5.Connect the AC power cord.

6.Detach the wrist strap.

7.Replace the side access cover.

See Section 7.3, “Replacing the Side Access Cover” on page 7-4.

8.Reset the #power-cyclesNVRAM variable to zero as follows:

a.Power on the system unit.

See Section 6.1, “Powering On the System Unit” on page 6-2.

b.Press the keyboard Stop and A keys after the system banner appears on the monitor.

c.At the ok prompt, type:

ok setenv #power-cycles 0

d.Verify the #power-cyclesNVRAM variable increments each time the system unit is power cycled.

Note –The Solaris operating environment Power Management software uses the #power-cyclesNVRAM variable to control the frequency of automatic system shutdown if automatic shutdown is enabled.
