5. Switch off all main line switches for the AC section (ACS) in the power supply
system. (See Section 4.5.3, “Main Line Switch Locations” on page 4-30)

line switches are located on the three-phase ACS.
Note – 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 1-9)
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 1-9)
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.
