beyond tolerable limits.
Root Causes • FCB hardware is not handling the voltage correctly.

Service Resolution
Steps
Perform DR073 - Resolve FC I/O Blade Voltage Alarm
on page 399.
Note: If there are other active voltage/power-related tickets, the problem may
be caused by the power supply to the library, so you can dispatch a power
supply; otherwise, the only CRU/FRU you should dispatch is the
FC I/O blade.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
Dispatch the first part listed below for replacement. If this does not solve the
problem, dispatch the second part, and so on, in order. Dispatch only one part
(or set of parts) at a time.
1 FC I/O Blade
2 Power Supply (only dispatch if warranted; see note in Service Resolution
Steps above)
