Site LAN Network
Agilent Technologies is not responsible for connecting to or establishing communication
with your site LAN network. The Agilent representative will test the system’s ability to
communicate on a mini-hub or LAN switch only.
If you intend to connect your system to your site’s LAN network, you must have an additional
shielded twisted pair network cable (8121-0940).
The IP addresses assigned to the instrument(s) must be fixed (permanently assigned)
addresses. If you intend to connect your system to your site’s network, each piece of
equipment must have a unique, fixed (static) IP address assigned to it.
For a Single Quad GC/MS system, Agilent recommends, sells, and supports the use of a PC
with one (1) network interface card (NIC) and a network switch to isolate the GC/MS system
from the site LAN. The network switch supplied with Agilent systems prevents
instrument-to-PC network traffic from entering the site LAN and keeps site LAN network
traffic from interfering with instrument-to-PC communications. Agilent develops and tests all
Single Quad GC/MS hardware and software using the single NIC configuration and has no
known network configuration issues. Alternate network configurations can be configured
and managed by the end user at their own risk and expense.
For Triple Quad and 7200 Q-TOF GC/MS systems, Agilent recommends, sells, and supports
the use of a PC with two network interface cards (NIC) to provide both a site LAN connection
and an isolated GC/MS system connection. Agilent develops and tests all Triple Quad and
Q-TOF GC/MS hardware and software using the dual NIC configuration, and has no known
network configuration issues. Alternate network configurations can be configured and
managed by the end user at their own risk and expense.
For the 7250 Q-TOF GC/MS systems, Agilent recommends, sells, and supports the use of a
PC with three network interface cards (NIC) to provide a site LAN connection, MS only
connection, and an isolated GC/MS system connection. Agilent develops and tests Q-TOF
GC/MS hardware and software using the triple NIC configuration, and has no known network
configuration issues. Alternate network configurations can be configured and managed by
the end user at their own risk and expense.
