One SCM in slot 19
One RCM in slot 17
Slot Numbering Scheme
The eight slots from top to bottom are numbered and populated as follows:
Slot 15 16D or XD CAM
Slot 14 12U or 16D or XD CAM
Slot 13 12U or 16D or XD CAM
Slot 12 12U or 16D or XD CAM
Slot 11 12U or 16D or XD CAM
Slot 10 12U CAM
Slot 19 SCM
Slot 17 RCM
The slot numbering scheme makes the C4c CMTS compatible with C4 CMTS software. Without this numbering scheme the
software would return provisioning errors for cards used in the wrong slots.
The CAMs, RCM, SCM, power modules, and Fan Tray Module plus filter are hot-swappable and field-replaceable units.
Limited Support for the 2Dx12U CAM in the C4c CMTS
The C4c CMTS has limited support for the 2Dx12U CAM:
Up to a maximum of six (6) 2Dx12U CAMs per C4c chassis
If 2Dx12Us are used, then no 16D, XD or 12U CAMs can be used in the same chassis
The 2Dx12U can be used in any CAM slot (i.e., slots 10-15)
The 2Dx12U CAMs can be used for voice or data
The 2Dx12U CAM does not support channel bonding.
Note: The C4c CMTS does not support CAM sparing.
