actions:
■ Press and hold down the POWER switch on the operator panel for at least four

power-off processing is executed.
4. Confirm that shutdown processing is completed by confirming that the READY
LED (green) on the HDD is off.
5. Switch off all main line switches for the AC section (ACS) in the power supply
system.
For details, see Section 4.5.3, “Main Line Switch Locations” on page 4-27.
Note – If the optional three-phase 200 VAC input power supply unit is installed, the
main line switches are located on the three-phase ACS.
Caution – If the dual power feed option is installed, switch off the main line
switches for both power supply units.
Caution – After stopping all the domains, be sure to switch off the main line
switches in the power supply system to completely shut off the supply of power.
6. Connect the clip of the antistatic wrist strap and of the antistatic mat to the
server grounding port. See Section 1.4, “Antistatic Precautions” on page 1-6.
7. Ensure that the metallic underside of the wrist strap is in direct contact with
your skin. The wrist strap should be snug around the wrist so that it does not
rotate. See Section 1.4, “Antistatic Precautions” on page 1-6.
Caution – Before handling FRUs, be sure to connect the clip of the antistatic wrist
strap and of the antistatic mat to the server grounding port, and attach the band of
the wrist strap to one of your wrists. Place the FRUs on the grounded antistatic mat.
Failure to take these antistatic measures might result in serious damage.
