NOTE
Observe the LEDs on adapter ports (stand-up adapters only). Illuminated LEDs indicate
connection, link activity, and connection speed negotiated with the attached device. For
the meaning of LED operation, refer to the Brocade Adapters Installation and Reference
Manual.
• If the system freezes perform the following tasks:
a. Verify whether the host system firmware supports PCIe specifications listed in the Brocade
Adapters Installation and Reference Manual. If not, download a firmware update to
support the adapter.
b. Verify compatibility by reviewing the Brocade interoperability matrixes on the Brocade
adapters website at www.brocade.com/adapters .
c. On Windows systems, determine when the system freezes during the boot process. If it
freezes as the driver loads, uninstall and reinstall the driver. If it freezes during hardware
recognition, uninstall both the driver and adapter, then reinstall both.
d. Remove the adapter and reboot the system. If the system boots, reinstall the adapter.
e. Reseat the adapter in the host system.
f. Uninstall and reinstall the driver.
g. Try installing the adapter into a different compatible slot.
h. Try installing the adapter into another host system. If the problem does not occur, the
adapter may not be compatible with the original host system. If the problem occurs in the
new system, replace the adapter.
