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.
5
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

CHAPTER 5: Troubleshooting
5.0 Troubleshooting
This chapter explains basic steps to take in the event of a problem with the
installation or operation of the RISC Router Expandable. If your problem is
not solved after these steps refer to the RISC Router Network Control Guide.
5.1 Troubleshooting Steps
Check for the problems with your RISC Router Expandable.
a. With the power down, be sure the three-pronged plug is properly
connected to the AC DC port of the RISC Router Expandable.
b. Verify that the BNC (ThinNet—blue cable), AUI (Thick Ethernet—thick
orange cable), or MAU cable is attached to the appropriate connector
on the RISC Router Expandable for LAN.
c. Verify that the WAN cable is attached tp the WAN connector onthe
back panel of the RISC Router Expandable for WAN Operation.
d. Verify that the WAN jumpers are correctly configured for the interface
you are using on the WAN port of the RISC Router Expandable.
e. Is the FAULT LED on?
f. (BNC only) Check the terminator switches on the back panel of the RISC
Router Expandable.
Check for problems with your network.
a. Verify that the interconnecting network cables meet the IEEE standard
for cabling and Ethernet LAN and WAN.
b. Verify the cable connection to other computers in the the network.
In a network using Thin Ethernet (BNC) cabling, check all systems
that are daisy-chained to the system your are troubleshooting.
c. Determine whether or not your system is the only one in the network
with a problem.
If none of the steps listed above solves your problem, see the RISC Router
Network Control Guide or call your supplier.
