Failure to comply with these precautions or with specific warnings elsewhere in this manual could result in personal injury or damage to the equipment. The safety precautions listed below represent warnings of certain dangers of which Emerson is aware. You, as the user of the product, should follow these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment. Ground the Instrument. To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into an approved three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable meet International Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes. Do Not Operate in an Explosive Atmosphere. Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes. Operation of any electrical equipment in such an environment could result in an explosion and cause injury or damage. Keep Away From Live Circuits Inside the Equipment. Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other qualified service personnel may remove equipment covers for internal subassembly or component replacement or any internal adjustment. Service personnel should not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such personnel should always disconnect power and discharge circuits before touching components. Use Caution When Exposing or Handling a CRT. Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling of a CRT should be done only by qualified service personnel using approved safety mask and gloves. Do Not Substitute Parts or Modify Equipment. Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local Emerson representative for service and repair to ensure that all safety features are maintained. Observe Warnings in Manual. Warnings, such as the example below, precede potentially dangerous procedures throughout this manual. Instructions contained in the warnings must be followed. You should also employ all other safety precautions which you deem necessary for the operation of the equipment in your operating environment.

IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) xiii About This Manual xiv IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 1 Product Features 1 The IPMC712 and IPMC761 are optional modules that provide backward compatibility with earlier Emerson products using the MVME761 or MVME712M rear transition modules. General Functionality Both models are designed around a PMC form factor and both modules incorporate a PCI-toISA bridge, Ultra-wide SCSI adapter, and Super I/O functionality. Both modules are single wide, standard length, standard height PMC boards. They attach to the host board PCI bus via the PMC P11, P12, P13, P14, and P15 connectors. ■ One single-ended ultra-wide SCSI port ■ One parallel port ■ Four serial ports (2 or 3 asynchronous and 1 or 2 synchronous/asynchronous, depending on the module) With this PMC card configuration, the memory mezzanine, one PMC slot, and the PMCspan are still available, providing support for additional product customization. IPMC Mode In IPMC mode, the MVME 6100, MVME5500, and MVME5100 support legacy MVME761 or MVME712M rear transition modules (with limited PMC I/O) when an IPMC712 or IPMC761 module is installed in PMC slot 1. In this configuration, signals used by wide (16-bit SCSI conflict with signals that are used by PMC slot 2 rear I/O. Design Features The following sections describe the basic features that are incorporated in the design of both IPMC modules. PCI Bus Interface Both modules contain four EIA-E700 AAAB connectors, which provide a 32-bit PCI interface to an IEEE P1386.1 PMC-compliant host board such as the MVME6100, MVME5500, or MVME5100. Connectors P11-P13 on each module provide the 32-bit PCI interface while P14 provides an I/O path from the module to the host board. IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 1 Chapter 1 Product Features Signals routed to P14 include: narrow SCSI, parallel port, COM1 and COM2 synchronous serial ports, COM3 and COM4 synchronous serial ports, power, and P2 mux signals. The remaining SCSI data lines are routed to P15. The on-board PCI devices on each module are as follows: ■ Winbond PCI-to-ISA Bridge (PIB) ■ LSI SCSI device (SYM53C895A) Configurable Switches S1 Switch A 1x4 switch (S1) is provided on each module for configuring GPIO pins 2 and 3. The factory default setting is for Ultra-Speed and Ultra-Wide SCSI. Refer to Table 3-1 on page 16 for the GPIO pin assignments and to Figure 3-1 on page 16 for the default switch settings. S2 Switch There is a 1x2 switch (S2) on each module that is in line with the PCI-to-ISA bridge for selecting either AD[11] IDSEL or IDSELB for connection to the Winbond chip, depending on the IPMC module you are using. Note The S2 is not dependent on either IPMC module. It is dependent on either the MVME5100, MVME5500, or MVME6100 host board. The IPMC modules are shipped configured for these boards. Details on IDSEL mapping and PCI arbitration assignments for these SBCs can be found in Chapter 3, Programming. An illustration showing the S2 switch settings can be found in Figure 3-2 on page 17. PCI-to-ISA Bridge (PIB) The PIB provides the bridging functions between PCI local bus and the ISA local resource bus. The following are a few of the features of the PIB. SCSI The SCSI controller is an LSI Logic SYM53C895A device. The SCSI clock frequency is 40 MHz. The SCSI controller features: ■ 32-bit PCI Interface with 64-bit addressing ■ 8KB internal SCRIPTS RAM ■ Improved PCI caching design (improves PCI bus efficiency) The SCSI device maintains backward compatibility with the MVME761 rear transition module and P2 adapter card. It is also Ultra-wide capable and has a performance of 40MB/s synchronous transfer rate across a 16-bit bus. 2 IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) Chapter 1 Product Features Note SCSI signals leading to connector P15 go through zero ohm resistors (R92-R100) before terminating at P15. When the host board’s PMC slot 2 is populated, and there is an IPMC module in slot 1, there exists a possibility for contention on these signals. Figure 1-1.

