After Installing The S4048-On - Dell S4048 Getting Started Manual

Connect the plug to each AC power connector. Make sure that the power cord is secure.
As soon as the cable is connected between the S4048–ON and the power source, the switch is
powered-up; there is no on/off switch.
Fans
The three fan modules and the power supplies are hot-swappable if you install a second (redundant)
power supply.
NOTE: To run the system, the three fan slots must have operating fan units. If you do not install a
module in each slot, the system shuts down in one minute.
NOTE: The S4048–ON supports two airflow direction options. You can only use a single direction in
a chassis; do not mix fan flow types.
• Normal is airflow from the I/O panel to the power supply.
• Reversed is airflow from the power supply to the 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).
After Installing the S4048–ON
After you have securely installed and powered on the S4048-ON, to configure your system, refer to your
