In addition to the 10GbE connectivity needs, the iLO connection on each DL also needs to be connected
and configured on the same management network as the 10GbE Ports on the DLs. There are several
ways to do this, for example connecting the 1GbE connections to an existing 1GbE switch that is on the
same Layer 2 management network (VLAN) as the 10GbE components. You could also insert a
1000BASE-T RJ45 SFP (GLC-T) in to the Cisco Nexus 5672UP switch and use ports on the switches for
the iLOs as well.

Configuring the switches
The following procedures describe an example of how to configure the two Cisco Nexus 5672UP switches
for use in an HC380 for the general virtualization configuration. Although two 10GbE based switches are
used here in this example, the same steps can be leveraged for a 1GbE based HC380 solution using any
Cisco Nexus OS 7 1GbE based device, taking into account the additional 1GbE connections that are
required. For more information about the connectivity requirements, see "Configuring the network
switches (on page
)."
The example below assumes you already have a 1GbE infrastructure where your iLO from each HC380
node are connected. This 1GbE infrastructure must be able to communicate to the Cisco Nexus 5672UP
switches we are setting up below. Hewlett Packard Enterprise requires that all connections from the
HC380 (iLO, 10GbE, and/or 1GbE) be connected to the same layer 2 and layer 3 networks.
Connecting to the serial console port
For each switch in the configuration, initial setup will be done over the serial port. This section will show
you how to connect to the serial port.
1.
This task will require a Cisco RJ45 to DB9 console cable to connect the serial port as well as a serial
terminal or serial terminal emulator (Laptop for example) with an available serial port (DB9)
connector.
2.
Connect a serial terminal or laptop/server running a terminal emulator to the serial port of the Cisco
Nexus 5672UP switch. The serial port is located on the front (power side) of the switch.
3.
On the laptop/server, open up a terminal emulation program (i.e. Tera Term) and select the serial
connection option with the serial port configuration
