Chapter 4 Powering On and Configuring the Sun Fire V100 Server 39
Using the Power (On/Standby) Switch
Caution – The power switch on the back panel of the Sun Fire V100 server is not an
On/Off switch, it is an On/Standby switch. It does not isolate the equipment.
The power (On/Standby) switch is a rocker type, momentary action switch. It
controls only low-voltage signals; no high-voltage circuits pass through it. This
means that the main method of connecting or disconnecting power is by inserting or
removing the power supply cord. The server contains no integral circuit breakers: to
isolate a server, you must break all connections to it. If you do not do this by
removing the power supply cord, you must instead open all external circuit
breakers.
