Component Replacement

Before sending a switch for repair or discarding it, format its flash storage to ensure data security and run the reset boot password command to reset its BootROM menu password.

When installed in a normal operating environment, fixed switches do not need dust cleaning. Do not disassemble the equipment.

Some switch models provide the JTAG function through edge connectors on the PCB, as shown in Figure 1. The JTAG function is used for equipment checks and fault diagnosis during maintenance.

If the device is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
