Cisco ROSA-EM-BASE-AC=

The Cisco ROSA Element Manager (EM) is specifically designed to cost effectively monitor and control the transmission network of headends, hub sites, HFC outside plants, and transmitter sites. This unit manages the equipment that is co-located at the site where the ROSA EM resides, whether this equipment has an SNMP, serial (RS-232/422/485), or contact closure interface.The ROSA EM is a polling engine that actively polls all of the devices that it manages looking for problems. In the event a problem is detected, ROSA EM will send alarm notifications to the appropriate personnel via SNMP trap, email, pager, or SMS. ROSA EM communicates with the managed devices via proprietary protocols or contact closures, then translates this information to SNMP, which can be passed to a higher level network management system. When ROSA EM is configured to perform backup protection, it will automatically initiate pre-defined backup schemes that reroutes signals, activates, and configures standby devices, all within seconds of a device failure.The ROSA EM is a 2 RU high, 19-inch rack-mount embedded platform that operates without a monitor or keyboard. The operator uses a standard web interface with the ROSA EM via a simple easy-to-use GUI. Communication to the ROSA EM can be established over any LAN/WAN network that supports Ethernet. In addition, dial-in and dial-out (e.g., ISDN) is supported for cases where only a switched connection is available.
