Figure 5: Location of Jumpers
The FRAME STATUS jumper J2 located at the front of the module determines
whether local faults (as shown by the Local Fault indicator) will be connected to the
7700FR frame's global status bus.
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.
The UPGRADE jumper J10 located at the front of the module 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 Jumper
J10 into the UPGRD position. Install the Upgrade cable provided (located in the
vinyl pouch in the front of this manual binder) onto header J1 at the card edge. Re-
install the module into the frame. Run the upgrade as described in the Upgrading
Firmware chapter in the front of the binder. Once the upgrade is completed, remove
the module from the frame, move J10 into the RUN position, remove the upgrade
cable and re-install the module. The module is now ready for normal operation.
