Installing the S4810 System
33
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..
In addition to the integrated fan/power supply modules, fan modules can be ordered separately and
additional modules can be inserted in the chassis.
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).

Fans
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.
CAUTION:
Fans should be checked at six-month intervals and replaced as necessary. Regularly monitor
the speeds of the cooling fans in order to accurately determine replacement intervals.
