INTRODUCTION
The ENVIROMUX-MINI Server Environment Monitoring System is designed to monitor, from a remote location, the critical
environmental conditions in cabinets and rooms containing servers, hubs, switches and other network components. Specifically,
the ENVIROMUX-MINI will monitor temperature, humidity, and detect the presence of water on a flat surface (such as the floor).
The unit also has four sets of terminal block pairs for the connection of contact-closure sensors. Remote monitoring is provided via
a 10BaseT Ethernet web interface. The input data is filtered, collected, analyzed and processed to allow the user to configure it to
meet individual requirements. The user is able to specify parameters for all monitored signals. When a sensor exceeds the
configured threshold, the unit will signal an alert. Alert methods include email, SMS, SNMP traps (MIBs), web-page alerts, and a
visual indicator (red LED).

INSTALLATION
Mount the Unit
The ENVIROMUX-MINI can either be placed on a solid surface, mounted to a wall, or mounted to an accessible surface within
rack (Zero-RU). To mount to a wall or other surface, first remove the screws holding the mounting tabs to the rear of the box.
Rotate the tabs such that they extend from the back of the box, and attach the tabs with the screws removed. Now the
ENVIROMUX-MINI can be secured to any convenient surface. Use appropriate hardware (not supplied) when mounting.
Figure 1- Rotate the tabs for Zero-RU mounting
DIN Rail Mounting
The ENVIROMUX-MINI-D is for mounting to a DIN rails in a server rack. It is supplied with a DIN rail clip on the back. With the
clip installed, it can be readily snapped to a DIN rail and easily removed. Press the side of the clip with the metal spring in it
against the channel, rotate the ENVIROMUX-MINI-D into position, and release the pressure. Reverse the procedure to remove it.

Connect Sensors
1. Connect the desired sensors (ENVIROMUX-T, RH, or TRH- sold separately) to the available ports on the ENVIROMUX-
MINI. Plug the RJ45 connectors to either of the two ports marked "TEMPERATURE/HUMIDITY". The ENVIROMUX-T,
RH, or TRH sensors can be secured anywhere that the temperature and/or relative humidity need to be sensed. Power-
cycle the ENVIROMUX-MINI after sensors have been plugged-in.
Note: Mounting the sensor in the path of a fan or on a heated surface may affect the accuracy of the sensor’s readings.
Note: For best results, use the ENVIROMUX-T-IND with model ENVIROMUX-MINI-IND (see Sensors, page 11).
Figure 3- Connect sensors to ENVIROMUX-MINI
2. Connect the optional liquid detection sensor (ENVIROMUX-LD- sold separately) to the terminals marked "WATER" or to the
terminals marked “CONTACTS”. The two-wire cable provided can be extended to a total cable length of up to 1000 ft using any
two conductors (minimum 18AWG for 1000 feet).
The twisted orange sensing cable should be placed flat on the surface (usually the floor) where liquid detection is desired. If tape
is required to hold the sensor in place, be sure to only apply tape to the ends, exposing as much of the sensor as possible. At
least 5/8" of the sensor must be exposed for it to function. (See Figure 4)
Figure 4- Secure liquid detection sensor with tape

