Connecting to a Private LAN:
A private LAN is a network in which LAN-enabled instruments and
computers are directly connected, and not connected to a site LAN.
They are typically small, with no centrally-managed resources.
1 If you have not already done so, install the Agilent IO Libraries
Suite from the Automation-Ready CD-ROM that is shipped with
your product.
2 Connect the instrument to the computer using a LAN crossover
cable. Alternatively, connect the computer and the instrument to
a standalone hub or switch using regular LAN cables.
NOTE
Make sure your computer is configured to obtain its address from DHCP and that
NetBIOS over TCP/IP is enabled. If the computer had been connected to a site LAN,
it may still retain previous network settings from the site LAN. Wait one minute
after disconnecting it from the site LAN before connecting it to the private LAN. This
allows Windows to sense that it is on a different network and restart the network
configuration. If you are running Windows 98, you may need to manually release the
previous settings.
3 The factory-shipped instrument LAN settings are configured to
automatically obtain an IP address from the network using a
DHCP server, or using AutoIP if a DHCP server is not present.
You can leave these settings as they are. Most Agilent products
and most computers will automatically choose an IP address
using auto-IP if a DHCP server is not present. Each assigns itself
an IP address from the block 169.254.nnn. Note that this may
take up to one minute.
The front panel LAN indicator will come on when the LAN port
has been configured. If you are unable to communicate with the
instrument, check that a valid IP address has been assigned.
Press the front panel LAN button to view the IP address.
4 Use the Connection Expert utility of the Agilent IO Libraries
Suite to add the N5700 power supply and verify a connection. To
add the instrument, you can request the Connection Expert to
discover the instrument. If the instrument cannot be found, you
can add the instrument using the instrument’s hostname. The
default hostname is described under “Connecting to a Site LAN”.
NOTE
If this does not work, refer to the chapter on “Troubleshooting Guidelines” in the
Agilent Technologies USB/LAN/GPIB Interfaces Connectivity Guide.
