What Is OMNI-gx2RFA1000-MIB?

OMNI-gx2RFA1000-MIB is a vendor MIB for the Cisco/Scientific-Atlanta GX2 RFA1000 RF amplifier module deployed in HFC optical nodes to boost the RF signal within the coax distribution network. It exposes module configuration and status objects such as gain/attenuation settings and amplifier operating state within the GX2 chassis management model. Its main monitoring value is hardware health of the amplifier itself, allowing operators to detect an amplifier module that has failed, dropped offline, or drifted out of its configured gain range, which directly affects downstream signal quality to subscribers. It belongs to the same OMNI-gx2 module family as the laser, RF switch, and attenuator MIBs, sharing a common chassis/slot management approach. It is typically deployed in HFC optical node cabinets as part of a cable operator's outside-plant equipment. Engineers can download the OMNI-gx2RFA1000-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2RFA1000-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • General Instrument OmniStar GX2 HFC headend/optical node (GX2 RFA1000 RF amplifier module)

Monitoring Examples

No sample object names were provided for this module; in practice an operator would poll the amplifier's per-module status and gain-level objects within the GX2 chassis tree. An amplifier module reporting a fault status or an unexpected gain deviation would reveal an RFA1000 hardware problem degrading RF signal levels downstream to subscribers. It is typically monitored alongside sibling OMNI-gx2 module MIBs covering the rest of the same optical node chassis.

What Can Be Monitored

  • amplifier module operational status
  • gain/attenuation level
  • module fault condition
