Fortinet 2 SXRC manual € Blue LED off, € Blue LED on, no display on Sxrc Control Head

Troubleshooting

If your SXRC does not appear to be working, check obvious things first such as blown fuses, poor or incorrect wiring connections, cables and connectors not fully seated, etc.

There is a blue LED located on one end of the SXRC Interface Box. This LED indicates the SXRC is receiving power and is turned on.

€Blue LED off:

¬Verify the external fuse to the Interface Box is good.

¬Verify the power plug is fully seated in the Interface Box. ¬Verify the wiring is correct at the power plug.

¬With a Volt Ohm Meter’s (VOM) negative probe attached to chassis ground check:

;+12 volt power terminal (should read +12V to +16V) ;Remote turn-on terminal (should read +12V to +16V) ;Ground terminal (should read 0V)

¬Verify the internal fuse in the Interface Box is good.

€Blue LED on, no display on SXRC Control Head:

¬Verify the cable from the Control Head is plugged securely into the Interface Box.

¬If using an extension cable between the Interface Box and the Control Head, Verify the connectors are plugged in securely on both ends.

¬If using an extension cable between the Interface Box and the Control Head, Verify the cable is a 6 conductor PS2 type cable.

¬If using an extension cable between the Interface Box and the Control Head, the cable or connectors on it may be bad, try bypassing the extension cable and plugging the Control Head directly into the Interface Box. If this works, then try a new cable.

€Blue LED on, garbage characters in display:

¬Power cycle your system (turn off, wait 3 seconds, turn on). ¬Reset the SXRC form the SXRC SETUP menu.

¬Verify all cables are securely plugged into the Interface Box. ¬Verify all Network Cables are securely plugged in at the Interface Box and SX Series amplifiers.

¬Verify all Network cables are good. If you made these cables check that they are properly wired and terminated.

€Blue LED on, STARTING * displayed for a long time, amplifiers not responding:

¬Does SX Series amplifier(s) scroll SXRC CTL in display? 9If not, then that amplifier is not connected or

communicating to the SXRC.

¬Go back and double check your Communications Network cables and make sure they are inserted properly and ‘snapped’ into place.

¬If you have purchased different cables, double check that they are Straight-Through Ethernet Network cables.

¬If you have made your own cables double check them for secure and proper termination.

¬Check the pins (#1 and #8) in the SX Series amplifiers to make sure they are not bent or damaged.

¬Power cycle your system (turn off, wait 3 seconds, turn on). ¬Reset the SXRC form the SXRC SETUP menu.

€Blue LED on, SXRC display ok, SX Series amplifiers on, garbage characters in SX Series amplifier display, blank SX Series amplifier display:

¬Power cycle your system (turn off, wait 3 seconds, turn on). ¬Perform a Manual Software Update for each amplifier

exhibiting problem.

¬Reset the SXRC form the SXRC SETUP menu.
