Troubleshooting
➎The module installed in the slot that corresponds to the letter that is blinking has experienced a self test or initialization fault.
The modules are all tested whenever the switch is powered on, or reset (through the Reset button on the switch, or the Boot or Reset options in the console or web browser interface), and when they are hot swapped (installed when the switch is powered on).
Since the Link and Mode LEDs on the module were lit at least briefly, that indicates that the module did receive power from the switch, but the subsequent download process failed. Either the module is faulty, or it is a new module type that is not yet supported by the operating code on the switch.
As ProCurve Networking introduces new modules for your ProCurve Switch zl, you may have to update the switch with new operating code that supports the new module. The documentation that came with the module will indicate which version of the operating code is needed to support the module. The modules that are supported in your Switch zl, as of the printing of this manual, are listed on
page
First verify the switch has a version of code that supports the module that is indicating the fault. If the module is not one of the ones listed on page
If you have the correct code installed in the switch, try removing and reinstalling the module. You can do this without having to power down the switch. When the module is reinstalled, it will be retested automatically.
If the fault indication reoccurs, the module may have failed. Remove the module from the switch and replace it with a known good module, or install the failed module into an empty slot and retest it. If you remove the module always recover the slot with the cover plate. Call your ProCurve authorized dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty card for more information.
➏In the slot corresponding to the letter that is blinking, a module was installed that is a different type than the previously installed module, and the switch has not yet been reset.
When you “hot swap” modules in the switch slots, if you install a different module type than the one that was previously installed in the slot, you must reset the switch so the switch processor can properly initialize and configure the new module type. The blinking LED informs you that this change of module types has occurred. The module will not work properly until the switch is reset.
You can reset the switch by any of these methods:
•pressing the Reset button.
•power cycling the switch.
•selecting the reset or reboot option from the console, web browser interface, or ProCurve Manager.
