NOTE: The RJ-45 ports on the I/O side are labeled 0-47. When you cable these ports, be sure not
to interfere with the airflow from the small vent holes above and below the ports.
The S4820T switch runs the Dell Networking operating system (FTOS), providing switching, bridging, and
routing functionality for transmitting data, storage, and server traffic.
In a data center network, the S4820T switch provides converged network support and inter-operates
with Dell and third-party ToR devices. The switch supports data center bridging (DCB) features and
optimizes connectivity between servers and storage devices using Fibre Channel over Ethernet (FCoE)
and internet small computer system interface (iSCSI) links.
By providing increased 40GbE bandwidth for device interconnection in a shared network storage
environment (with the possibility of splitting 40GbE quad small form-factor pluggable plus (QSFP+)
uplinks into four 10GbE SFP+ or RJ-45 connections), the S4820T switch is perfectly positioned to help
transition a data center with multiple speed requirements.
Additionally, the S4820T solution is optimized to provide 10Gbps throughput for distances of up to:
• 330 feet (100 meters) over Cat6, 6A, and 7 shielded copper cable and Cat6A UTP copper cable
• 181.5 feet (55 meters) over Cat6 UTP copper cable
