Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective package until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
Limit your movement. Movement can cause static electricity to build up around
you.
Handle the device carefully, holding it by its edges or its frame.
Do not touch solder joints, pins, or exposed printed circuitry.
Do not leave the device where others can handle and possibly damage the
device.
While the device is still in its static-protective package, touch it to an unpainted
metal part of the system unit for at least two seconds. (This drains static
electricity from the package and from your body.)
Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If your device is an adapter, place it component side
up.) Do not place the device on your system unit cover or on a metal table.
Take additional care when handling devices during cold weather because
heating reduces indoor humidity and increases static electricity.

The memory controller provides ECC support for up to 32 industry-standard,
168-pin, single connector, 8-byte, dual inline memory modules (DIMMs).
Note: To verify the correct amount of memory installed in your server, review
the information on the Logo screen during system startup. The
operating system might not reflect the correct amount of memory.
Advanced System Management support
With the Advanced System Management service, you can configure system
management events, such as power-on self-test (POST), loader, and
operating-system timeouts or critical temperature, voltage, and tamper alerts.
The Advanced System Management PCI adapter generates all alerts, timeouts,
and other system management information. The adapter then forwards this
information to other systems on the Ethernet or Token-Ring network (or uses its
modem to forward this data using a serial connector).
For more information on the features and functions of the Advanced System
Management PCI adapter, refer to the documentation provided with your
system-management software.
For an illustration of the Advanced System Management PCI adapter, see
“Advanced System Management PCI adapter component locations” on
page 101.

Power supplies
Your server comes with three hot-swap power supplies. The power supplies can
provide up to 550 watts each at 110 V ac input power, and 750 watts each at 220
V ac input power.
13
DANGER
Overloading an electrical circuit breaker is potentially a fire
hazard and a shock hazard under certain conditions. To avoid
these hazards, adhere to the instructions in the following
statements.
1. If you are connecting to a 100–127 V ac power source,
connect each power cord to a separate branch circuit.
2. If you are connecting to a 200–240 V ac power source and
the branch circuit breaker rating is:
a. 13 amps or less, connect each power cord to a separate
branch circuit.
b. 14 amps to 19 amps, do not connect more than two
power cords to the same branch circuit.
c. 20 amps or greater, you may connect up to three power
cords to the same branch circuit.
In addition to the power supplies, your server comes with three 220 V ac power
cords, and three 110 V ac power cords (U.S. only). Be sure to select the
appropriate power cord voltage for your server environment. All three power cords
must have the same voltage.
If you connect all three power cords of the same voltage to the power supplies, the
three power supplies support redundancy and hot-swap capability.
For servers with redundant power, the loss of a single power supply will not affect
the server operation. Replace a power supply that has failed as soon as
convenient to help maintain the redundant power and cooling capability. When a
power supply has failed and the Power Good light is on, the dc power LED on the
power supply is off. See “Power supply LEDs” on page 156 for more information
on the dc power LEDs. See “Replacing a hot-swap power supply” on page 84 for
complete details on the power supplies.
Attention: To ensure proper server operation, be sure to connect all three 220 V
ac power cords or all three 110 V ac power cords to the power supplies.
