The optional environmental monitoring probe (EMP) is a connectivity device that gathers temperature and humidity readings within the rack environment. It allows remote monitoring of environmental data through the onboard LCD screen, a Telnet connection, or a standard web browser. Additionally, it enables the collection and retrieval of status information from two contact devices.
Key Features
When temperature and humidity values exceed user-selectable limits, the event is logged in the ePDU event history log.
The EMP monitors temperature and humidity information of any environment that you want to protect your critical equipment. The EMP measures temperatures from 32°F to 158°F (0°C to 70°C) with an accuracy of ±3.6°F (±2°C).
The EMP measures relative humidity from 10% to 90% with an accuracy of ±5%.
It can be located away from the ePDU with a CAT5 network cable up to 65.6 ft (20 m) long.
The hot-swap feature simplifies installation by enabling you to install the probe safely without turning off power to the ePDU or to the loads that are connected to it.
The EMP monitors the status of the two user-provided contact devices.
Temperature, humidity, and contact closure status can be displayed through a web browser, a serial interface, or an onboard LCD interface.
User-selectable alarm thresholds enable you to define acceptable temperature or humidity limits.
Email notification through Simple Mail Transfer Protocol (SMTP), using email client software when acceptable alarm limits are exceeded or contact status changes.
Changes in external contact status are logged in the ePDU event history log.


The optional Eaton Environmental Monitoring Probe (EMP) Gen 2 is a connectivity device that enables you to collect temperature and humidity readings in rack enclosures and monitor environmental data remotely using Eaton's power monitoring solutions or a standard web browser. Each EMP provides one temperature, one humidity, and two dry-contact status data points. Compatible with UPSs and PDUs, the EMP Gen 2 features a translucent case and integrated LED to positively identify the status of each sensor at a glance while walking the aisles.
