Failing function codes:
Failing function codes (FFCs) identify a function within the system unit that is failing.
Table 16 describes the component that each function code identifies.
Note: When replacing a component, perform system verification for the component. See “Using the
diagnostics program” on page 455.

1. Battery
Note: After replacing the battery:
a. Set the time and date.
b. Set the network IP addresses (for compute nodes that start up from a network).
2. System-board and chassis assembly
