Handling Static Sensitive Devices
Electronic components on printed circuit boards can be damaged by static
electricity. Always wear a grounding strap and use an antistatic mat when
handling boards or components.
Reference Documentation
Standard Configurations and Standard Options supported by Sun Microsystems
are documented in the End User Price List, Reseller Price List, Hardware
Configuration Guides, Product Brochures, and Hardware Installation Manuals.

Dip Switches
Rocker and Slide type DIP Switches are used in Sun products. Turn on a
Rocker-type switch by pressing down the end of the switch furthest from the
OPEN lettering on the switch. Turn on a Slide-type switch by sliding the
switch in the direction of the arrow on the switch. Switches 1 and 2 are
shown in the ON position in these illustrations.
Jumpers
Jumpers are used to connect two pins of a Terminal Strip. Two sizes of
jumpers are used: 0.100 inch and 2.0 millimeter.
To program the EEPROM or NVRAM using the Sun PROM
Monitor, enter q followed by the hexadecimal address in
the EEPROM or NVRAM to open and display the contents.
Change the contents by typing in the new value followed by
a carriage return. To exit, type a space and <CR>, or a
"." and <CR>.
