Types of expansion adapters

The following list specifies the expansion adapters that the C1200 and C2100 can use:

Note
The NVRAM 4 adapter is only used in the C2100.

NVRAM 4 adapter
The NVRAM 4 adapter has an attached, sealed, lithium-ion battery that is recharged whenever the system is turned on and operating normally. The NVRAM 4 adapter also contains the CompactFlash^TM card, which is used during system boot. This card contains the most recently downloaded versions of Data ONTAP^TM software, system diagnostics, and boot files.

Replace the NVRAM 4 adapter only if the following situations occur:
- The battery continues to read low after 24 hours of normal system operation.
- The system does not boot, or you receive warning messages during boot that the CompactFlash card is invalid or damaged.
- Diagnostic tests indicate a problem with the NVRAM 4 adapter that requires replacing it.
  Note
  When replacing the NVRAM 4 adapter, you must reinitialize the CompactFlash card. See Updating software and firmware and the Software Setup Guide for instructions about how to perform this task.
