HIMA HIMax X-SB 01 System Bus Module

Maximum relative humidity of 95% (without condensation)

Installation and configuration process

（1） Module installation and removal

Installation prerequisites

It is necessary to cooperate with the dedicated connector board on the motherboard (slot 1 on the left board and slot 2 on the right board), and label the number of supported slots (10/15/18 slots) and slot IDs on the connector board;

It is necessary to install matching fan components to ensure forced heat dissipation (refer to the HIMax system manual). The time to open the fan bracket cover during operation should be less than 10 minutes to avoid heat dissipation failure.

Operation steps

Installation: Open the fan bracket cover → Insert the top of the module into the hook guide → Rotate the module downwards until it locks into place → Tighten the fixing screws → Close the cover and lock it;

Disassembly: Open the cover plate → Loosen the screws → Rotate the module upwards to detach from the guide rail → Remove the module → Close the cover plate.

（2） SILworX configuration configuration

Core Parameters (Module tab)

Network parameters: configure IP address, subnet mask, default gateway, rate mode (recommended automatic negotiation), flow control mode (recommended automatic negotiation);

Safety related parameters:

MAC Learning: Default "Conservative" (ARP cache locking for at least one aging cycle to prevent ARP spoofing), "Tolerance" mode is suitable for scenarios that require fast updates of MAC addresses;

ICMP mode: default "Echo Response" (supports ping testing, balancing security and diagnosis), "No ICMP Responses" has the highest security but cannot ping detect.

Routing Configuration (Routing tab)

Supports up to 8 routing entries, requiring configuration of destination IP address, subnet mask, and gateway for cross network communication (such as connecting to other baseboards or external devices).

Operation, Maintenance, and Lifecycle Management

（1） Daily operation and diagnosis

operation monitoring

The module does not require direct operation and can be remotely controlled through the PADT tool. The running status can be viewed in real-time through the LED (such as the Run green light indicating normal), and detailed fault information (such as IP address conflicts and bus interruptions) can be read on the SILworX diagnostic interface.

Fault handling

Common faults: IP address conflict (PADT and H/F/Col lights flashing slowly at the same time) → Reconfigure IP; Bus transient interference (Up/Down lights flashing slowly) → Check cable connection or replace CAT 5e cable;

Initialization phase fault: If the fault still reports after initialization (such as the Error light being constantly on), it is necessary to check the module power supply, configuration parameters, or replace the module.

（2） Maintenance and scrapping

regular maintenance

Operating system update: Load the latest version of the operating system during system downtime (modules need to be in STOP state, refer to SILworX online help);

Proof Test: It needs to be performed every 10 years to ensure that the module's safety functions are functioning properly (see HIMax Safety Manual HI 801 003 E for detailed procedures).

Transportation, storage, and scrapping

Transportation/Storage: Original factory packaging (anti-static and flame-retardant) is required to avoid mechanical impact and static electricity;

Scrap: Industrial users need to dispose of modules containing electronic components in accordance with environmental protection requirements. They can contact HIMA to sign a scrap agreement, which prohibits the arbitrary disposal of modules containing electronic components.
