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.
8. Using a Phillips screwdriver, loosen the knob screw of the fixing bracket of the
PSU to release the bracket, and open it 180 degrees. (See
FIGURE 9-8 or
FIGURE 9-9)
9. While pushing the lock lever (green) of the PSU to be replaced, raise the handle
to about 45 degrees, and pull out the PSU slowly from the slot.
10. Place the removed PSU on an antistatic mat.
11. Mount the replacement PSU by following the removal instructions in Step 8
and Step 9 in reverse order. Align the PSU with the slot guides, insert it
carefully, and secure it firmly.
Caution – Do not forcibly push the PSU when inserting it, even if it is not moving
smoothly. If the PSU is forcibly inserted despite the presence of any obstruction in a
slot or any problem with a connector pin, serious damage may result.
12. Switch on all main line switches for the AC section (ACS) in the power supply
system.
13. Confirm that the XSCF STANDBY LED (green) on the operator panel remains
lit. If it is blinking, wait until it remains lit.
14. Start (turn on power) all domains together. Take either of the following two
actions:
■ Press and hold down (for less than four seconds) the POWER switch on the
operator panel.
■ From a console that is connected to the XSCF, execute the poweron -a
command of XSCF.
The power to all the domains is turned on, and then the power-on self test (POST)
is executed. When ok prompt displayed on the console of relevant domain, POST
is completed.
For details of the power-on operation, see Section 4.4.2, “Powering the Server On”
