HP Netserver Service Handbook, Volume 3 - High-End

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 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.

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:

Total number of CPU

chips in system

Processor Board

Slot #1

Processor Board

Slot #2

1 CPU 1 Terminator Board *

2 CPU 1 and CPU 2 Terminator Board *

3 CPU 1 and CPU 2 CPU 1

4 CPU 1 and CPU 2 CPU 1 and CPU 2

* Termination Board D4262-60002 or D4262-63002

Processor Board in Slot #1 must have two chips before adding a board in Slot #2. All board slots must be

filled. A Processor Board without chips cannot be used as a terminator.

NOTE If two processor boards are installed in the system, both must be the same speed, as

indicated by the board part number labels.
