By connecting your HP POD 40c G2 to a BMS system, you can monitor the various parameters and alarms. For more information, see "Navigating the ECS interface (on page 41)." The complete list of parameters and alarms that can be monitored will be discussed with your facilities personnel.
IMPORTANT: If your site does not have a BMS, HP POD 40c G2 ECS data can be sent to and viewed from a set IP address. Communication occurs through an Ethernet cable that is connected to the demarcation box (on page 63).
Satellite control boxes
The satellite control boxes facilitate communication from the ECS to the cooling system fans. Each satellite control box controls the fans in the zone that corresponds with its location.
The HP POD 40c G2 has six satellite control boxes, one box per cooling zone. Top view shown
Sensors
The HP POD 40c G2 has several temperature and pressure sensors that monitor the environmental factors and communicate data back to the ECS.
•The values from the temperature sensors are calculated together to determine an average temperature for each aisle of the HP POD 40c G2.
•The pressure sensors measure the differential pressure between the hot aisle and the cold aisle.
