HP Server Processor Upgrade Installation Kit
The following includes steps to replace a processor or install an additional processor in the HP Server tc4100. The basic
server ships with one processor in the primary processor socket.
The HP Server tc4100 supports two processors that must operate at the same clock speed, cache size, and FSB speed.
Both processor sockets are located on the system board.
Where to Obtain Installation Instructions
Complete processor installation and removal instructions can be found in both of the following sources:
•The HP Server Operations and Maintenance Guide, on the HP Server Documentation CD-ROM shipped with your
HP Server, includes an installation chapter.
•The HP Server Operations and Maintenance Guide for your HP Server can be viewed and printed from the HP web
site:

Tools Required
An antistatic service kit (3M™ 8501/8502/8503 or equivalent). This kit includes a static-dissipating work surface, a
chassis clip lead, and a wrist strap.
Removing the Processor or Terminator
The installation procedure is the same for the rack-mounted models as for the pedestal models of the server once you
gain access to the system board.
1. Unpack the processor shipping box and check the contents against its packing list.
2. Verify the processor speed and FSB setting, before installing the second processor module.
3. Gracefully shut down the network operating system according to directions in your NOS documentation.
4. Power off your HP Server according to directions in the HP Server Operations and Maintenance Guide.
5. Disconnect the power cords and any connected phone lines.
CAUTION Do not open the new processor's protective bag or remove it from the bag until you are
ready to install it.
Before you remove a processor from the antistatic container, touch a grounded, unpainted
metal surface on the HP Server tc4100 to discharge static electricity.
Use an antistatic wrist strap and a grounding mat. Wear a wrist-strap and use a static-
dissipating work surface connected to the chassis when handling components. Ensure that
the metal of the wrist strap contacts your skin.
WARNING Power supplies will continue to provide standby current to the server until the power
cords are disconnected.

6. To gain access to the system board, follow the instructions for removing the cover and air scoop in the HP Server
Operations and Maintenance Guide.
7. If you are removing the terminator to install a second processor, remove the terminator from the secondary processor
socket by lifting up the lever and pulling the terminator upwards (Figure 1). Save the terminator in an antistatic
protective bag for future needs. Skip to “Installing the Processor” later in this document.
8. If you are replacing a processor:
a. Release the heat sink from the installed processor. Press down on a heat sink clip and rotate the clip to free it from
the tabs on the processor socket. Repeat this step for the second heat sink clip.
b. Remove the heat sink from the processor. Save the heat sink for future needs.
c. Remove the processor from the processor socket by lifting up the lever and pulling the processor upwards
(Figure 1). Save the processor in an antistatic protective bag for future needs.

NOTE The system board is shown removed from the HP Server tc4100 for simplicity in the
following figures, but it is not necessary to remove the system board to install the new
processor module.

Installing the Processor
1. Remove the processor module from the sealed bag.
Figure 2. Installing the Processor
2. Align the processor module over the processor socket by matching the corner of the processor that has fewer pins
with the corner of the socket that has fewer pins.
3. Gently push down on the processor module until it seats.
4. Lower the lever to completely seat the processor module firmly in the socket.
NOTE Thermal grease has been applied to the heat sink at the factory. No additional
thermal grease needs to be applied to the heat sink or the processor during initial
installation.
The tube of thermal grease in the kit should be saved and MUST be used in the
following instances:
•If problems are experienced during installation that result in some of the grease
getting scraped off.
•Every time after initial installation that the heat sinks are removed and
reinstalled.
The following steps must be followed when re-applying thermal grease to ensure
proper thermal conductivity which will prevent damage to the processor that is
caused by overheating:
1. Clean off all of the existing thermal grease from the processor and the heat sink
using a cloth and isopropyl (rubbing) alcohol.
2. Set the server unit in a position so that the processor top surface is parallel to the
ground level.
3. Apply the entire tube of thermal grease to the center area of the processor.

5. To install the heat sink:
a. Center the heat sink properly over the additional processor.
b. Locate the bottom notched edge of the heat sink and, when placing the heat sink over the processor, be sure that
the notched edge faces the front panel of the HP Server.
Figure 3. Installing the Heat Sink
3. Fasten the rear heat sink clip by matching the holes of the clips with the tabs of the socket.
4. Fasten the front heat sink clip in the same fashion.
5. Re-install the air scoop, cover, and bezel onto the HP Server according to directions in the HP Server Operations
and Maintenance Guide.
Return power to the server and restore normal operation.
NOTE HP recommends installing the heat sink supplied with the processor upgrade kit in
the following steps.
CAUTION Ensure you have made good contact with the processor to avoid thermal overheating. If
you have not made good contact with the processor, it will overheat within 20 seconds of
power on and will shut down.
NOTE When installing a second processor, the processor speed is set automatically. No manual
setting of switches is necessary.
