BMECXM Module Replacement
Original instructions
About us
Overview
At any time and without turning off the power to the rack, any BMECXM module on the rack can be replaced by another module with compatible firmware.
DANGER
EXPLOSION OR ELECTRIC SHOCK
  • Only perform a hot swap operation in locations known and confirmed to be non-hazardous
  • Use only your hands and suitable insulation equipment.
  • Do not use any metal tools.
Failure to follow these instructions will result in death or serious injury.
WARNING
HAZARD OF ELECTRIC SHOCK
Before attempting to hot swap a BMECXM module:
  • Positively confirm that the rack is connected to the protective earth ground.
  • Positively confirm that you have an equipotential grounding system in place.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
The replacement module obtains its operating parameters over the Ethernet. Assuming that the FDR server is enabled, the transfer occurs to the BMECXM module.
NOTE: You have to understand and plan for the consequences of hot-swapping a module. Disconnecting a module will interrupt communication to the connected CANopen slave devices.
WARNING
UNINTENDED EQUIPMENT OPERATION
  • Thoroughly identify and understand all implications and consequences of operating mode modifications before attempting them with a new device.
  • Take all necessary preventive measures to ensure safe conditions before making operating mode modifications.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Hot Swapping Procedure
To hot-swap the module, follow these steps:
Step
Action
1
Remove the CANopen cable from the module.
2
Remove the module from the backplane.
3
Install the new module to the free slot of backplane.
Tighten the retaining screw to hold the module in place on the rack:
NOTE: The tightening torque is 0.4...1.5 N•m (0.30...1.10 lbf-ft).
4
Reconnect the CANopen cable to the CANopen connector of the BMECXM module.
A bad module connection can lead to an unexpected behavior of the system.
WARNING
UNINTENDED EQUIPMENT OPERATION
  • Tighten the retaining screw of the module.
  • Tighten the retaining screws of the SUB-D 9 CANopen connector.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
Replacing a CANopen Slave
NOTE: For CANopen slave device replacement procedure refer to respective device instructions.
After a CANopen slave device replacement, the BMECXM module sends the initial parameters automatically to the new device that restarts automatically. If you have changed the initial parameters, you need to retransfer them explicitly from the application.
