Chapter 4: Base Station Installation Procedures
Insert the Radio and Utility Shelf Cards
See pages 69 to 72 for the location of each card. If the configuration of your base station does not use
a full complement of cards, some slots will be left empty.
Figure 4.14 shows how to properly insert a card into a shelf.
Figure 4.14 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.
