Introduction The Dell™ Environmental Monitoring Probe (EMP) is an optional connectivity device that lets you remotely monitor the temperature, humidity, and status of two contact devices through a standard Web browser, providing greater power management control and flexible monitoring. Use the EMP with any Dell UPS equipped with a Dell Network Management Card (firmware v01.10.xxxx or later). NOTE: Download firmware updates for the Network Management Card from www.dellups.com. Figure 1.
• When temperature and humidity values exceed user-selectable limits, the event is logged in the card’s Event History log. • Compatible with any Dell Network Management Card (firmware v01.10.xxxx or later).
Installation This section explains unpacking and installing the EMP. Unpacking the EMP Verify the package contents (see Figure 2): • Dell Environmental Monitoring Probe • Ethernet cable • Installation accessories • Installation instructions • User’s guide (this document) Figure 2.
Installing the EMP To install the EMP: 1 If you plan to monitor one or two external contact devices, connect external contact closure inputs to the screw terminals on the EMP (see Figure 3 and Table 1). NOTE: Contact closure devices can be normally open or normally closed. Pins 1 2 3 4 Figure 3. Connecting External Contact Devices Table 1.
2 Locate the Ethernet cable (supplied). Connect one end of the cable to the RJ-45 port on the EMP, then connect the other end to the Settings port on the Network Management Card (see Figure 4). EMP Network Management Card Figure 4. Connecting the Cable NOTE: If the configuration cable is still attached to the Network Management Card, remove and store it for future use. NOTE: If the supplied cable is not long enough for your installation, you can use another Ethernet cable up to a length of 10m (33 ft).
Configuring the EMP This section explains how to: • Display temperature, humidity, and status of two contact devices through a standard Web browser • Change environment settings • View environment log data and save the data in a CSV format file Viewing Environment Status 1 Open your Web browser and connect to the Network Management Card’s IP address. The home page of the Network Management Card displays.
Temperature and humidity measurements are displayed in a graduated bar (see Figure 6). The red zones to the left and right of the bar represent the low and high thresholds. If notification is turned on, an alarm is generated when the measured value enters one of these zones. The cursor indicates the current reading. Low Threshold Red Zone High Threshold Red Zone Current Reading Figure 6.
Changing Environment Settings On the Environment Settings page you can: • Set the temperature and humidity thresholds that trigger a notification (and a graceful shutdown of the protected systems). • Configure and enable both contacts, as well as set upper and lower ranges of temperature and humidity that will generate SNMP Traps, and e-mail notification (if the card is configured to do so). 1 Select Settings from the Environment menu to display the Environment Settings page (see Figure 7). Figure 7.
2 Enter changes. Configurable environment settings are: Parameter Description Sensor name The name given to the EMP. Dell recommends using a name that identifies the location of the EMP. Temperature Choice of the temperature unit (°C or °F) from the list. High threshold (temperature) If the temperature exceeds the set threshold, a notification is triggered if enabled. The default value is 40°C / 104°F.
Parameter Description Notification Notification of each status change if enabled. When the Notification box is selected, the following functions are activated for each event selected: • Display in the list of current alarms • Consideration in the UPS log • SNMP trap generation • Notification by e-mail. The Environment Log check box must be selected on the Email Notification page.
Viewing and Saving Environment Log Data NOTE: Temperature and humidity measurements are recorded at an interval defined on the environment log interval on the System Settings page (refer to the Network Management Card user’s guide for information on system settings). By default, this period is 300 seconds. Each measurement is dated and stored in the log of the UPS’s communication card. The size of log files is limited by a time indexing system.
