ARN Technical Specifications

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

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. Check also the Documentation Change Notice and Release Notes for related information.

The ARN also supports up to two of the following adapter modules:

•One serial interface

•One ISDN BRI S/T interface
