Information
- The Petra II controller combines a 68060 CPU with storage, communications and IndustryPack expansion for an installed VME application.
SCSI check: record IDs and termination
Daughtercard check: label both IP positions
After exchange: prove each used interface
The MVME172P2 platform routes serial, SCSI, Ethernet and IndustryPack signals through defined front and backplane connections. Confirm the actual transition module and fitted IndustryPack cards before treating a spare controller as interchangeable in a populated chassis.
The board carries battery-backed working data and firmware used during startup. Capture the boot route, operating software and network settings before exchange; after installation, validate interface discovery and the connected application, not just a successful firmware prompt.

Motorola MVME172PA-652SE technical reference
Prepared by Apter Power - PDF, 4 pages. Motorola MVME172P2 VME Embedded Controller with 2 IP Slots, 172IP-D2; MVME172P2 Installation and Use, V172P2A/IH. -
Motorola MVME172PA-652SE installation guide
Prepared by Apter Power - PDF, 3 pages. Model-specific installation, electrical checks and commissioning review.
Peripheral boundary: IndustryPack I/O and rear cable access depend on fitted cards and transition hardware; neither is implied by the base-board order row.
-
Legacy VME control
Retain a compatible 68060 software environment and VME address map when replacing the embedded controller. -
SCSI device access
Connect the documented storage path through the installed transition hardware and verify device addressing and termination. -
Ethernet communication
Restore interface address and network configuration before proving controller-to-host traffic. -
IndustryPack functions
Match the fitted IP modules and their channel wiring to the two available positions before application checkout.
Isolate the VME supply and use board-level ESD protection before handling the controller or IndustryPacks.
Record cable orientation, device IDs and bus termination before moving storage connections.
Identify the correct front or transition-module connector before reusing an existing network cable.
Document slot positions and daughtercard wiring, then inspect mechanical seating after transfer.
Back up application and firmware settings that depend on nonvolatile or battery-backed storage.
Check boot diagnostics, SCSI discovery, Ethernet traffic and each populated IP signal path against the original system record.

Technical notes
Installed options: The PA-652SE ordering row confirms SCSI and Ethernet. Match each connection to the rear transition arrangement before transferring cables.
Memory and startup: Preserve the boot image and recorded SDRAM configuration. Battery-backed data can affect startup and field application settings.
Technical reference: Motorola MVME172P2 VME Embedded Controller with 2 IP Slots, 172IP-D2, and MVME172P2 Installation and Use. The ordering row identifies this exact Petra II configuration.
FAQ View All FAQ
-
How is MVME172PA-652SE distinguished from the MVME172-333 controller?The PA-652SE ordering row specifies 60 MHz MC68060 with 32 MB SDRAM and the Petra II two-IndustryPack architecture; the LX-333 is a different controller with 8 MB ECC DRAM.
-
What must be checked before reusing a SCSI cable with MVME172PA-652SE?Confirm the installed transition path, SCSI ID assignments and termination at both bus ends; a present connector does not validate a storage chain.
-
How should Ethernet startup be verified on MVME172PA-652SE?Check link, board firmware interface selection, assigned address and successful traffic to the intended host, then test the application protocol.
-
What influences IndustryPack compatibility on MVME172PA-652SE?The board exposes two IP positions, but function and field pinout come from the populated daughtercards and the system wiring. Compare both card identities before exchange.
-
Why should battery-backed data be captured before replacing MVME172PA-652SE?Stored clock, NVRAM or working configuration may participate in startup. Record and back up the original values so a cleared replacement is not mistaken for a hardware fault.
-
What would explain a boot device missing after MVME172PA-652SE replacement?Inspect SCSI routing, device IDs, termination and firmware boot parameters before concluding that the processor board has failed.
-
How should a 68060 software image be assessed for MVME172PA-652SE?Verify the existing operating-system build and board support package against the PA-652SE CPU, memory map and attached interfaces; do not assume a different MVME172 variant is binary-equivalent.
-
Which checks complete acceptance of MVME172PA-652SE?Confirm firmware startup, SDRAM test, SCSI and Ethernet communication, then exercise each fitted IndustryPack channel with the application and record the result.
