CAUTION: Do not expose the interface card or the SDM-9220/9230 unit to a
magnetic field or electrostatic charge at any time. Damage to their components
could result. Use ESD procedure at all times.
7. Hold the interface card so that the printing on the faceplate is right side up, and slide
it into the slot:
CAUTION: Do not force the interface card into the slot. If the interface card is
properly aligned, it should slide easily all the way in along the side rails
provided inside the unit.
8. Press the interface card firmly into place to ensure that it engages securely into the
connector at the rear (on the main board of the unit).
9. Screw the faceplate of the interface card onto the chassis wall by tightening the 2
captive screws.
NOTE: Torque on the faceplate screws should be no more than 6 in-lbs.
CAUTION: Be careful to insert interface cards fully into the unit, and ensure that
all screws are properly tightened. If an interface card is not correctly installed,
proper contact may not be made. This could result in a continuous reset of the
unit, or the unit could boot but the Signaling Engine crash shortly afterward.
