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. Z9100-ON ground Dell EMC recommends you ground the Z9100-ON switch. Use your switch in a common bond network (CBN). Connect the grounding cables as described in Z9100-ON Installation. Fans and airflow The Z9100-ON fans support two airflow options: normal and reverse. Normal airflow is from the I/O side to the PSU side. Reverse airflow from the PSU side to the I/O side. Fan combinations Installation of the fans is done as part of the factory install based on SKU type. The Z9100-ON has stock keeping units (SKUs) that support the following configurations: ● AC or DC PSU with fan airflow from the I/O to the PSU-normal airflow ● AC or DC PSU with fan airflow from the PSU to the I/O-reverse airflow 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 Z9100-ON switch. For proper ventilation, position the Z9100-ON in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of clearance around the exhaust vents. Power To connect the switch to the applicable power source, use the appropriate power cable. A 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 powers-up when you connect the power cable between the switch and the power source. CAUTION: Always disconnect the power cable before you service the power supply slots. CAUTION: On an AC switch, use the power supply cable as the main disconnect device. Ensure that the socketoutlet is located and 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 Z9100-ON and components immediately, Dell EMC recommends properly storing the switch and all optional components by following 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.

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.
Z9100–ON ground
Dell EMC recommends you ground the Z9100-ON switch. Use your switch in a common bond network (CBN).
Connect the grounding cables as described in
Z9100-ON Installation
.
Fans and airflow
The Z9100–ON fans support two airflow options: normal and reverse. Normal airflow is from the I/O side to the PSU side.
Reverse airflow from the PSU side to the I/O side.
Fan combinations
Installation of the fans is done as part of the factory install based on SKU type. The Z9100-ON has stock keeping units (SKUs)
that support the following configurations:
●
AC or DC PSU with fan airflow from the I/O to the PSU—normal airflow
●
AC or DC PSU with fan airflow from the PSU to the I/O—reverse airflow
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 Z9100–ON switch.
For proper ventilation, position the Z9100-ON in an equipment rack or cabinet with a minimum of 5 inches (12.7 cm) of
clearance around the exhaust vents.
Power
To connect the switch to the applicable power source, use the appropriate power cable. A 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 powers-up when you connect the power cable between the switch and the power source.
CAUTION:
Always disconnect the power cable before you service the power supply slots.
CAUTION:
On an AC switch, use the power supply cable as the main disconnect device. Ensure that the socket-
outlet is located and 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 Z9100–ON and components immediately, Dell EMC recommends properly storing the switch and all
optional components by following 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.
●
