2 INTRODUCTION TO ERICSSON MINI LINK CRAFT Overview:The Ericsson MW Indoor comprises of the following:Radio Transmission Cabinet (RTC)AMM (Access Module Magazine)The RTC is the cabinet where the Ericsson equipment are been installed. Within it you have the AMM and other equipment like the SAU e.t.c
3 Access Module Magazine (AMM) The AMM is like empty mini equipment which in it can accommodate various Modules. The indoor plug-in units are installed in an AMM. The AMM can be fitted directly into a 19” or metric rack. It provides the mechanical housing and interconnection for the plug-in unit’s through the backplane. It has different slots according to design specification. There are like three (3) Design Specifications for AMM:2p Magazine6p Magazine20p MagazineEach specification is according to the number of MMU cards/ Site Design.
5 AMM 2pThe AMM2p has two half-height slots, one equipped with NPU3, NPU3B, or NPU3C, the remaining half-height slot can be equipped with LTU, ETU, SAU or SXU.The power supply is not included in NPU3, NPU3B, or NPU3C; it is separately integrated in the AMM on the left hand side. At the Right Hand Side are slots for Two (2) MMU’s. The AMM Kit delivery comprises:One assembled AMM 2pOne Rack Screw KitOne Earthen Cable, 1mOne NPU3, or One NPU3B, or One NPU3C.One RMMTwo MMUNote: AMM2p requires a DC cable RPM517560/nnnn which must be purchased separately.
6 AMM 6pAMM 6p C or D have four (D) or five(C) full-height horizontal slots, four (D) or two(C) half-height horizontal slots and two half-height vertical slots. They house one NPU3, NPU3B, or NPU3C, one or two PFU3B, and one FAU2.The remaining slots in AMM6pC/D can be equipped with MMU, LTU, SAU, AAU, SXU, SMU or ETU. An AMM6pC/D Kit delivery comprises:One assembled AMM6pC or one assembled AMM6pDOne Rack Screw KitOne Earthling Cable, 1mOneNPU3, or One NPU3B, or One NPU3COne RMMOne DC Connector KitOne FAU2One PFU3B, (one additional PFU3B Kit is needed for redundancy)
7 AMM 20pThe AMM20p has twenty full size slots of which 10 are available as standard. Additional slots can be made available by ordering the optional feature “AMM20p Slot Extension”. The NPU1B or NPU1C occupies one slot. One or two PFU1 are fitted in dedicated slots at the left hand side of the AMM. The AMM20pB -10R4 Kit delivery with 10 available slots comprises:One assembled AMM20pTwo Rack Screw KitsOne DC Connector KitOne Earthing Cable, 1mOne NPU1B, or One NPU1COne RMMOne Cable Shelf, an additional cable shelf can be used when routing many cables.One PFU1, one additional PFU1 Kit is needed for redundancyOne Fan Alarm CableNote: Power Input for all magazines is -48v, this tells in the breaker each power cable should be terminated.
8 The Node Processor Unit (NPU) An NPU provides the main control system functions and holds a Removable Memory Module (RMM) for storage of license and configuration information. In addition to this, it provides some traffic handling functions and interfaces, but which ones are depending on type of NPU. The different types are:NPU1 B: used for AMM 20p B provides user I/O interfaces, eight unstructured E1 interfaces, an Ethernet interface for Site LAN, and a USB port for local management.NPU1 C: used for AMM 20p B provides User I/O interfaces, eight unstructured E1 interfaces, one combined Ethernet Site LAN/traffic interface and one Ethernet Traffic interface, two Ethernet SFP interfaces, and a USB port for local management. It contains a non-blocking gigabit Ethernet switch. The switch is a managed VLAN switch (IEEE 802.1Q and IEEE 802.1D) and HW prepared for Provider Bridge switching (IEEE 802.1ad).NPU3: for AMM 2p, 6p C, and 6p D, provides four unstructured E1 interfaces, one Ethernet Site LAN and one Ethernet Traffic interfaces, two User Outputs, and one USB port for local management.NPU3 B: Provides four Unstructured E1 interfaces, one combined Ethernet Site LAN/traffic interface and one Ethernet Traffic interface, two User outputs, and one USB port for local management. It contains a non-blocking gigabit Ethernet switch. The switch is a managed VLAN switch and HW prepared for provider bridge switching.NPU3 C: Provides four unstructured E1 interfaces, one combined Ethernet Site LAN/traffic interface and one Ethernet Traffic interfaces, two User Outputs, and one USB Port local management. It contains a non-blocking gigabit Ethernet switch. The switch is a managed VLAN switch and HW prepared for provider bridge switching. The NPU3 C supports Synchronous Ethernet.
9 Modem Unit (MMU)The MMU is the indoor interface with the radio unit. One MMU is required per radio unit.Note: Before you slot in your MMU, make sure you have Connected your IF cable properly.
