Downstream CMTS Parameter Characterization
Verification of Shipping Cartons
Prior to beginning the installation of the G10 CMTS, you should verify that the contents of the
shipping cartons are identical to the contents listed on the packing lists. In addition, you
should carefully inspect the shipped contents to ensure that they are not damaged in any
manner. If any contents are missing or damaged, report this to customer support.
To verify the contents of the shipping cartons match the packing list, use the following
procedure:
1. Carefully open the shipping cartons. Pay attention to any instructions printed on each
shipping carton.
2. Remove all the contents of the shipping cartons. When lifting heavy contents, be sure to
follow the safety precautions listed in “Safety Precautions” on page 68.
3. Verify that the contents of the shipping cartons are identical to the contents listed on the
packing lists.
4. Verify that the correct number of power supplies are installed in the G10 CMTS chassis.
5. Open all accessory kits that are included in the shipment. Verify that the contents are
identical to the contents listed on the accessory kit packing lists.
6. Install the power supply faceplate included in the shipment by aligning its four ball studs
with the four power supply faceplate clips and pressing the faceplate towards the chassis
until it snaps into place. If you will install additional power supplies, this step can be
deferred.
7. Install the air intake faceplate included in the shipment by aligning its four ball studs
with the four air intake faceplate clips and pressing the faceplate towards the chassis
until it snaps into place.
