INTRODUCTION

The DELNI (DIGITAL ETHERNET L.ocal Network Interconnect) unit is an
electronic device which permits work stations (ETHERNET devices) to
communicate by using the ETHERNET network transmission system.
You do not need to know how ETHERNET works to install the unit. You
need only follow the instructions for your work stations and network
system software.

wa ghea B3

This unit can work with DECnet or other ETHERNET communication

software. Under the ETHERNET system, work stations communicate by
using a single coaxial cable, without interfering with each other. The
network system is divided into levels of hardware and software, each level
more technically sophisticated than the previous level. The DELNI unit is

part of the lowest level (the physical level) of the ETHERNET system; it has
no acujustments

DELM1 Arrangements
You c.an contiect up to eight work =tations to a DELNI group called a

standalone DEL~! LAN (Local Area Network).

if work stations in different DELNI LANs need to exchange information,

you can connect DELNI units to each other as shown in the following
figure. One unit can connect to eight other DEL NI LANSs, which lets many

stations communicate with each other. And, you can still connect work
ctations 1o any of the eight DELNI device connectors.

It you plan to have a large ETHERNET system which connects many work

stations or covers a wide area, you can connect DELNI LANs to the

ETHERNET system with an ETHERJACK junction box, or directly to an
ETHERNET transceiver. Refer to Appendix Afor information on connecting

to these devices.

Standalone and Connected Operation
If you use either the two-tier or connected arrangement, you have to use
the ninth connector. Next to this connector there is a switch which
disconnects the DELNI LAN from the larger system and makes this DEL NI
LAN a standalone arrangement. There is no effect on the DELNI LAN or
the larger network You can reconnect the standalone DELNI LAN to the

larger network at any time by switching back to the [J position.

You can add or remove work stations at any time, in either mode, without
disturbing the network.

Installation
Chapter 2 explains how to install your DELNI unit. Before you install your
unit, plan your arrangement. You need to know how long connecting
cables can be so that you can better plan where to place the unit. For this
information, refer to the manuals that come withthe ETHERNET controlier
modules for the work stations you want to connect. Refer
to Appendix Afor
information on connecting to an ETHERJACK box and ETHERNET
network transceiver.
Make sure all the work stations are working correctly before you connect
them to the unit

Rack Mount Option
if you want to mount the DELNI unit ina 19 inch (48 centimeter) rack, you
can get an optional rackmount assembly (DEXRM) from Digital Equipment
Corporation through the DECdirect catalog, or by contacting your local
Digital sales office.

Related Documentation
For more information, the ETHERNET Installation Guide (EK-ETHER-IN)
and the appropriate ETHERNET Controlier Manuals are available.

Bafore You Start
First, make sure all the work stations you plan to connect work correctly.
Next, install the ETHERNET controllers and then your work station cables.

Cables are available with either straight or right angle connectors. If you
mount your unit on the floor, use straight connectors; ctherwise. use
either.
NOTE: Check for any cable length restrictions by referring to the
appropriate installation manual for each station's ETHERNET controller.
Refer to the ETHERNET Installation Guide for more information.

NOTE: It you plan to connect the DELNI! unit to another DELNI unit, an
ETHERNET transceiver, oran ETHERJACK box, you must have a separate
cable (Part Number BNES, ordered separately). Contact your Digital Sales
Office for more information.

1. Open the box and check the contents. Save the box and shipping
material.

TROUBLESHOOTING
Introduction
This chapter explains how to identify problems in your DELNI unit and
perform some simple procedures to fix them.

Green Light Does Not Go On
if the green light on the connector panel does not go on, there may be a
power fault First, make sure there is power at the socket (try plugging a
lamp into the socket). Check the voltage selection switch as described in
Chapter
2 and then check the fuse. If necessary, replace the 0.5 amp time
delay fuse as shown in the figure below. If the light still does not go on, the

unit must be replaced.

MA-063782

Other Hardware Problems
if you have problems using the DELNI unit, the fault may be in the work
station, the cable between the unit and the work station, or the unit itself.
First, run any available diagnostics (refer to the work station’s owner's
manual). If diagnostics do not locate the problem, continue troubleshooting Troubleshooting involves substituting working componegnts,
one by one, until you find the defective component.
s the Work Station at Fault?
i. Substitute a station which you know works correctly for the one that
shows the problem.
2.

Ifthe new station works correctly, the station you just removed is fauity.
Refer to that station's owner's manual for corrective action.

If the problem continues, the cable or unit is faulty.

Is the Cable at Fault?
1.

Remove the connector for the cable between the unit and the station

that shows the problem.

Connect a cable which you know works correctly to this connector.
You can use a cable from another station.

Connectthe other end of this cable to the same station that shows the
problem.

|f the station works correctly the cable you just removed is faulty.

Replace the defective cable.

if the problem continues, the unit is faulty.

g the DELNI unit at Fault?
if some of the DELNI panel connectors are not in use, and some of the
connectors in use are not working, connect working cables and stations to
the unused connectors. The unused connectors may not be faulty. If
different connectors work, use these until you can arrange to have your
unit serviced. If none of the connectors work perform the following test.
1.

Disconnect all cables from the DELNI panel

Substitute a unit which works correctly for the one that shows the
problem.

Connect all cables to the working unit. If all stations work carrectly the
original unit is faulty. Replace that unit.

If the problem continues, then start over with step one above.

Software Problems
The DELNI! unit does not depend on software to operate. Howewver, if you
do not have the appropriate software for your station, you méay have
communication problems.
Make sure you have the latest version of ETHERNET network software
correctly instalied in your work stations. You may want to reload this
software into all appropriate stations before you test again.

ETHERJACK CONNECTION
Connecting Cables to the ETHERJACK Junction Box
This appendix describes howto connectcable to an ETHERJACK junction
box

The ETHERJACK box is a connection point for two cables. You can use it
between two lengths of cable, or as the connecting point for a cable and
other network equipment An H4000 transceiver is not usually accessible
and therefore has a cable connected toit. This cable is installed in the
ETHERJACK box for connection to other network equipment.
There may be restrictions on the total distance between equipment tobe

added and an H4000 transceiver or a second DELNI unit. Check the
installation manual that came with your network equipment or the
ETHERNET controlier for your work station. You may have to rearrange
your equipment if it has restrictions. Typically, the maximum distance you
can have is 50 meters (164 feet, 2 inches), although some work stations
allow less. For example, the DEUNA ETHERNET controilerforthe PDP-11
or VAX can not be more than 35 meters(114 feet, 9 inches) from a second
DELN! unitoran H4000 transceiver. Contact your local Digital sales office
for more information about installing your network system.

Each ETHERJACK box has a specifications label inside the cover. This
label lists the length of the cable that connects the ETHERJACK box to
other network equipment, DELNI unit, or H4000 transceiver. Make sure to
include this length when you calculate total cable length. Another label
inside the ETHERJACK cover shows several cable arrangements.

Perform the following steps to connect cables to the ETHERJACK box
1.

Snap off the ETHERJACK cover.

a. Pry out one side.
b. Lift off cover.
