Rear Panel Troubleshooting
Each rear panel connector is associated with a hardware group in the analyzer. You can
use the data at these rear panel connectors to help troubleshoot these hardware groups in
addition to testing the connectors.
The connectors discussed in this section are:
• USB
• SERIAL (RS-232)
• PARALLEL (1284-C)
• VGA
• GPIB
• LAN
Checking the USB Ports
NOTE
The rear panel contains five USB ports; one “stand-alone USB port” on the
CPU board and a “group-of-four” connected to a separate hub.
To verify proper operation of any USB port:
• Connect a known good USB device, such as a USB mouse.
• Wait 15 seconds for the analyzer to verify the device connection, and then check the
operation of the USB device.
• If the device performs correctly, the USB port is functioning properly.
• If the device does not perform correctly, remove the non-working USB device, wait 15
seconds, and then reconnect the device to the USB port.
• If the device still does not perform correctly, remove the USB device and connect it to
the front panel USB.
NOTE
If the front panel USB port does not work, refer to
.
• If the USB device has been verified to work on the front panel but
not
on the
stand-alone USB port:
— Then the A15 CPU board is faulty. Refer to
“Removing and Replacing the A15 CPU
.
• If the USB device has been verified to work on the front panel but not on one of the
“group-of-four” USB ports:
— Then the rear panel hub is faulty. Refer to
“Top Assemblies, All Options Including
for replacing the rear panel hub board (part number
E8356-60202).
