Installing the Network Interface Cards
This chapter shows how to install a Network Interface Card into the DECNIS
600 when it is powered down.
Some DECNIS 600 configurations are supplied with the Network Interface
Cards already installed. If your system arrives with all cards installed, follow
the procedures in Sections 3.7 to 3.10 only.
If you want to install a Network Interface Card in a running system, refer to
Chapter 5.

3.1 Tasks
Complete the procedures in Sections 3.2 to 3.9 to:
1. Prepare to install the Network Interface Card
2. Check that the system is switched off
3. Attach the static protection equipment
4. Remove the slot cover
5. Install the Network Interface Card
6. Install the distribution panel (if included as part of the Network Interface
Card kit)
7. Attach the communications cables
8. Enable the Network Interface Card

Installing the Network Interface Cards 3–1

3.2 Preparation
Before you begin the installation procedure, check the contents of the Network
Interface Card kit. The Cabling Instructions and Specifications card for the
Network Interface Card lists the contents of the kit.
Note
Do not remove the Network Interface Card from its antistatic
packaging until you have completed the procedures in Section 3.4.
The packaging protects the card from damage caused by static
discharge.

When you unpack the kit, keep all of the packaging in case you need to remove
and replace the Network Interface Card.
If any part of the kit is missing or damaged, contact your local Digital
representative.

3.2.1 Tools
You will need the following tools for the Network Interface Card installation:
•

Antistatic kit that includes an antistatic wrist strap and antistatic mat

•

A 3 mm ( 81 in) flat blade screwdriver

3.2.2 Network Interface Card Position
The Network Interface Cards can be installed in slots 3 to 9 in any order.
However, each time that a Network Interface Card is moved to a different slot,
the software configuration utilities must be run (see the software configuration
documentation for more information). For this reason, Digital recommends
that Network Interface Cards remain in the same slot wherever possible.
Management of the DECNIS 600 may be made easier if Network Interface
Cards of the same type are grouped together. Management of several network
systems may also be made easier if the organization of line configurations are
consistent. For example, LAN cards could be installed from slot 9 towards slot
3, and WAN cards from slot 3 towards slot 9.

4.5 Monitor the System Displays and LEDs
On power up, the DECNIS 600 automatically tests each module and then tests
the operation of the installed system:
1. Module self-test
The DECNIS 600 activates a module self-test on each card that is installed
and enabled. The module self-test checks the card for faults.
2. System self-test
When each card has completed its module self-test, the DECNIS 600 runs
a system self-test. This test checks that each card can interact with the
rest of the system. It then runs a diagnostic check to test the operation of
the whole system.

4–4 Testing the Installed System

The progress of these tests is shown on the system displays located on the
processor card and on the card LEDs:

LKG–5652–91I

The memory card is not tested (no LEDs lit) until the processor card has
successfully completed its module self-test.
When the processor card has passed module self-test, its READY LED
remains lit and the memory card starts module self-test. The memory
card’s READY LED flashes (one flash per second) to indicate that testing is
in progress.

4–6 Testing the Installed System

2. As soon as the memory card has passed module self-test and its READY
LED remains lit, the Network Interface Cards interact with it as part of
their module self-test. At this point, their READY LEDs flicker (8 flashes
per second):

Part III
Problem Solving

Part III contains information that you need for solving DECNIS 600 hardware
problems:
•

Chapter 9 describes how to identify a problem.

•

Chapter 10 describes how to locate a faulty component in the system.

•

Chapter 11 describes how to replace the faulty component.

9
Identifying the Problem
Problem solving information for the DECNIS 600 is divided into hardware
problems, Network Interface Card problems, software problems, and event
messages:
•

This part of the manual describes how to identify and solve DECNIS 600
hardware problems.

•

The Problem Solving card for each Network Interface Card shows how to
isolate Network Interface Card specific faults and check communication
lines.

•

The DEC Network Integration Server Problem Solving manual describes
how to isolate and solve software problems.

•

DEC Network Integration Server Event Messages is an online text file that
lists the event messages generated by the DECNIS 600 and tells you what
to do when an event is generated. Events can indicate faults with the
hardware, software, and the Network Interface Cards.

