Ac Power; Fans; After Installing The S4810-On - Dell Networking S4810 Getting Started Manual

AC Power

CAUTION: Ensure that the PSU is installed correctly. The AC power connector must be on the left
side of the PSU and the status LED at the top of the PSU.
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 S4810–ON and the power source, the switch is powered-
up; there is no on/off switch.

Fans

Both the fan module and the integrated fan-power supply are hot-swappable if a second (redundant)
power supply is installed and running.
NOTE: To run the system, both slots must have operating fan units. If you do not install a module in
each slot (either as part of the PSU or as an independent fan module), the system shuts down in one
minute.
NOTE: The S4810–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 S4810–ON
After you have securely installed and powered on the S4810-ON, to configure your system, refer to your
ONIE-compatible third-party operating system documentation.