These registers are also accessible from the PCI bus. Super I/O The Super I/O device (PC97307) provides the following functions on the IPMC: ■ Two synchronous serial ports (COM1 and COM2) ■ Parallel printer port ESCC Two DTE synchronous/asynchronous serial ports are provided by the ESCC device (Z85230). Since the Z85230 device does not have all modem control lines, a Z8536 CIO device (described below) is used to provide the missing lines. A PAL device is used to perform decode for the Z85230 and the Z8536 for register accesses and pseudo interrupt acknowledge cycles in the ISA I/O space. DMA supports for the Z85230 is provided by the PIB. The clock input to the Z85230 PCLK pin is a 10 MHz clock. The Z85230 supplies an interrupt vector during a pseudo interrupt acknowledge cycle. The vector is modified based upon the interrupt source within the device. All modem control lines from the ESCC are multiplexed/demultiplexed through connector P2 by the P2MX function due to pin limitation of the connector. CIO The CIO device (Z8536) is used to provide the modem control lines not provided by the Z85230 ESCC. In addition, the device has three independent 16-bit counters/timers. The clock input to the Z8536 PCLK pin is a 5 MHz clock. Static ROM (SROM) Both modules contains one +3.3V, 256 x 8 serial EEPROM device (AT24C02) onboard. This device provides for Vital Product Data (VPD) storage of the module hardware configuration. The serial EEPROM is located on the baseboard’s I2C bus at address $A4. 8 IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) Chapter 1 Product Features Input/Output Modes Both modules are designed to be plugged into PMC slot 1 of the base board. As stated earlier, these SBCs have two P2 I/O modes (IPMC and PMC) that are user configurable. The user should configure the baseboard for the IPMC module being used. The jumpers route the on-board Ethernet port 2 to row C of connector P2. When used, both modules are backwards compatible with the MVME761 rear transition module and P2 adapter card (excluding PMC I/O routing) used on the MVME2600/2700. The rear panel Ethernet is not available when using the IPMC712. LEDs Both modules use two LEDs to provide PMC status. ■ The module’s green SCSI LED is lit when the SCSI device is Master ■ The module’s green PIB LED is lit when the PCI bus grant to the PIB is asserted PCI Signaling Voltage Level Both modules will operate with only +5V signaling levels. RS232 Interface On the IPMC712 module, the four serial ports are used to communicate at RS232 voltage levels (P14). The first three ports are fixed asynchronous ports, while the remaining port can be configured as either a synchronous or an asynchronous port. For additional handshaking signals, the IPMC712 module has the following features: ■ Port 1 has RTS and CTS ■ Ports 2, 3, and 4 have RTS, CTS, DTR, DCD ■ Port 4 has configurable serial clock signals RTxC and TRxC Jumpers J2, J3 and J5 determine the sources for these two signals, refer to Figure 1-5 on page 7.

