4.2a Pre-1.5.0 Firmware Update Best Practices
N-series firmware versions prior to 1.5.0 are designed to be applied sequentially, with each new build
applied to the previous build in order of their release. Administrators can manually step a device
through sequential firmware updates if desired, or they can configure the devices to perform a
sequential update automatically.
NOTE: If a device is updated out of sequence and ends up skipping a firmware build,
administrators can simply downgrade the device and reapply the firmware update process from
beginning to end. Furthermore, once the initial step of downgrading a device to firmware
version 1.1.1 (the first public firmware build), the remainder of the update process can be
automated, as outlined below.
Requirements for Automatic, Sequential Updates
An automatic update requires that the devices be set to either of the “automatic” (DHCP* or URL)
update modes (found in Firmware/Wallpaper Update section of the Management Tab in the N-series
GUI) and pointed to a network accessible folder** that contains each of the required firmware builds.
The folder should contain the desired firmware files themselves as well as a catalog.txt file, as pictured
below:
The catalog.txt file functions as a table of contents for the update service; listing each of the firmware
builds in a given archive in the order that they were released. Below is an example of the contents of a
catalog.txt file that contains information for three firmware builds, ranging from build 1.1.1 to build
1.3.7.
Nxxx_FW_ver_1_1_1_1.tar.gz 0 0 0 1 1 1 1 02e90025e8239722e58b62b3a9b92386
Nxxx_FW_ver_1_2_0_1.tar.gz 0 0 0 1 2 0 1 945434214db5285596a24404a637471d
Nxxx_FW_ver_1_3_7_2.tar.gz 0 0 0 1 3 7 2 a4f5dcdeb8de66aaabfe804fc3a5ee93
Each new firmware build is released with a catalog.txt file containing a single line. The above catalog.txt
file contains three lines because it was written for an archive that contains three firmware builds. In the
event that a new firmware build was released, the archive could be updated by adding the firmware file
itself to the folder, and copying the catalog.txt line included with that firmware into the archive’s
catalog.txt file. In this case, the next firmware build would add a fourth line.
* Note that using the DHCP setting requires that DHCP tags be configured with the appropriate FTP
information. See section 4.3 of this manual for more information on this feature.
** If a network accessible folder is not available, or assistance is needed to set up such a resource, an
example is given using FileZilla at the end of this guide.

4.2b 1.5.0 Firmware Update Best Practices
As of version 1.5.0, each new N-series firmware release will include two firmware files.
The first, intended for use as a single-version, sequential update, works exactly as previous firmware
versions. That is, as an update from the last official release to the current release. The second file,
intended as a complete, standalone install of the current firmware, can be used to update a device that
is several versions behind the current release version in a single step; without the need to
progress through each previous version in the order of their release.
This new system offers new flexibility and streamlines the firmware update process when devices are
several versions behind the current release, while retaining the ability to perform rapid, single version
updates using minimal file sizes when possible.
The following sections will outline some of this new functionality and provide administrators with
detailed installation steps for implementing firmware 1.5.0 using a number of different install methods.
Identifying the new firmware files:
The single-version update file and full, standalone update file are differentiated by the first set of digits
in their version number. The full update’s value is incremented by 100, while the remaining digits
remain identical. For example:
Nxxx_FW_ver_1_5_0.tar.gz
single-version sequential update, for use with the previous official release.
Nxxx_FW_ver_101_5_0.tar.gz
full update, usable when a device is several versions behind.
Note that both of these files should be added to your firmware repository before updating to 1.5.0.
Administrators must only direct their devices to the Nxxx_FW_ver_1_5_0.tar.gz file (not the 101.5.0
file). The firmware will automatically use the full update file if the update in question spans more than
two versions.
Installing 1.5.0 via N-series GUI
When installing 1.5.0 on a device for the first time using the device GUI, follow these steps:
1. Ensure both of the firmware files (sequential and full) have been uploaded to an FTP accessible
folder. If you are unfamiliar with this process, consult the FileZilla example in the following KB
document: http://www.ncomputing.com/kb/afile/370/342/
NComputing N-series User Manual rev10.08.13_1.5.0
Page 28 of 38
2. From the N-series GUI, under the Management -> Firmware/Wallpaper Update Tab, select the
URL (Manual) update type and fill out the URL field, using the FTP address of the firmware file.
(again, this will be the 1.5.0 file, not the 101.5.0 file)
This step is essential. The FTP URL must be pointed at the 1.5.0 file. In the event that DHCP tags
are being used, ensure that the DHCP tags have been updated to point at this same file.
3. Once the URL field has been populated, you can perform the firmware update using the method
of your choosing (URL Manual, Automatic, DHCP, etc.).
Installing 1.5.0 via USB Drive*
When installing 1.5.0 on a device for the first time using a USB memory device, follow these steps:
1. Copy the catalog.txt and Nxxx_FW_ver_1_5_0.tar.gz files to the USB storage peripheral and
connect it to the N-series access device.
2. From the N-series GUI, under the Management -> Firmware/Wallpaper Update Tab, select the
USB (Manual) update type and fill out the URL field, using the directory location of the
Nxxx_FW_ver_1_5_0.tar.gz file from step 1.
3. Once the URL field has been populated, you can perform the firmware update.
*NOTE: USB update requires firmware 1.4.1. Feature not present in older versions.
Installing 1.5.0 via vSpace Management Center
When installing 1.5.0 on a device for the first time using vSpace Management Center, start by verifying
that all VMC servers within the Managed Zone have been fully updated to VMC version 3.3.1. Once
that's done, follow these steps:
1. Ensure that the full update file has been uploaded to an FTP accessible folder (this is the 101.5.0
file), and that the sequential update file (1.5.0) has been added to VMC’s firmware repository. If
you are unfamiliar with hosting files via FTP, consult the FileZilla example in the following KB
document: http://www.ncomputing.com/kb/afile/370/342/
2. From VMC, push a profile update to the device(s) in question, setting the FTP URL value in the
firmware update tab to that of the full update file location (this is the 101.5.0 file).
3. Once the profile push has completed successfully, you can initiate a firmware update from
vSpace Management Center to 1.5.0 using the Device Management -> Update firmware menu.

