Note:
0.01 mL is one tick mark on the syringe. If the grease is properly applied, approximately half
(0.22 mL) of the grease will remain in the syringe.
Step 6.
Install the heat sink onto the microprocessor as described in “Installing a microprocessor and
heat sink” on page 288.
Installing a hot-swap power supply
Use this information to install a hot-swap power supply.
The following notes describe the type of ac power supply that the server supports and other information that
you must consider when you install a power supply:
• Make sure that the devices that you are installing are supported. For a list of supported optional devices
for the server, see http://www.lenovo.com/ serverproven/.
• Before you install an additional power supply or replace a power supply with one of a
different wattage, you may use the Lenovo Power Configurator utility to determine current
system power consumption. For more information and to download the utility, go to
http://www.ibm.com/systems/bladecenter/resources/powerconfig.html.
• The server comes with one hot-swap 12-volt output power supply that connects to power supply bay 1.
The input voltage is 110 V ac or 220 V ac auto-sensing.
• Power supplies in the server must be with the same power rating or wattage to ensure that the server
will operate correctly.
• 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.
• You can order an optional power supply for redundancy.
• 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.
