Tip
Number Problem
➊
The module installed in
the slot that
corresponds to the
letter that is flashing is
an invalid module.
➋
The module installed in
the slot that
corresponds to the
letter that is flashing
has experienced a self
test or initialization
fault.
➌
A module was installed
in the slot that is a
different type than the
previously installed
module, and the switch
has not yet been reset.
The fact that the Link and Mode LEDs never are lit on the module indicates that
it is a Procurve Switch GL module and should not be used in your XL switch.
Make sure that you have installed an XL module in the slot. HP
Procurve GL modules will fit in the slot, but they are not compatible
with your Procurve XL switch. Check to make sure that the module
has a magenta "xl module" symbol on it.
Remove the module from the switch and replace it with an XL module, or recover
the slot with the cover plate. You can remove and replace the module without
having to power down the switch. Call your HP-authorized LAN dealer, or use
the electronic support services from HP to get information on supported Switch
XL modules.
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).
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 software on the switch.
As Hewlett-Packard introduces new modules for your HP Procurve Switch XL,
you may have to update the switch with new software that supports the module.
See the module descriptions at the beginning of this guide to find out which
version of the switch software is needed to support the module.
First, verify that the switch has a version of software that supports the module
that is indicating the fault. If necessary, download the new software and retest
the module. The latest software can be downloaded from the HP Procurve web
site at http://www.hp.com/go/hpprocurve, or software that supports the module
is on a CD-ROM that is included with your module.
If you have correct software 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 is faulty. Remove the module from the
switch and replace it with another module, or recover the slot with the cover
plate. Call your HP-authorized LAN dealer, or use the electronic support services
from HP to get assistance. See the Customer Support/Warranty card for more
information.
When you "hot swap" modules in the switch slot, 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 flashing LED informs you that this change of module types has
occurred. The module will not work properly until the switch is reset, as indicated
by all the module's LEDs staying on until the switch is reset.
See "Resetting the Switch" on page 15.
