6.2.2 System-Code SIMM Replacement
Following is the procedure for upgrading the system-code Flash or PROM
SIMMs:
1.
Attach an ESD-preventive wrist strap.
2.
Turn the CRBRIM-W/T so that the system board is in the position shown in
Figure 6-3, with the system-code SIMM toward you.
3.
Locate the system-code SIMMs on the CRBRIM-W/T. (See Figure 6-1.)
4.
Remove the existing system-code SIMM by pulling outward on the
connectors to unlatch them. The connector holds the SIMM tightly, so be
careful not to break the holders on the SIMM connector.
The Flash SIMM for the CRBRIM-W/T is available only from
Cabletron. Contact Cabletron Systems for more information.
NOTE
To prevent damage, do not push on the center of the SIMMs.
Handle each SIMM with care.
