vEnvironmental notices and statements
Safety notices and their translations
Safety notices are printed in English throughout this document.
ADanger notice warns you of conditions or procedures that can result in death or
severe personal injury.
ACaution warns you of conditions or procedures that can cause personal injury that
is neither lethal nor extremely hazardous.
An Attention notice warns you of conditions or procedures that can cause damage
to machines, equipment, programs, or data.
For translations of the danger and caution notices, see Expandable Storage Plus
2104 Model DS4 and Model TS4 Translated Safety Notices, SC26-7558. The
notices are listed in numeric order based on their IDs, which are displayed in
parentheses, at the end of each notice. See the following examples of danger and
caution notices for the location of the ID number.
DANGER
An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the devices that attach to that
system. It is the customer’s responsibility to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock. During an
electrical storm, do not disconnect cables for display stations, printers,
telephones, or station protectors for communication lines. (4)
CAUTION:
Do not insert hands or tools into the empty space that contained the
fan-and-power-supply assembly. (11)

Electrostatic discharge (ESD)
Attention: When you handle field-replaceable units (FRUs) and other computer
parts, take these precautions to avoid static damage:
vLimit your movement. Movement can cause static electricity to build up around
you.
vAlways touch the computer parts carefully. Hold the cards by their edges or metal
cover. Never touch any exposed circuits.
vPrevent people who are not correctly grounded from touching computer parts.
vBefore you install a new part, touch the static-protective package that contains
the part against an unpainted metal part of the 2104 Model TS4 or host system
for at least 2 seconds. This reduces the static electricity in the package and in
your body.
vRemove the part from its package and, if possible, install it directly into the 2104
Model TS4 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.
Safety inspection procedures
The safety inspection procedures describe how to inspect the 2104 Model TS4.
CAUTION:
The 2104 Model TS4 is designed to be installed by the customer and are
certified as customer setup. Make sure that the system or rack into which the
2104 Model TS4 will be installed is also designed and certified for customer
setup. If the 2104 Model TS4 are not, then they must be installed by a CE. (22)
