Chapter 4: Installation Procedures
Insert the Radio and Utility Shelf Cards
See pages 82 to 85 for the location of each card. If the configuration of your
NPM does not use a full complement of cards, some slots will be left empty.
Figure 4.15 shows how to properly insert a card into a shelf.
Figure 4.15 Card Insertion
WARNING: The cards use components that are sensitive to electrostatic
discharges (ESD). Make sure you are wearing an approved and regularly
tested grounded wrist strap connected to the grounding point on the PDP.
When you handle the cards, hold them by their handles or edges. Do not touch
electrical connections, pins, or soldered surfaces.
The pins on the backplane are easily damaged. When inserting cards
(especially the hard disk drives), ensure that the connectors are properly
aligned before applying sufficient pressure to seat the card. Apply equal
pressure to both ejector handles when inserting the card. Failure to do so may
result in the pins or connectors being damaged.
