NTI SERVER ENVIRONMENT MONITORING SYSTEM
INTRODUCTION
The ENVIROMUX-SEMS-16 Server Environment Monitoring System (ENVIROMUX) provides a way to supervise, from a
remote location, the environmental conditions and security in cabinets and rooms containing servers, hubs, switches and other
network components. Input data is filtered, collected, analyzed and processed to instantly and accurately display the status of the
room. The user is able to specify parameters for all monitored conditions: if the parameters are exceeded, the unit will signal an
alarm, which may include several pre-defined processes.
The ENVIROMUX-SEMS-16 monitors the internal temperature and humidity of the unit, giving readings that can be used
as an estimate for the conditions of other nearby rack components. Additionally, it is capable of monitoring a maximum of 16
external sensors (available from NTI) and up to 8 additional contact-type sensors (often called open-collector, contact-closure,
relay-style, normal-open, or normal-closed). ENVIROMUX includes 4 output relays to control devices such as door locks,
keypads, and circulation fans and two outputs specifically for the connection of an alarm siren and/or beacon.
The external sensors sold by NTI will monitor temperature and humidity, monitor AC line voltage, frequency, and
current, detect smoke, motion, vibration, glass breaking, a door opening, and detect the presence of water on a flat surface (such
as the floor). The temperature and humidity sensors will provide current readings as well as alerts when thresholds are exceeded.
The AC line monitor detects AC line input voltages between 50~250V AC, the Frequency (Hertz) between 47~63Hz, and the
Power (Current) up to 12 amperes from a single AC line. The remainder of the sensors will simply provide alerts. These sensors
can be manufactured by any third party, provided the alert notification method is compatible. Each of the aforementioned NTI
sensors will connect to the ENVIROMUX via RJ45 connectors and cat5 cable. The ENVIROMUX can also work with both 4-wire
and 2-wire contact-style sensors (4-wire sensors require a power connection, 2-wire do not). Screw terminals are provided for the
connection of external contact-style sensors.
The Ethernet will provide the main user interface for the ENVIROMUX-SEMS-16. The ENVIROMUX will provide data
logging that can be viewed via a web browser and provide alerts via email, Syslog, SNMP traps, SMS text messages and front
panel LEDs.

• RJ45 Sensors include Temperature, Humidity, Temperature and Humidity, Water, Vibration, Smoke, Motion Sensor,
Glass break detector and more
• Monitors server room environmental conditions remotely
• Alerts users of environmental faults (temp too high, water, etc) via email, Syslog, SMS messages, SNMP traps,
Illuminated front panel LEDs, or notifications on a web page
• Provides control for devices such as door locks, keypad, or a circulation fan via digital outputs (1A / 30 VDC, .5A /
100VAC)
• Full configuration via web page
• Limited configuration via SNMP, Telnet or RS232 interface
• Browser independent (IE, Netscape, Mozilla, Opera)
• Outgoing mail using SMTP or SMTP over SSL for alert notifications
• Configurable Alarms to match specific user schedule

Sensor Attachment
Note: It is very important to locate the temperature and/or humidity sensors away from ventilation sources and fans.
1. Connect each external sensor having an RJ45 male connector on it (ENVIROMUX-STS, ENVIROMUX-SHS, ENVIROMUXSTHS, ENVIROMUX-LDS) to one of the female connectors labeled "RJ45 Sensors" on the ENVIROMUX. Male connectors
should snap into place. See page 72 for wiring specification and pinout.
Note: Shielded cable is
required between the
sensor and the ENVIROMUX
to maintain CE compliance
of the sensor.
Figure 4- Sensors connected by cables with RJ45 connectors
Note: If the ENVIROMUX-LDS Liquid Detection sensor is installed, 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 5)
Figure 5- ENVIROMUX-LDS sensor mounting
2. Some sensors do not have RJ45 connectors on them
and instead have terminal blocks. These can either be
connected to the "DIGITAL IN" connectors or they can
be terminated and plugged into the remaining RJ45
connectors (see Figure 6). (The illustration uses CAT5
patch cable to make cable connection easy.) Examples
of these sensors include ENVIROMUX-IMD,
ENVIROMUX-IMD-MW, ENVIROMUX-EMD-CM,
ENVIROMUX-VSS, ENVIROMUX-SDS, and
ENVIROMUX-GBS. ( For more on these and other
sensors, see pages 2 and 3.)
Note: For sensors requiring 5VDC power source,
substitute the wire connected to pin 4 (see page 73)
instead of pin 7.
Figure 6- Contact sensor wired to RJ45 socket

