Product Precautions
- LCN node recovery depends on retaining the processor identity, address selection and host configuration around K2LCN-8 51401551-801.
Function: K2LCN node processing
Address selection: TS2 at board coordinate 9C
Configuration: Matched processor, memory and host I/O
Address selection: TS2 at board coordinate 9C
Configuration: Matched processor, memory and host I/O
K2LCN provides the LCN-side processing function in the WDA History Module architecture. The module also uses a separate Smart Peripheral Controller and drive-interface hardware for its storage path. The complete 51401551-801 ordering identity must be retained when matching the K2LCN-8 configuration. Memory capacity, installed firmware and host software requirements must be reconciled against the actual board and node configuration.
The TS2 address block is located at board coordinate 9C. Its seven weighted positions represent 1 through 64 in binary weighting. Removing a jumper sets a binary 1, and the total count of removed positions, including parity, must be odd. Preserve the installed node address rather than copying an example setting.
The LCN address can be selected on the processor or on the associated LCN I/O board, with only one location active. The unused selection must be neutralized according to its jumper or switch implementation. In the WDA History Module, the processor occupies front slot 1 and the matching I/O board sits in the rear card cage; mechanical compliance, memory and software configuration must remain compatible.

-
History-node processing
Maintain the configured LCN node processing path used by the host History Module; disks and peripheral controllers remain separate assemblies. -
Network addressing
Retain the assigned LCN address and the single active address-selection location in the installed node. -
Host restoration
Match the processor board, memory arrangement, I/O board and software personality before restoring the node. -
Controlled maintenance
Record the existing jumpers and host configuration, then verify node communication after replacement.
Prepare K2LCN-8 51401551-801 against the installed configuration and applicable Honeywell instructions. Plan isolation and the resulting interruption of system operation before replacement.
Preserve complete identity
Match the full part number, board revision and installed node personality before replacement.
Record address configuration
Record all binary address and parity positions before removing the original board.
Use one address location
Select the address on one approved board only; neutralize the unused selection location as specified for that hardware.
Match memory hardware
Confirm the required memory assembly separately; do not infer supplied memory from a related processor designation.
Isolate and protect
Follow the host shutdown procedure and electrostatic handling controls before extraction.
Verify node recovery
Check node identity, network communication and intended host services before returning the system to normal operation.

FAQ View All FAQ
-
What role does K2LCN-8 51401551-801 perform?It is a K2LCN node processor board. In the WDA History Module, it handles the LCN-side processing path while the SPC and disk hardware perform separate peripheral functions.
-
Where is the address block on K2LCN-8 51401551-801?The applicable board design uses TS2 at coordinate 9C. Confirm the printed assembly marking and actual board layout before moving jumpers.
-
What does a removed address jumper mean on K2LCN-8 51401551-801?A removed jumper represents binary 1. The weighted address positions are 1, 2, 4, 8, 16, 32 and 64.
-
What parity rule applies to address selection on K2LCN-8 51401551-801?The total number of removed jumpers, including the parity position, must be odd.
-
Can both boards select the LCN address for K2LCN-8 51401551-801?Use a single approved address-selection location. When the processor selects the address, remove the LCN I/O jumpers or set the CLCN switches to zero as specified for the installed hardware.
-
Which slot is used by K2LCN-8 51401551-801 in a WDA History Module?The documented WDA History Module arrangement places the processor in front slot 1. This is a host-specific installation relationship, not a universal slot rule.
-
What memory boundary should be retained for K2LCN-8 51401551-801?The complete 51401551-801 ordering identity must be retained when matching the K2LCN-8 configuration. Memory capacity, installed firmware and host software requirements must be reconciled against the actual board and node configuration.
-
Does K2LCN-8 51401551-801 include the complete disk interface?No. The History Module uses separate peripheral-controller and drive-interface assemblies. Match those components and the host configuration independently.
