Replacing The Secc Version - NEC NEAX Express Service & Reference Manual

Replacing the SECC Version

If the system has been running, any processor and heat sink
already installed on the board will be hot. To avoid the
possibility of a burn, let the components cool for 10 minutes
before continuing with the procedures described here
1. Power off the system and remove the left side panel as described earlier in
this chapter.
Observe static precautions. Use an antistatic wrist strap.
Hold the processor only by its edges.
2. If your system has one processor and you would like to add a second
processor, contact your Service Representative for assistance.
3. If your system has one processor and you are replacing it, leave the
termination board intact in the empty secondary processor connector.
Remove the processor you want to replace.
4. If your system has two processors and you are replacing one or both, remove
the appropriate one(s).
5. Press the processor latches toward the center of the SEC cartridge to free
them from the retention module (see A in Figure "Removing a Processor").
6. Lift the SEC cartridge upward, out of the retention module.
7. Put the processor in a piece of conductive foam and store in an antistatic
package.
