3.4 Servicing Power Supplies
Some versions of the Sun Fire X4140 Servers are equipped with redundant
hot-swappable power supplies. Redundant power supplies enable you to remove
and replace a power supply without shutting the server down, if the other power
supply is online and working.
If a power supply fails and you do not have a replacement available, leave the failed
power supply installed to ensure proper air flow in the server.
See Section 3.4.2, “Power Supply LED Reference” on page 3-14 for specific
information about power supply status LEDs.
The following topics are covered:
■
