Introd uction 1 1.0 I NTRODUCTION The Liebert OpenComms™ EM is a compact, half-duplex de vice designed t o mo nitor temperature, humidity, water dete ction and contact closure and not ify pe rsonnel when those con ditions exceed user-defined limits.
Introd uction 2 1.1 Overview The OpenComms EM features indicator li ghts on the front, as shown in Figure 1 . Figure 1 Front view (EM PDU & vEM-14 contr ollers shown) 1.1.1 Dimensions and Mounting Overview - EM & EM PDU Controll ers • The unit is 4.
Introd uction 3 1.1.3 Connectors on Back of Unit The back of the OpenComms E M, shown in Figure 2 , has an input p ower so urce, sensor ports, a modem port and an Ethernet port. The EM PDU an d vEM-14 controllers have serial ports, and vEM-14 controllers also have 10 dry contact inputs.
Introd uction 4 1.2 Indicators The front of the OpenComms EM has in dicators that show input power to the unit and the status of various connections, as shown in Figure 3 and descri bed in Table 2 .
Installation 5 2.0 I NST ALLATION This section provides instru ctions for installing, mounting and connecting power and other cables to the OpenComms EM. 2.1 Inst allation Considerations The OpenComms EM must be installed indoors where el ectrical service is available.
Installation 6 2.2 Decide on Placement of the OpenComms EM The unit may either be placed on a level surface or mounted on a w all, depending on the user’s appli- cation and the location of equipm ent to be connected and monitored. vEM-14 controllers may also be mounted in a rack.
Installation 7 2.2.2 Mounting the Unit on a W all or in a Ra ck (vEM-14 Controllers) The vEM-14 controller may be mounted on a wall or in a rack, such as the Liebert Foundation.
Installation 8 2.3 Make Connections All ports are on the back of the OpenComms EM. The port placement and port labels diff er for each model. Refer to Figure 2 for your mode l. 2.3.1 Connect Power to the Unit • Connect the DC power adapter to the DCN/Powe r po rt on the back of the OpenComms EM, as shown in Figure 2 .
Assign an IP Address 9 3.0 A SSIGN AN IP A DDRESS After connecting the OpenComms EM device to your networ k, the next step is to iden tify the device to the network by assigning an IP address.
Assign an IP Address 10 3.2 Use ARP to Assi gn an IP Address This method may be preferable if you are not usi ng a Microsoft host. To use the ARP command: 1. Open a command prompt. In Wind ows, one way to do this is: • Click on the Start button, then on Run .
Web Interface Overview 11 4.0 W EB I NT ERFACE O VERVIEW This section provid es a quick look at th e OpenComms EM Web interface and the viewing and con figu- ration functions accessi ble through tabs at th e top of the window. For step-by-step instruct ions on using the Web interface, proceed to 5.
