Frequently Asked Questions
What hardware is supported on the S4048-ON?
It supports 48 SFP+ ports (10 Gbps), six QSFP+ ports (40 Gbps), and includes PSUs, fan subsystems, serial console/USB ports, and a dual core 1.7GHz CPU.
What are the prerequisites for upgrading the Dell EMC Networking OS?
You must uninstall any older Open Automation (OA) packages, upgrade to version 9.14.2.0 or later, and then install the latest versions of OA components like SmartScripts and Puppet.
Why did my interface go down after adding a transceiver?
If you use non-Dell qualified 40G transceivers in a 40GbE port, the switch will place the interface in an error-disabled state. Use Dell certified optics for reliable operation.
How do I remove CDB files before downgrading the OS version?
First, save your current configuration, then execute: `DellEMC#delete flash://confd_cdb.tar.gz.version` followed by `DellEMC#delete flash://confd_cdb.tar.gz`, and finally `DellEMC#reload`.
