About This Manual
This section describes important information about the design of this document.
Purpose
The purpose of the Juniper Networks G10 CMTS Getting Started manual is to provide
experienced personnel the procedures required to properly install and configure the G10
Cable Modem Termination System (CMTS).
If you do not have experience with the installation and configuration of CMTS equipment in
cable headends, or if you need more details regarding the installation, configuration, or
upgrading of the G10 CMTS, then it is recommended that you follow the procedures
provided in the companion manual Juniper Networks G10 CMTS Installation and Configuration
for more detailed information.
Additional instructions and details regarding the subsequent and on-going operation of the
CMTS can be found in the documents listed in “G10 CMTS Document Set” on page xi.
Organization
Juniper Networks G10 CMTS Getting Started is organized as follows:
Chapter 1, “G10 CMTS Hardware Overview” – Provides a hardware overview of the G10
Chapter 2, “G10 CMTS Installation” – Provides the procedures that must be followed to
Chapter 3, “G10 CMTS Configuration” – Describes the configuration procedure for the
CMTS.

Chapter 1
G10 CMTS Hardware Overview
This chapter provides an overview of the modules and various hardware components of the
G10 Cable Modem Termination System (CMTS), and where they reside within the chassis.
This overview presents material that is specific to the installation and configuration of the
G10 CMTS. For more details and specifications regarding these assemblies, refer to the
Juniper Networks G10 CMTS Functional Description.
Figure 1 on page 2 illustrates a front view of a fully-configured chassis. Figure 2 on page 3
illustrates a front view of a partially-configured chassis in which DOCSIS Modules, a Chassis
Control Module (CCM), a Network Interface Card (NIC) Module, power supplies, air
management modules, and power supply filler panels have been removed. Figure 3 on
page 4 illustrates a rear view of a fully-configured chassis. Figure 4 on page 5 illustrates the
rear view of the partially-configured chassis in which HFC Connector Modules, a CCM Access
Module, a NIC Access Module, and air management panels have been removed. Figure 5 on
page 6 provides a top view of the chassis midplane showing the slot enumeration and
location of each module.
All of the features of the chassis that are cited in these figures will be referenced in one or
more procedures described in this document.
