SECTION 1 - INTRODUCTION OVERVIEW The IEMMU11, IEMMU12, IEMMU21, and IEMMU22 are mod- ule mounting units used to house standard INFI 90 OPEN sys- tem modules and the BRC-100 Harmony Bridge Controller module of the Symphony system in system cabinets. NOTE: IEMMU11, IEMMU12, IEMMU21, and IEMMU22 Module Mounting Units can be used as replacements for IEMMU01 and IEMMU02 Module Mounting Units. They can also be installed along with IEMMU01 and IEMMU02 units; however, transition board assemblies are required for interconnection between IEMMU11, IEMMU12, IEMMU21, or IEMMU22 units and IEMMU01 or IEMMU02 units. The module mounting unit consists of a sheet metal card chas- sis and a printed circuit board backplane assembly. The open top and bottom structure allow air to flow over the modules. Mounting flanges are provided for mounting the mounting unit in a standard Elsag Bailey 483-millimeter (19-inch) cabinet. Modules can be installed and removed quickly and easily. The module is held in position by card guides, the connectors on the backplane, and the module’s front panel, captive fastening latches. The backplane is a multilayer printed circuit board assembly containing electronic components, dipshunt sockets, connec- tors, and jumpers. In most cases, the mounting unit provides direct I/O cable coupling to the modules. The exception to this is when a BRC-100 Harmony Bridge Controller module is installed in the MMU. Refer to PROCESSOR BUS ADAPTER BRACKETS INSTALLATION in Section 3 for further explana- tion. IEMMU11 and IEMMU12 Module Mounting Units The IEMMU11 and IEMMU12 module mounting units provide physical mounting for up to 12 system modules or ten system modules and a maximum of two IEPAS02, IEPDS01/02, IEPAF02, and IEPDF01/02 power modules. They also provide electrical distribution of I/O expander bus, module bus, and Controlway signals; distribution of regulated power supply voltages (+5 volts, +15 volts, –15 volts and 24 volts); and distri- bution of primary power. Primary power is the 120/240 VAC or 24/48 VDC that sup- plies power to power modules (IEPAS02, IEPAF02, IEPDS01, IEPDF01, IEPDS02 and IEPDF02) that can be mounted in the OVERVIEW WBPEEUI200501B0 1 - 1 ® INTRODUCTION mounting units. Typically, systems that use IEPMU01/02 do not use distributed primary power to the mounting units. Sys- tems that use Modular Power System II do not allow distrib- uted primary power to the mounting units. The IEMMU11 module mounting unit is used when the cabinet configuration requires a rear mount chassis with primary power distribution. The IEMMU12 module mounting unit is used when the cabinet configuration requires a front mount chassis with primary power distribution. IEMMU21 and IEMMU22 Module Mounting Units The IEMMU21 and IEMMU22 module mounting units provide physical mounting for up to 12 system modules; provide elec- trical distribution of I/O expander bus, module bus, and Con- trolway signals; and distribution of regulated power supply voltages (+5 V, +15 V, and –15 V). The IEMMU21/22 module mounting units are the preferred choice for use with Modular Power System II. The IEMMU21 module mounting unit is used when the cabinet configuration requires a rear mount chassis with no primary power distribution. The IEMMU22 mounting unit is used when the cabinet config- uration requires a front mount chassis with no primary power distribution. IEMMU01 AND IEMMU02 REPLACEMENT The IEMMU11, IEMMU12, IEMMU21, and IEMMU22 units are functional equivalents to existing IEMMU01 and IEMMU02 units. The I/O expander bus interconnect cables are different however. The new module mounting units utilize a grey ribbon cable (refer to Table 5-1 for part number) to connect I/O expander bus between adjacent units. This cable replaces the amber colored interconnect cable used on the IEMMU01 or IEMMU02 unit. IEMMU01 AND IEMMU02 CONNECTION A transition board (refer to Table 5-3 for part number) is needed if an IEMMU11, IEMMU12, IEMMU21, or IEMMU22 unit is to be connected to an IEMMU01 or IEMMU02 unit. The amber color interconnect cable connects from the IEMMU01 or IEMMU02 unit to the transition board plugged into the IEMMU11, IEMMU12, IEMMU21, or IEMMU22 unit back- plane. Refer to TRANSITION BOARD INSTALLATION in Section 3 for details. IEMMU01 AND IEMMU02 REPLACEMENT 1 - 2 WBPEEUI200501B0 INTRODUCTION INTENDED USER Personnel installing, operating, or maintaining the mounting units should read this manual before performing any installa- tion, maintenance or replacement procedures. Installation requires an engineer or technician with experience in handling electronic circuitry. FEATURES The backplane in these mounting units has several features: • I/O expander bus interconnect cables based on 2.54-milli- meter (0.1-inch) center ribbon cable technology for enhanced robustness. Cables come in choice of two lengths: 38 millimeter (1.5 inches) and 171 millimeter (6.75 inches). • Ability to segment Controlway or module bus into three segments on the backplane, which provides for increased density and lower costs. • Available with or without primary power distribution. Mod- ule mounting unit with primary power distribution is only needed for AC and DC Modular Power Systems configured for primary power distribution.
