Station Control Before Removing the Old Station Control Module
A new SCM contains settings in a codeplug (EEPROM). Those
settings can be configured, using the RSS, after the module has been
installed.
If the old SCM is capable of communicating with the RSS, the old
codeplug can be read from the SCM and saved to disk to be
programmed into the new SCM. This is described in the Setup and
Connections section of this manual, and in the RSS User’s Guide
(68P81085E35).
If the old SCM is incapable of communicating with the RSS, an
archival codeplug (one saved on disk) can be used to program the
new SCM. If an archival codeplug is unavailable, the new codeplug
will have to be manually configured after installation.
Physical Replacement of
the Station Control
Module
1. Turn off the station’s power by unplugging the AC and DC
power cords from the top panel.
2. Remove the 8 Phillips screws from the edges of the station’s top
panel and lift the chassis out of the case.
3. Remove the cover plate on the left end of the front of the station
by removing two Torx screws from the front of the plate.
Remove the four Phillips screws from the side and bottom
edges of the plate.
4. Pull out the old Control Module by gripping behind its DB-9,
RJ-11, and RJ-45 connectors, distributing pressure equally
among the connectors.
5. Insert the new module. Make sure it is in the cardguides; push it
firmly into the chassis until it seats into the card-edge
connectors on the backplane. (Do not slam the board against the
backplane or push any harder than necessary to seat the
connectors.)
6. If desired, power up the station while it is still out of the case to
make sure the module is securely in place. If the LEDs do not
light, are dim, or flash rapidly, one or more modules are not
seated properly. Unplug the station before continuing to the
next step.
7. Reassemble the station by reversing steps 2 and 3.
After Installing the New
Station Control Module
1. If the codeplug from the old SCM was saved to disk, or if an
archival codeplug exists on disk, it should be programmed into
the new SCM.
