Fans; Components; Installing A Fan Module - Dell Z9000 Manual

Fans

The Z9000 comes from the factory with one power supply unit (PSU)and two fan modules installed in the
system.
If two or more fans are installed and running, the fan modules are hot-swappable.
The Z9000 supports two airflow direction options. Do not mix airflow directions; you can use only a
single airflow direction in a chassis. If the airflow directions are mismatched, the Z9000 powers down in
one minute.
• Normal — airflow is from the I/O panel to the PSU. The grab-handle is labeled Exhaust.
• Reversed — airflow is from the PSU to the I/O panel. The grab-handle is labeled Intake.
Environmental factors can decrease the amount of time required between fan replacements. Check the
environmental factors regularly. An increase in temperature and/or particulate matter in the air might
affect performance (for example, new equipment installation).
CAUTION: If the wrong fan air flow is ordered or if the wrong fans are received with your Z9000,
the entire Z9000 must be replaced. Normal fans cannot be swapped with reverse air flow fans;
the unit must be replaced.
CAUTION: Check the fans at six-month intervals and replace them as necessary. Regularly
monitor the speeds of the cooling fans in order to accurately determine replacement intervals.

Components

The following are the Z9000 fan components.
• Z9000 Fan module
• Z9000 Fan module - Reverse flow

Installing a Fan Module

The fan modules in the Z9000 are field replaceable.
Module slot 0 is on the left side of the chassis; module slot 1 is on the right side of the chassis.
CAUTION: DO NOT mix airflow directions. Both fans must use the same airflow direction (reverse
or normal). If the airflows are mismatched, an error message appears and the system shuts down.
