Main and Management Ethernet Switch Cards

TC3840-1 and -2
Rollover or Touch for Expanded View. Scroll to Zoom.


The JumboSwitch Main (TC3840-1) and Management (TC3840-2) plug-in cards provide layer 2 switching functionality and the central switching fabric for JumboSwitch interface cards. Each 2U/4U 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 CLI, Telnet & SNMP
  • 2-Port SFP Gigabit for Main Card
  • 1-Management Port and 1-Console Port for 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.

There are two types of Main & Management plug-in cards: individual (TC3840-1 & TC3840-2) and combination (TC3840-3). JumboSwitch 2U & 4U chassis options use individual cards and 1U & 2S options use the “combo card.”
