Circuit Card Installation and Testing
Precautions To avoid personal injury and equipment damage, review the following
guidelines before handling Meridian 1 equipment.
To avoid damage to circuit cards from static discharge, wear a properly
connected antistatic wrist strap when you work on Meridian 1 equipment. If
a wrist strap is not available, regularly touch one of the bare metal strips in a
module to discharge static. Figure 1 shows the recommended connection
points for the wrist strap and the bare metal strips you should touch.

WARNING
Module covers are not hinged; do not let go of the covers. Lift covers
away from the module and set them out of your work area.
WARNING
Circuit cards may contain a lithium battery. There is a danger of
explosion if the battery is incorrectly replaced. Do not replace
components on any circuit card; you must replace the entire card.
Dispose of circuit cards according to the manufacturer’s instructions.

Handle circuit cards as follows:
• Unpack or handle cards away from electric motors, transformers, or
similar machinery.
• Handle cards by the edges only. Do not touch the contacts or
components.
• Set cards on a protective antistatic bag. If an antistatic bag is not
available, hand-hold the card, or set it in a card cage unseated from the
connectors.
• Store cards in protective packing. Do not stack cards on top of each other
unless they are packaged.
• Keep cards installed in the system as much as possible to avoid dirty
contacts and unnecessary wear.
• Store cards in a cool, dry, dust-free area.

Circuit Card Installation and Testing
During repair and maintenance procedures do the following:
• Turn off the circuit breaker or switch for a module power supply before
the power supply is removed or inserted.
• In AC-powered systems, capacitors in the power supply must discharge.
Wait five full minutes between turning off the circuit breaker and
removing the power supply from the module.
• Software disable cards, if applicable, before they are removed or
inserted.
• Hardware disable cards, whenever there is an enable/disable switch,
before they are removed or inserted.
• Return defective or heavily contaminated cards to a repair center. Do not
try to repair or clean them.
Installing a circuit card
This procedure provides detailed installation instructions for Meridian 1
circuit cards.
Procedure 1
Installation
1Open the protective carton and remove the circuit card from the
antistatic bag. Return the antistatic bag to the carton and store it for
future use.
2Inspect the card components, faceplate, locking devices, and
connectors for damage. If damaged, tag the card with a description of
the problem and package it for return to a repair center.
3Refer to the work order to determine the module and slot location for
the card.
4If there is an enable/disable (Enb/Dis)switch on the faceplate, set it to
Dis.
WARNING
To avoid personal injury and equipment damage, read all of the
guidelines in “Circuit Card Installation” on page 10 before you begin
installation and follow all guidelines throughout the procedure.

Page 16 of 74 Circuit card installation
553-3001-211 Standard 17.00 April 2000
5If there are optionswitches or jumpers on the card, set them according
to the work order (see “Option settings” on page 31).
6Squeeze the ends of the locking devices on the card and pull the tabs
away from the latch posts and faceplate (see Figure 2).
CAUTION
Incorrectly set switches on common equipment circuit cards may
cause a system failure.

7Insert the card into the card aligning guides in the card cage. Gently
push the card into the slot until you feel resistance. The tip of the
locking device must be behind the edge of the card cage (see
Figure 2).
8Lock the card into position by simultaneously pushing the ends of the
locking devices against the faceplate.
Note:
When IPE cards are installed, the red LED on the faceplate
remains lit for two to five seconds as a self-test runs. If the self-test
completes successfully, the LED flashes three times and remains lit
until the cardis configured andenabledin software,then the LED goes
out.If theLED does not follow the pattern described or operates in any
other manner (such as continually flashing or remaining weakly lit),
replace the card.
9If there is an enable/disable switch, set it to Enb.
Note:
Do not enable the switch on an NT8D04 Superloop Network
Card or QPC414 Network Card until network loop cables are installed.
10 If you are adding a voice, conference, ortone and digit loop, press the
manual initialize (Man Int) button on the NT5D03 or the NT5D10 Call
Processor (CP) if the card is associated with the active CP:
Note:
An initialization causes a momentary interruption in call
processing.
11 Ifyou areinstallingthecard inaworking system, refer tothe work order
and the
X11 Administration (553-3001-311) to add the required office
data to the system memory.
12 Go to the appropriate test procedure in “Acceptance tests”on page 19.
