connectivity of servers to the external networks.
For more information, see “Supported configurations (on page 14)" and “Recommended stacking
connections (on page 21)."
NOTE: Virtual Connect does not support stacking for FC modules, so each VC-FC module
requires uplink connections to the external FC SAN environment.
To initiate this wizard, click the Network Setup Wizard link on the homepage, or select Network Setup
Wizard from the Tools pull-down menu. You must have network privileges to access the Network Setup
Wizard.
MAC Address Settings
At this point in the wizard, you are asked to select the type of Ethernet MAC addresses to be used on the
server blades within the enclosure. Choose either the server factory default Ethernet MAC address that came
with the server or the Ethernet MAC addresses assigned by Virtual Connect. Be sure to fully understand the
following information before making this selection.
IMPORTANT: Configuring Virtual Connect to assign server blade MAC addresses requires
careful planning to ensure that the configured range of MAC addresses is used once within the
environment. Duplicate MAC addresses on an Ethernet network can result in a server network
outage.
Each server blade Ethernet NIC ships with a factory default MAC address. The MAC address is a 48-bit
number that uniquely identifies the Ethernet interface to other devices on the network. While the hardware
ships with default MAC addresses, Virtual Connect can assign MAC addresses that override the factory
default MAC addresses while the server remains in that Virtual Connect enclosure.
