Chapter 9. Removal and Replacement Procedures
This chapter provides removal and replacement instructions for FRUs that are associated with the 7038
Model 6M2 processor subsystem. For removal and replacement of FRUs associated with the an I/O
subsystem, see the pSeries 7311 Model D10 and Model D20 Service Guide, order number, SA38-0627.
Before performing any of the removal or replacement procedures in this chapter, read the following
notices.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on metal parts
of the system or the devices that attach to the system. It is the responsibility of the customer
to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers, telephones,
or station protectors for communications lines.
D06
CAUTION:
This product is equipped with a three-wire power cable and plug for the user's safety. Use this
power cable with a properly grounded electrical outlet to avoid electrical shock.
C01
CAUTION:
This unit has more than one power supply cord. To reduce the risk of electrical shock,
disconnect two power supply cords before servicing.

Handling Static-Sensitive Devices
Attention:
Disk drives, tape drives, and CD-ROM drives are sensitive to static electricity discharge.
These devices are shipped in antistatic containers to prevent damage caused by electrostatic discharge.
Take the following precautions:
v If you have an antistatic wrist strap available, use it while handling the device.
v Do not remove the device from the antistatic container until you are ready to install the device in the
system unit.
v With the device still in its antistatic container, touch it to a metal frame of the system.
v Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching the solder joints or
pins.
v If you need to lay the device down while it is out of the antistatic container, lay it on the antistatic
container. Before picking it up again, touch the antistatic container and the metal frame of the system
unit at the same time.
v To prevent permanent damage, handle the devices carefully.
When connecting interface cables to electronic cards, for example, riser cards, or adapters, press the
exposed cable connector firmly against the ESD dissipation pad before plugging the cable into the adapter
connector. The ESD dissipation pad is located on the lower right side of the back of the rack just above
the hinge. If the rack you are servicing has the 4 inch rack extension look for the dissipation pad to be on
