HIMA X-FAN 18 03 (HIMax 18 rack frame dedicated cooling fan module, SIL3 system)

X-FAN 18 03 (often written as X-FAN1803) is a hot-swappable redundant fan module specifically for the HIMax (X series) 18-slot backplane X-BASE-PLATE-18-01, responsible for forced air cooling of the entire machine. It is a standard feature of the SIL3 system, featuring dual fans, hot-swappable, with fault alarm.

III. Key Features (Redundancy + Hot Swap)

1oo1 Redundant Dual Fans

Two fans operate independently, and a single fan failure does not affect the overall heat dissipation of the system

Fan failure automatically alarms (Backplane / CPU diagnosis)

Hot Swap (Online replacement)

No need to stop or power off, simply pull out and replace

Support online identification and status reporting

Intelligent monitoring and alarm

Speed monitoring, stall / stop rotation alarm

Linked with X-CPU-01, faults can be uploaded to the upper computer

Efficient heat dissipation duct

Vertical duct design, CPU/I/O/ power centralized heat dissipation

Compatible with 18-slot full configuration (CPU×2 + I/O×14 + power ×2)

IV. Differences from Other Fan Models (Selection)

X-FAN 18 03: 18-slot dedicated, dual fans, 24VDC, hot swap → Compatible with X-BASE-PLATE-18-01

K9203A: Old H41q/H51q rack fan → Incompatible with X series

X-FAN 10 03: 10-slot backplane (X-BASE-PLATE-10-01) dedicated → Cannot be used for 18-slot

V. Typical Configuration (18-slot System Must Have)

Backplane: X-BASE-PLATE-18-01 ×1

CPU: X-CPU-01 ×2 (Redundant)

Power Supply: PS2000/230 ×2 (Redundant)

Fans: X-FAN 18 03 ×2 (Redundant, slot 17/18)

I/O: X-AI-01 / X-DI-01 etc. ×14

VI. Common Questions

Can it run with a single fan? → Yes, but it is recommended to use dual fans in redundancy to avoid single-point failure.

Does it need separate power supply? → Directly powered by the 24VDC bus on the backplane, no additional wiring required.

Does replacement affect the system? → Hot swap design, online replacement has no impact.
