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

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.
Ground the Z9100–ON (Optional)
Use the Z9100–ON 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.

Fan Combinations

The Z9100-ON has stock keeping units (SKUs) that support the following configurations. Installation of
the fans is done as part of the factory install based on SKU type.
• AC or DC PSU with fan airflow from the I/O to the PSU
• AC or DC PSU with fan airflow from the PSU to the I/O
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 airflows 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. When you install two Z9100-ON systems near
each other, to permit proper airflow, position the two chassis at least 5 inches (12.7 cm) apart. The fan
speed increases when the internal temperature reaches 161.6°F (72°C) and decreases to normal speed
when the temperature falls to 136.4°F (58°C). The Z9100-ON never intentionally turns off the fans.

Power

To connect the chassis to the applicable power source, use the appropriate power cord with the Z9100–
ON. An AC or DC 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 the power cord is connected between the system and the power
source.
CAUTION: Always disconnect the power cable before you service the power supply slots.
CAUTION: Use the power supply cord as the main disconnect device on the AC system. Ensure
that the socket-outlet is located/installed near the equipment and is easily accessible.
