1.0 The UCX Imager Tool

Before using the UCX Imager tool to modify existing systems, you should ensure that the Imager tool software and the Platform Images has been updated using the procedures described in Section 1.2 and Section 1.3 of this document. To minimize time spent on-site and avoid potential network connectivity related issues that prevent accessing the UCX repositories while on customer site, E-MetroTel recommends updating the tool and images before any planned site visit.
E-MetroTel HIGHLY RECOMMENDS that you perform the UCX Imager Tool update in your office or lab environment to ensure that the Imager is able to connect to the internet. Also note that there are some older UCX 250 hardware platforms that have an older BIOS version that can cause issues with the UCX Imager USB operation. It is recommended that the UCX Imager Tool updates be performed on non-UCX 250 hardware to avoid this potential impact.

1.0 UCX Imager tool (USB Stick)

The UCX Imager Tool has been developed by E-MetroTel as a multi-purpose tool, with the first primary applications of its capabilities to be to enable UCX Release 6.0 systems to be easily and efficiently reimaged or factory reset to the UCX Release 7.0 software. As such, care was taken in selecting a USB device that meets our anticipated needs for capacity as well as read and write times. This is important for building the initial image on the USB, as well as for optimizing the time it takes to update the the software on the Galaxy hardware platforms.

The UCX Imager Tool is Part Number: SBUSBN-V7, UCX Imager Tool (7.0 SW Upgrade USB).  It is orderable as a separate item under the Quotations and Ordering section of the E-MetroTel Partner Portal. In the Quotation and Ordering main page, select the Appliance option, choose New System, open the Hardware sub-section and request a quantity you require.  There is no requirement to include any other hardware or software on the same quote.  If you have multiple technicians covering specific customers or regions, you may wish to order more than one however the same USB Imager Tool can be used on any number of Galaxy appliance systems.

It is shipped as a USB stick with green lanyard in a plastic bag as shown below:


Note that one copy of this tool may be used to reimage or Factory reset any number of Galaxy systems.

1.1 UCX Imager Options

The UCX Imager has multiple options:


The following is a brief description of each of the options.

  1. Perform an Reimage to R7 to existing systems while attempting to retain the following non-telephony related configured data:
    • Host ID
    • Network configuration for Ethernet 0, Ethernet 1, Ethernet 2 interfaces if they exists
    • VPN configuration if it exists (VPN connection will need to be restarted after completion)
    • SSL certificate information (regardless of SSL provider)
    • DHCP configuration
    • IP Block List - configuration
    • Firewall configuration
    • Activation state
    • NTP settings and Time Zone preference
    • Hostname
    • Analog Trunk tuning parameters (fxo.tune)
  2. Perform a Factory Reset of a system
    • This process creates a new clean factory image. This will not preserve any data associated with the system it is being applied on. It will reset everything to factory defaults, although it will attempt to retain the system identity, specifically the Host ID and associated licenses.
  3. You may Shutdown UCX will power down the UCX without making any changes
  4. You may Update UCX Imager Software in order to obtain the latest UCX Imager software (Refer to Section 1.2).
    • This option is available only when there is internet access.
  5. You may Update Platform Images in order to add additional UCX images for other platforms (Refer to Section 1.3).
    • This option is available only when there is internet access.
  6. You may Quit in order to safely exit the UCX Imager tool.
If you do not see the Update UCX Imager Software and Update Platform Images it is beause the UCX Imager Tool does not detect a connection to the Internet. This may happen, for example, if you have configured the UCX Ethernet 0 interface to use DHCP. You may still use the other options presented in the list. To resolve, set the UCX Ethernet 0 interface with a static IP Address.

1.2 Updating the UCX Imager Software

Prior to using the UCX Imager Tool on one or more systems, E-MetroTel advises making sure you have updated to the latest version of the UCX Imager Tool software.
