3. Verify that the lower green Ethernet LED remains
on to determine that the 10Base-T connection and
the polarity are correct.
4. Verify that the Port 1 LED is blinking. This
indicates that the RocketPort Serial Hub is waiting
for the server PC to download the driver.
Note: The Port 1 LED blinks while the RocketPort
Serial Hub is waiting and goes out when the
server initiates normal program activity.
5. If the port LEDs do not display an error condition,
then you are ready to install and configure the
software. You can find software installation
procedures in the Software Installation
documentation or the device driver readme file.

Adding a Unit to an Existing Installation
Use this procedure to add another RocketPort Serial
Hub to an existing configuration.
1. Install the RocketPort Serial Hub using the
Connecting to the Network discussion.
2. Connect the RS-232 serial devices.
3. Connect the RocketPort Serial Hub to your server
NIC card or Ethernet hub.
4. Power-up the new RocketPort Serial Hub and
verify that it passes the power-on diagnostics.
5. Configure VS-Link to support the new RocketPort
Serial Hub. See the Software Installation
documentation or the driver readme file.
6. Configure the serial ports to support the RS-232
devices.
7. Shut down and restart the server.
“Hot-Swapping” Hardware
Follow this procedure, to “hot-swap” a RocketPort
Serial Hub with another RocketPort Serial Hub in an
existing configuration.
1. Power-down the RocketPort Serial Hub to be
removed from service.
2. Install a new or spare RocketPort Serial Hub.
3. Connect the new RocketPort Serial Hub to the
Ethernet hub or server NIC card.
4. Power-up the new RocketPort Serial Hub and
verify that it passes the power-on self-test.
5. Change the driver to reflect the MAC address of
the new RocketPort Serial Hub.
6. Transfer all cabling from the old RocketPort Serial
Hub to the new RocketPort Serial Hub.
No port reconfiguration is needed.
7. Do not shut down and restart the server.
Troubleshooting
If you are having trouble with a RocketPort Serial Hub
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. Turn the unit’s power switch off and on, while
watching the LED diagnostics. For LED
information, see the
Running the Power On
Diagnostics discussion.
Note: If the Port 1 is flashing, this indicates that
the driver has not downloaded to the unit.
4. Verify that the port polarity is correct. See the
Connecting to the Network discussion.
5. Verify that you are using the correct types of cables
in the correct places and that all cables are
connected securely.
6. Verify that the Ethernet hub and any other
network devices between the server and
RocketPort Serial Hub are powered up and
operating.
7. To isolate the unit from the network, use a
“crossover” Ethernet cable to connect the unit
directly to the NIC card in the server.
