HW group Poseidon2 4002: Data center environment ...

Poseidon2 4002 is a system for remote monitoring of rack environmental conditions (occupies 1U). Measures temperature, checks if the lights are on or the doors are open in the server room, and more. Relay outputs (4x digital output) can activate fans or an additional light. Poseidon is SNMP compatible, includes a data logger, e-mail and SMS alerts. It can be connected to the SensDesk online portal or cloud sensor systems.

Poseidon2 4002 is a remote environment monitoring system for datacenters and server rooms.
It alerts to open door, high temperature and humidity, or other sensor readings. Typical applications include monitoring one or more racks, or the entire server room. Poseidon2 4002 can be mounted on the wall, on a DIN rail, or as a 1U device in a 19” rack.

Use your Poseidon to monitor your computer room temperature via SNMP (Nagios, Cacti, OpenView, ..) or with a smartphone app.

Poseidon2 4002 can be used as a standalone environment monitoring device with email alerts or as a part of a complex monitoring system (SNMP or SensDesk online portal).

Sensors and detectors
Up to 16 external sensors, 12 detectors with a dry contact output, 4 relay outputs and a GSM modem can be connected. We supply temperature and humidity sensors (indoor/outdoor), light intensity sensors, DC/AC current and voltage converters.

Digital Inputs can be connected to smoke detectors, power failure detectors, water flood detection, and more. Relay outputs can be controlled over the Web, or according to the value of a connected sensor, for example to control air conditioning or ventilation.

E-mail and SMS alerts
When a value is out of a specified range, Poseidon2 sends an e-mail, a SNMP Trap, or a text message (SMS). Text messages (SMS) can be sent via an external GSM modem, or through a central “HWg-SMS-GW” text message gateway. Just a single SIM card can serve all your devices.

Web interface, software, mobile apps
The device can be accessed over the web, using a mobile phone app (Android, iPhone), or through an online portal. Temperature alarms, for example, can be sent by e-mail or SMS.

For data collection and monitoring, we recommend our HWg-PDMS application that displays graphs and exports data to MS Excel.
For “IF-THEN” event management (e.g. “If one out of 10 devices fails, send a SMS to the admin”), we provide the “HWg-Trigger” application for Windows.

For remote monitoring of several sites, the SensDesk.com online service can be used. It can display readings from sensors at multiple Poseidon2 units and other HW group products on a single screen. The online portal is configured over the web and all devices can monitored with a mobile phone app.

Poseidon2 can be connected to various monitoring systems. We support over 50 different third-party SNMP or SCADA applications.

Data logging

• Poseidon2 includes an internal flash memory for the data logger. Data are kept even if the power goes off.
• The logger has a capacity for 250,000 records. For Poseidon2 4002 working as a temperature logger with one temperature sensor and 4x DI, this means enough memory for 230 days (7.5 months) when logging every 300 [s] (5 minutes).

Tip: The HWg-PDMS application can, for instance, read data from the internal memory over e-mail or web interface.

Usage examples

• Server room environment monitoring
  • Temperature in a 19" cabinet and in the room
  • Remote environment monitoring (lights, power, fire protection system, ...)
  • IT monitoring of security systems (alarms, room / cabinet doors monitoring, ...)
• Remote environmental monitoring in a cabinet or in a datacenter
  • Temperature and humidity in the datacenter (inside racks, in the A/C outlet, under the raised floor)
  • Detection of redundant power failures
  • SNMP (SNMPv3) environment monitoring system
• Air-conditioning monitoring
  • A/C, temperature, humidity monitoring
  • Control of additional cooling in a room or in a rack
  • Alert to leaking water
• UPS / back-up generator monitoring
  Fuel level, diesel generator status, remote start over IP, monitoring of temperature and service contacts
  
  
• Remote I/O control and monitoring over the Ethernet
  Monitors a remote environment, sensor values can be fed into any SNMP system. Enables remote reading of dry contact inputs and remote control of relay outputs (to turn on HVAC, restart a server, start a diesel generator, ...).
  
