Figure 2. S4820T I/O-Side View1. 10GBase-T Ports 2. QSFP+ Ports3. USB PortNOTE: The RJ-45 ports on the I/O side are labeled 0-47. When you cable these ports, be sure notto 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, androuting functionality for transmitting data, storage, and server traffic.In a data center network, the S4820T switch provides converged network support and inter-operateswith Dell and third-party ToR devices. The switch supports data center bridging (DCB) features andoptimizes 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 storageenvironment (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 helptransition 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 cablePrerequisitesDetailed installation instructions for the S4820T are provided in Site Preparationsand in Install theHardware sections. To successfully install the S4820T, ensure that you have the following:• S4820T chassis (or multiple chassis, if stacking)• At least one grounded AC or DC power source per chassis• Cable to connect the AC or DC power source to the chassis (US AC power cables included)• Mounting brackets for rack installation (included)• Screws for rack installation and #1 and #2 Phillips screwdrivers (not included)• Ground cable (not included)• Ground cable screws (included)• Copper/fiber cables8 The S4820T Switch
