ARN Technical Specifications
114200-E Rev 00 C-3
Hardware Communications Options
The ARN is designed to scale to your needs. In addition to either an Ethernet or
token ring base module, you can add an optional expansion and up to two optional
adapter modules to the ARN.
The ARN is available in the following base module configurations:
• One Ethernet AUI and Ethernet 10BASE-T interface
• One Ethernet 10/100BASE-Tx interface
• One Ethernet 100BASE-Fx interface
• One Token Ring interface (STP only)
The ARN supports the following expansion modules:
• One Ethernet AUI and Ethernet 10BASE-T interface
• One token ring media access unit interface (STP and UTP option)
• Three serial interfaces
• One Ethernet AUI and Ethernet 10BASE-T interface and three serial
interfaces
• One token ring interface (STP and UTP option) and three serial interfaces
The ARN also supports up to two of the following adapter modules:
• One serial interface
• One ISDN BRI S/T interface
Note: The Ethernet AUI and 10BASE-T base and expansion modules can also
contain an optional data collection module (DCM). This optional DCM
gathers Ethernet statistics for a remote monitoring (RMON) utility. A subset of
these statistics is gathered with a built-in RMON function on the
Ethernet10/100BASE-Tx and -Fx interfaces. If your router has both types of
RMON data collection installed, you can run the built-in RMON function or
the optional DCM module, but not both at the same time. If you have one
configured, the other is shut off. Your network administrator can refer to
Configuring RMON and RMON2 on BayRS Routers for additional information
about how to enable and use each RMON data collection implementation.
