GainMaker 4-Port Node RF Split 
Upgrade Application Note 

As cable operators experience an exponential rise in the requirements for more 
reverse path bandwidth due to the popularity of advanced, on-demand services 
from an increasing number of subscribers, operators need an upgrade path for 
deployed equipment to overcome this operational challenge. 

 

This application note describes the RF split upgrade procedure for GainMaker® 
4-Port Node. 

You will note that the final instruction in the split change process calls for the 
verification of forward and reverse signal for each port. This verification is 
included to ensure that all component replacements with respect to the split 
upgrade were performed correctly and to ensure that all replacement components 
perform as specified. Making this type of significant product change in the field 
rather than in a test environment would likely cause additional network 
downtime as troubleshooting any sort of issue associated with the upgrade could 
be quite time consuming. 

While our products would generally perform acceptably without this verification, 
we recommend this extra step to ensure that our products meet customer 
expectations immediately upon placement into service. 

Should you need assistance with your upgrade, contact Cisco for support. 

 

    WARNING: 

Avoid electric shock. Opening or removing this equipment cover may expose 
you to dangerous voltages. RF split upgrades should only be conducted on 
products that have been removed from the cable system, not on products 
actively in service. 

 

Only appropriately qualified and skilled service personnel should attempt to 
install, operate, maintain, and service this product.
