Z9432F-ON switch installation
To install the Z9432F-ON switch, complete the installation procedures in the order given.
Before unpacking the switch, inspect the container and immediately report any evidence of damage.
CAUTION:
ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel
ground strap when handling the Z9432F-ON switch and components. As with all electrical devices of this type,
take all the necessary safety precautions to prevent injury when installing this switch.
Always handle the switch and components with care. Avoid dropping the switch or its field replaceable units (FRUs).

Attach a ground cable
To attach a ground cable to the switch, use the included M4 screws.
CAUTION:
Grounding conductors must be made of copper. Copper conductors offer better conductivity and
durability. Do not use aluminum conductors.
CAUTION:
For an AC-powered switch, although the third conductor of the AC power cable provides a ground
path, Dell Technologies recommends grounding your switch with a dedicated ground wire. Using a dedicated
ground wire reduces equipment communication interference, offers ESD protection, and prevents possible
equipment damage.
CAUTION:
For a DC-powered switch, the only way to safely ground your switch is to attach a dedicated ground
wire. The ground lug ships inside the DC PSU shipping box. The two ground lug screws ship attached to the
switch. Before you install the DC switch in a rack, attach the ground lug to the switch using the included
screws. Next attach the DC ground wire to the ground lug.
The ground cable is not included.
To properly ground your switch:
●
Coat the one-hole lug with an antioxidant compound before crimping. Also, bring any unplated mating surfaces to a shiny
finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from contamination.
●
Ensure that the conductor screw is not smaller than the conductors supplying power. Secure all screws and ground-wire
connections.
1. Cut your ground cable (not included) to the wanted length. The cable length must facilitate proper operation of the fault
interrupt circuits. Use the shortest cable route required.
NOTE:
The ground cable must be 10 AWG minimum. The nominal thread diameter screw type is 4.0 mm (0.157 in).
2. Crimp the ground cable to the lug. Attach the lug to the switch by using the two included M4 screws. Torque the screw to
±5 - 6 in-lbs.
3. Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.
The rack installation ears are not a suitable grounding point.