NTI SERVER ENVIRONMENT MONITORING SYSTEM
3. To connect contact sensors without using RJ45 connectors, terminal blocks have been provided labeled "DIGITAL IN". Two
wire switch-only type sensors can be connected to the plus (+) and minus (-) terminals of each or 4 sets of terminals. If the
sensors require a 12V power source to operate, additional 12V and ground terminals have been provided for each set of
terminals. Connect each two-wire or four-wire contact sensor using 16-26 AWG wire.

NTI SERVER ENVIRONMENT MONITORING SYSTEM
OVERVIEW - USE AND OPERATION
The ENVIROMUX is controlled via RS232 or Ethernet using a terminal emulator, web browser, or SNMP monitor. The
user interfaces are for viewing and configuring sensor data and system settings. However, full configuration of the system can be
done only through the Web browser due to graphics limitations in the other interfaces.
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 log settings can also be configured. All settings are saved in memory when applied. A user may also restore the
unit back to its default settings at any time via the web interface (see page 61).
Individual sensor status pages are available for each connected sensor. A sensor summary page allows the user to view
the connected sensors’ current values, threshold settings and alert statuses. Also, the user can view recorded sensor readings
that have been stored in the system data log.
Sensors
The ENVIROMUX provides 16 RJ45 sensor input jacks and 8 screw terminals ports. Some available sensor
configurations include Temperature, Humidity, or Temperature+Humidity, Liquid, Vibration, Smoke, Motion Sensor, Glassbreak
detector, and AC Line Monitors. See page 2 for more on available sensors.
page 20). 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).
closure / open-collector type that operate on 12VDC and 50mA, with a maximum load resistance of 10kΩ or less. (See page 24
for more info.)
IP Assignment
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 20). These settings must be configured properly in order
to access the ENVIROMUX web interface.
User Management
local password authentication. Each user may be assigned "User" or "Administrative" privileges. Users accessing the
ENVIROMUX will be granted access to only the monitoring functions, and will be able to view the log. An account with
"Administrative" privileges has all of the privileges necessary to view and configure network settings, add/edit/delete other user
accounts, configure sensors, etc..
The temperature/humidity sensors have been given factory default settings and thresholds that can be changed (see
Sensors connected to the terminals labeled "Digital In" must be manually configured, and can be any sensor of contact-
An IP address can be assigned to the ENVIROMUX through any of three methods:
• Using the NTI Device Discovery Tool (page 20)
• Through the web interface on the Network page (page 37)
• Using the RS232 interface (page 54)
Initially, IP configuration will be the easiest to change using the NTI Device Discovery Tool (found on the CD),
The ENVIROMUX supports up to 16 user accounts plus the root account (page 39). Each user account is protected by
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 alert notifications are provided. Also, there is an adjustable alert delay time 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 29 and sample on page 48) will be provided through any or all of five main
methods:
• visible notification via the user interfaces (red LED on front panel, beacon, alert on webpage)
• emails
• SNMP Traps
• SMS Messages
• Syslog Messages
17
NTI SERVER ENVIRONMENT MONITORING SYSTEM
Data and Event Logging
The ENVIROMUX can log sensor readings, sensor alerts, alert handling, sensor connections/removals, and user
logins/logouts. The logs can be viewed at any time through the web interface (page 48). Additionally, as entries are generated,
they can be emailed or sent as SNMP traps. Entries can be deleted from the logs via the web interface. The maximum size of
each log is 1000 entries, listed in chronological order. Each log’s behavior upon reaching this maximum size can be configured,
allowing the log to either wrap (overwrite oldest entries), stop logging, or clear and start over. The entire log can be downloaded
as a plain text file from the web interface at any time. Log entries can be removed individually, in groups, or all at once.
Email
The ENVIROMUX can access an outgoing SMTP server (authenticated or non-authenticated, with or without SSL
