Installing power supply components Installing power supply components Replacing a hot-swap power supply Your server uses 430 W hot-swappable power supply modules. If your server has all three power supply modules installed, the modules act as redundant, hot-swappable power supplies. If one of the three power supplies fails, the other power supplies support the server while you replace the failed power supply. You do not need to turn off the server or disconnect peripheral devices to replace a failed redundant power supply. Warning If only two power supplies are installed (non-redundant), you must turn off all power to the server before replacing a power supply. The power supplies in this server contains no user-serviceable parts. Only a qualified computer technician should service the power supplies. Your server comes with 3-wire AC power cords fitted with the correct plug style for your region. If this plug does not match the connector on your UPS or wall outlet, do not attempt to modify the plug in any way. Use a UPS or wall outlet that is appropriate for the supplied AC power cords. To replace a power supply: 1 If only two power supplies are installed, follow the instructions in "Preventing static electricity discharge" on page 36. Make sure that you turn off the server, then unplug the power cords and all other cables connected to the server. 2 Remove the front cover, if installed. For instructions, see "Using the front cover" on page 39. 3 Identify the failed power supply. On a failed power supply, the power supply's LED is off. www.gateway.com 47
