3.2.3 Removing a DSP Module
► To remove a DSP module:
1.
Open the SDM-9120/9220/9230 chassis casing as described on “Installing the DSP
module” on page 3-3 , heeding the
Caution
note concerning ESD procedure, and the
Warning
to turn the unit off and disconnect the power cord first.
2.
Locate the small metal clips that hold the DSP module into place at each end of the
DSP socket. Push the clips apart with the tips of your fingers. The module will spring
into a more vertical position.
3.
Holding the DSP module by its edge, carefully lift it up and out of its socket.
4.
If you are not installing another DSP, replace the unit’s cover as described in the next
section.
3.2.4 Closing the Chassis Casing
► To close the casing of the SDM-9220/9230 chassis:
1.
Hook the bottom lip of the front of the cover onto the bottom of the SDM-9120/9220/
9230 unit’s front panel, using an upward motion.
NOTE:
If the bottom lip of the cover is fitted properly onto the front of the chassis,
the light pipes for the system status LEDs will slip easily into the holes
provided for them.
2.
Keeping the bottom lip in place on the front panel, rotate the rear of the cover down
over the unit chassis. You may need to push the cover slightly toward the rear to
ensure that it is well seated over the rear panel. See
Figure 3-4 .
Caution
DSP modules must be removed with care. Use ESD procedure at all
times.
Caution
Do not expose the DSP module or the SDM-9120/9220/9230 unit to a
magnetic field or electrostatic charge at any time. Otherwise, damage to
the components may occur. Use ESD procedures at all times.
Caution
Do not turn the unit on unless its cover is properly installed and
secured.
