cord and thread the tie-wrap through the opening in the relief pedestal.
Pull the end to tighten the tie-wrap.
4. Connect the other end of the AC power cord to the power sequencer in the rack
enclosure, or to an AC outlet.
See the instructions provided with your rack enclosure for information about the
power sequencer. The outlet must connect the system to a 15A circuit in North
America and Japan, and to a 10A circuit in Europe.
Note – You can connect the second power cord to the same AC circuit as the first
supply. However, for increased system redundancy, connect the two power cords to
separate circuits.
