To connect your cables, complete the following steps:
1.
Connect one end of your Ethernet cable to your serial device server.
Connect the other end of the Ethernet cable to your Ethernet network.
Make sure you comply with all IEEE 802.3 cabling restrictions.
2.
Secure the power connection by screwing the power connector onto the
power jack of the serial device server. Plug the wall-mount power
supply into an AC outlet of the correct voltage.
Note
National Instruments does not recommend connecting serial devices to your serial
ports until you configure the serial server software as described in Chapter 4,
, and verify the installation as described in Chapter 5,
If you do not intend to verify the installation, you can connect your serial devices at this
time.
For more information about the serial cable connections, see Appendix D,
.
Step 4. Switch on Your Serial Device Server
Before you power-on your serial device server, contact your network
administrator to determine whether you need to configure your network
settings manually using NI Ethernet device configuration or use the
Dynamic Host Configuration Protocol (DHCP) to perform the
configuration automatically.
When you turn on the front-panel power switch, the
PWR/RDY
LED
alternates rapidly between red and yellow while the unit completes its
power-on self-tests and attempts to acquire its network parameters. By
default, the serial device server attempts its network configuration through
DHCP.
The time required for assigning the IP address depends on your network
and the configuration of your serial device server. Allow up to 90 seconds
and observe the state of the
PWR/RDY
LED to determine the outcome of
the self tests. One of the following should occur:
•
A steady yellow
PWR/RDY
LED indicates the serial device server
passed its self tests and acquired its IP address. The unit is now ready
to operate. When using DHCP, the serial device server typically is
ready to operate about 15 seconds after you power it on. Follow the
instructions in Chapter 4,
, to add the serial
ports to your computer.
