GS748Tv4h1 is the first hardware version of latest 48 port Gigabit smart switch with 2 combo ports and 2 dedicated Gigabit SFP ports. GS748Tv4h2 is NETGEAR's new hardware version of GS748Tv4. Compared to the first version GS748Tv4h1, below new features are added.
- EEE (IEEE802.3az)
- IPv4 Static Route.
- IPv6 ACL and QoS.
This SW release 5.4.1.x can both run on GS748Tv4h1 and GS748Tv4h2. And note that EEE (IEEE802.3az) feature can only work on GS748Tv4h2.
GS748Tv4 supports the latest Smart Control Center, please use SCC version 1.1.3.1 for switch discovery, basic configuration and FW upgrades.
Fixed Issues:
- Switch reboots randomly and unexpectedly.
- LAG Link Trap settings reverts to disable on reboot.
- 1000 Mbps Full Duplex should be removed from Port Speed drop down menu.
- Switch forwards all traffic between Vlans during a reboot.
Known Issues:
- IPv6 diffserv fails to match 'other' protocol.
- The deny SNMP rule on management access control does not take effect.
- When EEE is configured with very low sampling-interval (like 30 sec) and cables are plugged in one after the other there is a rare chance of the box rebooting.
Installation Instructions
- Download the new firmware to a convenient place on your local system (e.g., C:\downloads\).
- Start Smart Wizard Discovery Utility, (included on the CD coming with your Smart Switch). If it is not installed, do so now, before continuing.
- In Smart Wizard Discovery window, click Discover to find your Smart Switch. The switch will be listed in the device list table once found. (Note: Smart Wizard Discovery uses broadcast packets to find Smart Switches, which means it can only find Smart Switches in the same routing domain.)
- Highlight the Smart Switch to upgrade and click Firmware Upgrade.
- Follow the screen prompts to complete the upgrade. Smart Wizard Discovery will report a successful completion at the end.
