Setup Guide

Switch ground
Dell EMC recommends grounding your switch. Use the Z9264F-ON switch in a CBN.
For more information, see Ground lug assembly.
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.
CAUTION: On the AC switch, use the power supply cable as the main disconnect device. Ensure that the socket-outlet is
located/installed near the equipment and is easily accessible.
NOTE: Module power is software controlled. You do not see module LEDs when the switch powers up in ONIE.
Storing components
If you do not install your Z9264F-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.
NOTE:
ESD damage can occur when components are mishandled. Always wear an ESD-preventive wrist or heel ground
strap when handling the switch and its accessories. After you remove the original packaging, place the Z9264F-ON
switch and its components on an anti-static surface.
