CHAPTER 1 INTRODUCTION Welcome to the Cabletron Systems HSIM-W87 User’s Guide. This manual describes the HSIM-W87 and provides information concerning features, installation, the use of management, troubleshooting, and specifications. Important Notice Depending on the firmware version used in the HSIM-W87, some features described in this document may not be supported. Refer to the Release Notes shipped with the HSIM-W87 to determine which features are supported.
Chapter 1: Introduction Chapter 2, Installation, describes how to install an HSIM-W87 into an interface module or a standalone device (host platform). NOTE The term “host platform” is used to describe the interface module, or standalone device, into which the HSIM-W87 can be installed. Chapter 3, LANVIEW LEDs, describes how to use the HSIM-W87 LEDs to monitor the HSIM performance and status. Chapter 4, Management, describes the Network Tools needed for configuration for the HSIM-W87.
Overview The HSIM-W87 has its own i960 HD microprocessor used to process data packets, provide simple configuration, Inverse Multiplexer functionality, and statistics processing. The SmartSwitch host platform provides the required logical IP Host services. The HSIM-W87 is designed to be installed in any Cabletron Systems product that supports the High Speed Interface Module. The HSIM-W87 operates in two modes: • Switching • IMUX The first mode, switching, is the default mode.
Chapter 1: Introduction 1.3 DATA FLOW IN THE HSIM-W87 The T3 port receives the DS3 data through the coaxial interface. A T3 framer/Multiplexer strips off the T3 framing and provides 28 individual T1 data streams. The T1 data streams are then terminated by T1 framers, which provide an HDLC bit stream to the HDLC controller. The controller receives data packets from each of the bit streams and places them in a memory subsystem. An onboard CPU examines the packet and notifies the host of its arrival.
Features The primary function of the HSIM-W87 is to provide LAN to WAN access. WAN physical connectivity will be supported through the use of a T3 interface with an unbalanced 75 ohm coaxial cable pair. LAN to WAN connectivity will be supported through HDLC and T1 Inverse Multiplexing (IMUX). The HSIM-W87 interoperates with those Cabletron Systems WAN products that support raw HDLC as the WAN protocol. This support is limited to the CyberSWITCH product line which supports HDLC: • CSX400 – Version 02.00.
Chapter 1: Introduction • The IMUX function is configurable using the Network Tools command, imux, described in Chapter 4. NOTE 1.4.4 Cabletron Systems products that support Inverse Multiplexing (IMUX), such as the HSIM-W87, HSIM-W6, CSX400, HSIM-W84, and HSIM-W85, must exist on both ends of the WAN link for the IMUX function to work. All bridging and switching functions, such as 802.1D, SecureFast VLAN, and 802.
Document Conventions • RFC 1213 (MIBII) support for the Interface Table • Cabletron Enterprise MIBs Refer to the Release Notes included with the host platform for a list of all MIBs supported by the HSIM-W87. For information about how to extract and compile individual MIBs, contact the Cabletron Systems Global Call Center (Section 1.7). 1.4.7 LANVIEW Diagnostic LEDs Cabletron Systems provides a visual diagnostic and monitoring system called LANVIEW.

CHAPTER 5 TROUBLESHOOTING 5.1 TROUBLESHOOTING THE HSIM-W87 Problems in setup can occur in hardware, software, or firmware setups. The following sections detail some of the problems encountered and the possible solution. If a problem persists, contact the Cabletron Systems Global Call Center. Refer to Section 1.7. 5.1.1 Hardware Troubleshooting No LEDs on • Check the host platform to see if it is powered up.
Chapter 5: Troubleshooting NOTE It may be necessary to provide proof of proper configuration of your WAN connection. Service Providers typically require proof that the customer’s equipment is configured correctly before checking their own configuration. Status (STS) LED is OFF The port is operating normally. If it is not, and this LED is OFF, the port may be disabled. Use management to make sure that the WAN interface on the HSIM-W87 is configured correctly.
Troubleshooting the HSIM-W87 5.1.2 Investigating Software Configuration Problems Software problems usually occur when your software configuration contains incomplete or incorrect information. Device not forwarding packets • Ensure that the proper DS1 transmit clock source is configured using the dsx1 command in Network Tools. NOTE When connecting two ds1 devices, one must be tx clock master (local timing) and the other must be slave (loop timing). • Check the DS1 line type.
