file:///C|/Users/Nalina_N_S/Documents/NetXtremeII/English/trouble.htm[9/5/2014 3:45:23 PM]

Solution: Enable flow control to reduce the number of packets lost.

Problem: A DCOM error message (event ID 10016) appears in the System Even Log during the installation of the Broadcom
adapter drivers.

Solution: This is a Microsoft issue. For more information, see Microsoft knowledge base KB913119 at

http://support.microsoft.com/kb/913119

.

Problem: Performance is degraded when multiple BCM57710 network adapters are used in a system.

Solution: Ensure that the system has at least 2 GB of main memory when using up to four network adapters and 4 GB of
main memory when using four or more network adapters.

Problem: Remote installation of Windows Server 2008 to an iSCSI target via iSCSI offload fails to complete, and the
computer restarts, repeatedly.

Solution: This is a Microsoft issue. For more information on applying the Microsoft hotfix, see Microsoft knowledge base
article KB952942 at

http://support.microsoft.com/kb/952942.

Problem: Performance drops when a BCM5709C network adapter is connected back-to-back to a switch, MTU = 9000, and
Tx and Rx Flow Control are enabled.

Solution: When enable_cu_rate_limiter is enabled, the device performs flow control in the catchup path to prevent catchup
frames from dropping. The catchup path is used in processing iSCSI out-of-order PDUs. When enable_cu_rate_limiter is
disabled, there is a potential for some drops of iSCSI out-of-order PDUs, which reduces performance. This feature does not
work well when jumbo frame is enabled on any of the client devices. Enable_cu_rate_limiter should be set to disabled when
jumbo frame is enabled.

Problem: The network adapter has shut down and an error message appears indicating that the fan on the network adapter
has failed.

Solution: The network adapter was shut down to prevent permanent damage. Contact Dell Support for assistance.

Problem: When using a BCM57840 4-port adapter in a blade server, ports 3 and 4 show no link.

Solution: The I/O (switch) module must support 32 internal ports. If it does not, ports 3 and 4 cannot establish a link.
