Product Overview

Bridge/Router Interface Modules (BRIMs) reside in, and provide additional

connectivity/functionality to, various Cabletron MIMs and hubs (e.g. the EMM-

E6 or MicroMMAC). Cabletron’s CRBRIM-W/E remote access router provides

multi-protocol router capability for Cabletron MMAC (Multi-Media Access

Center) modules with BRIM and EPIM (Ethernet Port Interface Module) slots.

The CRBRIM-W/E utilizes a ﬁxed conﬁguration of two WAN ports, and one

internal Ethernet port. The two high density WAN ports support V.35, X.21,

RS449, RS422, RS530, and RS232 interfaces. The CRBRIM-W/E uses Cisco

Systems

routing software and is capable of supporting Frame Relay, X.25, DDN

X.25, SMDS, T1/E1, and DDS circuit connections.

The CRBRIM-W/E uses a FLASH EEPROM and is shipped with system code

operating from Flash memory by default. (For more information on system-code

operation, see Chapter 3, section 3.2 “System Operation Prerequisites.”)

Memory Conﬁgurations

Hardware Installation Guide

Hardware User’s Guide

2.2 Memory Conﬁgurations

The CRBRIM-W/E has the following memory systems:

• Primary memory (main memory)—Dynamic random-access memory

(DRAM) that stores the running conﬁguration and routing tables; mounted on

the system card.

• Shared memory—Shared DRAM that is used for packet buffering by the

router network interfaces.

• System-code memory—Flash or programmable read-only memory (PROM);

stores the operating system software image.

• Boot ROM memory—Stores a subset of the operating system software image

that is called the system bootstrap image or the bootstrap program (or ROM

monitor). The system bootstrap image allows you to boot the router when

Flash memory does not contain a valid system image.

The boot ROM prompt follows: Router(boot)>. The bootstrap program (ROM

monitor) prompt is the greater than sign (>), which differs from the user-level

operating-system prompt of gateway >. (For more information, see Appendix

B, “Virtual Conﬁguration Register,” and Appendix C, “Bootstrap Program.”

• Nonvolatile random-access memory (NVRAM)—Stores the system

conﬁguration ﬁle and the virtual conﬁguration register.

CRBRIM-W/E

CHAPTER 2: Product Overview

Table 2-2 shows possible memory conﬁgurations for the CRBRIM-W/E.

2.3 Protocol Support

The CRBRIM-W/E is hardware encoded at the factory to operate with one of three

router software sets. This provides users with the option of selecting IP,

DESKTOP, or ENTERPRISE routing software at the time of purchase.

1. The router has 2 MB of permanent (fixed) DRAM memory and a DRAM SIMM

socket for upgrading the memory. 1 MB of this permanent memory is used by the

CPU and is called

primary

memory. The other 1 MB of memory is used by the net-

work interface ports to store packets and is called

shared

packet

memory. When

a DRAM SIMM is installed in the DRAM SIMM socket, all of the DRAM memory on

this SIMM becomes primary memory for the CPU, and the 2 MB of DRAM that is

permanent on the board becomes shared memory.

Table 2-2. Memory Conﬁgurations

Memory Type Memory Capacity

Primary memory (DRAM SIMMs) 1 MB (expandable to 4 or 16 MB)

Shared (packet) memory 1 MB (DRAM on board)

System-code memory (Flash or

PROMs)

4 MB (expandable)

Boot ROM 1 MB

Nonvolatile RAM (NVRAM) 32 KB

The CRBRIM-W/E is factory conﬁgured for either IP, DESKTOP

or ENTERPRISE Routing Software. The factory hardware settings

are permanent and cannot be changed to operate a different router

software set.

NOTE

Hardware User’s Guide

The ENTERPRISE router software set provides all Cisco-supported LAN, WAN,

and routing protocols as well as IBM features and protocol translator functionality.

Supported LAN protocols include IP, Novell, IPX, DECnet IV, AppleTalk Phase 1

and 2, bridging, DECnet V, XNS, Banyon VINES, OSI, Apollo Domain, PUP, and

CHAOSnet.

The DESKTOP software set supports IP, Novell, IPX, DECnet IV, AppleTalk

Phase 1 and 2, and bridging.

The IP software set supports IP, and bridging protocols.

All CRBRIM-W/E models are shipped with Frame Relay and X.25 software that

offers efﬁcient remote site access to packet switched networks.

CRBRIM-W/E models conﬁgured for either DESKTOP or

ENTERPRISE Routing Software are shipped with a user

installable 4 megabyte primary memory DRAM SIMM. See

Chapter 6, section 6.1.4 DRAM SIMM Installation for installation

procedures.

Preparing for Installation

This chapter describes the tasks you must perform before starting actual system

installation.

Sections of this chapter follow:

• Preventing Electrostatic Discharge Damage

• System Operation Prerequisites

• Distance Limitations

• Interference Considerations

• Console Considerations

• Network Connection Considerations

• Inspecting the System

3.1 Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry.

It occurs when electronic components are improperly handled and causes

complete or intermittent failures.

Follow ESD-prevention procedures when handling electronic components. Ensure

that the chassis is electrically connected to earth ground. Wear an ESD wrist strap,

ensuring that it makes good skin contact. Connect the clip to an unpainted chassis

frame surface to safely channel unwanted ESD voltages to ground. To properly

guard against ESD damage and shocks, the wrist strap and cord must operate

effectively. If no wrist strap is available, ground yourself by touching the metal

part of the chassis.

3-2

CRBRIM-W/E

CHAPTER 3: Preparing for Installation

3.2 System Operation Prerequisites

The CRBRIM-W/E is designed to run system code from Flash memory single in-

line memory modules (SIMMs). With the proper system code image, the router

also can be run from dynamic random-access memory (DRAM); however, this

operation requires a 4-MB memory upgrade (installation of a 4 MB x 72 pin

DRAM SIMM). Further, operating system code from DRAM can result in a 25-

percent decrease in system performance.

Operating the system code from Flash is the default and is recommended for

optimum performance of the router.

3.3 Distance Limitations

When setting up your router, consider distance limitations and potential

electromagnetic interference (EMI) as deﬁned by the Electronic Industries

Association (EIA). Following are the distance limitation speciﬁcations for serial

interfaces.

3.3.1 Serial Connections

As with all signaling systems, RS-232 signals travel a limited distance at any

given bit rate; generally, the slower the data rate, the greater the distance.

Table 3-1 shows the standard relationship between baud rate and maximum

distance.

For safety, periodically check the resistance value of the antistatic

strap, which should be within the range of 1 and 10 M

Ω
