What Is OMNI-gx2Em870-MIB?

This MIB manages the Cisco (originally Scientific-Atlanta) GX2 EM870 870 MHz expansion module, a plug-in card used in GX2-series hybrid fiber-coax (HFC) optical nodes to extend RF bandwidth handling in cable television/broadband access networks. No sample objects were provided in this batch, but expansion-module MIBs in this OMNI family typically expose module presence/identity, RF signal level, and operational status objects for the card slot. Its role is hardware status monitoring for the optical node: confirming the EM870 module is present, correctly identified, and operating within expected RF signal parameters, which affects downstream/upstream signal quality delivered to subscribers. It is part of Cisco/Scientific-Atlanta's proprietary GX2 optical node MIB family (OMNI-*) rather than an IETF standard, and is likely referenced alongside sibling node/shelf MIBs for full node management. It is deployed in cable operator HFC networks wherever a GX2 optical node is fitted with an 870 MHz expansion module to support extended-spectrum service. Engineers can download the OMNI-gx2Em870-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2Em870-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 EM870 870 MHz expansion module)

Monitoring Examples

An operator would poll the module's identity and status objects (following the OMNI-gx2 module pattern) to confirm the EM870 card is inserted, recognized, and reporting a healthy operational state in its optical node slot. A module reporting missing or a fault status would indicate a card failure or seating issue requiring a field truck roll. Because no object names were available in this batch, exact object names cannot be confirmed and this description reflects the module's known general purpose within the GX2 product line.

What Can Be Monitored

  • module presence/identity
  • module operational status
  • RF signal level
