Frequently Asked Questions

What hardware components are supported by the S4048-ON chassis?

It supports forty eight SFP+ ports, six QSFP+ ports, three PSUs, and multiple console/USB interfaces.

What must I do before downgrading the Dell EMC Networking OS version?

Before downgrading from 9.14(1.10), save your current configuration and then delete the CDB files using specific `delete flash` commands.

What happens if I use a non-Dell qualified 40G transceiver port?

The switch places the interface in an 'error-disabled' (operationally down) state and generates a corresponding syslog message.

What is the potential risk associated with fan subsystems in the S4048-ON?

If all three fan trays are found to be empty or faulty, the system will automatically shut down after one minute.
