Upgrades Using B4166 and B4168 CPUs B-5
From outside the drawer, there is no easy way to visually distinguish between
the two system drawers; to see the components that differ requires looking
inside the drawer. The best way to determine which drawer is in the system is
to use the show fru command. The 54-class part number is listed on the
QBBx line when the show fru command is issued from either the SCM
monitor or the SRM console.
Configuration Rules
The original (blue) system upgrade is governed by the following rules:
1. Any combination of BA52A-AA, CA, and DA system drawers can be in a
system.
2. The B4125 CPUs run at 731 MHz and require a 9.6 ns system clock. B4125
CPUs are not supported with the 9.0 ns system clock.
3. B4125 CPUs have 4 Mbytes of B-cache. When in a QBB in a BA52A-CA or
DA system drawer, firmware configures these CPUs to be consistent with
the amount of B-cache available.
4. The B4166 and B4168 CPUs can operate at different speeds and use
different amounts of B-cache depending upon the drawer they are in, the
system clock speed, and whether they are configured with the B4125 CPU.
See Table B–1.
5. The B4166 CPU requires that the SRM console and microprocessor
firmware be at V6.0-514 or higher.
6. The B4168 CPU requires that the SRM console and microprocessor
firmware be at V6.3 or higher.
