Filler Panels
The C4 CMTS has two types of filler panels:
Front filler panels — used for any unequipped front module slot
Rear filler panels — used for any unequipped rear PIC slot.
All unused module slots, front and rear, must be equipped with filler panels. Filler panels are required for proper EMC
emission levels and sufficient airflow to properly cool the C4 CMTS system. Failure to cover empty slots reduces the air
flow through the chassis and could result in overheating.
Storing Modules
1.
Retain the packaging in which each module was shipped and follow these guidelines for storing modules to avoid
damage:
2.
Store each module in a separate antistatic bag. Ideally, store the item in its antistatic bag within the protective
packaging or padded box in which the item was shipped.
Installing Modules in the C4 CMTS
CAUTION: Before removing or replacing any C4 CMTS modules, obtain and attach an antistatic grounding wrist or ankle
strap to protect against damage to components resulting from static electricity.
Use extreme care when inserting or removing modules from the C4 CMTS chassis.
Module Installation Overview
Each module is installed in three basic steps:
1.
Use proper ESD precautions before handling modules.
2.
Align and insert module into proper slot. Lock ejector levers before proceeding to the next module: red buttons will
click audibly if module is completely seated in the slot and ejector levers are closed.
