Environmental Monitoring Probe (EMP) Installation and Connection Quick Start
DANGER:
Electrical current from power, telephone, and communication cables is hazardous. Do not connect or
disconnect any cables or perform installation, maintenance, or reconfiguration of this product during an electrical
storm.
DANGER:
When possible, use one hand only to connect or disconnect signal cables.
DANGER:
Never turn on any equipment when there is evidence of fire, water, or structural damage.
DANGER:
Disconnect the attached power cords, telecommunications systems, networks, and modems before you
open the device covers, unless instructed otherwise in the installation and configuration procedures.

Installation and Connection Quick Start
The optional environmental monitoring probe (EMP) is a connectivity device that enables you to collect temperature and
humidity readings in the rack environment and monitor the environmental data remotely. You can also collect and retrieve the
status of two contact devices.
You can monitor readings locally using the onboard LCD menu display, or remotely using a Telnet connection or a standard
Web browser. This provides greater power management control and flexible monitoring options.
The EMP device is delivered with a screw, Velcro fasteners, tie wraps, and a connection cable. You can install the device
anywhere on the rack. To attach the EMP, use either the Velcro fasteners or mount the EMP on the supplied screw. The EMP
also has a universal slot on the back for mounting easily on a screw and in any direction.
For detailed information about using the EMP, refer to the Eaton Advanced Enclosure Power Distribution Unit (ePDU) User’s
Guide. Access the User’s Guide at http://www.ePDU.com/countries.php.
Features
The environmental monitoring probe has the following features:
S
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.
S
The EMP monitors temperature and humidity information of any environment that you want to protect your critical
equipment. The EMP measures temperatures from 0°C to 70°C with an accuracy of ±2°C.
S
The EMP measures relative humidity from 10% to 90% with an accuracy of ±5%.
S
It can be located away from the ePDU with a CAT5 network cable up to 20 m (65.6 ft) long.
S
The EMP monitors the status of the two user-provided contact devices.
S
Temperature, humidity, and contact closure status can be displayed through a Web browser, a Serial interface, or an
onboard LCD interface.
S
User-selectable alarm thresholds enable you to define acceptable temperature or humidity limits.
S
E-mail notification through Simple Mail Transfer Protocol (SMTP), using e-mail client software when acceptable alarm
limits are exceeded or contact status changes.
S
Changes in external contact status are logged in the ePDU event history log.
S
When temperature and humidity values exceed user-selectable limits, the event is logged in the ePDU event history log.
