Replacing A Hot-Swap Power Supply - IBM System x3300 M4 Installation And Service Manual

Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which might
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when you work
inside the server with the power on.
2. If only one power supply is installed, turn off the server and peripheral devices
and disconnect all power cords.
3. Press the release latch on the hot-swap power supply and pull it out from the
server.
4. If you are instructed to return the power supply, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to
you.

Replacing a hot-swap power supply

The following notes describe the type of power supply that the server supports
and other information that you must consider when you replace a power supply:
v To confirm that the server supports the power supply that you are installing, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
v Before installing an additional power supply or replace a power supply with one
of a different wattage, the user may use the IBM Power Configurator utility to
determine current system power consumption. For more information and to
download the utility, go to http://www-03.ibm.com/systems/bladecenter/
resources/powerconfig.html
v The server comes with one hot-swap 12-volt output power supply that connects
to power supply bay 1. The input voltage is 100 - 127 V ac or 200 - 240 V ac
auto-sensing.
v Power supplies in the server must be with the same power rating or wattage to
ensure that the server will operate correctly.
v Power supply 1 is the default/primary power supply. If power supply 1 fails,
you must replace the power supply with the same wattage immediately.
v The user can order an optional power supply for redundancy.
v These power supplies are designed for parallel operation. In the event of a
power-supply failure, the redundant power supply continues to power the
system. The server supports a maximum of two power supplies.
