DOCTECA: Instalar CPU en Rp4440

Introduction

Often, you see rp4440's with one CPU. They have 4 sockets, so might as well get have more than one CPU and use the extra sockets. You need to get the exact same CPU. You can see the details of your installed CPU at the BCH menu (at boot time, interrupt the boot).

Get Prepared

Reboot the machine (or power it on). Get console to it, so you can see the boot sequence. When the BCH menu displays, hit esc to interrupt the boot. Type

You need:

Sane people use a anti-static wrist strap when they mess with thousand dollar CPUs. Maybe they know something. Get a wrist strap and ground yourself.
The Fscking Manual (TFM). Yes, read the manual. It has a pretty good step by step.
A long 2.5mm hex allen wrench to lock/unlock the CPU socket. I got mine on eBay for a couple of bucks. The official $75 HP tool is just a 2.5mm allen wrench.
A Torx screwdriver for the CPU and power supply fasteners (IIRC it's a T15). I bought mine on eBay for a couple of dollars.
The EXACT same CPU. Same speed, same cache size. Of course, buy one for your exact model number of server (rp4440 in this case). It seems like HP packaged the same actual Itanium chips into 50 different CPU modules, every server has different ones. BE VERY SURE. CPUs are expensive. (Of course, shop around and get a good price. If you can't return it, you can sell it on eBay).

Follow the Procedure in the Manual

Follow the steps in the manual. This is from page 86, "Installing Processors". I'll only mention exceptions here. Remember, go very slowly and gently. Nothing is forced, if you're doing it right, everything is smooth and easy. Don't bend any pins. If you encounter resistance, then stop, read the manual again, and think it through. Remove processor extender board by:

Step 1. You don't need to slide server out to add a CPU or RAM. That's why these are accessible from the front.
Step 2. Remove bezel.
Step 3. Remove front cover.
Step 4. Press latches on extraction levers on processor extender board.
Step 5. Pull out extraction levers on processor extender board.
Step 6. Remove processor extender board.

Install a processor on the extender board by:

Step 1. Decide which socket to use. Use the next numbered socket available.
Step 2. Unlock socket. Practice with the tool and go through a couple lock-unlock cycles. Become familiar with what "unlocked" and "locked" feels like. When you do this for real in a moment, the CPU obstructs your view of the handy little locked/unlocked icons. I put a little "flag" on my tool so it's realy easy to see what 180 degree rotation looks like. See pictures below.
Step 3. Unpack CPU. The "sequencer frame" (mine is blue) comes off the processor/power supply assembly. Separate the sequencer frame from the processor module. See pictures below.
Step 4. Inspect processor pins. Make sure none are bent. Remember what they look like now. Later you might need to look at them again to make sure you haven't bent any. They are very easy to bend.
Step 5. GENTLY, gently lower processor onto socket. Apply no pressure, it should easily, easily come to rest, no pressure needed. The hard thing is routing the silly power supply cable. RTFM. They have pictures on proper cable routing. You almost need three hands. You have to place the processor in place, hold the cable in place, make sure not to dislodge the cable connectors on the CPU module and make it all work without bending any pins. I bent pins the first time. Gently remove the processor, and bend the pins back into place.
Step 6. Lock the CPU into place with the allen wrench.
Step 7. Plug the power supply cable into the motherboard.
Step 8. Place the sequencer frame over the processor.
Step 9. Hand tighten the two knurled thumbscrews on the sequencer frame.
Step 10. In a X pattern (RTFM), tighten the non-knurled screws with the allen wrench.
Step 11. Tighten the knurled screws with the allen wrench.
Step 12. Verify operation in BCH with the INfo PRocessor 'in pr' command.