For additional information pertaining to the MVME51005E, refer to the information contained in the MVME51005E Single Board Computer Installation and Use manual before proceeding with these instructions contained in this chapter. Packaging As a precautionary measure, IPMC modules are sealed in an anti-static package to protect them from static discharge. Observe standard handling practices of static sensitive equipment. Configuring the IPMC Modules There are two user configurable switches on the IPMC712 and IPMC761 I/O modules. Switches S1 and S2 are described in Chapter 3, Programming. Installing IPMC Modules on Host Board Both the IPMC712 and the IPMC761 modules are installed on PMC slot 1 of the host board. As a general reminder, IPMC modules must be installed on the host board prior to installing it into the VME chassis. To install an IPMC module, refer to the following figure and proceed as follows: 1. Inspect the host board and the IPMC module for evidence of any damage to the PCB itself or for evidence of any damage on the mating connectors. 2. If the host board is installed in a VMEbus card slot, carefully remove it and place it with connectors P1and P2 facing you. IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 11 Chapter 2 Installing the IPMC Module 3. Remove the filler plate from the host board’s front panel. Position the IPMC module over the center area of the slot 1 connectors as follows: Figure 2-1. IPMC Installation 4. Line up the IPMC module’s front panel into the IPMC filler cutout slot on the host board’s front panel. 5. Align connectors P11, P12, P13, P14, and P15 on the IPMC module with the mating connectors on the host board and press firmly into place. 6. Insert the appropriate number of Phillips screws (typically 4) from the bottom of the host board into the standoffs on the IPMC module and tighten the screws. The host board is now ready to be installed into a VME chassis. Before You Install or Remove a Board Boards may be damaged if improperly installed or handled. Please read and follow the guidelines in this section to protect your equipment. Observe ESD Precautions ESD Use ESD Wrist Strap Emerson strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading a system. Electronic components, such as disk drives, computer boards, and memory modules, can be extremely sensitive to electrostatic discharge (ESD). After removing the component from its protective wrapper or from the system, place the component flat on a grounded, static-free surface (and, in the case of a board, component side up). Do not slide the component over any surface. If an ESD station is not available, you can avoid damage resulting from ESD by wearing an antistatic wrist strap (available at electronics stores) that is attached to an active electrical ground. Note that a system chassis may not be grounded if it is unplugged. 12 IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) Chapter 2 Installing the IPMC Module Watch for Bent Pins or Other Damage Caution ! Caution Bent pins or loose components can cause damage to the board, the backplane, or other system components. Carefully inspect your board and the backplane for both pin and component integrity before installation. ECC and our suppliers take significant steps to ensure there are no bent pins on the backplane or connector damage to the boards prior to leaving our factory. Bent pins caused by improper installation or by boards with damaged connectors could void the warranty for the backplane or boards. If a system contains one or more crushed pins, power off the system and contact your local sales representative to schedule delivery of a replacement chassis assembly. Use Caution When Installing or Removing Boards When first installing boards in an empty chassis, we recommend that you start at the left of the card cage and work to the right when cards are vertically aligned; in horizontally aligned cages, work from bottom to top. When inserting or removing a board in a slot adjacent to other boards, use extra caution to avoid damage to the pins and components located on the primary or secondary sides of the boards. Preserve EMI Compliance Caution ! Caution To preserve compliance with applicable standards and regulations for electromagnetic interference (EMI), during operation all front and rear openings on the chassis or board faceplates must be filled with an appropriate card or covered with a filler panel. If the EMI barrier is open, devices may cause or be susceptible to excessive interference. IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 13 Chapter 2 Installing the IPMC Module Recognize Different