To prepare the system for maintenance, you can follow the guidelines in "Powering On and Off"
in Chapter 1 and power down the affected blade enclosure pair. The section also has information
on powering-up the enclosure after you have completed the maintenance/upgrade required.
If your system does not boot correctly, see Chapter 6 for troubleshooting procedures.
Caution: The components inside the system are extremely sensitive to static electricity. Always
wear a wrist strap when you work with parts inside your system.
To use the wrist strap, follow these steps:
1. Unroll the first two folds of the band.
2. Wrap the exposed adhesive side firmly around your wrist, unroll the rest of the band, 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.
Caution: Do not attempt to install or remove components that are not listed in Table 7-1.
Components not listed must be installed or removed by a qualified SGI field engineer.
Table 7-1 lists the customer-replaceable components and the page on which you can find the
instructions for installing or removing the component.
