Replacement Procedures
To disconnect the feature cards and dial-shelf controller cards from the backplane, follow these steps:
Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 2 Disconnect incoming CE1/CT1 trunk line cables and secure them out of the way using cable ties, if
necessary. On the dial-shelf controller card, disconnect the dial-shelf interconnect cable and the
10BaseT connection, if applicable.
Warning
Before opening the chassis, disconnect the telephone network cables to avoid contact
with telephone-network voltages.
Step 3 Using a number 2 Phillips screwdriver, loosen the panel fasteners at the top and bottom of the card front
panel.
Step 4 Pull either the upper or lower ejector lever away from the card front panel to disengage the card from
the backplane connector. (See Figure 5-28.)
