Preparing To Install A Cpu/Memory Board; Inspecting The New Cpu/Memory Board - Sun Microsystems Sun Fire E25K Installation Manual

Caution – The CPU/Memory board is heavy and weighs approximately 17-22 pounds (7-9
kilograms). 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 will not be recognized
by the system until the domain has been dynamically reconfigured to include the board, or re-initialized and
rebooted. Refer to the dynamic reconfiguration manual for your product for complete DR procedures or the
system administration manual for your product for complete procedures for re-initializing a domain.

Preparing to Install a CPU/Memory Board

Note –
If you are installing an UltraSPARC
additional upgrades are required for hardware, software, and firmware. Refer to the accompanying document,
"Sun Fire High-End and Midrange Systems UltraSPARC IV CPU/Memory Board Upgrade Requirements" for
the current upgrade requirements.
Caution – The Sun Fire 6800/4800 system might shut down if you do not install the additional
upgrades that are required for the UltraSPARC IV CPU/Memory boards.
Note –
If your system requires a software upgrade and a firmware upgrade, upgrade the firmware first.
Upgrade the software second. Install the new CPU/Memory board only after you have upgraded the
firmware and software.
Note – UltraSPARC IV CPU/Memory boards are not supported in Sun Fire™ 4810/3800 systems. Only earlier
versions of CPU/Memory boards are 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. Inspect the new CPU/Memory board before inserting it into the system:
a. Inspect the connector on the board being installed.
Remove the protective cover from the board connector. Check to see if the plastic is deformed or
damaged, including both the pin holes and the fins. Insure there are no major (out of the normal) gaps
between each pin row.
