Product Overview
The NetlinkTM FRX4000 is used to provide concentration and access
to remote devices. Each FRX4000 supports up to eight serial inter-
faces. (The FRX6000 isgenerally used where more than eight serial
interfaces are required.) The FRX4000 provides local and remote
switching, and (on devices with video interfaces) features an intu-
itive, menu-based management structure that allows complete local
and remote control of other Cabletron frame relay devices in the
family ofFRX4000,FRX6000, SmartSwitch 1800, and 9W004.
Detailed product descriptions can be found in the Netlink FRX4000/
FRX6000 User Guide.
AbasicFRX4000 containsfour serialports forconnection toa frame
relay or X.25network,user devices, and/or other Cabletron frame
relay devices (FRX4000, FRX6000, SmartSwitch 1800, 9W004).
Each FRX4000 also contains one LANinterface, either Ethernet or
Token Ring. An optional serial expansion card offers four more
WAN ports.
Figure 1-1 I/O Ports on theFRX4000
The main board on the FRX4000 supports four serial
ports. If the CSU/DSU port is used, WAN port 1 is dis-
abled.
I/Ocables are available for WAN ports 0–7 in several configura-
tions, described in Appendix A.

LAN Interfaces
The Ethernet model of FRX4000 contains an Ethernet interface, pro-
videdin RJ-45 (fortwistedpair) and15-pin“D” (AUI, for Thicknet)
configurations. The Ethernet cable and, if AUI, the tranceiver, must
be provided by the customer.
The Token Ring model of FRX4000 contains a Token Ring
interface, provided in RJ-45 (for unshielded twisted pair) and 9-pin
“D” (for shielded twisted pair) configurations. A Token Ring cable,
Cabletron number FRX-TR-CAB, is available.
Operator Interfaces
The FRX4000 doesnot require anyoperator intervention for normal
operation. However, a keyboard and video device are necessary for
initial configuration, and can be helpful later for monitoring.
Each FRX4000 is shipped with cables that allow connection to an
ASCII terminal by any of three methods: direct connection to ter-
minal, connection to terminal via modems, or direct connection to
PC running terminal emulation software.
A keyboard and video device can also be connected via one of these
methods:
●ASCII terminal/keyboard (or PC with terminal emulation
software) connected to an async PAD portin the local
FRX4000.
●ASCII terminal/keyboard (or PC with terminal emulation
software) connected to an async PAD portin a remote
Cabletron frame relay device (FRX4000, FRX6000,Smart-
Switch1800,9W004),through anetwork,into anX.25portin
the local node.
