5. JUMPER
CONTROLS
Several jumpers, located at the front of the module are used to preset various operating modes. Figure
4-1 shows the locations of the jumpers.
5.1.
SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper determines whether local faults (as shown by the Local Fault indicator)
will be connected to the 7700FR frame's global status bus.
FRAME STATUS:
To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position (default)
When this jumper is installed in the Off position local faults on this module will not
be monitored.
5.2.
CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
RUN/UPGRADE:
The RUN/UPGRADE jumper is used when firmware upgrades are being done to
the module. For normal operation it should be installed in the
RUN
position. See
the
Upgrading Firmware
chapter in the front of the binder for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the
RUN/UPGRADE jumper J16 into the
UPGRADE
position. Install the Upgrade
cable provided (located in the vinyl pouch in the front of the binder) onto SERIAL
header J27 at the card edge. Re-install the module into the frame. Run the
upgrade as described in
Upgrading Firmware
chapter in the front of the binder.
Once the upgrade is completed, remove the module from the frame, move J16
into the
RUN
position, remove the upgrade cable and re-install the module. The
module is now ready for normal operation.
