Sun Microsystems 220R manual

Removing and replacing a power supply can only be performed by a qualified service provider. For information about removing and installing power supplies, see the Sun Enterprise 220R Server Service Manual.

Power supplies in a redundant configuration feature a hot-swapcapability. This means that you can remove and replace a faulty power supply without turning off the system power or even shutting down the operating system.

Caution –When removing a hot-swappable power supply, do not disengage and reengage the supply in rapid succession. Always remove a supply completely before reinserting the same supply or a replacement supply. Rapid seating and unseating of power supplies may result in false error conditions.

Three LED indicators on the front of the power supply display AC and DC status, and fault conditions. For additional details, see “Power Supply LEDs” on page 141.

Note –Sun Enterprise 220R power supplies will shut down automatically in response to certain over-temperature and power fault conditions. To recover from an automatic shutdown, you must disconnect the AC power cord, wait roughly 10 seconds, and then reconnect the power cord.
