All CPU chips and Processor Boards in the system must be the same speed/cache combination. Each
Processor Board is marked. For instance, "166/512K" = 166 MHz with 512K cache.
CAUTION
If replacing a processor board with one that has jumpers installed on the Voltage ID Bypass block (jumpers
should never be in positions 1 or 2), check that the system matches one of these configurations:

Operating a CPU chip on an incorrect Processor Board or at a lower or higher than
it was designed, or at incorrect voltage may result in unreliable operation, or may
cause catastrophic or hidden damage to the chip. CPU chips supplied and
warranted by HP for NetServers have an " HP" label. Repairs caused by
unauthorized jumper modification or use of incorrect chip and board combinations
are not covered under the warranty.
