About this document
This document describes the maintenance of the PCM30 line drawer (PLD).
Procedures are provided for clearing alarms and replacing cards. This docu-
ment is intended for maintenance personnel in an operating company.
When to use this document
Northern Telecom (NT) software releases are referred to as batch change
supplements (BCS) and are identified by a number, for example, BCS29.
This document is written for DMS-100 Family offices that have software
loads of BCS33 and up.
More than one version of this document may exist. The version and issue
are indicated throughout the document, for example, 01.01. The first two
digits increase by one each time the document content is changed to support
new BCS-related developments. For example, the first release of a
document is 01.01, and the next release of the document in a subsequent
BCS is 02.01. The second two digits increase by one each time a document
is revised and rereleased for the same BCS.
To determine which version of this document applies to the BCS in your
office, check the release information in DMS-100 Family Guide to Northern
Telecom Publications, 297-1001-001.

What precautionary messages mean
Danger, warning, and caution messages in this document indicate potential
risks. These messages and their meanings are listed in the following chart.
Message Significance
DANGER Possibility of personal injury
WARNING Possibility of equipment damage
CAUTION Possibility of service interruption or degradation
Examples of the precautionary messages follow.
DANGER
Risk of electrocution
The inverter contains high voltage lines. Do not open the front
panel of the inverter unless fuses F1, F2, and F3 have been
removed first. Until these fuses are removed, the high voltage
lines inside the inverter are active, and you risk being
electrocuted.
WARNING
Damage to backplane connector pins
Use light thumb pressure to align the card with the connectors.
Next, use the levers to seat the card into the connectors. Failure
to align the card first may result in bending of the backplane
connector pins.
CAUTION
Loss of service
Subscriber service is lost if you accidentally remove a card from
the active unit of the peripheral module (PM). Before
continuing, confirm that you are removing the card from the
inactive unit of the PM.
