Switch ground
Dell EMC recommends you ground your switch. Use the Z9332F-ON switch in a common bond network (CBN).
Connect the grounding cables as described in
NOTE:
For an AC-powered switch, although the third conductor of the AC power cord provides a ground path, Dell EMC
recommends grounding your switch with a dedicated ground wire.
Fans and airflow
Fan installation is done as part of the factory installation. The Z9332F-ON switch supports AC PSU with fan airflow from the I/O to the
PSU.
The fans ship preinstalled with airflow from the I/O to the PSU. Optionally, you can order and install fans with airflow from the PSU to the
I/O.
•
Fan airflow from the I/O to the PSU—normal
•
Fan airflow from the PSU to the I/O—reverse
CAUTION:
Switches with fan airflow from the PSU to the I/O—reverse airflow—are subject to tighter restrictions for
power consumption on cables and optics that are used for 400 GbE ports. Reverse airflow switches do not support high-
power cables or optics. 400 GbE transceivers and active cables may exceed the supported threshold.
CAUTION:
Review the optics specification sheet to understand which models support airflow from the I/O to the PSU
(normal) and which support airflow from the PSU to I/O (reverse).
NOTE:
Use a single type of airflow fan in your switch. Do not mix reverse and normal airflows in a single switch.
For proper ventilation, position the switch in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance around the
exhaust vents. When you install two Z9332F-ON switches near each other, to permit proper airflow, position the two switches at least 5
inches (12.7 cm) apart. The fan speed varies based on internal temperature monitoring. The Z9332F-ON switch never intentionally turns
off the fans.
For more information, see Fans.
Power
To connect the switch to the applicable power source, use the appropriate power cable. An AC power cable is included with each PSU.
When installing AC switches, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where applicable.
The switch is powered-up when you connect the power cable between the switch and the power source. For more information, see
Power
supplies.
CAUTION:
Always disconnect the power cable before you service the power supply slots. The switch has multiple power
cables. Before servicing, ensure that all power cords are disconnected.
CAUTION:
On an AC switch, use the power supply cord as the main disconnect device. Ensure that the socket-outlet is
located and installed near the equipment and is easily accessible.
NOTE:
PSU airflow must match the airflow direction of the fans. The fans ship preinstalled with airflow from the I/O to
the PSU. Optionally, you can order and install fans with airflow from the PSU to the I/O.
NOTE:
Module power is software that is controlled. You do not see module LEDs when the switch powers up in ONIE.
Storing components
If you do not install your Z9332F-ON switch and components immediately, properly store the switch and all components using these
guidelines:
•
Storage location temperature must remain constant. The storage range is from -40°C 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.
