Replacing Hardware
Replacing Hardware
Use this procedure to replace a RocketPort Serial Hub ia with another RocketPort
Serial Hub ia in an existing configuration.
1. Disconnect the power from the RocketPort Serial Hub ia that is to be removed
from service.
2. Remove the old unit and attach a new or spare RocketPort Serial Hub ia.
3. Connect the new RocketPort Serial Hub ia to the network hub or server NIC
card.
4. Connect the power source to the new RocketPort Serial Hub ia and verify that
it passes the power on self-test.
5. Change the driver to reflect the MAC or IP address of the new RocketPort
Serial Hub ia.
6. Configure any RS-422 or RS-485 ports to match the previous unit.
7. Transfer all cabling from the old RocketPort Serial Hub ia to the new
RocketPort Serial Hub ia.
No port reconfiguration is needed, providing you reconnect the serial devices
as previously cabled.
8. It is not necessary to shut down and restart the server.
Troubleshooting
If you are having trouble with a RocketPort Serial Hub ia, try the following:
Note: Most customer problems reported to Comtrol Technical Support are
eventually traced to cabling or network problems.
• Verify that the unit is powered on and that the PWR LED is lit.
Note: If the PWR LED is flashing, this indicates that the driver has not
downloaded to the unit.
• Verify that you are using the correct types of cables in the correct places and
that all cables are connected securely.
• Verify that the Ethernet hub and any other network devices between the
server and RocketPort Serial Hub ia are powered up and operating.
• To isolate the unit from the network, use a “crossover” ethernet cable to
connect the unit directly to the NIC card in the server.
• Verify that you are using the correct device driver. Device drivers for the
RocketPort Serial Hub and the RocketPort Serial Hub ia are different.
Note: The drivers used for the RPSH-ia device are the same drivers used for
the RPSH-Si series. For drivers with a GUI, you will select the RPSH-Si
2-port configuration.
• Reboot the server.
• See the Software Installation documentation for information on operating
system specific troubleshooting procedures.
• Verify that the MAC address in the driver matches the address on the
RocketPort Serial Hub ia.
• If you are using IP addressing:
- Verify that the IP address in the driver matches the unique reserved IP
configured address assigned by the system administrator.
- Verify that the server can ping the RocketPort Serial Hub ia. If the ping
fails, there is an addressing or network problem.