encryption) to send email. Outgoing mail may contain pre-formatted alert notifications or data log messages (samples on page 48
and 49). The user can configure what conditions cause emails to be sent. The ENVIROMUX’s email address, as well as SMTP
server information and the email addresses to which emails are sent, can be configured on the Network Setup page through the
web interface (page 37). Up to 17 outgoing email addresses (112 characters maximum including commas) may be configured
(corresponding to the 16 user and 1 root email addresses).
Syslog
The ENVIROMUX 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 in each user profile (page 41). For a SYSLOG message to be sent, put a
checkmark in the "Syslog" box. Enter an IP address in the “Email address” box and click Apply.
SNMP
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. Click on the checkbox for SNMP under contacts (page 41) for each user that should
receive SNMP messages. The SNMP agent supports both SNMPv1 and SNMPv2.
Note: The SNMP MIB file (sems-16-v1.xx.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.
The ENVIROMUX can send alerts as SNMP traps when a sensor enters/leaves alert mode, and for all log events. Using
External GSM Modem
An external GSM modem can be connected to allow the system to send alert notifications via SMS messages. When a
sensor crosses a threshold, an alert notification can be formatted to SMS message (see page 41) and the modem could transmit
the message to a pre-specified cellular number. The external modem can be supplied from an external power supply or from the
provided 12V.
Power-on/Reset Operation
On power-up, after going through its boot sequence, the ENVIROMUX 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 60 seconds after power is applied) to view and configure
properties of the system and its sensors.
FYI: The boot sequence can also be initiated manually using the Reset button. See page 64 for details.
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 through the RS232 port until valid network settings are assigned to
the device (see page 37). The RS232 provides only limited configuration options, pertaining mostly to Ethernet settings.
Alert notifications will only be able to be viewed through the front panel until network settings are configured. Email and
SNMP alert notifications must be configured within the web interface (page 36) before these methods can be used. The network
settings must be compatible with the physical network to which the ENVIROMUX is attached. Once these configurations are
made, they will be saved in the unit, even if the ENVIROMUX is powered-OFF.
Expandability
have connected. Despite having multiple units, the user does not have to access the webpage of each ENVIROMUX individually.
Up to 4 units can be cascaded such that all of the data from each of the units can be displayed on a single format.
Multiple ENVIROMUX units may be used together on one system, so as to increase the number of sensors the user can

There are 2 ways to cascade ENVIROMUX:
1. Direct Connect- The units can be connected together through an expansion cable that can be as long as 25ft
(depending on how many units are cascaded). See page 14 for how to install with an expansion cable.
2. Ethernet Connect- The units can be connected via the Ethernet to expand the number of sensors. All units must be
on the same LAN.
A master unit will poll each of the slave units and present all of the data in a combined group from either of the user
interfaces. A maximum of 4 units can be cascaded.
Note: For ENVIROMUX units used as slaves in a cascaded system, the Siren, and Beacon terminals are not cascaded
and are therefore not useable on slave units. Only the additional sensor inputs and the output relays will be seen by
the master unit.

DEVICE DISCOVERY TOOL
In order to easily locate the ENVIROMUX on a network, the NTI Device Discovery Tool may be used. A link to the Discovery
Tool is provided on the web page that appears when you insert the instruction manual CD provided into your CD ROM drive.
Click on the link or browse the CD and click on the file discover.html . This will open your browser and display the Device
Discovery Tool page.
Note: The Device 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.
Note: The computer using the Device Discovery Tool and the ENVIROMUX must be connected to the same physical
network in order for the Device Discovery Tool to work.
