Upgrading Tips
If you have a number of installed units to upgrade you may not need to move them in order to
upgrade.
Example: To upgrade a number of Local Units installed in a rack you may find it much
faster to bring a Remote Unit & USB KB into the same room as the Local Units. To upgrade
each Local Unit in turn simply connect a patch cable from the Remote to the Local Unit and
then enter the Upgrade Mode entry sequence on the remote KB. Now, with the aid of a flash
drive (or upgrade file located on a shared drive), you may simply upgrade the Local Unit (by
dragging the file on to the extender drive) and then delete the BOOT file before moving on to
the next unit.
Example: To upgrade a number of Remote Units you may find it much faster to use a
patch cable to connect (in turn) each Remote Unit to a nearby notebook which has a Local
Unit connected.
When upgrading a number of units, ensure the BOOT file is
deleted after
each
upgrade is complete. If you forget to do
this and are left with a Local or Remote Unit that is stuck in
Upgrade Mode (orange LED lit), simply re-power the unit to which it
is connected. Both units will now re-enter Upgrade Mode to enable
you to delete the BOOT file and return to normal operation.
After upgrading your extender it is good practice to put a label on the
underside of the unit(s) to indicate which firmware version has been
installed.
