13.3 Hot Replacement
The procedure for hot replacement is as follows.
1. Unlock and open a door of the server. (See Chapter 5)
Caution – Before touching a FRU or dummy (filler) unit, see Section 1.4, “Antistatic
Precautions” on page 1-9 and be sure to wear the antistatic wrist strap. Failure to do so might
result in serious damage to operating domains.
2. Turn off power to the relevant domain.
From a console that is connected to XSCF, log in to XSCF, and execute the
poweroff -d command.
The shutdown processing is executed for the relevant domain, and then the power-off
processing is executed.
3. Confirm that the power-off processing is completed by confirming that the POWER
LED (green) on the PCI card is off.
4. 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 1-9)
5. 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 1-9)
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.
