10 | The S4820T Switch
www.dell.com | support.dell.com
The S4820T switch runs the Dell Force10 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
Features
The S4820T has the following features:
• Forty-eight 1/10Gbps RJ-45 ports
• Four fixed 40Gbps QSFP+ ports for 40Gbps transceivers
• One universal serial bus (USB Type-A) port for additional file storage
• On-board high-performance central processing unit (CPU) system with large memory, P2020/128 MB
NOR Flash/2GB DDR III RAM.
• Temperature monitoring (TMP75)
