The module is 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 it is hot swapped (installed when the switch is
powered on).
Try reinstalling the module. You can do this without having to power down the
switch. When the module is reinstalled, it will be retested automatically. Make
sure to screw in the retaining screws so that the module cannot be inadvertently
pulled out by pulling on the network cables.
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 HP-authorized LAN dealer, or use the electronic support
services from HP to get assistance. See the Customer Support/Warranty booklet
for more information.
Operating code and configuration information is downloaded to each switch
module 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). In this fault condition, an error has occurred in the download
process.

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 12.
