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.

INSTALLATION
Rack Mounting Instructions
The ENVIROMUX was designed to be mounted in a rack. It includes a rack mount kit to make attachment easy.
1. Attach the ears to the ENVIROMUX using the #6-32x3/16" flat Phillips-head screws (6) provided as shown in the
illustration below.
2. The holes in the ears should line up with pre-threaded holes in the sides of the ENVIROMUX. Tighten the screws
securely.
Figure 2- Secure rack mount ears to ENVIROMUX-SEMS-16
3. Install 4 cage nuts to the rack in locations that line up with the holes in the mounting ears on the ENVIROMUX.
4. Secure the ENVIROMUX to the rack using four #10-32x3/4” screws and cage nuts (provided). Be sure to tighten all
mounting screws securely.
Note: Do not block power supply vents in the ENVIROMUX case. Be sure to enable adequate airflow in front of and
behind the ENVIROMUX.
Figure 3- Mount ENVIROMUX in a rack
5. Attach all cables securely to the ENVIROMUX and where necessary supply adequate means of strain relief for
cables.

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, ENVIROMUX-
STHS, 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.
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
Note: Shielded cable is
required between the
sensor and the ENVIROMUX
to maintain CE compliance
of the sensor.

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.
¾Devices connected to DIGITAL IN terminals 1-7 must be rated at 50mA or less.
¾Devices connected to DIGITAL IN terminal 8 must be rated at 650mA or less.
FYI: The terminal block is removable for easy sensor wire attachment if needed.
Figure 7- DIGITAL IN Terminal Connections
4. Terminals have been provided for connection of the ENVIROMUX-BCN-R Beacon and ENVIROMUX-SRN-M Siren to
use for visual alerts and audible alerts when configured. Devices such as this can be installed in locations best suited
to get attention. All devices must be installed using 16-26 AWG wire.
Figure 8- Connect visual and audible external indicators
WARNING
Devices connected cannot
exceed 180mA contact
load.
NOTE: If used, the ENVIROMUX-
EDR-SF\ENVIROMUX-EDR-SCR
Electric Strike should be connected
to DIGITAL IN terminal 8 for power.

WARNING
Connect Output Devices
For connection of additional output devices to be controlled by the ENVIROMUX, terminals labeled "Output Relays" have
been provided. The 4 pairs of contacts will work as switches to either close or open (switch ON or OFF) when used. The
switch position is configured on the Sensor Configuration page (page 26).
OUTPUT RELAY dry contact ratings must not be exceeded. Dry contact rating:
DC 30V, 1A; AC 100V, 500mA. The OUTPUT RELAY contacts are not to be connected
directly to AC mains wiring.

Terminal Connection for RS232
To make a direct serial connection to the ENVIROMUX from a terminal with HyperTerminal via RS232, a 9DB female DCE
port labeled "Console" is provided. Connect a male-to-female 9DB cable from a serial port on the terminal to the 9DB
female connector on the ENVIROMUX. The cable should be wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc. )
Figure 10- Connect a terminal for direct RS232 serial communication
Ethernet Connection for Remote User Control
To make a remote connection, over the Ethernet, from anywhere on the local area network, connect a CAT5/5e/6 Ethernet
cable with RJ45 male connectors on the ends, wired straight through (pin 1 to pin 1, pin 2 to pin 2, etc.).
Note: To make a direct connection from a computer to the ENVIROMUX through the ETHERNET port, a crossover cable
is required. See page 72 or “PC-To-ENVIROMUX Crossover Cable”.
