Installing Central Processing Units (CPUs)

rp5400 and rp5430 Servers support a maximum of two CPUs.

rp5450 and rp5470 Servers support a maximum of four CPUs.




	CAUTION: Ensure that the following conditions are met before installing a 750 MHz CPU (A6805B): HP-UX 11.0/11.i IPR0109 or later is installed. PDC firmware revision is 42.19 or later. Ensure that the following conditions are met before installing an 875 MHz CPU (6152A): HP-UX 11.i IPR0206 or later is installed. PDC firmware revision is 42.19 or later. Failure to observe these precautions will result in system failure.

The following rules govern the installation of CPUs in rp54xx Servers:

CPUs must be installed in the following slot number order: For
- rp5400 slots 0, 3
- rp5430 slots 0, 2
- rp5450 slots 0, 3, 1, 2
- rp5470 slots 0, 2, 1, 3
For rp5400 and rp5450 single CPU configurations, a processor terminator must be installed in slot 3.
The terminator is not required for rp5430 and rp5470.




	CAUTION: Failure to install the processor terminator, where required, can result in the server failing to pass self-test.

Power down and unplug the rp54xx Server.




	CAUTION: DC voltages are present when the server is connected to AC power. Do not install or service rp54xx internal components while DC voltage is present. Failure to observe this precaution can result in damage to the server.

Make the top of the server accessible for service.
Loosen the captive T-15 screws that hold the top cover in place, then grasp the strap handle, raise the cover slightly, and pull the cover toward the front of the server to free the cover tabs from the slots in the chassis. The air baffle will be exposed.
Loosen the captive T-15 screws on the air baffle. Grasp the two handles on the baffle, and lift the baffle remove it.
CAUTION: Observe all electrostatic discharge (ESD) precautions Do not touch internal components. Failure to observe ESD precautions can cause damage to components.
The following outlines which CPUs and processor support modules are installed for which rp5400 and rp5450 CPU configurations. If installing on an rp5470 proceed to the next step.
Number of CPUs CPU Numbers to be Installed PSM Numbers
to be Installed
One 0 0
Two 0 and 3 0
Three^a 0, 1, and 3 0 and 1
Four^a 0, 1, 2, and 3 0 and 1
The following outlines which CPUs and processor support modules are installed for which rp5470 CPU configurations.
Number of CPUs CPU Numbers to be Installed PSM Numbers

One 0 0
Two 0 and 2 0
Three 0, 1, and 2 0 and 1
Four 0, 1, 2, and 3 0 and 1
Perform CPU Socket Cleaning Procedure detailed in the Removal and Replacement chapter.
Install processor support modules, as required.
Number of Processors Installed Processor Support Modules Required
One (1) CPUs PSM 0
Two (2) CPUs^a PSM 0
Three (3) CPUs PSMs 0 and 1
Four (4) CPUs PSMs 0 and 1
a. If installing a second CPU, on rp5400 or rp5450, remove the processor terminator in slot 3.
Replace the air baffle. Tighten the four captive screws to secure the air baffle in place.
Replace the top cover. Tighten the four captive screws to secure the top cover in place.
For rack configurations, insert the rp54xx Server back into the rack.
For deskside enclosure configurations, replace the deskside enclosure cover.
Plug in and power-up the rp54xx Server.
Use the BCH command in pr to verify that the system recognizes the processors that you have just added.
