If the system does not freeze when rebooted and operates correctly, use the following
information to resolve the problem:
a. Check for faulty cable and cable connections.
b. Try rebooting the system without any connectivity to the switch. This will help isolate any
hang caused by switch and device interactions.
c. Reseat SFPs in the adapter (stand-up adapters only). Determine whether the installed
SFPs are faulty by observing LED operation by the adapter ports. If all LEDs are flashing
amber, the SFP is invalid and may not be a required Brocade model. You can also verify
SFP operation by replacing them with SFPs in a known operating condition. If the problem
is resolved after replacement, the original SFP is faulty.
d. Check for conflicts with attached devices. Verify that data speed (1 to 8 Gbps) and
connection topology (for example, point-to-point) for devices attached through the adapter
are compatible with settings on the adapter port. Although auto may be set, configuring
settings manually on the adapter port and devices may allow connection. Also, note that
the adapter only supports point-to-point connection topology. Refer to the Brocade
Adapters Administrator's Guide for procedures to configure adapter ports.
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 compatibility matrices on the Brocade
website at www.brocade.com.

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 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.
