Handling static-sensitive devices

Working with hot-swap drives

© Copyright IBM Corp. 2000
This chapter provides instructions for installing or replacing customer replaceable
units (CRUs), such as hot-swap drives, ESM boards, the bridge card, the switch card,
and power supplies.
Static electricity, though harmless to you, can seriously damage expansion unit
components or options.
Note: When you are adding an internal option, do not open the static-protective
package containing the option until you are instructed to do so.
When you handle options and other expansion unit components, take these
precautions to avoid damage from static electricity:
• Limit your movement. Movement can cause static electricity to build up around
you.
• Always handle components carefully. Never touch any exposed circuitry.
• Prevent others from touching components.
• When you are installing a new option, touch the static-protective package
containing the option to an unpainted metal surface on the expansion unit for at
least two seconds. (This reduces static electricity from the package and from
your body.)
• When possible, remove the option and install it directly into the expansion unit
without setting the option down. When this is not possible, place the static-
protective package that the option comes in on a smooth, level surface and place
the option on it.
• Do not place the option on the expansion unit cover or on any metal surface.
• When possible, wear an electro-static discharge (ESD) protective ground strap.
Before you begin
• Read the safety and handling guidelines provided in "Safety" on page v and
"Handling static-sensitive devices."
• Ensure that your current system configuration is working properly.
• Back up all important data before you make changes to storage devices, such
as hard disk drives.
This section explains how you can increase the expansion unit capacity by adding
more drives or replacing existing drives with larger capacity drives.
