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 HP networking introduces new modules for your HP 5400R zl2, 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 5400R zl2, as of the printing of this manual, are listed on
Features". The latest code can be downloaded from the HP networking Web site at
www.hp.com/networking/support.
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
the module documentation to see what version of switch code is needed. Download
the new code and retest the module.
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 another module, or recover the slot with the cover
plate. Call your authorized reseller or authorized service provider, or use the
electronic support services from HP to get assistance. See the Customer Support/
Warranty card for more information.
