2. Wear a wrist strap, and always be properly grounded when touching static-
sensitive equipment or parts.
If a wrist strap is not available, touch any unpainted metal surface on the back panel
of any unit to dissipate static electricity. Repeat this procedure several times during
installation.
3. Avoid touching exposed circuitry, and handle components by their edges only.
Caution – Do not power on any units until after you have connected the Sun
StorageTek 5320 NAS Appliance to the network.

To Ground the Rack Installation
1. Include a third-wire safety ground conductor with the rack installation to avoid
the potential for an electrical shock hazard.
2. Use a minimum 14 AWG connected to the earth ground stud on the back of the
server.
3. Connect the safety ground conductor to the chassis stud with a two-hole crimp
terminal with a maximum width of 0.25 inch.
4. Install the nuts on the chassis with a 10 in/lb torque.
The safe ground conductor provides proper grounding only for the Sun StorageTek
5320 NAS Appliance. You must provide additional proper grounding for the rack
and other devices installed in it.
Review specifications in Appendix A to determine isolation and continuous power
requirements.
Main AC Power Disconnect
You are responsible for installing an AC power disconnect for the entire rack unit.
This power source disconnect must be readily accessible, and it must be labeled as
controlling power to the entire rack unit, not only to the servers.