Injector/Ejector Lever Types The modules you install may have different ejector handles and latching mechanisms. The following illustration shows the typical board ejector handles used with ECC payload cards: (A) Elma Latching, (B) Rittal Type II, (C) Rittal Type IV. All handles are compliant with the CompactPCI specification and are designed to meet the IEEE1101.10 standards. Figure 2-2. Injector/Ejector Lever Types A B C 4243 1103 Each lever type has a latching mechanism to prevent the lever from being opened accidentally. You must press the lever release before you can open the lever. Never force the lever. If the lever does not open easily, you may not have pressed firmly enough on the release. If the lever does not close easily, the board may not be properly seated in the chassis. To open a lever, press the release and move the lever outward away from the faceplate. To close a lever, move the lever inward toward the faceplate until the latch engages. Verify Slot Usage Prevent possible damage to module components by verifying the proper slot usage for your configuration. Caution ! Caution 14 IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 3 Programming 3 Programing Details The overall design of the IPMC712 and IPMC761 is based on the PowerPlus II architecture. The programming characteristics for both modules conforms to the PowerPlusII Programming Specification. Note The PowerPlus II Programming Specification covers a large variety of programming configurations, many of which are not applicable to either module. This chapter describes those aspects of the specification that are unique to both modules. PCI Local Bus The on-board PCI devices on the IPMC712 and the IPMC761 are the PCI-to-ISA Bridge and the SCSI controller. The PCI-to-ISA Bridge (PIB) The PCI-to-ISA Bridge (PIB) provides the bridging functions between PCI local bus and the ISA local resource bus. Other features contained in the PIB are: ■ 8259 Interrupt Controller ■ ISA DMA support ■ Timers and counters The SCSI Controller The SCSI controller’s clock speed is 40 MHz. The presence of the SCSI device can be positively determined by reading the Device ID PCI Configuration Register 0x02 - 0x03. The Device ID is 0x0012. IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 15 Chapter 3 Programming The General Purpose I/O (GPIO) pin assignments for the SCSI Controller are shown in the table below. A 1x4 switch (S1) is provided to configure GPIO pins 2 and 3. The factory default setting shall be for Ultra-Speed and Ultra-Wide SCSI. Table 3-1.

It is important that the settings of P1 and P2 are neither both on nor both off, otherwise the device will be enumerated twice. If Then The SW2-P1 is OFF The W83C553’s IDSEL is connected to IDSELB (P12:34). The IDSEL is then determined by the carrier’s configuration of the IPMC site. The SW2-P2 is OFF The W83C553’s IDSEL is connected to AD11 on the IPMC. The IPMC761-002 is used on an MVME6100 The SW2-P1 should be OFF and SW2-P2 set ON for proper operation. The IPMC761-002 is used on an MVME5100 or MVME5500 The SW2-P1 should be ON and SW2-P2 OFF to emulate the IPMC761-001. IDSEL Address Assignments for PCI Local Bus Legacy IDSEL assignment for the PCI-to-ISA Bridge (PIB) is maintained to ensure software compatibility between MVME2700 and MVME5100 while functioning in IPMC mode. The IPMC712 and IPMC761 boards have a switch (S2) that allows you to configure the board for the correct IDSEL connection to the Winbond chip, as described below: ■ Connection to IDSEL, AD[11] on PMC connector pin P11-48 is selected when using the IPMC 712/761 with ECC VME boards MVME5100 and MVME5500 (boards released prior to the MVME6100) ■ Connection to IDSEL, AD[16] on PMC connector pin P12-34 is selected when using the IPMC712/761 with the MVME6100 board ■ Connection to IDSELB varies according to the base board: – 5100: No Connect – 5500: AD[17] – 6100: AD[21] – PrPMC Carrier: AD[17] IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) 17 Chapter 3 Programming The IDSEL assignments for both modules are shown below: Table 3-3.

