6. Run the Upload utility. The User should follow the instructions presented on the screen, and
the upload will take place automatically.
Following the successful upload process, the Switch will automatically restart, running the new
version of firmware. During this process, the non-volatile RAM storing the configuration of the
Switch will be erased, so the User is then required to re-enter the desired configuration.

5.5.3 CRS-300 Front Panel Configuration
The CRS-300 should show a GREEN “Unit Status” LED. If it is RED, go to MONITOR Æ
SW-ALARM to view the faults. Ensure that the preceding Redundant Modem setup is complete
and that it is operating correctly before proceeding.
Use the front panel keypad and display to configure the Switch as described in the following
paragraphs.
5.5.3.1 Activate Traffic Modems
The CRS-300 was shipped with no Traffic Modems set to “Active”. It is possible to operate
the Switch with only some of the 10 slots filled/occupied. A TMI may only be made 'active' if it
is present. If there are unused TMIs in the Switch, ensure these are de-activated in the
CONFIG Æ
ACTIVE menu. An active Traffic Modem is going to be polled regularly by the Switch.
Activate the desired Traffic Modems as follows:
Step Procedure
1 Go to the CONFIG Æ ACTIVE menu.
2 Activate all desired Traffic Modems, using the [
↑] arrows.
After ENTER is pressed, the Switch Status LED will turn RED, until the Switch has polled each
of the activated modems and correctly programmed the bridged modem configuration into the
Redundant Modem. Once the programming is completed successfully, the RED LED will turn
GREEN
.
The Redundant Modem may take several seconds to configure. If the LED remains red, check the
communication status using the menus to investigate the problem:
MONITOR Æ COMM-STATE or MONITOR Æ SW-ALARMS
Another option is to view the I/O using MONITOR Æ I/O . This menu will show the actual
messages to and from the modems. If there are no responses from a modem, check the addressing
scheme carefully and verify correct modem communication setups. Communication is slowed to
aid viewing.
