NTI SERVER ENVIRONMENT MONITORING SYSTEM
1
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.
