Installing a fixed power supply
The following notes describe the type of power supply that the server supports
and other information that you must consider when you install 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 replacing 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 input voltage is 100 - 127 V ac or 200 - 240 V ac auto-sensing.
Statement 8
CAUTION:
Never remove the cover on a power supply or any part that has the following
label attached.
Hazardous voltage, current, and energy levels are present inside any component
that has this label attached. There are no serviceable parts inside these
components. If you suspect a with one of these parts, contact a service
technician.
To install a fixed power supply, complete the following steps:
Note: You must install the fan assembly before removing or installing the power
supply.
1. Read the safety information that begins in Safety and “Installation guidelines”
on page 36.
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. Turn off the server (see “Turning off the server” on page 24) and all attached
peripheral devices. Disconnect the power cord; then, disconnect all external
cables from the server.
3. Unlock and remove the left side cover (see “Removing the left-side cover” on
page 39).
4.
Remove the air baffle (see “Removing the air baffle” on page 41).
5. Touch the static-protective package that contains the fixed power supply to
any unpainted metal surface on the server; then, remove the power supply
from the package and place it on a static-protective surface.
