Plan The Upgrade; Determine Where To Place The Processor Board - HP D7171A - NetServer - LPr Upgrade Manual

2 Plan the Upgrade

Up to four processor boards, each with two 200 MHz/1 MB CPU chips, can be
installed in the HP NetServer LXr Pro8 system. All four processor board slots on
the system board must be filled, even when fewer than four processor boards
(eight CPUs) are installed. Each processor board slot must contain one of two
kinds of boards:
Processor board. The processor board contains two 200 MHz/1MB CPU
chips with two heat pipes and two VRMs (voltage regulator modules).
or
Terminator board. The terminator board uses the same board blank as
the processor board, but it does not contain the CPU chips, heat pipes, or
VRMs. Each terminator board contains just the components necessary to
terminate the bus.
During start up, the control panel of the HP NetServer LXr Pro8 displays how
many CPUs the system detects.

Determine Where to Place the Processor Board

The system comes standard with one processor board and three terminator
boards. Before you can add a processor board, you must remove a terminator
board.
The HP NetServer LXr Pro8 has two CPU buses: A and B. Bus A, containing
slots A1 and A2, is the primary bus. Bus B, containing slots B1 and B2, is the
secondary bus. Table 2-1 shows how processor boards can be added to the HP
NetServer LXr Pro8 to keep the two buses balanced.
