This series of manuals is a replacement for and supersedes the Communications Options Minireference Manual (EK-CMINI-RM). All of the information contained in the Communications Options Minireference Manual is included. Information concerning most of Digital Equipment Corporation’s new communication options, modem products, and Ethernet products has also been included. These manuals will be updated as new communications options, modem products, and Ethernet products are produced. To effectively use these reference manuals and to quickly locate the desired information, it is important that the user be aware of the organization and content of the various manuals. ® Volume 1 contains generic communications information such as: cables, test connectors and terminators, special test programs, and special tools and equipment. Volume 1 also contains information concerning installation and maintenance of some of the communications options. e Volume 2 contains only communications options. Communications options are presented in alphanumerical order beginning in Volume 1 and continuing into Volume 2. e Volume 3 contains information concerning Digital Equipment Corporation’s modem products. e Volume 4 contains information concerning installation and maintenance of Ethernet products. Chapters include Ethernet Devices, Cables, Special Tools and Test Equipment, Accessories, and Network Troubleshooting. Provisions are made for adding information as it becomes available. Option-specific data is located alphanumerically by mptmn designation; that is, DECSA followed by DELNI through H4000. For consistency and familiarity, the material contained in each option-specific section is organized and presented in the same format and sequence; installation data (which includes installation flowcharts, module outline drawings, device/vector address selection, and various other switch/jumper selectable options) is presented first. This material is followed by cabling diagrams, diagnostics (PDP-11 diagnostics, VAX-11 diagnostics, or both), maintenance aids, and Tech Tip/FCO index. 1-1 W%“&,x CHAPTER 2 ETHERNET DEVICES 2.1 INTRODUCTION This chapter contains all information needed to configure, install, and test a variety of Digital Equipment Corporation’s Ethernet devices. The purpose of this chapter is to provide Field Service personnel (trained in servicing Ethernet devices) with a quick reference guide, highlighting important factors concerning installation and maintenance. The information contained in these sections is, therefore, short and to the point. If more detailed information is needed, reference should be made to microfiche, the technical manual, or other reference material concerning that particular device. Each specific section contained in this chapter is organized in alphanumeric order. 2-1 il DECSA INSTALLATION DECSA COMMUNICATIONS SERVER General Description The DECSA communications server is an Ethamm based communication subsystem for local area networks.

M7792 module D2 - D7 Provides a visual indication of the current status of the ROMbased self-test microdiagnostics. All LEDs are lit (ON) following successful completion of the self-test (see Notes 1 and 2). Bulkhead panel Dl Indicates that —15 V transceiver power is available at the bulkhead connector J2. This verifies that: 1. The bulkhead cable assembly is properly connected at both ends, and 2. The bulkhead interconnect panel circuit breaker is properly set. 1. NOTES The self-test microdiagnostic program is initiated each time the DEUNA adaptor is powered up, and takes about 10 seconds to run. During this period, these LEDs blink rapidly as the various functions of the DEUNA adaptor are tested. 2. Whenever the DEUNA protocol enters the RUN state under system software, LED D7 blinks ON and OFF at a one second rate (approximate).

H4000 Ethernet transceivers Ethernet coaxial cable Transceiver cables Etherjack connectors DELNI network interconnects DEREP Ethernet repeaters DECOM broadband transceivers There are two versions of the H4000-T* transceiver tester. e e H4000-TA 120 V/60 Hz H4000-TB 240 V/50 Hz e & & O An H4000-T* transceiver tester verifies a transceiver’s capability to perform the following. Transmit a packet to an Ethernet coaxial cable Receive data from an Ethernet coaxial cable Detect a collision Generate CPT (collision presence test) The H4000-T* transceiver tester operates in two modes. e TX/RX (transmit/receive) mode In this mode, one tester is used to verify the transceiver to which it is connected. The tester transmits a packet to the transceiver, receives these data packets back from the transceiver, and verifies the data packets. e RX ONLY (receive only) mode In this mode two testers are used to verify Ethernet network connectivity. Connectivity can be between a pair of transceivers, DELNI ports, or similar Ethernet ports. One transceiver tester is set in the TX/RX mode while the other tester (set in RX ONLY mode) receives and verifies the data packets transmitted by the TX/RX tester. For specific instructions on the use of the H4000-T* transceiver tester, consult the Ethernet Transceiver Tester User’s Manual (EK-ETHTT-UG). The following illustration shows an H4000-T* transceiver tester. MKVB4-1658 Figure 2 H4000-T* Ethernet Transceiver Tester 4-5 H4080 Loopback Test Connector 4.2.3 The H4080 test connector acts as a “known-good” transceiver to simulate connection to an Ethernet coaxial cable. As such, it provides packet loopback, CPT (collision presence test) signals, and draws normal transceiver current. The H4080 connector may be used to test controllers, repeaters, DELNI network interconnects, and similar devices. The following illustration shows an H4080 connector. Figure 3 H4080 Loopback Test Connector 4.2.4 Tektronix Type 1503 Time-Domain Reflectometer (TDR) The Tektronix 1503 TDR is a portable test device used to measure the length and attenuation of a single Ethernet coaxial cable (see notes). These parameters may be used to accurately determine the distance to cable faults such as shorted, open, or unterminated cable. NOTES 1. For testing baseband (BNE2) cable, a BNC to N adaptor is required. 2. For testing broadband (CAB-6) cable, a BNC to F adaptor is required. The Tektronix type 1503 TDR (or equivalent) is required for certification of the Ethernet coaxial cable. Its features include: e e An oscilloscope-type display, A strip chart (optional) for recording cable ‘“‘signatures’, 4-6 e Selectable impedance levels (50, 75, 93 and 125 ohms), and e Distance calibration switches for entering propagation delay. The following illustration shows a Tektronix type 1503 TDR.
