Caution:
This article points to cable routing inside the chassis, please be aware of the precautions to prevent damage the comments in chassis.
Purpose:
On FWA-3270 , PSU status can be retrieved through I2C cable which is connected to PSU housing (back plane).
By default, this cable is connected to mother board , so that system can approach PSU status via i2c commands or Advantech utility called "sensor reader"
Sometime, adding LOM (BMC) is an option on FWA-3270. To have BMC can detect PSU status correctly, moving this cable to LOM connector CN4 is required.
Prerequisites:
FWA-3270 supports BMC and Non-BMC SKU, steps in this article only for BMC (LOM) SKU
Target Audience:
Advantech field engineer and RMA members
Procedures/Steps:
1. Find PSU detection Cable from PSU backplane
2.Wire this cable to LOM connector CN4, hear the clip sound to make sure it's well-connected.
3.Power On system and check is PSU sensor readings were shown in sensor data record list.
