11 Maintaining a Switch
About This Chapter
NOTICE
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 11-1. The JTAG function is used for equipment checks and fault diagnosis
during maintenance.
