Netra 240 Server Tip Hazard
Controlling Server Power
You must open the bezel to access the On/Standby button and the rotary switch. The
On/Standby button controls only the
power state of the server. It does not isolate the
server from its electrical power source. Turning the power off does not disable the
ALOM. For information on controlling server power using software, refer to the
Sun
Advanced Lights Out Manager Software User’s Guide for the Netra 240 Server (817-3174).
The On/Standby button is a momentary switch and has two operation modes:
■
Press and immediately release.
■
Press and hold down for more than 4 seconds.
The On/Standby button does not power off the server. It toggles the server between
on and standby (
FIGURE 2-2
). The results of these actions are summarized in
TABLE 2-1
