ENVIROMUX-SEMS-16
Software Version 2.4
Quick Installation Guide
The ENVIROMUX-SEMS-16 Server Environment Monitoring System (ENVIROMUX) is designed to monitor, from a remote
location, the critical environmental conditions in cabinets and rooms containing servers, hubs, switches and other network
components. 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). Specifically, the external sensors sold by NTI will monitor temperature and humidity,
and 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 remainder of the sensors will simply provide alerts.
Remote monitoring is provided via a 10/100BaseT Ethernet web interface. 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,
SNMP traps, web-page alerts, and visual indicators (LEDs). Support for text messaging (with the connection of an external GSM
modem) is also provided.
Installation
1. Mount the ENVIROMUX to a rack.
2. Connect each of the sensors (purchased separately) to the ENVIROMUX.
A. Connect any RS485 sensors (i.e. ENVIROMUX-STS temperature sensor, ENVIROMUX-SHS humidity sensor,
ENVIROMUX-STHS temperature + humidity sensor, ENVIROMUX-LDS liquid detection sensor, ENVIROMUX-VSS
vibration sensor) to the "RJ45 Sensors" ports using CAT5/5e/6 patch cable.
B. Connect contact sensors (i.e. ENVIROMUX-GBS glass break sensor, ENVIROMUX-SDS smoke detection sensor, and
others) to the terminal blocks labeled “Digital In”. If sensors require a 12VDC power source to operate, 12VDC (50mA
max.) 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.
3. Connect the ENVIROMUX to the Ethernet for maximum remote system management using the “ETH” port and CAT5/5e/6
patch cable.
4. For limited local system control via RS232 connect a terminal to the “Console” port using a 9DB male-to-female cable. (The
ENVIROMUX is a DTE device.)
5. For control over additional devices using relay contacts (30VDC/1A, 100VAC/500mA max.) connect devices to terminal blocks
labeled “Output Relays”. Relay contacts will work as a switch to either open or close a circuit.
6. Connect the power cord.
