RISC ROUTER EXPANDABLE

2.0 Introduction

This chapter describes the RISC Router Expandable inter-networking

platform, and contains information on the following:

• Major components

• Connectors (with pin assignments)

• Cables (with pin assignments)

• Hardware specifications

2.1 General Description

The RISC Router Expandable is a state-of-the-art RISC-based intelligent

bridge/router, employing the AMD®29000 microprocessor. The RISC Router

Expandable is a transparent network inter-connection device operating on

the MAC layer, level 2, of the OSI model. The RISC Router Expandable

currently routes TCP, IP, IPX™, and XNS protocols and bridges all others.

With eight Ethernet expansion slots, the RISC Router Expandable supplies

a variety of mixed-media hardware interfaces. The RISC Bridge/E Expansion

Card (LB521C) supports three interfaces:

• A Media-Access Unit (MAU) interface — a standard 15-pin male

connector. You can connect a workstation directly to this interface.

• A ThinNet (BNC) interface — a standard Thin Ethernet connection.

•A Data Terminal Equipment (DTE) interface — a standard 15-pin

female connector for a transceiver.

NOTE

IEEE 802.3 and Ethernet v.2 are identified as simply “Ethernet”

in this text.

The RISC Router Expandable delivers maximum bandwidth at 10 megabits per

second across eight individual LAN Ethernet ports. Peak filtering rates of up to

90,000 64-byte packets per second and forwarding at full Ethernet line speeds

of 56,000 64-byte packets per second are achieved under ideal conditions.

For wide area network connection, the RISC Router Expandable provides two

RS-449 serial links. The WAN interface supplies two high-speed transparent

serial channels operating at 384 Kbps. These channels provide a single logical

connection to a remote RISC Router Expandable while balancing the traffic

load over the two channels.

CHAPTER 2: Introduction

The RISC Router Expandable currently supports the following wide-area

network protocols:

• X.25

• Frame Relay

• Point-to-point

• HDLC raw

The RISC Router Expandable is equipped with 1 CPU board, 1 PROM card,

and up to eight expansion cards. A network control port is standard and

supports a user-interface via any VT100™ compatible terminal. Each Ethernet

card is equipped with an Ethernet terminator switch. The RISC Router

Expandable operates on 90-132/175-264 VAC, (47-440 Hz) and meets all

regulatory power-safety requirements.

The Network Control program is the user interface to the RISC Router

Expandable and provides the software tools for the internetworking platform.

Depending on the hardware and software configuration of the RISC Router

Expandable, Network Control provides the following:

• TCP/IP routing, IPX/NetWare®routing

• Protocol-transparent, high-speed bridging

• Multiple logical bridges

• Ethernet switching

• Telnet™, SNMP

• Spanning Tree

• Custom-address filtering

• Network statistics

• Password-protected security

2.2 Front-Panel Components

This section describes the front panel of the RISC Router Expandable.

The numbers in Figure 2-1 correspond to the numbered descriptions below:

1. Port Activity LEDs — The Port Activity LEDs (green) indicate traffic on

the ports of the RISC Router Expandable. Each port has a corresponding

LED that lights when that port is active. The ports are shown from 1

through 8.

2. FAULT LED — The FAULT LED (amber) indicates a software problem.

The software triggers a hardware timer once a second. If it fails to do so,

the FAULT LED lights.

3. PWR OK LED — The PWR OK LED is green when the unit is ON.

CHAPTER 2: Introduction

2.3 Back-Panel Components

This section describes the back panel components of the RISC Router

Expandable. The numbers in Figure 2-2 correspond to the numbered

descriptions below:

1. AC Power Port — The AC power port is a three-pronged grounded AC

input port for the RISC Router Expandable. The unit uses 110 or 220

VAC and automatically configures to the appropriate voltage.

2. ON/OFF Switch — The ON/OFF switch provides power to the RISC

Router Expandable. The “1” indicates ON. The “0” indicates OFF.

3. Reset Switch — The switch is reserved for future use.

4. FAULT LED — The FAULT LED (amber) indicates a software problem.

The software triggers a hardware timer once a second. If it fails to do so,

the FAULT LED lights. This LED is the same as the FAULT LED on the

front of the RISC Router Expandable.

5. Wide Area Network (WAN) Port(s) — The two WAN ports provide

remote transparent bridging. Each WAN port has a male DB37

connector. You can jumper the signaling on the two ports to meet either

RS-423/RS-232, RS-422, or V.35. The signal definitions for the EIA-530

specification follow the RS-422 specification. The V.35-compatible

interface is typically an M-block connector. The pin assignments for

these connectors are in Table 2-1.

6. RS-232 Serial Port — The RS-232 serial port is a DB25 connector used

to provide access to the Network Control program via VT100 compatible

terminal. The pin assignments used in the RISC Router Expandable

RS-232 port are listed in Table 2-2.
