Securing the Server
1. Power on the server.
This step includes reconnecting power cables, verifying the state of the LEDs, and
turning the keyswitch to the Locked position. See
Server Off Using Software” on page 4-12
.
Note –
If the Oracle Solaris automatic booting is set, use the sendbreak -d
domain_id command after the display console banner is displayed but before the
system starts booting the operating system to get the ok prompt.
2. Confirm the hardware.
This step includes running programs to be certain all components are mounted
again and then booting the operating system.
Refer to
Section 4.3.2, “Verifying Hardware Operation” on page 4-9
for more
information.

The DC-DC converters are cold replacement components. This means the entire
server must be powered off and the power cords disconnected to replace a DC-DC
converter on the I/O unit.

Connector, and the DC-DC Converter Riser.
