(1) To manually update firmware from FTP or web server, enter the URL where the firmware update package is stored and click the ‘update’ button. For convenience purposes, NComputing has provided the following HTTP URL which can be used for the firmware update (note the URL is case sens:
LEAF OS firmware update file (3.3.13): http://firmware.ncomputing.com/LEAFOS/LEAFOS-3.3.13.upd
RX420(RDP) and RX-RDP+ firmware update file (3.3.12): http://firmware.ncomputing.com/RX420/rx4x0-rdp-3.3.12.upd
(2) To manually update firmware from a connected USB memory stick, connect a USB memory stick (which contains the new firmware update file), and select the ‘Update from the USB memory stick’ option.
Update remotely via PMC Endpoint Manager:
Alternatively, the LEAF OS, RX420(RDP) and RX-RDP+ firmware can be remotely updated via PMC Endpoint Manager Software (version 2.7.0 and higher). The firmware update will take less than 1-minute once the firmware is downloaded to the device. Please do not turn off your device during this time. Once the firmware update is complete, the device will reboot automatically.To ensure smooth transition and uninterrupted management ability, NComputing suggests updating PMC to version 2.9.4 (latest version) before upgrading devices to LEAF OS version 3.3.13 and RX420(RDP)/RX-RDP+ version 3.3.12.PMC 2.9.4 comes with the device configuration definitions for LEAFOS(x86) v.17, RX420(RDP) v.17 and RX-RDRDP+ v.13 already available.