NTI MINI SERVER ENVIRONMENT MONITORING SYSTEM

3. Up to four dry-contact sensors or additional liquid detection sensors can also be connected to the terminals marked
“CONTACTS”. Sensors with 16-26 AWG connection wires, that operate on 5V at 10mA maximum current may be used. A
contact resistance of 10kΩor less will be interpreted by the ENVIROMUX-MINI as a closed contact.
To install the dry-contact sensor(s):
A. Attach the positive lead to a terminal corresponding to a "+5V" marking on the ENVIROMUX-MINI and the ground lead to
the next terminal to the right that will correspond to a marking on the ENVIROMUX-MINI. Tighten the set screw
above each contact. Terminal sets are numbered 1-4.
B. Mount the sensors as desired.
Figure 5- Terminal block for contact sensors
Note: The terminal block is removable for easy sensor wire attachment if needed.
Shielded cable must be used to connect to the DRY CONTACT ports in order to meet CE emission requirements.
Connect the drain wire of the shield to the ground ( ) terminal of the dry contact in addition to the contact return wire.
To install additional liquid detection sensors, just apply the two wires of the sensor to the +5V and terminals for a
numbered contact. It doesn’t matter which wire goes on +5V or ground when wiring liquid detection sensors.
Connect to Ethernet
Connect a CAT5 patch cable (RJ45 connectors on each end wired pin 1 to pin 1, pin 2 to pin 2 etc) from the local Ethernet
network connection to the connector on the ENVIROMUX-MINI marked "ETHERNET".
Figure 6- Connect ENVIROMUX-MINI to the Ethernet
For direct connection from a PC to the ENVIROMUX-MINI, use a crossover cable. See page 27 for crossover cable
pinout.
Note: The Ethernet port that the ENVIROMUX-MINI is connected to should be configured for 10Mbps half duplex.
Shielded CAT 5,5e, or 6 cable must be used to connect to the ETHERNET and RS232 ports in order to meet CE emission
requirements.

OVERVIEW - USE AND OPERATION
The ENVIROMUX-MINI is controlled via a web interface using a browser, which is for viewing and configuring sensor
data and system settings. A sensor summary page allows the user to view the connected sensors’ current values, threshold
settings and alert statuses. Individual sensor status pages are available for each connected sensor. Also, the user can view
recorded sensor readings that have been stored in the system data log.
The web interface allows for the configuration of the thresholds for all attached sensors, their alert methods, and the
formats of the alerts. In addition, network information (IP address, subnet mask, default gateway, DNS, etc.), user administrative
settings, and data logging settings can also be configured. All settings are saved in memory when applied. A user may also
restore the unit to its default settings via the web interface or the Restore button on the ENVIROMUX-MINI (see page 27).
Sensors
The ENVIROMUX-MINI provides two Temperature/Humidity sensor inputs, both RJ45 jacks. Available sensor
configurations include Temperature (ENVIROMUX-T), Humidity (ENVIROMUX-RH), or Temperature+Humidity (ENVIROMUX-
TRH). For the ENVIROMUX-MINI-IND for best results use temperature sensor ENVIROMUX-T-IND (see note below).
The ENVIROMUX-T temperature sensor is capable of measuring temperatures from 32°F to 104°F, with an accuracy of
±1.35°F (0°C - 40°C , ±0.75°C). Temperature can be displayed in either Celsius or Fahrenheit. The humidity sensor is capable of
measuring relative humidity percentages ranging from 20-80% with ±5% accuracy over the sensor temperature range.
Note: ENVIROMUX-T-IND temperature sensor (for the ENVIROMUX-MINI-IND) has a temperature range of 32°F to
167°F (0°C - 75°C). The ENVIROMUX-T/RH/TRH sensors can be used with the ENVIROMUX-MINI-IND, but they will not be
accurate above 104ºF.
The temperature/humidity sensors have been given factory default settings and thresholds that can be changed (see
page 16). Sensor readings can be reported continuously, only when readings change, or at a regular rate (for instance, a
temperature reading could be updated once each hour).
Sensors connected to the terminals labeled "CONTACT" must be manually configured, and can be any sensor of
contact-closure / open-collector type that operate on 5VDC and 10mA, with a maximum load resistance of 10kΩor less.
The liquid detection sensor (ENVIROMUX-LD) will warn the user(s) of flooding. It will detect and report the presence of
any conductive liquid (typically water) covering an area at least 5/8 inch in diameter and 1/8 inch deep.
IP Assignment
An IP address can be assigned to the ENVIROMUX-MINI through either of three methods:
•Using the NTI Discovery Tool (page 13)
•Manually through the web interface on the Network page (page 16)
•Automatically by a DHCP server (page 16)
Initially, IP configuration will be the easiest to change using the NTI Discovery Tool (found on the CD), which will search
for NTI devices on the user’s network and allow IP assignment to them through its web interface. Other settings for subnet mask
and default gateway may also be configured (see page 13). These settings must be configured properly in order to access the
ENVIROMUX-MINI web interface. Default settings are shown in Figure 13 on page 16. Alternatively, the network settings can
be assigned automatically by a DHCP server, as indicated on page 16.
User Management
The ENVIROMUX-MINI supports up to 8 user accounts and one Guest account (page 20). Each user account is
protected by local password authentication. Each user may be assigned "User" or "Administrative" privileges. Users accessing
the Guest account will be granted access to only the monitoring functions, and will be able to view the log. An account with "User"
privileges may view and configure sensor settings, the log, general system settings, email settings, time settings, and their own
user password. An account with "Administrative" privileges has all of the privileges of a "User" account, in addition to being able
to view and configure network settings, add/edit/delete other user accounts, and enable/disable the Guest account.
Alerts A high and low threshold limit can be set for each temperature or humidity sensor within the operating range of the
sensor. Each open collector/contact-closure sensor can be set as normally-open or normally-closed. When a sensor takes a
reading that is outside a threshold or a contact-closure sensor is not in its normal condition, an alert notification can be generated.
The user can specify how often and the maximum number of alert notifications to be provided. Also, there is an adjustable
hysteresis involved with alert notifications. This means if a sensor’s readings are moving in and out of the threshold boundaries
within a configurable period of time, additional alert notifications will not be sent. Alerts may be sent if the condition of the sensor
returns to normal or back within its threshold boundaries. Alert notifications (page 24) will be provided through any or all of these
methods:
•visible notification via the user interfaces (red LED on front panel, alert on webpage)
•emails
•SNMP Traps
•Syslog messages
•SMS messages

