Rack mounting
When you prepare your equipment rack, ensure that the rack is grounded. Ground the equipment rack to the same ground point
the power service in your area uses. The ground path must be permanent.
Switch ground
Dell Technologies recommends grounding your switch. Use the Z9432F-ON switch in a CBN.

Fans and airflow
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type. The Z9432F-ON switch has SKUs
that support the following configurations:
●
AC PSU with fan airflow from the I/O to the PSU—normal
●
AC PSU with fan airflow from the PSU to the I/O—reverse
●
DC fan unit with airflow from the I/O to the PSU—normal
●
DC fan unit with fan airflow from the PSU to the I/O—reverse
Be sure to order the fans suitable to support your site ventilation. Use a single type of fan airflow in your switch.
NOTE:
Fan and PSU airflow directions must match. Do not mix normal and reverse airflows in a single switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 12.7 cm (5 inches) of clearance
around the exhaust vents. The fan speed varies based on internal temperature monitoring. The switch never intentionally turns
off the fans.
Power
Connect the switch to the applicable power source using the appropriate power cable. An AC power cable is included with the
switch.
When installing AC or DC switches, follow the code requirements appropriate for your country/region. For example, in the U.S.,
follow
National Electrical Code ANSI/NFPA 70
and in Europe follow
IEC60364
.
The switch powers-up when the power cable connects the switch to the power source.
CAUTION:
Always disconnect the power cables before you service the power supply slots. The switch has
multiple power cables. Before servicing, disconnect all power cables.
CAUTION:
On the AC switch, use the power supply cable as the main disconnect device. Ensure that the socket
outlet is located or installed near the equipment and is accessible.
NOTE:
Module power software controlled. You do not see module LEDs when the switch powers up in ONIE.
Storing components
If you do not install your Z9432F-ON switch and components immediately, properly store the switch and all optional components
following these guidelines:
●
Storage location temperature must remain constant. The storage range is from -40° to 70°C (-40° to 158°F).
●
Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
●
Store in a dust-free environment.
