Non-Volatile Memory

The memory supports up to:
• three stored system images (not including recovery image)
• one week of log files at normal verbosity; and one day of log files at maximum verbosity

Vital Product Data Storage

Vital Product Data (VPD) is stored in non-volatile memory in the Chassis ID module (refer to “Chassis
ID Module” on page 19) and the Fabric Controller that is installed in the Core slot (refer to “Fabric
Controller Modules” on page 18), and is available electronically. Some VPD info can be accessed via
CLI, the Java GUI, or the Web GUI.
The following Vital Product Data can be recovered by returning a Field Replaceable Unit to the original
manufacturer. Note: This requires the appropriate support contract.
• Power on hours
• Manufacturing part number
• Serial number
• Final test date
•Card ID
• Failure code
• Failure date
• Operation status
•Failure log
• OEM part number

Diagnostics

Refer to “About Diagnostic Tests” on page91 for more detailed information.
The following tests are run to determine operational status:
• Power On Self Test (POST) is performed on all system components during power on to determine
operational readiness.
• Redundant components' operational status is ensured periodically during normal operation,
including the logic required to perform the transition from faulted/primary to redundant
component. Detection of abnormal status is reported.
