Step 2: Replace or add a caching module
The NVMe SSD Flash Cache modules (FlashCache or caching modules) are separate
modules. They are located in the front of the NVRAM module. To replace or add a
caching module, locate it on the rear of the system on slot 6, and then follow the specific
sequence of steps to replace it.
Before you begin
Your storage system must meet certain criteria depending on your situation:
• It must have the appropriate operating system for the caching module you are installing.
• It must support the caching capacity.
• The target node must be at the LOADER prompt before adding or replacing the caching module.
• The replacement caching module must have the same capacity as the failed caching module, but can be
from a different supported vendor.
• All other components in the storage system must be functioning properly; if not, you must contact technical
support.
Steps
1. If you are not already grounded, properly ground yourself.
2. Locate the failed caching module, in slot 6, by the lit amber Attention LED on the front of the caching
module.
3. Remove the caching module:
If you are adding another caching module to your system, remove the blank module and go
to the next step.
