NOTICE: Trunked GPW 8000 Receivers in a circuit simulcast configuration are not
supported using a site software download.
Single Device Software Download
Allows you to transfer and install software to a single instance of a device (such as one base radio).
This feature gives the technician the ability to install different versions of software. Single device
software download is done from a service computer/laptop loaded with the CSS application either
connected directly to the device or connected to the network.
NOTICE: Conventional devices and 3600 base radios are supported only in single device
software download.
Site Software Download Functionality
When SWDL is connected from a central remote location, SWDL performs a site software download to
the site controllers, then to the comparators and base radios or receivers installed at the site. Both
active and standby site controller modules have two flash memory banks for storing software. The
device application is run from RAM, and is loaded from the active flash memory bank after a reset. One
bank is active while the other bank is inactive. The transfer of the software using SWDL is a
background process, without interruption of services at the site, that loads the software into the inactive
bank. The site controller executes the software from one bank, while software is simultaneously
downloaded to the inactive bank. The transfer and install are done in the background. An install causes
the site controller to reset and load the RAM from the bank that was installed with the new software.
NOTICE: For geographically redundant prime sites, a site software download should not be
attempted while the third Site Controller (SC3) is in the active state.
SWDL communicates with the site controllers to determine the number of existing remote sites and the
number of channels. SWDL considers a channel or remote site to be accessible if its status is “Not
Unconfigured.” This term means that the site must be set up with a service computer/laptop with CSS
or a network management client before software download is performed on the site.
The system downloads software to the site controllers, comparators, base radios, or receivers as a
unit. Use SWDL to transfer software to each device type, then perform an install operation. During the
transfer, the operation designates a proxy for each device type at each LAN. Site controllers proxy for
comparators, and base radios or receivers proxy for each other. The proxy cross-transfers the software
to other devices on the LAN. Using proxies minimizes system downtime. Transfers to the LAN are
done simultaneously except for the site controller and comparators.
Software installation is done on a channel-by-channel basis, starting with the highest number channel.
When a channel software download occurs, the base radio or receiver which incorporates that channel
is processed along with the comparator for that channel. For example, if channel 3 was being
downloaded, comparator 3 and the base radios or receivers for channel 3 at each of the remote sites
would be installed simultaneously.
SWDL operation can be fault managed through Unified Event Manager (UEM), syslog, local SWDL log
files, user messages, and device reports.
For further information on SWDL, see the Software Download Manager manual.
The operating software can also be loaded using the UNC. See the Unified Network Configurator
manual to perform single device software downloads (ruthless download) to the devices.
See the G-Series Equipment System Release User Guide for SWDL instructions specific to the
operating characteristics of your existing system release.
