Replacing the Dial Shelf Components

Figure3-10 Using the Ejector Levers
Step4 Seat the card in the backplane by pushing the card firmly until the ejector levers fold in
toward the trunk card front panel and the front panel is flush with the chassis frame.
Caution Always use the ejector levers when disengaging or seating trunk cards, modem card s, or
dial shelf controller cards in the dial shelf. Failure to do so can cause erroneous syste m error
messages indicating a card failure. Howev er, do not use the eject or lev ers to lift or support the weight
of the cards.
Step5 Using a No. 2 Phillips screwdriver, tighten the panel fasteners on the top and bottom of
the card front panel. This prevents the card from becoming partially dislodged from the
backplane and ensures proper EMI shielding.
Caution Always tighten the panel fasteners on trunk cards, modem cards, and dial shelf controller
cards. These fasteners prevent accidental removal a nd provide proper grounding for the system.
Step6 Repeat Step3 through Step 5 for all remaining cards you want to install.
Caution To avoid erroneous f ailure m essag es, remo v e o r insert onl y on e trunk card a t a time. Als o,
after inserting or removing a trunk card, allow at least 15sec. before removing or inserting another
trunk card so that the system can reinitialize and note the current configuration of all interfaces.
Step7 Install a blank filler card (DS58-BLANK=) in all empty card slots to keep the chassis
dust-free and to maintain proper airflow.
Caution To prevent the overheating of internal components, always install blank fille r cards in
empty slots to maintain the proper flow of cooling air across the cards.
