Adding a Unit to an Existing Installation
Use this procedure to add another RocketPort Serial
Hub Si to an existing configuration.
1. Install the RocketPort Serial Hub Si to an Ethernet
hub or NIC card using the
Connecting to the
Network discussion.
2. Power-up the new RocketPort Serial Hub Si and
verify that the Power LED lights.
3. Configure the driver to support the new
RocketPort Serial Hub Si, using the
Software
Installation documentation or driver readme file.
4. Configure serial ports to support the serial devices.
5. Connect the serial devices.
Note: The RocketPort Serial Hub Si defaults the
ports to RS-232. Make sure that you do not
connect devices until the appropriate port
interface type has been configured.
6. Shut down and restart the server.
“Hot-Swapping” Hardware
Follow this procedure, to “hot-swap” a RocketPort
Serial Hub Si with another RocketPort Serial Hub Si
in an existing configuration.
1. Power-down the RocketPort Serial Hub Si to be
removed from service.
2. Install a new or spare RocketPort Serial Hub Si.
3. Connect the new RocketPort Serial Hub Si to the
network hub or server NIC card.
4. Power-up the new RocketPort Serial Hub Si 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 Si.
6. Configure any RS-422 or RS-485 ports to match the
previous unit.
7. Transfer all cabling from the old RocketPort Serial
Hub Si to the new RocketPort Serial Hub Si.
Note: Make sure that you do not connect RS-422 or
RS-485 devices to ports that are configured
in the driver as RS-232 (default).
No port reconfiguration is needed, providing you
reconnect the serial devices as previously cabled.
8. Do not shut down and restart the server.
Troubleshooting
If you are having trouble with a RocketPort Serial Hub
Si try the following.
Note: Most customer problems reported to Comtrol
Technical Support are eventually traced to
cabling or network problems.
1. Verify that you are using the correct device driver.
Device drivers for the RocketPort Serial Hub and
the RocketPort Serial Hub Si are different.
Note: If you want to run both devices, you must
install and configure both drivers.
2. Verify that the unit is powered on and that the
Power LED is lit.
3. Verify that you are using the correct types of cables
in the correct places and that all cables are
connected securely.
4. Verify that the Ethernet hub and any other
network devices between the server and
RocketPort Serial Hub Si are powered up and
operating.
5. To isolate the unit from the network, use a
“crossover” ethernet cable to connect the unit
directly to the NIC card in the server.
6. Verify that the MAC address in the driver matches
the address on the RocketPort Serial Hub Si.
7. If using an IP address, verify that the IP address in
the driver matches the unique reserved IP
configured address assigned by the system
administrator.
8. Verify that the server can ping the RocketPort
Serial Hub Si. If the ping fails, there is an
addressing or network problem.
9. See the Software Installation documentation for
information on operating system specific
troubleshooting procedures.
10. If you have a spare RocketPort Serial Hub Si, try
“hot-swapping” RocketPort Serial Hub Si units.
See the
“Hot-Swapping” Hardware discussion.
Note: If this corrects the problem, the RocketPort
Serial Hub Si you have removed from service
may be defective or in need of repair.
11. Reboot the server.
12. Remove and reinstall the driver.
13. If you are unable to resolve the problem, contact
Technical Support .
