Removing and Replacing Components

Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

Use conductive field service tools.

Use a portable field service kit with a folding static-dissipating work mat.

Replacement Procedures for Hot-Pluggable Components

Removing a hot-pluggable component causes a significant change in the airflow within the enclosure, and the enclosure could overheat if a replacement component is not installed within a relatively short time.

Before removing a component from the enclosure, be sure that a replacement component is immediately available.

If removing a drive, replace it with another drive or a drive blank to maintain the correct airflow in the enclosure.

CAUTION: Be careful when replacing a drive. The drives in the enclosure are fragile.

The following general steps apply to all components. Detailed procedures for removing individual components are given in the appropriate section of this chapter.

1.Remove the replacement component from its static-free container.

2.Check the label on the replacement component to be sure that it is of the correct type.

3.Remove the defective component from the enclosure.

4.Install the replacement component in the enclosure.

5.Observe the status LED of the replacement to confirm that the new component is operating properly.

6.Place the defective component in the static-free container for shipment.

Disk Drive or Drive Blank

Removing a Drive Blank

Squeeze the release latch and hold it in while pulling the blank out of the enclosure.

Removing a Disk Drive

1. Press the release button.
