10 Sun Fire V890 Server Owner’s Guide • September 2004
The three power supplies are accessible from the system rear panel. Each power
supply has three LED indicators for displaying power status and fault conditions.
See “About Power Supply LEDs” on page 145 for additional details.
A grounding screw is located just above the center power supply. When installing a
Sun Fire V890 server into a rack, or connecting the server to an external storage
array, be sure to connect an appropriate grounding strap between the server’s
grounding screw and the grounding screw on the rack enclosure or external storage
array. A grounding strap prevents ground loops between systems and peripherals
and helps guard against possible data loss.