MVME5100 The MVME5100 PCI arbitration is performed by the Hawk ASIC on the host board which supports eight external PCI masters. Included is the Hawk itself and seven external PCI masters. The arbitration assignments for the IPMC712 and IPMC761, when installed on the MVME5100, are as follows: Table 3-5. PCI Arbitration Assignments PCI Bus Request PCI Master(s) Request 1 (PARBI1) PMC Slot 1 (SCSI device on the module in PMC Slot 1) Request 2 (PARBI2) PIB device on the module in PMC Slot 1 MVME5500 The MVME5500 IPMC module PCI arbitration is performed using logic implemented in Programmable Logic Devices (PLDs). These arbiters use a rotating priority scheme for fairness and bus parking and will always be on the GT-64260B. There are no software programmable modes to these arbiters. 18 IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) Chapter 3 Programming MVME6100 The MVME6100 IPMC module PCI arbitration is performed by the MV64360 ASIC. The internal PCI arbiter REQ#/GNT# signals are multiplexed on the MV64360 MPP[31:0] pins. The internal PCI arbiter is disabled by default (the MPP pins function as general purpose inputs). Software will configure the MPP pins to function as request/grant pairs for the internal PCI arbiter. The IPMC module arbitration pairs for the MVME6100 are assigned to the MPP pins as follows; ■ MPP pin 8, PCI Bus Grant (PIB device on IPMC module) ■ MPP pin 9, PCI Bus Request (PIB device on IPMC module) ■ MPP pin 12, PCI Bus Grant (SCSI device on IPMC module) ■ MPP pin 13, PCI Bus Request (SCSI device on IPMC module) Interrupt Assignments The interrupt architecture for the IPMC712 and IPMC761 is fully compliant with the PowerPlusII Programming Specification for a single processor board configuration. MVME5100 IPMC Module Interrupt Assignments Legacy interrupt assignment for the PCI-to-ISA Bridge (PIB) is maintained to ensure software compatibility between MVME5100 and IPMC761 while in IPMC mode. This is accomplished by using the on-board IPMC761 connector to route the PIB’s interrupt to external interrupt 0 of the Hawk’s MPIC. The MVME5100 Ethernet port 2 is routed to the PIB’s IRQ10 input. The SCSI interrupt on the IPMC761 is also routed to the PIB at IRQ14. The SCSI device is connected to the INTA# pin J11-04 of PMC Slot 1. Interrupts are routed to the Hawk from on-board resources as specified by the module’s programming. The Hawk interrupt assignments are shown below: Table 3-6.

MVME5100 Hawk MPIC IRQ9 interrupt sources may be one of the following: PCI-PMC1 INTA#, PMC2 INTB#, or PCIX INTA#. MVME5500 IPMC Module Interrupt Assignments Legacy Interrupt assignments were not maintained on the MVME5500 due to the vastly different host bridge device (GT-64260) used. The MVME5500 uses the GT-64260 interrupt controller to handle interrupts internal to the GT-64260 as well as the external interrupt sources. The GT-64260 us's general purpose pins that are configured by software to act as interrupt inputs. The following are the IPMC module-related interrupt assignments. GPP PIN Edge/Level Polarity Interrupt Source 11 Level Low IPMC PIB (8259) Int in Slot 1 8 Level Low SCSI Controller Interrupt Connected to INTA# pin J11-04 Note The MVME5500 does not have any Ethernet interrupts routed back to the IPMC PIB device. MVME6100 IPMC Module Interrupt Assignments Legacy Interrupt assignments were not maintained on the MVME6100 because of the vastly different host bridge device (MV64360). The MVME6100 uses the interrupt controller integrated into MV64360 to manage the MV64360 internal interrupts as well as the external interrupt requests. The IPMC module interrupts are routed to the MV64360 MPP pins as follows; GPP PIN Edge/Level Polarity Interrupt Source 5 Level High IPMC PIB (8259) Int in Slot 1 16 Level Low SCSI Controller Interrupt Connected to INTA# pin J11-04 Note The MVME6100 does not have any Ethernet interrupts routed back to the IPMC PIB device. ISA Local Resource Bus The ISA devices on the IPMC712 and IPMC761 are as follows: 20 ■ PCI-to-ISA Bridge ■ Super I/O IPMC7126E/7616E I/O Module Installation and Use (6806800A45B) Chapter 3 Programming PCI-to-ISA Bridge (PIB) The PIB contains ISA Bridge I/O Registers for various functions. These registers are accessible from the PCI bus. Super I/O The Super I/O device provides the following functions: ■ Two serial ports (asynchronous) ■ Parallel port interface The device’s hardware configuration is based on two strap-pins: BADDR0 and BADDR1. During reset, strapping options shown on BADDR0 and BADDR1 pins determine the device’s operation. Clock speed is 48 MHz.The following table shows the hardware strapping for the Super I/O device: Table 3-7.

Internally generated by the PIB. 2. After a reset, all ISA IRQ interrupt lines default to edge-sensitive mode. 3. Interrupts from the Z8536 and Z85230 devices are externally wired. External logic will determine which device to acknowledge during a pseudo IACK cycle. The Z8536 CIO has higher priority than the Z85230 ESCC. This IRQ MUST be programmed for level-sensitive mode. 4. This interrupt is routed from the MVME5100 through the IPMC connector to the module’s PIB to allow backward compatibility to other products.
