Introduction

Overview

The EC1000 Energy Box solution is the latest evolution of ATEN’s energy

intelligence product line NRGence™. The EC1000 monitors the electrical

current of 4 Energy PDU's, along with room temperature, humidity, and

differential pressure using environmental sensors. The Energy Box provides

instant real-time power management and energy-saving control for data

centers– allowing you to upgrade and maintain your current IT power

resources quickly and cost-effectively.

The EC1000 Energy Box has four RJ-45 ports to connect to four Energy PDUs

and four RJ-11 ports to connect external sensors to monitor environmental

conditions. Each environmental sensor can provide measured readings of

temperature, humidity, and differential pressure from separate areas of a room,

giving you a wide range of monitoring and protection.

The EC1000 features real-time status, system logs, threshold alerts, and event

notification. The Energy Box logs power and environmental conditions

according to customizable minimum/maximum thresholds set for; current,

temperature, humidity, and differential pressure.

The Energy Box allows the power and environmental data to be monitored by

display at the rack or remotely for easy viewing and maintenance. The Energy

Box is a standalone unit with over IP monitoring that is controlled by a built-

in web GUI or ATEN's eco Sensors software.

Remote monitoring offers secure access with 128bits SSL encryption, and

customizable account policies for user management. Remote authentication

supports RADIUS and additional management interfaces including HTTP,

HTTPS, and SNMPv1&v2&v3 (Read, Write, Trap). Event notifications can be

monitored via Syslog/SMTP/SNMP trap and by audible alarm for real-time

local and remote alerting.

The NRGence™ EC1000 Energy Box is the intelligent cost effective solution

to monitor ATEN's Energy PDUs – to ensure safe and effective energy-saving

power management.

Optional Accessories

Sensors

Sensors are optional accessories. You can use the EC1000 Energy Box without

sensors. However, if you want to have complete energy management of your

data center with the full use of the EC1000 Energy Box, you would need to use

eco Sensors software and install 4 sensors for each of the racks to generate

more complete energy-efficient data and charts. Sensors help you maintain a

safe and highly efficient data center by monitoring environmental conditions.

Higher sensor density installations help to generate more accurate and precise

data. Available sensors are show in the table, below:

Sensor Management

Sensors can be managed via the EC1000’s browser based graphical user

interface (GUI) or with NRGence™ eco Sensors software that can be

downloaded from the ATEN website. The download link can be found on the

software CD provided with the EC1000 package.

to screw the rack mounting brackets into the sides near the front of the

brackets with the holes in the rack.
