How to Reset the Server Using the Reset Switch (SW2)

The reset switch (SW2) is located on the rear exterior panel of the server.

Before You Begin

You need a stylus or some other thin pointed nonconducting object to press the Reset switch.


Caution

Caution - Data loss can occur if the system is in an operational or functioning state and the reset button is pressed. The Reset switch performs an immediate reset of the server and does not provide a graceful shutdown of the OS.


  1. Access the rear panel of the server and locate the Reset switch (SW2) (see Sun Fire X4640 Server Back Panel Features and Components).
  2. To reset the server, use a stylus or nonconducting thin pointed object to press the recessed reset switch.

    The system immediately resets and reboots.
