Hardware Diagnostic TestsReasons 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.
N o t e | 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, the chassis fault LED will blink simultaneously, and all the LEDs |
| 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 8212zl, this is the System Reset button on the System Support Module. On the 5400zl Series, this is the Reset button on the Management 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