If you are not sure whether the problem can be isolated to, for example, the
DECNIS 600 or a Network Interface Card, start with the procedures in this
manual. The procedures will help you to determine where the problem lies.
Where problems overlap, you may be referred to other problem solving
documentation. For example, for problems that can usually be isolated
to the software, this manual refers you to the software problem solving
documentation before it suggests ways that you can check the hardware.

Identifying the Problem 9–1

9.1 Preparation
Make sure that the following information and equipment is available:
•

Configuration Information
For some procedures, you will need the following information:
Load host node name(s)
DECNIS 600 Ethernet address(es)
Slot numbers for Network Interface Cards
Details of the link associated with each slot
This information is included on the DEC Network Integration Server 600
Configuration Card and the configuration cards for the Network Interface
Cards.

•

Loopback Connectors
For some tests you will need a loopback connector. Each Network Interface
Card kit includes a loopback connector for the card and its cables. For
more information, refer to the Cabling Instructions and Specifications card
for the Network Interface Card.

•

Static Protection Equipment
For some problem solving procedures you will need an antistatic kit that
includes an antistatic wrist strap and antistatic mat. Section 3.4 shows
how to attach the static protection equipment.

9.2 How to Identify the Problem
The amount of information that you have about your problem determines how
you identify the problem and use this part of the manual:
•

If the software is loaded, or was loaded when the problem occurred, check
event messages. The DEC Network Integration Server Event Messages text
file describes events logged by the DECNIS 600. The event message may
indicate a fault with the DECNIS 600, for example, an overtemperature
problem. You can use this information to refer to the relevant section in
Chapter 10.

9–2 Identifying the Problem

•

If the DECNIS 600 reboots, you can use NCL (Network Control Language)
to find out more information about the problem. Log on to a host system,
start NCL, and enter the following command:
NCL> SHOW NODE server HARDWARE LAST REBOOT REASON

where server is the name for the DECNIS 600.
The displayed information gives the reason for the last reboot. If the
information indicates a hardware problem, refer to the relevant section in
Chapter 10. For example, if the information indicates an overtemperature
problem, follow the procedures in Section 10.3.
•

If the DECNIS 600 is powered up and the LEDs or displays indicate a
fault, refer to Sections 9.2.1 to 9.2.3 to identify the problem and find out
what to do next.

If there are no LEDs lit on the DECNIS 600, or if you are not sure where the
problem lies, power up the system and start at Section 9.2.1.

fault, install the Network Interface Card in another slot (see Chapter 3).
C. Power up the unit and monitor the system displays on the processor card:
•

If the system self-test (upper) display shows the value 2, check the
system operation (lower) display:
If the displayed value matches the slot number for the Network
Interface Card, for example, if the display shows the value 5 and
the Network Interface Card is installed in slot 5, the fault can be
isolated to the Network Interface Card.
If another value is displayed on the system operation display, it
indicates that the fault is associated with other components in the
unit. The Network Interface Card is not faulty.
Follow the corresponding path on the flowchart.

•

If the system self-test (upper) display shows another value (not 2), it
could indicate an intermittent problem. Contact Digital Services.

the DECNIS 600 and the point of connection to any particular digital circuit,
then all the other apparatus must conform as follows:
1. The overall transmission characteristics of all the other apparatus shall
be such as to introduce no material effect upon the electrical conditions
presented to one another by the apparatus and the particular digital
circuit.
2. All the other apparatus shall comprise only:
•

Apparatus approved (such apparatus may be subject to limitations on
its use) for the purpose of connection between the apparatus and a
particular digital circuit.

•

†Voltage used or generated by other parts of the DECNIS 600 system.
‡Creepage distance where the DECNIS 600 is subject to conductive pollution or dry nonconductive
pollution which could become conductive due to condensation.

These distances can be checked by measuring between the adjacent parts as
shown in Figure C–1. Clearance distance is shown by the identifier x, which is
the shortest distance in air between two points. Creepage distance is shown by
the identifier y, which is the path taken around the system between the same
two points.
If you are in doubt, consult a competent telecommunications safety engineer for
advice. Failure to install a Network Interface Card in accordance with these
instructions will invalidate the BABT approval.
