17382   Configuring 336-MHz CPU into a Sun Enterprise Ultra[TM] E10000   17 Jun 2002

Status Issued

Description
After upgrading an Enterprise 10000 System from 250-MHz processor modules   
to 336-MHz CPU modules (Part# 501-4363), upon reboot, the 336-MHz CPU 
modules are NOT auto-configured into the system.  You will need to manually
change the clock multiplier from 3:2 to 2:1, for configuring the E10000
sytem with the 336-MHz CPU modules.

After upgrading the E10000 system with 336-MHz CPU modules, from the SSP, run
the SSP command:

                sys_clock -p two-to-one -s

                The sys_clock command must be run before the system
                is brought up (Before POST is run).
               
To check the multiplier value, type:

		sys_clock 
COMMENTS:

To prevent a system crash, do NOT perform the sys_clock command on a running 
system.
