IBM Environmental Monitoring Probe (EMP)
The Environmental Monitoring Probe (EMP) (part number 46M4113) is used to report local temperature
and humidity values and make that information available to management tools such as IBM Systems
Director Active Energy Manager (AEM). The EMP connects to the UPS via the Network Management
Card. The EMP is shown in Figure 11.

The Environmental Monitoring Probe has the following characteristics:
It connects to the Network Management Card (NMC) settings/sensor connection.
Its temperature and humidity thresholds are easily set to trigger alarm notifications or shut down the
protected system.
Its status can be monitored from the IBM Systems Director AEM or from the Network Management
Card web interface.
It measures temperatures between 0 and 80°C (32 and 176°F) with an accuracy of ±1°C.
It measures relative humidity between 10 and 90% with an accuracy of ±5%.
It can be located away from the UPS with a CAT5 network cable (up to 20 m (65.6 ft)).
Its user-selectable alarm thresholds enable you to define acceptable temperature or humidity limits.
It allows email notification through SMTP.
Figure 12 shows information retrieved from an EMP using the NMC web interface.
