uncontrolled shutdown after ONTAP has successfully booted.
2. Open the CPU air duct and locate the NVMEM battery.
