Warning:
The heat sinks on the interface board get very hot. Wait 5 minutes after
powering off your workstation before you touch any internal components.
Touching the heat sinks could result in burns if a cooling-off period is not
observed.
Caution: The components inside your workstation are extremely sensitive to static
electricity. Always wear the wrist strap when you work with parts inside your
workstation. Follow these steps to use the wrist strap:
1. Unroll the first two folds of the strap.
2. Wrap the exposed adhesive side firmly around your wrist, unroll the rest of the
strap, and then peel the liner from the copper foil at the opposite end.
3. Attach the copper foil to an exposed electrical ground, such as a metal part of the
chassis.
After you attach the wrist strap, you can install or remove internal parts of the
workstation. Table 3-2 contains a list of all of the internal components that you can install
or remove and the procedure associated with each one.
Caution: Do not attempt to install or remove components that are not listed in Table 3-2.
Components not listed in Table 3-2 must be installed or removed by a qualified SGI field
engineer.
