Chassis Physical Design - Dell Force10 S4810P Quick Start Manual

chassis is powered-up; there is no on/off switch.
Fans
The S4810 comes from the factory with 1 power supply and 2 fan modules
installed in the chassis. Both the fan module and the integrated fan-power
supply are hot-swappable if a second (redundant) power supply is installed and
running.
NOTE: Both slots must have operating fan units to run the system. If a module is
not installed in each slot (either as part of the PSU or as an independent fan
module), the system will shut down in 1 minute.
The S4810 supports two airflow direction options. Only a single direction can
be used in a chassis; do not mix fan flow types in a chassis. The system will
shutdown in 1 minute, if the airflow directions are mismatched.
• Normal is airflow from I/O panel to power supply.
• Reversed is airflow from power supply to I/O panel.
There are environmental factors that could decrease the amount of time required
between fan replacements. Check these environmental factors regularly. Any
unusual environmental circumstance at the site that causes an increase in
temperature and/or particulate matter in the air might affect performance (for
example, new equipment installation).
