87.15 Firmware Upgrade
You can upgrade the Switch’s firmware through Web Configurator or NCC.
Firmware Upgrade Through NCC
In cloud management mode, NCC will first check if the firmware on the Switch needs to be upgraded. If
it does, the Switch will upgrade the firmware immediately. If the firmware does not need to be
upgraded, but there is newer firmware available for the Switch, then it will be upgraded according to
the firmware upgrade schedule for the Switch on the NCC.
On the NCC web portal, go to Site-wide > Configure > Firmware management to schedule the firmware
upgrade time.
Note: While the Switch is rebooting, do NOT turn off the power.
Firmware Upgrade Through the Web Configurator
Use the following screen to upgrade your Switch to the latest firmware. The Switch supports dual
firmware images,
Firmware 1 and Firmware 2 . Use this screen to specify which image is updated when
firmware is uploaded using the Web Configurator and to specify which image is loaded when the
Switch starts up
.
Note: Make sure you have downloaded (and unzipped) the correct model firmware and
version to your computer before uploading to the device.