Data Logging
The ENVIROMUX-MINI can log sensor readings, sensor alerts, alert handling, and user logins/logouts. The log can be
viewed at any time through the web interface (page 23). Additionally, as entries are generated, they can be emailed or sent as
SNMP traps. Entries can be deleted from the log via the web interface. The maximum size of the data log is 100 entries. The log’s
behavior upon reaching this maximum size can be configured, allowing the log to either wrap (overwrite oldest entries), or stop
logging. The entire log can be downloaded as a plain text file from the web interface at any time (see "View the Log" on page
23).
Email The ENVIROMUX-MINI can access an outgoing SMTP server to send email. Outgoing mail may contain pre-formatted
alert notifications or data log messages. The user can configure what conditions cause emails to be sent. The ENVIROMUX-
MINI’s email address, as well as SMTP server information and the email addresses to which emails are sent, can be configured
on the Email page through the web interface (page 17). Up to 3 outgoing email addresses (112 characters maximum including
commas) may be configured. Only an unauthenticated email address can be used to send email.
SNMP The ENVIROMUX-MINI can send alerts as SNMP traps (V1) when a sensor enters/leaves alert mode, and for all log
events. Using an SNMP MIB browser, a user can monitor all sensor statuses and system IP settings, as well as configure sensor
thresholds, sensor names, and the system name. The destination for SNMP traps can be configured on the Network page
(page 16).
Note: The SNMP MIB file (enviromux-mini.mib), for use with an SNMP MIB browser, can be found on the manual CD.
Click on the link to open the file, then save the file to your hard drive to use with the SNMP MIB browser.
Syslog
The ENVIROMUX-MINI can send alerts as Syslog messages when a sensor enters/leaves alert mode, and for all log
events. The destination for Syslog can be configured on the Log Methods page (page 24).
SMS
The ENVIROMUX-MINI can send alerts as SMS message when a modem (GSM or 3G Serial) is connected (page 10).
The phone number destination for all SMS messages is configured on the sensor configuration page (page 21).
Note: Only one phone number can be used. If the phone number is changed for one sensor, the change is automatically
applied to all sensors.
Note: This feature requires firmware version 1.31 or higher.
WAP
The ENVIROMUX-MINI can be accessed to view the summary page for sensor status from a mobile phone with WAP 2.0
support (see page 26).
Note: This feature requires firmware version 1.34 or higher.
Power-on/Reset Operation
On power-up, after going through its boot sequence, the ENVIROMUX-MINI will launch the monitoring application, load
any stored configuration values, and immediately identify and begin taking readings from any connected sensors. Alerts will be
reported using the configured alert methods, and data will be logged using the stored preferences. A user can log in at any time
after the system has launched the monitoring application (approximately 5 seconds after power is applied) to view and configure
properties of the system and its sensors.
Note: It is normal for the red LED (Fault Indicator) to be illuminated for a few seconds upon startup.
Out-of-Box Operation
The operation of the unit directly out of the box is nearly identical to the Power-on/Reset operation. However, information
about the unit will only be able to be monitored and controlled once valid network settings are assigned to the device (see IP
Assignment on page 11). The network settings must be compatible with the physical network to which the ENVIROMUX-MINI is
attached. Also, alert notifications will only be able to be viewed through the user interfaces (LED, web page). Email and SNMP
alert notifications must be configured within the web interface (page 16) before these methods can be used. Once these
configurations are made, they will be saved in the unit, even if the ENVIROMUX-MINI is powered-OFF.

