ProCurve Switch vl Modules
Troubleshooting
G
The module 
installed in the slot 
that corresponds to 
the letter that is 
flashing 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 Reboot or Reset options in the console or web 
browser interface), and when they are hot swapped (installed when the switch is 
powered on).
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 another module, or install a slot cover plate. Call your 
ProCurve authorized LAN dealer, or use the electronic support services from 
ProCurve to get assistance. See the Customer Support/Warranty card for more 
information.
H
The module-based 
network port for 
which the Link LED 
is flashing has 
experienced a self 
test or initialization 
failure.
During the module self test, described in tip letter G earlier in this table, each network 
port is also tested. If the port self test fails, the individual port is not usable, but the 
rest of the ports on the module, which have passed their self test, will continue to 
operate normally.
To verify the port has failed, try removing and reinstalling the module. If the port is 
a mini-GBIC, you can remove and reinstall the mini-GBIC without having to remove 
the module. The mini-GBICs are tested when they are hot swapped. If the port fault 
indication reoccurs, and you need to be able to use the port, you will have to replace 
the mini-GBIC or the module. In the meantime, all the other module ports will operate 
normally. 
I
The module 
installed in the slot 
that corresponds to 
the letter that is 
flashing is an 
invalid or 
unsupported 
module.
Ensure you have installed a vl module in the slot. ProCurve gl and xl modules will fit 
in the slot, but they are not compatible with your ProCurve vl switch. Check to ensure 
the module has a “vl module” label on it.
If the module does not have a “vl module” label, remove the module from the switch 
and replace it with a vl module, or re-cover the slot with the cover plate. You can 
remove and replace the module without having to power down the switch. Call your 
ProCurve authorized LAN dealer, or use the electronic support services from 
ProCurve to get information on supported Switch vl modules. The vl modules that 
are available as of the printing of this manual are listed on page 1.
If the module has a “vl module” label, then the LED pattern indicates that the module 
is unsupported in the version of software currently running on the switch. As 
ProCurve introduces new modules for the vl switches 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 latest code can be downloaded from the 
ProCurve Web site at www.procurve.com. Download the new code and retest the 
module by booting the switch with the new software.
