Rack Mounting; Z9100-On Ground; Fans And Airflow; Fan Combinations - Dell Z9100-ON Installation Manual

The cabinet must meet minimum size requirements. Airflow must be in accordance with the Electronic Industries Alliance (EIA) standard.
Ensure that there is a minimum of 5 inches (12.7 cm) between the intake and exhaust vents and the cabinet wall.

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 recommends you ground the Z9100-ON system. Use your system in a common bond network (CBN).
Connect the grounding cables as described in

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 system. Do not mix reverse and
normal air flows in a single Z9100–ON chassis.
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 chassis to the applicable power source, use the appropriate power cord. A power cord is included with the system.
When installing AC or DC systems, follow the requirements of the National Electrical Code, ANSI/NFPA 70, where applicable.
The system is powered-up when you connect the power cord between the system and the power source.
CAUTION: Always disconnect the power cable before you service the power supply slots.
CAUTION: On an AC system, 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.

Storing components

If you do not install your Z9100–ON and components immediately, Dell recommends properly storing the system and all optional
components by following these guidelines.
• Storage location temperature must remain constant. The storage range is from -40° to 158°F (-40°C to 70°C).
• Store on a dry surface or floor, away from direct sunlight, heat, and air conditioning ducts.
• Store in a dust-free environment.
