Juniper Networks G10 CMTS manual Through the Chassis Control Module

Chassis Control Module

•Functional Characteristics

•
•	The Chassis Control Module contains a 6 U (267 mm) x 340 mm card with a 4 HP (20 mm),
•	single-wide front panel. The module installs from the front of the chassis and is
•	hot-swappable. A Chassis Control Module must be installed in slot 6 or slot 7. These slots and
•	the Chassis Control Module are keyed so no other module can be installed in slot 6, and the
•	Chassis Control Module cannot be installed in any other slots.
•
•	The Chassis Control Module is the single access point to the G10 CMTS for a command-line
•	interface or SNMP management application from a remote location. The Fast Ethernet port
•	Eth0 is used for this purpose. For connecting to the Chassis Control Module locally, use the
•	Eth0 port or the RS-232 COM port on the front panel. All DOCSIS Modules can be managed
•	through the Chassis Control Module.
•
•	The primary functions of the Chassis Control Module are as follows:
•
•	! Store and report configuration and alarm status on DOCSIS Modules and itself.
•
•	! Supply software images to all DOCSIS Modules.
•
•	! Serve as the SNMP agent for the CMTS.
•
•	! Provide the command-line interface.
•
•	! Run the CMTS’s Routing Engine.
•
•	! Support the subscriber account management (SAM) interface.
•
•	! Monitor the state of power supply and fan modules (see “Cooling and Fans” on page 29).
•
•	The Chassis Control Module contains a 500 MHz, Pentium III processor, 512 MB of RAM, and
•	256 MB CompactFlash, all delivering 1,300 MIPS of performance.
