Troubleshooting and Technical Support
12. Verify that you are using the correct ports. The
RocketModem 8 mounting bracket and port numbering
scheme are shown in the illustration at right. The port on the
“top” edge of the card is Modem 1, and the port at the
“bottom” edge of the card, nearest the bus connector, is
Modem 8.
13. The RocketPort 8J uses the displayed bracket and numbering
scheme as the RocketModem 8.
The RocketModem 4 uses the same mounting bracket as the
RocketModem 8 and RocketPort 8J, but Jacks 5 through 8
are blocked with blank plugs.
The RocketPort 4J uses four RJ45 jacks. The port at the “top”
edge of the card is Port 1, and the port at the “bottom” edge of
the card is Port 4.
14. If you are using an ISA-bus adapter, verify that the DIP
switch on the adapter is set to an I/O address that matches
the I/O address selection, and that there are no address or interrupt conflicts
with other boards.
15. Use the Advanced Board Options to reset the Scan Rate and IRQ to the
default settings.
16. Make sure the adapter is seated firmly in the expansion slot, and that the
expansion slot screw is in place.
17. If your RocketModem model supports reset, use the RocketModem Reset
utility (rktreset.exe, Page 44) to reset the modem to its default (power-on) state.
18. Shut down the server, reboot from the Diagnostic diskette, and follow the on-
screen instructions to test the hardware.
19. If you are unable to resolve the problem, see Technical Support on Page 48 for
information on contacting Comtrol.
Known Issues In addition to the general tips listed above, we have identified a number of specific
issues and conditions that affect adapter’s performance.
• All products
The Control Panel Add/Remove Software option can be used to remove the
driver, version 1.42 or later. Earlier versions of the driver cannot be removed
through this option.
If you need help removing an earlier driver from your system, see Technical
Support on Page 48 for information on contacting Comtrol technical support.
• All PCI-bus products
PCI-bus I/O addresses are slot specific. If you want to move a RocketPort or
RocketModem from one PCI slot to another, you must use the Device Manager
to remove the board first, then shut down the system, remove the adapter, and
reinstall it in the new slot.
If you move or remove a PCI-bus adapter without first removing it in Device
Manager, the system “thinks” the original board is still installed and you must
edit the registry to correct this.
• RocketPort with 3COM/U.S. Robotics Modems
Symptom: Message displays, “The communication device attached to COMxx
is not functioning.”
Solution: Most USR modems come from the factory set to “Load NVRAM
defaults.” Reconfigure the modem to “Load Factory Defaults,” as the driver
issues settings from the mdm*.inf file.
