Caution – The CPU/Memory board weighs approximately 17-22 pounds (7-10 kilograms) and is

heavy. Take care when removing the board from the system.

Note – A CPU/Memory board field-replaceable unit (FRU) is for maintenance use only. FRUs must not be used

to upgrade CPU performance in systems. Such usage can violate United States export regulations.

You can insert the CPU/Memory board into a powered-on system. However, the board is not recognized by the
system until the domain has been dynamically reconfigured to include the board, or the domain is re-initialized
and rebooted. For complete procedures for re-initializing a domain, refer to the system administration manual
for your product.

Preparing to Install a CPU/Memory Board

If you are installing an UltraSPARC®IV/IV+ CPU/Memory board in a Sun Fire™E25K/E20K, Sun Fire 15K/
12K, Sun Fire E6900/E4900 or a Sun Fire 6800/4800 system, additional upgrades may be required for hardware,
software, and firmware. Refer to the applicable Sun Fire High-End and Midrange Systems CPU/Memory Board
Upgrade Requirements document at http://sun.com/documentation.

Caution – The Sun Fire E25K/E20K, Sun Fire 15K/12K, Sun Fire E6900/E4900 and Sun Fire

6800/4800 systems might shut down if you do not install the additional upgrades that are required for
the UltraSPARC IV/IV+ CPU/Memory boards.

If your system requires an OS upgrade and SC firmware upgrade, upgrade the firmware first. Install the new
CPU/Memory board only after you have upgraded the firmware and software.

Note – UltraSPARC IV/IV+ CPU/Memory boards are not supported in Sun Fire 4810/3800 systems.

1. Place an ESD mat close to the system.

2. Wear an ESD strap and connect it to the system.

3. Place the new CPU/Memory board on the ESD mat.

4. Inspect the connector on the new board being installed.

a. Remove the protective cover from the board connector.

b. Check to see if the plastic is deformed or damaged, including both the pin holes and the fins.

c. Insure there are no major (out of the normal) gaps between each pin row.

5. Insure the CPU/Memory board alignment tabs are not bent.

a. Check the CPU/Memory board springfingers for damage.

b. Check the springfingers on the empty slots that will receive the new boards for damage (SB5 for Sun

Fire E6900 and Sun Fire 6800 systems and SB4 for Sun Fire E4900 and Sun Fire 4800 systems).

6. Make sure that the new CPU/Memory board ejector levers are 90 degrees straight out from the board.
