Understanding the ARN/DC Module Locations
In addition to an Ethernet base module, the ARN/DC supports an optional
expansion module and up to two wide area network (WAN) adapter modules
(Figure 1-4
).
Figure 1-4. ARN/DC Module Locations
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
ARN expansion modules provide additional Ethernet (AUI and 10BASE-T) and
serial interfaces. Each ARN WAN adapter module provides an additional serial,
ISDN BRI, V.34 modem, T1/FT1, E1/ET1, X.25 PAD, or 56/64K DSU/CSU
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.
