Description: Manages Carel industrial controller used in Rittal LCP 3311 data center in-row cooling units for temperature and cooling status.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CAREL-RITTAL-LCP-3311-MIB?

CAREL-RITTAL-LCP-3311-MIB is a vendor-specific MIB for the Carel industrial pCO controller used inside Rittal LCP 3311 in-row liquid cooling units deployed in data center racks, accessed via a pCO web card. It exposes almost entirely fault/alarm status objects covering the compressor, pressure system, inverter drive, and general unit health, alongside remote on/off control objects. In monitoring terms this MIB is squarely aimed at hardware fault detection for data center cooling infrastructure -- surfacing conditions like compressor overload, high pressure, inverter/drive faults, compressor envelope violations, startup failures, excessive discharge temperature, and delta-pressure faults, all of which directly indicate the physical health of the cooling unit's refrigeration hardware. It is a self-contained proprietary MIB tied to the Carel pCO web card's SNMP gateway rather than any IETF standard. It would typically be deployed in a data center facilities monitoring system tracking in-row cooling units alongside rack-level temperature and airflow sensors. Engineers can download the CAREL-RITTAL-LCP-3311-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CAREL-RITTAL-LCP-3311-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

Rittal LCP 3311 in-row cooling unit (Carel pCO controller)

Monitoring Examples

An administrator would poll compressorOverloadAlarm, highPressureAlarm, and compressorDeltaPressureAlarm to catch early signs of refrigerant circuit problems in the LCP 3311 unit before a full compressor failure occurs. maxDischargeTemperatureAlarm and inverterAlarm/driveAlarm would be checked together to distinguish a thermal problem from a variable-speed drive electronics fault. If generalAlarm is set, an operator would drill into the more specific alarm objects to identify root cause, and could use resetAllAlarms (with remoteOnOff) to clear faults and cycle the unit after remediation.

What Can Be Monitored

compressor overload status
high pressure alarm
inverter/drive fault status
compressor envelope and startup failure alarms
discharge temperature alarm
delta pressure alarm
general alarm/unit status

How to Use in IPNetwork Monitor

Example using compressorOverloadAlarm OID:

Select a Rittal LCP 3311 in-row cooling unit (Carel pCO controller) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type compressorOverloadAlarm into the Find box to locate it in the OID tree, then select it and click OK. It reports the compressor overload alarm ok (0), alarm (1). On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'ok', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
