This NAP explains the following work items:
 Extraction of Mounted Circuit Cards
 Mounting of Circuit Cards
 Setting of Switch Positions on Circuit Cards
 Installation of CPR
1. PRECAUTIONS
1.1 Protection Against Static Electricity
When setting switches on circuit cards, use a Portable Field Service Grounding Kit to prevent damage to static-
sensitive components.
Example:    3M Model 8012, consists of:
2 × 2 VELOSTAT 
® Wo r k  M a t
 15 ft. Ground Cord
 CHARGE-GUARD
 ® Wrist Strap with alligator clip
Before handling any circuit cards, first spread out the work mat, then connect the ground cord to the frame or
other ground source.
If a CHARGE-GUARD wrist strap is to be used, connect the wrist strap to the frame or other ground using the
provided cable.
1.2 Handling Circuit Cards
Whenever possible, do not handle circuit cards with bare hands.
The only portion of the card that can be touched is its edge. Do not touch the surface or the mounted components.
Doing so may damage the card.
Handle circuit cards with care. Never bang or drop them.
1.3 Mounting or Removing Circuit Cards When the System Is in Operation
Never mount or remove a circuit card without first setting its MBR and/or MB switch to the UP position.

Remove the Card Stopper Referring to Figure 009-1, remove the card stopper from 
the module.
Extract Circuit Cards Referring to Figure 009-2, pull the card puller tabs in the 
direction indicated by the arrow. The card will release 
from the connector and can then be removed.
Pull the card out about 50 mm (2 inches) from the edge 
of the module so that it does not contact the backplane 
connector.

START
Unpacking the Circuit Cards Unpack each circuit card and remove it from its 
polyethylene bag.
Clean the connector portion of the 
Circuit CardsWipe the connector portion clean using a soft cloth 
moistened with pure trichloroethylene or methanol 
(medical alcohol). Make sure that no lint or dust 
remains on the connector after cleaning.
Circuit cards which are already mounted should be 
extracted and cleaned as per the above instructions.
Confirm the mounting positions of 
the Circuit CardsConfirm the mounting position of each circuit card by 
referring to the Module Face Layout.
Confirm that the color code of the card puller tab 
coincides with that of the card mounting slot.
Confirm the Slot No. on the Module. Slot numbers are 
indicated at the bottom of each module, and range from 
00 to 23.
Insert the cards into the Module Partially insert the circuit card into the module, making 
sure that it is correctly aligned at the top and bottom. 
The card should extend about two inches from the 
module, and must not contact the backplane connector 
(see Figure 009-3).

the module.
Place the extracted card onto the anti-static sheet.
Perform switch setting Set the required switches according to the Switch 
Setting Sheets in the Circuit Card Manual.
Mounting of Circuit Cards After the switches have been set, partially insert the 
card in the module. The card should extend about 50 
mm (2 inches) from the module, and must not contact 
the backplane connector. Refer to Figure 009-3.

5. INSTALLATION OF CPR
This section explains the procedure to install the CPR into the LPM of each Local Node (LN) and ISW. Perform
the following for all the CPR (CPR0/1) of each LN and ISW.
1. Using the Phillips Screwdriver, remove the four + eight screws. Then, detach the front panel and top cover
from the CPR. (Refer to Figure 009-4.)

2. Depending on the system configuration, insert the ISAGT (PZ-GT13/PZ-GT20) and LANI (PZ-PC19)
cards into the following slots of the CPR (refer to Figure 009-5):
ISAGT (PZ-GT13)→slot 6 (ISA) (Fixed)
ISAGT (PZ-GT20)→slot 5 (ISA) (When the LN has 3 or 4 IMGs) 
Note
LANI →Slot 0 (PCI) (For Fusion link)
LANI →Slot 1 (PCI) (When connecting MAT via 10-BASE T and PCI buses)
LANI →Slot 3 (PCI) (When LANI for Fusion link is in dual configuration)
Note:This card is mounted in LN only.
