Handling Static-Sensitive Devices
Attention: Adapters, and disk drives are sensitive to static electricity discharge.
These devices are wrapped in antistatic bags, to prevent this damage.
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 bag until you are ready to install the
device in the system unit.
v With the device still in its antistatic bag, touch it to a metal frame of the system.
v Grasp cards 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 bag, lay it on the
antistatic bag. Before picking it up again, touch the antistatic bag and the metal
frame of the system unit at the same time.
v Handle the devices carefully in order to prevent permanent damage.
Removal and Replacement Procedures
This is the starting point for all removal procedures in the system. Perform the following
steps:
1. Find the location of the part you are replacing in “System Location Codes” on
page 24.
2. Find the field replaceable unit (FRU) you are removing in this section and follow the
procedures.
3. When you have completed the removal procedure, install the FRU by reversing the
removal procedure unless otherwise noted.
4. After exchanging an item, refer to “MAP 0410: Repair Checkout” in the
Diagnostic
Information for Multiple Bus Systems
.
Attention: It is not always necessary to power off the system to exchange a FRU.
You will be directed through a concurrent exchange, if possible.
