Menu-4A Download Utility
The Download feature provides a quick method to upgrade the device
Þrmware. The features are:
¥ Separates the downloading operation from switching to new
operational code, where these operations can be performed at separate
times. The menu lets you set a time when to initialize the Solo E1 DSU
with the new code.
¥ Allows the Solo E1 DSU to store two images of executable code, so you
can switch between the two images.
¥ Enables downloading of the new operation code to be done while the
Solo E1 DSU is operational and passing data. The code can be
downloaded through:
¥ XMODEM via the terminal user interface using an asynchronous
connection.
¥ TFTP from a NMS to the Solo E1 DSU via SLIP with an
asynchronous connection.
¥ TFTP from a NMS to the Solo E1 DSU via SLIP through the
ethernet (with a MAP installed).
Using the Download Utility
Use the DOWNLOAD UTILITY menu, accessed through the Menu-4 Main
ConÞguration, to download software updates, using XMODEM or TFTP.
When switching from one executable image to another, the operational
software in the Solo E1 DSU is restarted, which results in a temporary
service interruption of from one to two minutes.
During the download sequence, while executing the download operation
or when executing from the Boot code, the Power/Test LED alternates red
and green.
