Electrostatic discharge (ESD)
Attention: When you handle field-replaceable units (FRUs) and other computer
parts, take these precautions to avoid static damage:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Always touch the computer parts carefully. Hold the cards by their edges or metal
cover. Never touch any exposed circuits.
v Prevent people who are not correctly grounded from touching computer parts.
v Before you install a new part, touch the static-protective package that contains
the part against an unpainted metal part of the 2104 Model DS4 or host system for at least 2 seconds. This reduces the static electricity in the package and in your body.
v Remove the part from its package and, if possible, install it directly into the 2104
Model DS4 without putting the part down. If you must put the part down, follow these steps:
1. Place the static-protective package that contained the part onto a smooth, level surface.
2. Place the part onto the static-protective package. Do not place the part directly onto any metal surface.

Environmental notices and statements
This section describes the environmental notices and statements.
Fire suppression systems
A fire suppression system is the responsibility of the customer. The customers own insurance underwriter, local fire marshal, or a local building inspector, or both, should be consulted in selecting a fire suppression system that provides the correct level of coverage and protection. IBM designs and manufactures equipment to internal and external standards that require certain environments for reliable operation. Because IBM does not test any equipment for compatibility with fire suppression systems, IBM does not make compatibility claims of any kind nor does IBM provide recommendations on fire suppression systems.
Product recycling
This unit contains recyclable materials. Recycle these materials where processing sites are available and according to local regulations. In some areas, IBM provides a product take-back program that ensures proper handling of the product. Contact your IBM representative for more information.
