New Hardware Installation Procedures
The installation of new hardware features onto the SCON-20L/22L can be very
similar to the replacement of existing hardware with a couple of notable exceptions.
First you will be removing and discarding existing plates and brackets, and
substituting feature boards in their place. Secondly, you will need to know where
to place the new board, since the existing 20L/22L does not already have one
installed. Finally, you may need to inform the software, through configuration,
that the new hardware has been installed.

Second CDA Installation (SCON-22L Only)
1. Follow the procedures for removing the covers from the SCON-22L.
2. Locate the metal plate attached to rear bracket, covering 4 openings at the rear
of the 22L. This metal plate is located next to the J2 location as shown in the
Physical Slot Identification drawing (Figure 3-1)
3. Remove the two screws securing the metal plate to the rear bracket, and discard
the bracket.
4. Use the two screws removed in step 3 to secure the CDA board into place,
ensuring that the CDA is plugged into the J2 connector.
5. Reassemble the covers.
6. Using the SCON-20L/22L/25L Configuration Manual as a guide, verify that
your configuration includes 32 coax ports (it may be configured for 16 coax
ports only). Reconfigure as needed.
