PSU Replacement
Considerations
Before you begin a PSU replacement, review the following information:
• PSUs are a hot-swappable component. You do not need to stop I/O
from coming in and out of the system or remove power from the
system to replace a PSU.
• Take ESD precautions when replacing a PSU. For more information,
review ESD Precautions on page 68.
Identify a Failed PSU
At the rear of the F2000, locate the failed PSU by identifying the PSU
with the illuminated amber PSU Fault LED (see Figure 145 on page 142).
