Designed specifically for 2U chassis options, the JumboSwitch Main (TC3840-4) and Management (TC3840-2) plug-in cards provide layer 2 switching functionalities and the central switching fabric for JumboSwitch interface cards. Each 2U chassis must include both a Main and a Management card to function properly.

Optional interface cards communicate with the Main and Management Cards through the backplane, which contain both Data & Control buses. Together, the Main and Management cards provide the "intelligence" for the entire JumboSwitch network platform and serve as both the JumboSwitch’s central processing unit and as the control bus access point for JumboSwitch management.

  • Provides Layer 2 Switching Functionality
  • Fully Managed via Web, CLI, Telnet & SNMP
  • 2-Port SFP + 4-Port 10/100/1000 Gigabit for the Main Card
  • 1-Management Port and 1-Console Port for the Management Card
  • Built-In Power/Temperature Sensors
  • Industrial Hardened & IEC 61850-3, IEEE 1613 & NEMA TS-2


All JumboSwitches must include Main and Management plug-in cards to operate properly. The Management Card functions as the JumboSwitch’s central processing unit and the Main Card is the control bus access point for JumboSwitch management. Together, these cards provide the "intelligence" for the entire JumboSwitch network platform.

Because the Model TC3840-4 Main Card also provides two SFP Gigabit ports and four copper 10/100/1000 Ethernet ports, it benefits users by enabling space for another interface card or eliminating the need for an additional Ethernet card. (The JumboSwitch 2U chassis can hold 1 main, 1 management and up to 2 interface cards).
