3.1.2. Arctic Gateway
The Arctic Gateway products have two serial ports; one for console or application (selectable with a
switch) and one for application use only.
The “application” use may be for transparent serial protocols (Arctic GPRS Gateway) or for some
special protocol (Arctic IEC-104 Gateway).
3.2. Firmware images
Depending on the case, you will need either kernel or root filesystem file image, or both. Usually the
files are delivered by Technical Support with MD5 checksums. Checksums can be compared in the
computer before transferred to Arctic, in order to verify the integrity of the files.
3.2.1. Naming conventions
The Linux kernel image
The filename is in form of linux
.<version_number>,
e.g. linux.501
The root filesystem image
The filename is in form of jffs.<
cellular_radio><router/gateway><version_number>,
e.g. jffs.edgerouter508
Note:
• Some filenames do not define the <
cellular_radio>, (which differentiates e.g. the EDGE-
capable Arctics from GPRS -capable ones). The Technical Support will give further
instructions on filenames, if needed.
3.2.2. Availability
The firmware images can be obtained by sending an email to [e-mail]