4.2c Directing N-series Devices To The Firmware Archive Using the N-series GUI
Once a folder or archive is set up with the above listed requirements, administrators can configure their
N-series devices on a per-device basis if desired. This process is outlined in the steps below.
1. From the Manage Profiles menu, select the N-series profile you wish to edit. If an N-series
profile does not already exist, use the steps outlined in Section 4.5 of this manual to create a
new profile for the devices you wish to update.
2. Navigate to the Management Tab, and then select Firmware/Wallpaper Update (pictured
below).
3. Using the FTP, User, and Password fields, enter the FTP location of the newest firmware build
within the archive you have created. (this will be a file ending in .tar.gz)
4. When finished, click the Update button to begin the sequential update.
At this point the device will begin the process of updating to the newest version of firmware available
within the archive you have created, proceeding through each of the intervening builds between its
current version and the newest version as outlined within the catalog.txt file.
4.2d Directing N-series Devices To The Firmware Archive Using Device Profiles
If a deployment includes vSpace Management Center, administrators can configure all of their N-series
devices for automatic updates at the same time through the use of Device Profiles. Keep in mind that as
with the device GUI method, the FTP folder and firmware archive must be set up prior to initiating the
update. The process for initiating the update from vSpace Management Center is outlined in the steps
below.
IMPORTANT NOTE: N-series devices must already be running firmware version 1.2.0.1 or newer to
receive a firmware update from vSpace Management Center. If the intended devices are running
firmware older than 1.2.0.1, the device GUI method above must be used instead.
NComputing N-series User Manual rev10.08.13_1.5.0
Page 30 of 38
1. From the Manage Profiles menu, select the N-series profile you wish to edit. If an N-series
profile does not already exist, use the steps outlined in Section 4.5 of this manual to create a
new profile for the devices you wish to update.
2. Navigate to the Firmware Update Tab (pictured below).
3. Check the box next to “Edit settings” setting at the top of the menu, then select “Update from a
specified firmware file on a FTP server”.
4. Using the FTP, User, and Password fields (making sure to re-enter your password in the Confirm
field), enter the FTP location of the newest firmware build within the archive you have created.
(this will be a file ending in .tar.gz)
5. Take a moment to verify that all other profile settings are as you desire (including screen
resolution, XenDesktop settings, etc), and apply the profile from the Summary Tab.
6. If you have not done so already, upload the latest firmware build to your vSpace Management
Center server, using the Manage Firmware menu under the Administration Tab.
7. Once the above steps have been completed, head to the Manage Devices menu under the
Device Management Tab and initiate a firmware update on the devices of your choice, selecting
the most recent firmware version available.
At this point the selected devices will begin pulling updated firmware in the order specified within the
catalog.txt with automatic reboots between each firmware version until the process is complete.

4.2e Example of FTP Folder Setup Using FileZilla
In the case of FileZilla, hosting an existing folder on your host system is a simple process. Once installed,
open the FileZilla server interface and complete the following steps:
1. Click on the Users icon at the top left of the FileZilla Server window.
2. Click the Add button under the Users section to the right of the window and create a new user.
(This will be the user account you add to your NComputing device later in this guide)
3. Add a new folder under the Shared Folders section and select the folder containing your
firmware files. This can be the folder mentioned in the previous section, or any other folder if
you’ve decided to host the files elsewhere. (Note the folder’s path as it will be important later in
this guide)
Your firmware files are now shared and available for download via FTP by your devices.
4.3 DHCP Options for Automatic N-series Configuration
