Attention: Components in the frame are susceptible to damage from static discharge. Always use an ESD wristband when working inside frame covers. (See ªPersonal ESD requirementsº on page 3-1 for more details.) Do not touch the pins or circuitry on these components.

This chapter describes the removal and replacement of RS/6000 SP product-specific Field Replaceable Unit (FRU) components.

Handling static-sensitive devices

Attention: Adapters, planars, disk drives, supervisor cards and memory cards are sensitive to static electricity discharge. These devices are wrapped in antistatic bags or containers to prevent this damage.

Perform the following procedures to prevent damage to these devices:

1.Do not remove the device from the antistatic bag or container until you are ready to install the device in the system unit.

2.You must wear an ESD wristband while installing or removing any static-sensitive devices.

3.With the device still in its antistatic bag, touch it to a metal frame of the system.

4.Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching the solder joints and pins.

5.Handle the devices carefully in order to prevent permanent damage.
