Common Control Module

CCM Installation

With the exception of the power supply modules, all plug-in modules have an insertion and
extraction tab on the bottom of the front panel.
1. To install a plug-in module, insert the module into its slot with the GDC logo on top, then slide
it in until it makes contact.
2. Pull down the insertion/extraction tab and firmly push the module in until it seats in the rear
connectors.
3. To remove a plug-in module, pull down the insertion/extraction tab to unseat the module, then
pull on the tab.

Installation Restrictions

Any module may be installed in any slot, with the following restrictions:
Assignment of modules to slots must be that of the configuration on the TMS Controller or
OCM-1000 Point-to-Point Controller. For example, the CCM should be placed in the first slot
following the power supply module(s), if that is what the configuration shows.
Redundant or diverse pairs of modules, when used, must be in adjacent paired slots, in the same
shelf, for example, 1-2. Rear panel Zone 1 (top) and Zone 3 (bottom) connector panels must
meet the module requirements. The X1 jumper must be in the correct position.
Earlier versions of the CCM (CCM-6 and CCM-7) can operate in the same network with the
CCM-10. However, in OCM shelves configured for CCM redundancy, both CCMs of the
redundant pair must be the same type.
For maximum system reliability, we recommend that a module be removed from the currently
active TMS configuration before it is extracted from its slot.
