NI 9148 Operating Instructions and Specifications
Removing I/O Modules from the Chassis
Complete the following steps to remove a C Series I/O module from the
chassis.
1.
Make sure that no I/O-side power is connected to the I/O module. If the
system is in a nonhazardous location, the chassis power can be on
when you remove I/O modules.
2.
Squeeze the latches on both sides of the module and pull the module
out of the chassis.
Connecting the Chassis to a Network
Connect the chassis to an Ethernet network using Ethernet port 1 on the
front panel. Use a standard Category 5 (CAT-5) or better Ethernet cable to
connect the chassis
to an Ethernet hub or a computer.
Caution
To prevent data loss and to maintain the integrity of your Ethernet installation,
do
not
use a cable longer than 100 m. If you are using 100 Mbps Ethernet, National
Instruments recommends using a CAT-5 or better shielded twisted-pair Ethernet cable.
If you need to build your own cable, refer to the
Cabling
section for more
information about Ethernet cable wiring connections.
Note
You will configure the IP settings as described in the
Configuring IP Settings
section, after connecting power and powering the chassis on.
The host computer communicates with the chassis
over a standard Ethernet
connection. If the host computer is on a network, you must configure
the chassis
on the same subnet as the host computer. If neither the host
computer nor the chassis is connected to a network, you can connect the
two directly using a crossover cable.
If you want to use the chassis
on a subnet other than the one the host
computer is on, first connect the chassis on the same subnet as the host
computer. Use DHCP to assign an IP address or reassign a static IP address
for the subnet where you want it to be and physically move it to the other
subnet.
Wiring Power to the Chassis
The NI 9148
requires an external power supply that meets the
specifications in the
Power Requirements
section. The NI 9148
filters and
regulates the supplied power and provides power for all of the I/O modules.
