GS748T Beta Firmware Version 1.3.0

There is no customer support for beta firmware. They will ask you to return to a tested release before helping. The beta program is described here.


  • Support for SNMP v1: the GS748T will respond to queries from SNMP-based software.
  • Jumbo frame support: when active, the GS748T will not drop over-sized frames, but will forward them on. Limited to 9,500 byte frames.
  • Spanning Tree: the GS748T will participate in the IEEE 802.1D Spanning Tree protocol to prevent loops
Installation Instructions
  1. Download the new firmware to a convenient place on your local system (e.g., C:\downloads\).
  2. Start Smartwizard Discovery utility, (included on the CD that came with your Smart Switch). If it is not installed, do so now, before continuing.
  3. In Smartwizard Discovery window, click Discover to find your Smart Switch. The switch will be listed in the device list table once found. (Note: Smartwizard Discovery uses broadcast packets to find Smart Switches, which means it can only find Smart Switches in the same routing domain.)
  4. Highlight the Smart Switch to upgrade and click Firmware Upgrade.
  5. Follow the screen prompts to complete the upgrade. Smartwizard Discovery will report a successful completion at the end.
