Obsolescence & Supply Chain Deep Dive

The GE IS215UCCH4A reference corresponds to the legacy Mark VIe UCCC controller family, but GE’s published Mark VIe hardware documentation identifies the processor board as IS215UCCCH4 and the commonly documented complete controller assembly as IS215UCCCM04. The UCCC processor uses a 1.6 GHz Intel Pentium M processor, 256 MB DDR SDRAM and two 10/100/1000Base-TX Ethernet ports. The processor board is installed in a single CPCI slot and works with the IS200EPMC controller-function PMC.

This is a controller-level spare, so substitution should not be evaluated like an ordinary I/O card. The controller contains the processing environment for the Mark VIe application, and the installed CompactFlash/software configuration can be essential to restoring the original control application. GE’s replacement procedure specifically addresses transferring the CompactFlash from the failed controller when it remains functional, followed by controller configuration and ToolboxST verification. For a plant with a legacy Mark VIe installation, a correctly identified processor spare can therefore reduce the engineering scope associated with migrating the complete control platform.

Compatibility & Replacement Matrix

Field Traps — Watch Out

The missing “C” is a procurement risk.
Your supplied number is IS215UCCH4A, while GE documentation identifies the UCCC processor board as IS215UCCCH4 and supplier records commonly list IS215UCCCH4A. Do not normalize the number automatically. Compare the complete nameplate, board label and installed documentation before issuing a PO.

Do not confuse the processor board with the complete controller assembly.
The documented IS215UCCCH4 is the processor board, while IS215UCCCM04 is a module assembly incorporating the processor board, flash memory, DRAM and IS200EPMC. These are related but should not be treated as identical catalog numbers.

CompactFlash configuration matters.
GE’s replacement procedure specifically instructs technicians to transfer the CompactFlash from the old controller when it is still functional. A replacement controller without the correct application image may therefore require a software download before it returns to the controlling state.

Quality Assurance & Testing SOP

A UCCC controller should be tested as a complete computing assembly rather than judged only by visual condition.

Identity and physical inspection

• Verify the complete board nameplate
• Confirm whether the marking is IS215UCCH4A or IS215UCCCH4A
• Record serial number and hardware revision
• Inspect CPCI backplane connectors
• Check injector/ejector mechanisms
• Inspect Ethernet connectors
• Inspect PMC sites
• Check LEDs and front-panel labeling
• Inspect PCB components for corrosion, contamination or physical damage
• Photograph all identification markings

Power-on and POST testing

• Install the controller in a suitable Mark VIe CPCI test enclosure
• Verify required backplane power
• Confirm normal startup
• Check BIOS/POST behavior
• Verify processor identification
• Verify memory recognition
• Check CompactFlash detection
• Confirm controller status LEDs
• Verify that the board reaches the expected operating state

The published UCCC specifications identify the processor as a 1.6 GHz Intel Pentium M, with 256 MB DDR SDRAM, 128 MB CompactFlash in the documented UCCCM04 assembly, and QNX Neutrino as the operating system.

Ethernet verification

• Test Ethernet port 1
• Test Ethernet port 2
• Verify link establishment
• Verify 10/100/1000Base-TX operation as applicable
• Confirm network communication
• Check port activity
• Verify the applicable Unit Data Highway connection
• Check the optional network interface where configured

Controller and software verification

• Verify controller recognition in the Mark VIe environment
• Confirm ToolboxST communication
• Verify controller IP configuration
• Confirm application download capability
• Check controller operating state
• Verify no persistent startup diagnostics
• Confirm synchronization/network status where applicable

GE’s documented replacement sequence includes reconnecting IONet and VLAN connections, configuring TCP/IP when required, and using ToolboxST to confirm that the replacement controller reaches the controlling state without warnings or errors.

Final release inspection

• Record serial number
• Record hardware revision
• Record processor and memory configuration
• Document Ethernet test results
• Document CompactFlash status
• Photograph the tested unit
• Apply ESD protection
• Protect CPCI connectors during transportation
• Use shock-resistant export packaging

Procurement & Lifecycle FAQ

What is the GE IS215UCCH4A?

The supplied IS215UCCH4A reference appears to correspond to the GE Mark VIe UCCC controller family. GE documentation identifies the UCCC processor board as IS215UCCCH4, while current industrial supplier records commonly identify the complete board as IS215UCCCH4A. The exact nameplate should control procurement.

What processor does the UCCC controller use?

The documented UCCC processor board uses a 1.6 GHz Intel Pentium M processor. The published specification identifies 256 MB DDR SDRAM and QNX Neutrino as part of the UCCC controller architecture.

How many Ethernet ports does the UCCC processor have?

The documented IS215UCCCH4 UCCC processor provides two 10/100/1000Base-TX Ethernet ports. These support the controller’s network connectivity within the Mark VIe architecture.

Is the same as IS215UCCCM04?

No. The documented IS215UCCCH4 is the UCCC processor board, while IS215UCCCM04 is a module assembly that combines the UCCC processor with memory and the IS200EPMC PMC. The two identifiers should remain separate in purchasing and inventory records.

What should be confirmed before purchasing this controller?

Confirm the complete physical nameplate, especially the distinction between and , plus hardware revision, serial number, CompactFlash configuration, EPMC configuration, installed Mark VIe software version and network configuration. For a shutdown-critical spare, request serial-specific photographs and documented power-on, POST, Ethernet and controller-status testing before shipment.
