Functional Overview Functional Overview 2 Rear Transition Modules (RTM) are important components in many telecommunications and embedded systems. These environments place most of the active components on a Front Board and most of the cable connections (especially copper cables) are made from the RTM. This allows the Front Board to be replaced without the need to reinsert a large number of cables in the correct order. In AdvancedTCA* systems, the Front Board mates directly with the RTM, as s

Functional Overview • One SAS x4 connector to support external SAS JBOD. (Only three of these SAS ports on the RTM are usable; the first SAS port is used by the MPCBL0020 Single Board Computer’s local SAS drive.) • Six T1/E1 ports with transformer and protection circuitry (designed primarily for intra- building applications) 2 • I C connectivity to the SBC for remote management capabilities • OOS and Health LEDs • Hot Swap status LED. This LED mirrors the indication of the HS status LED on the

Operating the Unit Operating the Unit 3 3.1 Introduction ® The Intel NetStructure MPRTM0020 Rear Transition Module is a non-intelligent RTM. A non- intelligent FRU does not have a remote management controller (RMC) on board to communicate with the SBC IPMC. Instead, all of the non-intelligent RTM sensors and FRU device information is 2 made available to the IPMC through direct device access. This is usually done via dummy I C sensor and storage devices. It is the responsibility of the IPMC to

Operating the Unit 3.4 Digital Ground to Chassis Ground Connection Digital ground can be tied to chassis ground through a jumper (P2) located near the bottom, right corner of the RTM. In the default grounding for the MPRTM0020, digital ground is isolated from chassis ground (jumper link connecting “NC” to “GND”) as shown in Figure 2. Figure 2. Default Grounding on MPRTM0020 To connect the digital ground to the chassis ground, follow this procedure: 1. Remove the jumper link from the default lo

Module Components 4.3 Components Description The following sections describe the components shown in Figure 4 through Figure 6. 4.3.1 Serial Port Interface One serial port (RS-232) connector is present on the RTM. This connector provides access to the COM1 serial port from the MPCBL0020 Single Board Computer, which is also routed to the front panel of the SBC. Both connections are active, but only one can be used at any given time. The line driver/receiver for the serial port resides on the SB
