More Information

Overview Manuals Carrier Fit PMC Integration Legacy Support Product Applications

Features:

  • Dual PMC expansion: Two mezzanine sites extend compatible VMEbus processor assemblies.
  • Host-specific carrier: Official documentation identifies the supported XVME processor families.
  • Installed-base service role: Retired status places configuration capture ahead of board exchange.
XVME-976 is useful when a legacy XVME system depends on PMC functions that must remain in the existing VMEbus chassis.

A carrier-only replacement still affects mezzanine seating, rear-I/O routing, thermal load and software enumeration.

Service planning therefore records the complete processor, carrier and PMC assembly before any board is removed.

Apter Power can help confirm the Xycom XVME-976 Dual PMC Carrier Module, board suffix, host processor, installed mezzanines and legacy-system recovery scope before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Host identity: Confirm the processor is an officially documented XVME-689 or XVME-690 family member.
  • Slot clearance: Check adjacent cards, retainers and cable access for the populated carrier.
  • Power demand: Add both PMC loads to the processor and chassis power budget.
  • Cooling path: Preserve airflow across the carrier and installed mezzanines.
  • Site record: Photograph and label each PMC position before disassembly.
  • Rear I/O: Confirm whether either mezzanine depends on P2 or chassis transition hardware.
  • ESD handling: Use grounded controls while moving the carrier and PMC boards.
  • Software check: Verify that every mezzanine enumerates and its driver loads after restart.
  • Configuration archive: Retain BIOS, operating-system and application records with the hardware map.
  • Spare screening: Match the exact carrier family and inspect connectors before installation.
  • Bench strategy: Use a compatible controlled system rather than an undocumented standalone power test.
  • Migration trigger: Escalate when host, PMC or driver support can no longer be sustained.
  • Industrial VME computers: Hosts PMC interfaces in supported XVME processor systems.
  • Test equipment: Preserves specialized mezzanine functions in legacy instrumentation.
  • Machine-control platforms: Maintains an installed processor and I/O combination during service.
  • Migration preparation: Provides a verified hardware map for replacement-system design.
Description
XVME-976 expands compatible Xycom VMEbus processor systems with two PMC carrier sites, allowing approved mezzanine functions to be integrated without replacing the processor board.

The host relationship of XVME-976 is specific: official documentation ties it to XVME-689 and XVME-690 systems. Carrier power, PMC height, rear-I/O use and slot clearance must be reviewed as one assembly.

Because XVME-976 is retired, a service replacement should preserve the board suffix, host processor, installed PMC identities and backplane arrangement. Functional acceptance includes enumeration and application tests for every fitted mezzanine.

Technical notes
XVME-976 is retired VMEbus hardware intended for documented XVME-689 and XVME-690 host systems. Remove rack power and observe ESD controls before handling. Record carrier suffix, PMC positions, rear-I/O use and slot assignment. Stop installation if host compatibility, mezzanine power demand or mechanical clearance cannot be confirmed from the installed assembly.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can XVME-976 be installed in any 6U VMEbus computer?
No. The official catalog associates XVME-976 with XVME-689 and XVME-690 processor systems, so other hosts require documented engineering compatibility rather than form-factor assumptions.
What should a technician record before moving PMC cards from XVME-976?
Record each mezzanine identity, carrier site, orientation, rear-I/O connection and cable route. Preserve ESD controls and keep the original arrangement available for comparison.
Why might a system boot after replacing XVME-976 while one function remains unavailable?
The carrier can be present while a PMC card, rear-I/O path or software driver is missing. Check enumeration and application diagnostics for each mezzanine separately.
Can two populated XVME-976 carriers be added without reviewing chassis power?
No. Include the host boards and every PMC load in the chassis power and cooling review before changing the installed configuration.
How should a spare XVME-976 be screened before a short outage?
Confirm the full ordering identity, connector condition and host fit, then plan a controlled in-system test that exercises each intended PMC function without bypassing machine safeguards.
When should an owner migrate away from XVME-976?
Plan migration when compatible hosts, mezzanines, drivers or verified spares cannot meet the site support horizon. Preserve the existing hardware and software map as the redesign baseline.
