Network Management
ROSA™ EM - Element Management System
Description
The ROSA™ Element Manager (EM) is specifically designed
to cost effectively monitor and control the transmission
network of headends, hub sites and HFC outside plants, and
transmitter sites. This unit manages the equipment that is co-
located on the site where the ROSA EM resides, whether this
equipment has an SNMP, serial (RS-232/422/485) or contact
closure interface.
The main functions of the ROSA EM are to:
•
•
•
•
•
Monitor the health of the transmission network
Act as an SNMP proxy
Send alarm notifications when a problem occurs
Automatically backup failed devices
Perform local automation tasks
The ROSA EM supports several hundred Scientific-Atlanta and third-party devices. Support for new devices is
continuously being added to the ROSA EM, which can be exported to existing installations with a simple software
upgrade.
The ROSA EM actively polls all of the devices that it manages looking for problems and 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 their 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 interfaces with the ROSA EM via a simple easy-to-use and understand Web browser
client. 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.

(*) Note concerning Safety Extra-Low Voltage (SELV) Circuit Warning
To avoid electric shock and in order to comply with the product’s regulatory safety compliance certifications:
• Do not connect any I/O, signal or communication port to circuits falling beyond the requirements for SELV circuits
• Always verify voltage, current and energy levels of connected circuits against SELV requirements (for a full definition of SELV
requirements, refer to UL, EN or IEC 60950 standards for limit values).
• Ensure that only ‘Digital Input Ports’, Galvanic Isolated Digital Input Ports’ or ‘Relay Outputs’ are connected to outdoor circuits.
Important:
• SELV voltage limits for indoor connections are < 60 V DC (or peak) or < 42.4 V AC RMS.
• SELV voltage limits for outdoor connections are lower than those for indoor connections.
• Outdoor voltages should be no greater than 15 Vrms, 21.2 Vpk, and 30 V DC under normal operating conditions.
• Cabling of outdoor circuits must be shorter than 140 feet or 42 meters.
• In all cases it is needed to protect outdoor cabling by means of a Primary Surge Protector at the position where the wiring enters the
building.
• Outdoor cabling should be routed away and spaced with adequate clearances from power and lighting conductors.
• For installations in the United States, refer to the appropriate sections in the National Electrical Code (NEC).
• For installations in other countries, ensure that the installation complies with the National requirements taking in account the above-
mentioned recommendations.
