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.

Installing the HP Rack Sensor Array or HP Three Point Sensor Array

1.Ensure the rack doors are free from dust before installing the sensor array.

NOTE: The sensor array has labels that indicate the location where the array string must be installed. Before installation, verify that you are installing the array string to the correct location.

2.Verify that you are installing the correct sensor string to the correct side of the rack.
