Software Download Options
Immediate Software Activation (Enable/Disable)
The IMMEDIATE SOFTWARE ACTIVATION mode is controlled from the
SYSTEMS UTILITIES/SOFTWARE DOWNLOAD MENU. When the
IMMEDIATE SOFTWARE ACTIVATION feature is enabled, the software
download (using MSR, Xmodem, Kermit, TFTP) is immediately activated
(that is, copied from RAM to FLASH and rebooted).
For consistency with the previous software version, IMMEDIATE=enabled
is the default setting. If the IMMEDIATE SOFTWARE ACTIVATION
feature is disabled, the software download (using MSR, Xmodem, Kermit,
TFTP) is not activated (that is, not copied from RAM to FLASH and not
rebooted).
You must activate the software at a later time by issuing a software
download activation command from the System Utilities/Download
Software/ RAM SOFTWARE OPTIONS selection field. When the software
activation command is executed, the system copies the software image
from RAM to Flash and reboots.
A system restart (power cycle) that occurs after the download, but before
the activation, will not activate the new software. Loss of power causes the
non-activated software download to be lost.
Download Destination (Local Unit, Remove Unit, Both Units)
This feature provides software to be loaded to either the local unit, the
remote unit, or both. Use of the Remote or Both option requires use of the
Xmodem or Kermit protocol.
A file image loaded to the remote unit is sent over the proprietary
IMUX Embedded Data Link (EDL). The EDL is available regardless of
the E1 line coding and framing.
To download to the Remote Unit, you do not log into the Remote;
instead you select the download destination using the Download
Destination field which allows a download to both units at once. It also
minimizes disruption to the terminal interface session when the
Remote Unit does an immediate software activation (which involves
that unit’s rebooting).
