Specifications
Overview
The GRSE Series Environmental Monitoring Units provide remote environmental monitoring and
alarming capability needed to detect climate conditions in data centers. The GRSE Series
environmental monitoring units are equipped with a built-in web server. Web pages, including
graphs, are generated by the unit to monitor environmental conditions within the cabinet. No
software other than a web browser is required for operation and several data formats are
available. In GRSE Series units, built-in sensors monitor Temperature, Relative Humidity,
Airflow, Light Level and Sound Level. Optional external sensors and network cameras are also
available. The GRSE Series is available in two different versions; the GRSE2X16 and GRSE-B.
The GRSE2X16 and GRSE-B are identical except for the scrolling LCD display and alarm buzzer
features of the GRSE2X16.

Installation
Guidelines
If the Environmental Monitoring Unit is installed in a cabinet the ambient temperature of the
rack should be no greater than 45C.
Install the Environmental Monitoring Unit such that the amount of airflow required for safe
operation of equipment is not compromised.
Mount the Environmental Monitoring Unit so that a hazardous condition is not achieved due
to uneven mechanical loading.

Network Overview
This product comes preconfigured with a default IP address set. Simply connect to the
Environmental Monitoring Unit and access the web page with your browser.
Default IP Address
GRSE Series units have a default IP address for initial setup and access to the unit if the
assigned address is lost or forgotten. Once an IP address is assigned to a unit, the default IP
address is no longer active. To restore the default IP address, press the reset button located
below the network connector and hold for approximately 20 seconds. The idle and activity
lights on the network connector will both light up when the IP address has been reset. The
reset button is accessed through the white, circular hole located below the Ethernet jack.
Note: Pressing the reset button under the network connector will restore the default IP address
and will also clear all password settings.
The Configuration page allows you to assign the network properties or use DHCP to connect to
your network. Access to the unit requires the IP address to be known, so use of a Static IP or
reserved DHCP is recommended. The default address is shown on the front of the unit:
IP Address: 192.168.123.123
Subnet Mask: 255.255.255.0
Gateway: 192.168.123.1
Initial Setup
Connect the GRSE Series unit to your computer using a crossover cable or hub/switch.
Windows XP
On your computer, go to “Start > Settings > Control Panel > Network and Dial Up
Connections”
Right click on “Local Area Connection” and select “Properties”
Select “Use the following IP address”. Use these settings:
IP Address: 192.168.123.1
Subnet Mask: 255.255.255.0
Gateway: Leave blank
Click “OK” twice.
The unit should now be accessible in a web browser via the unit’s permanent IP address:
http://192.168.123.123/. See Unit Configuration (page 21) for details.

Web Interface
Overview
The unit is accessible via a standard, unencrypted HTTP connection as well as an encrypted
HTTPS (SSL) connection. The following web pages are available:
Sensors Page
The front page, Sensors, gives both instantaneous and historical views of the unit’s data. Real
time readings are provided for all sensor data next to historical graphs.
Optional cameras may be added and their live snapshots are shown on this page. Plug-and-
play sensors appear below the internal sensors when attached.
The menu bar allows access to the rest of the Environmental Monitoring Unit’s functionality.

Logging Page
The Logging page allows the user to access the historical data by selecting the desired sensors
and time range to be graphed. Selected sensor values are logged into the data file at a rate of
one point per minute. Please note that although data is logged once per minute, all sensor data
used in the real time display and alarm functions is read at least once every 5 seconds for
internal sensors and once every 30 seconds for external sensors. On GRSE2X16 units only,
checked readings are displayed on the LCD module. Recorded data is available for download in
a comma-separated values (CSV) file.

Display Page
The Display page allows the user to assign friendly names to internal and attached sensors as
well as change the default temperature unit of measure for sensors. The display page also
allows the user to select between the default and classic web page layouts. The default
