What must be replaced at the same time the backup battery is replaced?

AM.2 card and backup battery

BBoth NIC cards

CRiser card

Show Suggested Answer

Suggested Answer: A

When replacing the backup battery in a Dell PowerScale node, it is mandatory to replace the M.2 card at the same time. The M.2 card, which acts as a boot device and stores critical system information, works in conjunction with the backup battery to ensure data integrity.

Role of the Backup Battery:

Data Protection:

Provides power to preserve data in cache during a power loss.

Supports NVRAM Operations:

Ensures that any unwritten data is safely stored until power is restored.

Importance of the M.2 Card:

Boot Device:

Contains the OneFS operating system boot partition.

Data Logging:

Stores logs and system configuration data.

Simultaneous Replacement Requirement:

Interdependent Components:

The backup battery and M.2 card are designed to work together.

Preventive Maintenance:

Replacing both reduces the risk of future failures.

Firmware Compatibility:

Ensures both components are updated and compatible.

Procedure:

Shut Down the Node:

Safely power down the node before replacement.

Replace Both Components:

Remove the old backup battery and M.2 card.

Install the new components.

Reboot and Verify:

Power on the node and confirm normal operation.

Why Other Options Are Incorrect:

B . Both NIC cards:

NICs do not need to be replaced when replacing the backup battery.

C . Riser card:

The riser card is unrelated to the backup battery and does not require replacement in this context.

Dell PowerScale Reference:

Dell EMC PowerScale Field Replacement Unit (FRU) Procedure Guide:

Specifies that the backup battery and M.2 card must be replaced together.

Maintenance Best Practices:

Emphasize the importance of replacing interdependent components.

Hardware Owner's Manual:

Provides step-by-step instructions for replacing the backup battery and M.2 card.

Ugh, I'm so confused by this question. I know the backup battery is important, but I can't remember what other components are tied to it. I'll just have to read the options carefully and try to eliminate the wrong answers.

I've got a good feeling about this. The backup battery is usually related to the CMOS or RTC, so I'm thinking it's probably the M.2 card that needs to be replaced. I'll go with A.
