About this document
Purpose This book provides information about replacing cards in Nortel Networks
equipment. It is intended for personnel involved in the maintenance of the
Meridian SL-100 SE switch.
This manual applies to offices that have the MSL 15 software release. Unless
the document is revised, it also applies to offices that have software releases
greater than MSL15.
Note: The MSL15 software delivery is part of an on-going evolution. This
book is one of several transitional documents that must be used with the
following DMS-100 counterparts for the full complement of
documentation:
•NA DMS-100 Card Replacement Procedures,
297-8001-547
Disregardthesignalingpoint(SP),TrafficOperationPositionSystem(TOPS).
and SuperNode Data Manager (SDM) information as it does not apply to the
Meridian SL-100 switch.
How to check the version and issue of this document
The version and issue of the document are indicated by numbers, for example,
01.01.
The first two digits indicate the version. The version number increases each
time the document is updated to support a new software release. For example,
the first release of a document is 01.01. In the next software release cycle, the
first release of the same document is 02.01.
The second two digits indicate the issue. The issue number increases each
time the document is revised but rereleased in the same software release cycle.
For example, the second release of a document in the same software release
cycle is 01.02.

What precautionary messages mean
The types of precautionary messages used in Nortel Networks documents
include attention boxes and danger, warning, and caution messages.
An attention box identifies information that is necessary for the proper
performance of a procedure or task or the correct interpretation of information
or data. Danger, warning, and caution messages indicate possible risks.
Examples of the precautionary messages follow.
ATTENTION - Information needed to perform a task
ATTENTION
If the unused DS-3 ports are not deprovisioned before a DS-1/VT
Mapper is installed, the DS-1 traffic will not be carried through the
DS-1/VT Mapper, even though the DS-1/VT Mapper is properly
provisioned.

DANGER - Possibility of personal injury
WARNING - Possibility of equipment damage
CAUTION - Possibility of service interruption or degradation
How commands, parameters, and responses are represented
Commands, parameters, and responses in this document conform to the
following conventions.
Input prompt (>)
An input prompt (>) indicates that the information that follows is a command:
>BSY
Commands and fixed parameters
Commands and fixed parameters that are entered at a MAP terminal are shown
in uppercase letters:
>BSY CTRL
DANGER
Risk of electrocution
Do not open the front panel of the inverter unless fuses F1,
F2, and F3 have been removed. The inverter contains
high-voltage lines. Until the fuses are removed, the
high-voltage lines are active, and you risk being
electrocuted.
WARNING
Damage to the backplane connector pins
Align the card before seating it, to avoid bending the
backplane connector pins. Use light thumb pressure to
align the card with the connectors. Next, use the levers on
the card to seat the card into the connectors.
CAUTION
Possible loss of service
Before continuing, confirm that you are removing the card
from the inactive unit of the peripheral module.
Subscriber service will be lost if you remove a card from
the active unit.

XPM card replacement procedures
Purpose This chapter contains procedures for replacing the NTAX78AA card in
an ISDN digital trunk controller (DTCI) shelf.
For each card replacement task, you will find a procedure containing
the following details:
•explanatory and context-setting information
•summary flowchart
•step-action instructions
Recording card replacement activities
When a card is replaced, the following information should be noted in
office records:
•the serial number of the replaced card
•the date of replacement
•the reason for the replacement
Explanatory and context-setting information
In each procedure, the section titled “Application”identifies the card
PECs (including suffixes) and the shelves or frames to which this
procedure applies. Read this section before you perform the
step-actioninstructions.If the “Application”sectiondoesnotidentifythe
card and shelf you are looking for, go to the “Index”where all card and
shelf combinations included in this book are listed.
The “Common procedures”section lists common procedures that you
may be asked to perform as you follow the step-action instructions. Go
to these common procedures only when directed to do so.
Summary flowchart
The flowchart is a summary of the main actions, decision points, and
possible paths you may take. Do not use the summary flowchart to

16 XPM card replacement procedures
555-4031-547 Standard 12.02 July 2002
perform the procedure. Instead, use it to preview what you will be doing
and to prepare. For example, if you see that the instructions will involve
another office, you will know to advise that office before you begin the
step-action instructions.
Step-action instructions
The step-action instructions tell you how to change a card. Normally,
you perform the steps in order, but you may be directed to return to a
previous step and repeat a sequence. The successful completion of a
step in a sequence may depend on previous steps; therefore always
perform the steps in the order specified.
While following the step-action instructions, you may be sent to the
“Common card replacement procedures”chapter of this book or to
another Nortel Networks technical publication (NTP) toperform a set of
instructions. If this happens, you will be told when to return to the
original instructions, and to which point in those instructions you should
go.
The step-action instructions provide thecommand syntax and machine
output you use or see while performing this procedure. For help on
DMS commands or output, see Commands Reference Manual,
297-1001-822.
