Understanding the ARN Module Locations

The ARN is designed to scale to your needs. In addition to either an Ethernet or token ring base module, the ARN can contain an optional LAN expansion module and up to two WAN adapter modules (Figure 1-4).

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)

ARN expansion modules provide additional Ethernet (AUI and 10BASE-T), token ring (STP and UTP), and serial interfaces. Each ARN WAN adapter module adds one serial, ISDN BRI, V.34 modem, T1/FT1, E1/ET1, 56/64K DSU/CSU, or X.25 PAD interface.

The Ethernet 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. See Configuring RMON and RMON2 on BayRS Routers for information about how to enable and use each RMON data collection implementation.
