Firmware
The firmware for SSE-G3748/D/R/DR-SMIS Ethernet switches resides on a chip on the PCB.
The switch has internal flash memory in two areas to hold two firmware images. The flash area
used for the normal firmware image is referred to as the normal area. The other flash area,
referred to as the fallback area, is used to store the firmware image for fallback purposes in
case of a failure to boot from the normal area.

Firmware Upgrading Procedures

The procedures for firmware upgrading and using a fallback firmware image are listed below.
Upgrading Firmware on the switch using TFTP or the network
To upgrade the switch's firmware, use the procedure below.
1. Designate a server or the network as an TFTP server.
2. Copy the latest firmware to the TFTP root directory on the TFTP server machine.
3. Make sure the upgraded TFTP server and switch both have network reachability.
4. Login to the switch CLI, either through Telnet or a serial console port.
5. Type the command below to upgrade the firmware in the normal area:
firmware upgrade tftp://<ip-address>/<filename>
flash:normal
Here, <ip-address> is the IP address of the TFTP server and <filename> is the name of
the firmware image file.

After a successful download, reboot the switch to use this latest firmware.