DEVICE DISCOVERY TOOL
In order to easily locate the ENVIROMUX-MINI on a network, and change the IP settings, the NTI Device Discovery Tool may be
used. A link to the Discovery Tool is provided on the web page that appears when the instruction manual CD is inserted into the
computer's CD ROM drive. Click on the link or browse the CD and click on the file discover.html . This will open a browser and
display the Device Discovery Tool page.
Note: The Discovery Tool requires the Java Runtime Environment to operate. A link to the web page from which it can
be downloaded and installed is provided on the CD. A Windows compatible version of the software is also on the CD.
Note: The ENVIROMUX-MINI and the computer using the Device Discovery Tool must be connected to the same physical
network and in order for the Device Discovery Tool to work.
Note: There cannot be a firewall between the computer using the Device Discovery Tool and the ENVIROMUX-MINI. If a
firewall is present between them, the Device Discovery Tool will not work.
Figure 9- Device Discovery Tool page
Use the Device Discovery Tool to display all NTI devices on your network, along with their network settings. Follow the
instructions on the Device Discovery Tool page to use the tool and to change the device settings if so desired.
FYI: The "Blink LED" button will
blink the green "PWR" LED on the
ENVIROMUX to identify which unit is
associated with the settings shown.
Note: If the IP address is set to be obtained automatically from a DHCP server (see page 16, Figure 13), then the IP
address will not be able to be manually changed. If an attempt is made, the DHCP server will automatically change it
back to the automatically assigned address.

USE AND OPERATION VIA WEB INTERFACE
A user may monitor and configure the settings of any device connected to the ENVIROMUX-MINI using the Web Interface via a
web browser (see supported browsers on page 6). To enable the Web Interface, connect the ENVIROMUX-MINI to the Ethernet
(page 9). A user can login to the default IP address (shown below), or if the IP address is not known, use the Device Discovery
Tool (page 13) to determine and, if desired, setup the network settings. In either case, to access the web interface controls, the
user must log in.
Log In
To access the web interface, type the current IP address into the address bar of the web browser. (The default IP address is
shown below):
Note: If the HTTP Server Port number is changed (page 16) from port 80 (default), then the port number will need to be
added to the IP address (i.e. if the port number is changed to 95, then the IP address would be http://192.168.1.21:95)
A log in prompt requiring a username and password will appear:
Username = Administrator
(uppercase letter for "A"
only)
Password = admin
(lower case letters only)
Note: usernames and passwords are case
sensitive
