3 Install a #6 AWG (# 40 Metric Wire Gauge) ground wire from the
cabinet to a ground source (the ground bus in the AC power
service panel).
Note: Do not connect the ground wire to the ground connection in an
existing Option 11C cabinet. The ground wire must be connected to
the ground source.
The connection in the AC power service panel should be performed by
a qualified technician or electrician.
Connect the ground wire to the ground lug located in the bottom of the
cabinet next to the cable connectors.
Route the ground wire through the third groove from the left in the
bottom of the cabinet.
Connect it to the Single Point Ground (SPG) and place a DO NOT
DISCONNECT tag on it.
Note: Refer to the Option 11C "Grounding requirements" on page 39.
4 Put on the wrist strap provided in the bottom of the cabinet and
install the power supply with the circuit breaker at the OFF
position. If this is an AC powered system, plug in the power
supply cord in the commercial power supply receptacle and into
the power supply. Refer "Installing the power supplies" on
page 131.
A grounded wrist strap, provided with the cabinet, must be worn when
handling circuit cards to prevent damage caused by static electricity.
Make sure that the NTAK04 or NTDK78 AC/DC or NTAK05 or
NTDK72 DC power supplies are installed and that their circuit breakers
are set to OFF.
