EM4513-MIB

Description: MIB for the EM4513 environmental monitor providing temperature, humidity, and contact sensor management via SNMP.

EM4513-MIB is a vendor MIB (registered under the Accton/cheetahSwitchMgt enterprise branch) for the EM4513 environmental monitoring appliance, a device dedicated to sensing rack or room conditions. It exposes environmental sensor data such as temperature, humidity, and dry-contact/digital input readings rather than networking or interface statistics. Its primary purpose is hardware status monitoring: tracking whether ambient temperature and humidity remain within safe operating thresholds and whether connected contact sensors (e.g., door or water-leak detectors) have tripped, so operations staff can catch environmental faults before they damage co-located equipment. As an enterprise-specific module nested under a switch-management OID tree, it has no formal dependency on standard IETF environmental MIBs. It is typically deployed in server rooms, wiring closets, or equipment cabinets where the EM4513 unit is installed alongside networking gear to provide independent environmental alarms, and administrators can download the EM4513-MIB file directly to load it into their MIB browser.

An administrator would poll the EM4513's sensor objects under the em4513MIB branch to retrieve current temperature and humidity readings and the state of any attached contact inputs, watching for a value crossing a configured high-temperature or high-humidity threshold that signals a cooling failure. A contact sensor reading change (e.g., open-to-closed) would flag a physical event such as a cabinet door being opened or a leak detector triggering. Because the module_desc for this MIB was not available, the exact object names beyond the enterprise/registration branch (private, enterprises, accton, snmpMgt, cheetahSwitchMgt, em4513MIB) could not be confirmed from the source, so specific sensor object names are inferred from the product's known purpose.