  
• Industrial applications
  Remote monitoring of dry contacts, 4-20mA sensors or Pt-100 and Pt-1000 temperature probes.
  Data logger stores the values in the internal memory. Modbus/TCP protocol can be used for integration with SCADA systems.
  
  
• Cooler and freezer monitoring + alarm indication
  Measures temperature and humidity in a cooler or a freezer. When a value is out of a safe range, a relay output is activated to e.g. turn on a warning light or sound a horn. Suitable for monitoring storages of food or pharmaceuticals.
  We recommend the PDMS software to monitor temperature.
  
  
• Temperature and other measurements in a cloud
  Poseidon2 remote monitoring device can be connected to cloud systems. Contact us for details.
  
  
• Surveillance systems
  Sensor readings and detector states can be fed to IP camera systems of various brands. Digital Outputs can be used to turn on the lights in a certain zone or open/close gates.
  
  
• Smart buildings
  Sensor readings can be shared in several applications. Relay outputs can be controlled as remote I/O.

Server room: environment monitoring in the room

• When the main A/C in the server room fails (temperature in the room becomes too high), Poseidon2 4002 turns on back-up A/C and alerts the operator.
• Poseidon2 logs every opening of room or rack (cabinet) doors, can also send an e-mail.
• Many customers use e-mail alerts and detection of light turned on in a room to detect the arrival of an operator.
• Remote environment monitoring (humidity, power status, smoke detection, battery state measurement).
• Water leak detection with a 2D water leak detector (WLD) on the server room floor. Leaking water can be detected with the sensing cable at multiple places and detection zones.
• Humidity and temperature sensor monitors the dew point and operational conditions of supplementary air-conditioning.
• Smoke detector is powered directly from the power-out output of Poseidon2 4002, no additional power adapter is necessary.
• Server room status can be checked remotely in a smartphone app (available for Android and iPhone).
• Server room alarm monitoring can also take place over the web or e-mail.
• For remote monitoring of several datacenters, you can use the SensDesk.com online portal and monitor your devices with SensDesk mobile (mobile app for Android and iPhone).
  
  

Rack (cabinet): Remote environment monitoring

• Poseidon2 4002 monitors the rack environmental conditions:
  • Temperature too high at the air inlet/outlet
  • Front/rear door opening
  • Light turned on in the server room
  • UPS status (power outages)
  • Smoke detector
  • Temperature at critical points (disk arrays, servers)
• Relay outputs of Poseidon2 4002 can control:
  • Remote server restart
  • Fans
  • Light tower / cabinet indicators
  • Rack door lock
• Temperature sensors can be placed outside the rack and measure e.g. the room temperature or the temperature in another rack.
• To evaluate alarm situations and send alerts, we recommend the HWg-Trigger app for Windows.
• Poseidon logs the values to its internal memory. The log can be displayed and processed e.g. in the HWg-PDMS utility for Windows.
• Remote environment monitoring in a datacenter over SNMP
• Can be connected to BMS (Building Management System) or SCADA (Modbus/TCP).

SMS alerts: One SIM card for all your devices

• Poseidon2 4002 with a GSM modem can work as a SMS gateway for all your other HW group monitoring devices in the same LAN.
• Poseidon2 4002 with a GSM modem is a "SMS Gateway" for other devices – just as the dedicated “HWg-SMS-GW” product. Poseidon2 4002 offers somewhat lower throughput in terms of SMS per minute.
• Works entirely at the hardware level – as long as the LAN works, text message alerts will be sent.
• "Power OUT" terminals at the Poseidon unit can be used to power the GSM modem.

Multiple rack monitoring: 6 racks (12 sensors) monitored by a single Poseidon2 4002

• Poseidon2 4002 is located in one of the racks, where it also monitors the door with a door contact.
• The other five racks are equipped with a temperature and humidity sensor.
• Sensors are daisy-chained. Several sensors can be connected to a single active RJ11 port on the Poseidon2 4002.
• CAT5 cabling can be used to connect sensors in external racks.
• Temperature/humidity sensor can be also placed in the room, or at an air-conditioning outlet.
