Frequently Asked Questions
What hardware is supported by the S4048-ON chassis?
It supports forty eight SFP+ ports (10 Gbps), six QSFP+ ports (40 Gbps), two AC/DC PSUs, and three fan subsystems.
How do I upgrade or downgrade the Networking OS?
Upgrading requires uninstalling the old Open Automation package first. Downgrading also necessitates uninstalling the newest OA package.
What does the system do if the fan trays are faulty?
The system will shut down after one minute if all three fan trays are empty or found to be faulty.
Can I use non-Dell qualified optics in this switch?
Yes, but Dell EMC Networking does not guarantee their performance because the S4048-ON does not support non-Dell qualified 40G transceivers.
