BRIM-A6DP Overview
BRIM-A6DP User’s Guide 1-3
1.3 BRIM-A6DP OVERVIEW
The BRIM-A6DP extends the functionality of your Cabletron Systems
MIM or standalone hub to include remote bridging/routing capability. It
allows remote connectivity usingATM technology.
Using two APIMs on the front panel of the BRIM-A6DP, Cabletron
Systems can offer redundant ATM links from the BRIM to a switched
ATM network. Cabletron Systems provides a variety of APIMs that let
you select the configuration of your choice. If port redundancy is not a
requirement, then only one APIM may be installed.
The BRIM-A6DP supports two types of Virtual Channels: Permanent
Virtual Channels (PVCs), and Switched Virtual Channels (SVCs). It also
supports the ATM Forum’s User-Network-Interface (UNI) for SVC
signaling, and FORE Systems’Simple Protocol for ATM Network
Signaling (SPANS).The BRIM-A6DP allows the user to create LAN
Emulation Clients (LECs), and Virtual LANs (VLANs). Refer to Chapter
3,
Local Management , for information on BRIM-A6DP Local
Management features.
1.4 BRIM-A6DP FEATURES
ATM Port Interface Modules (APIMs)
The BRIM-A6DP supports two Cabletron Systems APIMs for ATM
connectivity and redundancy.You can easily installAPIMs into the BRIM
for the interface of your choice.
APIMs support multiple types of physical layer cable types and are fully
compliant with all ATM Forum specifications.
MIB Support
For additional information on how to extract and compile individual
MIBs, refer to the Release Notes, or contact Cabletron Systems Technical
Support (refer to Section 1.7,
Getting Help ).
LANVIEW Diagnostic LEDs
Cabletron Systems provides a visual diagnostic and monitoring system
called LANVIEW. The BRIM-A6DP LANVIEW LEDs help you quickly
identify bridge and link status.

CHAPTER 2
INSTALLATION
This chapter contains instructions for unpacking the BRIM, installing
APIMs, and installing the BRIM into Cabletron Systems devices that
support BRIM technology.
To install the BRIM and APIMs, you need the following tools:
• Disposable grounding wrist strap (provided with any MIM or hub)
• Phillips screwdriver
2.1 UNPACKING THE BRIM
Unpack the BRIM as follows:
1. Remove the shipping box material covering the BRIM.
2. Carefully remove the module from the shipping box. Leave the
module in its non-conductive bag until you are ready to install.
3. Attach the disposable grounding strap to your wrist (refer to the
instructions on the disposable grounding strap package).
4. After removing the module from its non-conductive bag, visually
inspect the device. If you notice any signs of damage, contact
Cabletron Systems Technical Support immediately.
!
CAUTION
The BRIM-A6DP and the host MIM or hub are sensitive to static
discharges.Use a grounding strap and observe all static
precautions during this procedure. Failure to do so could result
in damage to the BRIM-A6DP or the host MIM or hub.
