    Chapter 3. Installation 3.1 General This chapter explains in detail the requirements and procedures for the installation of the Fiber Multiplexer Standalone/Rack Mount Fiber Optical Multiplexer. 3.2 Site Preparation Install the Fiber Multiplexer within reach of an easily accessible grounded AC outlet. The outlet should be capable of furnishing 90 to 250 VAC (20 to 60 VDC for DC supply).

  • Page 26: Electrical Installation

    Chapter 3. Installation 3.4 Electrical Installation 3.4.1 Power connection For a model with AC power supply, AC power (90~250VAC) is supplied to the Fiber Multiplexer through a standard IEC 3-prong receptacle, located on the rear of the chassis. For a model with DC power supply, DC –48V (20~60VDC) is connected to the terminal block, observing the proper polarity.

  • Page 27: Rear And Front Panel Connectors

    Chapter 3. Installation 3.4.2 Rear and Front panel connectors All 4-Channel Port Cards install into the rear of the Fiber Multiplexer. The back plane provides both DC power to the 4-CHANNEL Port interface cards and routes signals from the cards to the multiplexing circuitry.

  • Page 53: Chapter 6. Snmp Operation

    Chapter 6. SNMP Operation 6.1 General The Simple Network Management Protocol (SNMP) is one of many protocols in the Internet Protocol (IP) suite. SNMP is the protocol recommended specifically for the exchange of management information between hosts residing on IP networks. Network management allows you to monitor and control network devices remotely using conventional computer network technology.

  • Page 54: The Management Information Base

    Chapter 6. SNMP Operation 6.3 The Management Information Base The management information base (MIB) includes a collection of managed objects. Managed objects are defined as parameters that can be managed, such as specific information on device configuring or on performance statistics values. The MIB includes the definitions of relevant managed objects (MIB variables) for the specific node.

  • Page 55: Snmp Communities

    Chapter 6. SNMP Operation Enterprise-specific MIB's are published and distributed by their creators, who are responsible for their contents. The MIB supported by the Fiber Multiplexer SNMP Agent follows RFC 1158 (MIB-II standard). 6.5 SNMP Communities To enable the delimitation of management domains, SNMP uses "communities". Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user.
