Once the jumper is in the ON position, proceed with the installation or
removal as described in the preceding sections.
Caution – After you turn the battery ON do not move or remove the jumper.
Moving the jumper will cause the lose of any data contained in the NVSIMM.
Use this procedure for OpenBoot PROM upgrades. See Figure 10-17 for the
PROM socket locations. Pin one is at the upper left corner for all the PROMs.
1. To uncover the PROMs, remove the SuperSPARC Module (if any) in
module location B.
2. Use an IC extractor tool to remove the PROMs.
3. Place the PROMs on antistatic foam plastic in an antistatic package for
storage or possible reuse.
