On/standby button and light
On/standby button and light. Press to turn on the Xserve. Press for 10 seconds to force the Xserve
to shut down if all other shutdown methods fail.
Enclosure lock and lock status light
The lock secures the Xserve cover and drive modules. It can be locked and unlocked with the
enclosure key supplied with the Xserve. An option in the Security pane of System Preferences
lets you inactivate a connected keyboard and mouse when the enclosure lock is engaged. This
option is turned off by default. When the enclosure is locked (the light is on), the Xserve might
not recognize peripheral devices such as a keyboard, mouse, or storage device. Unlock the lock to
use those devices.
