Reasons for Resetting the Switch
Generally, you only need to reset the switch when it needs to recognize a
change in its hardware or software (console) configuration. Some
circumstances in which you will need to reset the switch are:
■ Installing a module in a slot that was previously occupied by a different
type of module, the switch must be reset after the new module is installed
so the switch processor can properly initialize and configure the new
module type.
Note When a module is exchanged for a different type, until the switch is reset
the module will not operate, the Module Status LED (orange) for the slot
will blink, thechassisfaultLED will blink simultaneously, andalltheLEDs
on the module will stay on continuously.
■ Changing certain switch configuration parameters through the console
interface. (In this case, the console provides indications when the switch
must be reset for the configuration change to be activated.)
You do not need to reset the switch when:
■ Installing a module in a previously unused slot.
■ Replacing a module with the same type of module.
Methods of Resetting the Switch
You can reset the switch by any of these methods:
■ pressing the Reset button. On the 8212 zl or 8206 zl switch, this is the
System Reset button on the System Support module.
■ power cycling the switch (if both power supplies are being used, you will
have to disconnect both power cords)
■ issuing the boot command from the switch console CLI, or selecting the
Reset or Boot option from the switch console menu, Web browser inter-
face, or ProCurve Manager
