Working with Microprocessor Upgrades
Ÿ To avoid damaging the microprocessor or socket during
installation, make sure that the socket latch is fully opened to
the vertical position before you insert the microprocessor.
Ÿ The fan sink clip is under tension. Be careful when installing or
removing the microprocessor assembly. Do not let the clips
scrape against the processor board, sockets, or other
components.
Ÿ
If you select a setting for the frequency jumper (the J17/J18
jumper block) that is greater than the actual frequency of the
microprocessor, you might damage the microprocessor.
Notes:
1. The illustrations in this section might differ slightly from your
hardware.
2. To avoid damage and ensure proper server operation when you
install a new or additional microprocessor, use the same speed
and voltage requirements as those of the currently installed
microprocessor. Microprocessor internal and external clock
frequencies must be identical.
3. To order additional microprocessors, contact your IBM
marketing representative or your IBM reseller.
4. When you install a second microprocessor, it becomes the
startup (boot) microprocessor.
5. The pins on the microprocessor are delicate and susceptible to
damage from static electricity and physical mishandling. Do not
touch or bend the exposed pins. Protect the pins while carrying
the microprocessor and during installation.
