HP Environmental Base Station installed on a rack
Overview: Installing a base station on a rack
The base station is a wireless device that collects temperature data from the external sensor arrays and sends
the information to the gateway. The base station has its own internal temperature and humidity sensors and
collects data to send to the gateway.
When the base station is installed on a rack, it is attached to either the HP Rack Sensor Array or the HP Three
Point Sensor Array. The base station sends its internal temperature and humidity readings and the external
temperature readings from the sensor arrays to the gateway.
Each sensor array is composed of sensor pods. Each pod has a thermistor that collects temperature data for
a specific location. The sensor array is connected to the HP Environmental Base Station, which collects all
thermistor readings and sends the readings to the gateway.
Two types of sensor arrays can be installed on the rack:
• HP Rack Sensor Array—The array is composed of six sensor pods. The array is designed for installation
on a rack. Three thermistors are on the front rack door of a cold aisle, and three thermistors are on the
rear rack door of a hot aisle.
• HP Three Point Sensor Array—The array is composed of three sensor pods. The array is designed for
installation on the front rack door of a cold aisle, hanging from a wall, or installed at the end of a rack
row.
You can install the sensor arrays on the inside of perforated rack doors or the outside of any rack doors. HP
recommends installing the sensor arrays on the inside of the rack doors, if possible.
NOTE: If your rack does not have a door, HP recommends installing the sensor array on the front
left rail of the rack.
NOTE: If you have hot air recirculation issues, then install an HP Three Point Sensor Array at the
end of your rack row to help identify the problem location.

CRAH/CRAC
Overview: Installing a base station on a CRAH/CRAC
The base station is a wireless device that collects temperature data from the external sensor arrays and sends
the information to the gateway. The base station also has its own internal temperature and humidity sensors
and collects data of its own to send to the gateway.
When the base station is installed on a CRAH/CRAC, it is attached to the HP Plenum Rated Sensor Array,
and sends its own internal temperature readings and the external temperature reading from the sensor arrays
to the gateway.
The sensor array is composed of sensor pods, each with a thermistor that collects temperature data for a
specific location. The sensor array is connected to the HP Environmental Base Station, which collects the
thermistor readings and sends the readings to the gateway.
The HP Plenum Rated Sensor Array is composed of two sensor pods, one that measures the temperature at the
supply side of the CRAH/CRAC, and one that measures the temperature at the return side of the
CRAH/CRAC.
There are two CRAH/CRAC installation configuration options:
• Single—(Standard installation configuration) The base station measures temperature and humidity on
the supply side of the CRAH/CRAC and measures only temperature on the return side of the
CRAH/CRAC.
• Dual—(Optional installation configuration) The base station measures temperature and humidity on
both the supply and return side of the CRAH/CRAC. The return air temperature is an average of six
thermistor readings.
