Switch ground
Dell EMC recommends grounding your switch. Use the Z9264F-ON switch in a CBN.
For more information, see
Fans and airflow
Fan installation is done as part of the factory install based on stock keeping unit (SKU) type.
The Z9264F-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's ventilation. 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. 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 requirements of the National Electrical Code
ANSI/NFPA 70, where applicable.
The switch is powered-up when the power cable is connected between the switch and the
power source.
CAUTION:
Always disconnect the power cable before you service the power supply
slots. The switch has multiple power cords. Before servicing, ensure all power cords
are disconnected.
