Features:
- Links the Series Six CPU with its primary I/O chain.
- Coordinates supported programmer and data-processor transfers.
- Separates chain, parity, output-enable, and DPU conditions with four indicators.
IC600CB527 occupies the control point between processor execution and the main Series Six I/O path.
Its indications summarize conditions that can originate locally or in connected receivers, cables, and racks.
Effective service starts with the saved topology and jumper record rather than an immediate board exchange.

Trace the main I/O path end to end
- I/O chain: Identify the first receiver, every downstream rack, the total cable route, and the power source at each station connected through IC600CB527.
- Parity response: A continuity or parity symptom can be propagated from remote hardware.
- Indicator meaning: Capture which indicators change before disconnecting any segment.
- Staged restart: Reconnect and test the chain in controlled stages after service.
Preserve the configured CPU response
- Jumper settings: IC600CB527 jumper choices determine how the CPU handles selected peripheral or communication-window failures.
- Setting capture: Photograph and transcribe those positions before removal.
- Configuration record: Do not copy settings from a spare that came from a different machine.
- Fault response: Verify the resulting alarm and STOP behavior during a safe commissioning test.
Check the programmer and data path separately
- Program record: The peripheral connector supports the supported programming or data-processing equipment.
- I/O continuity: A failure here can exist while the primary I/O chain remains healthy.
- Cable path: Inspect cable orientation, connector hardware, and the configured DPU presence before replacing IC600CB527.
- External connection: Prove the peripheral transfer with a known operation after the CPU is stable.
Use all four lamps before isolating the fault
- Parity response: CHAIN OK, PARITY, ENABLED, and DPU describe different parts of the IC600CB527 environment.
- Fault evidence: Record the pattern with the system in its failed state, then compare it with downstream power and receiver indications.
- Operational effect: Avoid clearing evidence by cycling power too early.
- Output control: Enable outputs only after continuity and the actual point map have been confirmed.
