7-2 CHP Max™ Headend Optics Platform Chassis, Controllers and Power Supplies Rev D
Security
The SMM-2 provides access to the Command Line Interface (CLI) via Telnet with a user ID /
password authentication mechanism supporting administrator and operator groups. It
supports configurable SNMP community strings for Read-Only and Read-Write Access.
Topology
The SMM-2 provides inventory information for the modules, power supplies and fans within
a chassis via CLI and/or SNMP. The topology information includes shelf/slot number, module
type, name, status, etc.
Faults
The SMM-2 provides alarms on the modules, power supplies and fans and supports discrete
and threshold alarms. The alarms can be enabled/disabled from SNMP MIBs and their
thresholds can be set by the user using SNMP. The SMM-2 can also send SNMP Traps to
management applications (up to 16 destinations).
Configuration
The SMM-2 provides configuration MIBs for management of the CHP chassis and supported
application modules.
Software Upgrade
The SMM-2 supports upgrades of the SMM-2 and supported application modules.
MIB Support
The SMM-2 supports the following Management Information Bases (MIBs) (refer to
Appendix A for more information):
■ MIB-2 System Group – RFC1213-MIB
■ entPhysicalTable – ENTITY-MIB (inventory)
■ currentAlarmTable – SCTE-HMS-PROPERTY MIB (faults - active alarms)
■ discretePropertyTable – SCTE-HMS-PROPERTY MIB (alarm enables/disables)
■ chpShelf, chpSlot, configuration and ststus tables – CHPMAX5000-MIB
■ heCommon – SCTE-HMS-HE-COMMON-MIB
■ hePowerSupply – SCTE-HMS-HE-POWER-SUPPLY-MIB
■ heFanUnitTable and heFanStatusTable – SCTE-HMS-FAN MIB
Local Monitoring
A computer is used to monitor a single CHP Max5000 chassis through a direct USB
connection to the SMM-2 controller module or direct connection to the backplane Ethernet
port. The controller module sends management signals through the chassis backplane to the
other modules installed in the chassis, and status information from the modules travels back
