Error Messages
This table lists some error messages and possible
solutions.
Connecting Devices
Use the following discussion to connect asynchronous
devices to the RocketPort Serial Hub Si ports.
Note: Make sure that you have configured the ports
using the driver for the correct communications
mode before connecting any devices. The default
mode is RS-232. There is a remote possibility
that connecting a peripheral configured for the
wrong mode could damage the peripheral.
1. Connect your devices to Ports 1 through 4 or 8
(depending on the model), for each RocketPort
Serial Hub Si using the appropriate cable or you
can build your own cables using the
Building Null-
Modem Cables or Building Straight-Through
Cables discussions.
Note: Use the hardware manufacturer’s installation
documentation if you need help with connector
pinouts or cabling for the peripheral device.
2. Install or reconfigure the driver using the Software
Installation documentation or the driver readme
file.
Building an Ethernet Crossover Cable
If you are connecting from the
10Base-T connector on the
RocketPort Serial Hub Si
directly to the NIC card in the
server, you need a crossover
cable. Use the following
information to build or
purchase a cable.
DB9 Connector Pinouts
Use the following pinout
information for the DB9 serial port
connectors on the RocketPort Serial
Hub Si.
Building Null-Modem Cables
Use the following figure if you need to build a null-
modem cable. A null-modem cable is required to use
the bootable diagnostic, the IP Configurator utility, and
for connecting DTE devices.
Note: You may want to purchase or build a straight-
through cable and purchase a null-modem
adapter.

4. The RocketPort Serial Hub Si
power was not turned off and
then on before running the
utility.
5. Port 1 is failing and the utility
