HP Integrated Lights-Out 2 - Manual (Page 62)

iLO 2 provides support for servers that might not have an iLO 2 Dedicated Management NIC. On
servers using the iLO 2 Dedicated Management NIC, the standard hardware configuration provides
iLO 2 network connectivity only through the iLO 2 Shared Network Port connection. iLO 2 detects
the lack of an iLO 2 Dedicated Management NIC and automatically defaults to the Shared Network
Port. On some of these servers, an iLO 2 Dedicated Management NIC might be available as a
hardware option. If an iLO 2 Dedicated Management NIC is available as a hardware option, iLO
2 defaults to the installed iLO 2 Dedicated Management NIC. On servers using the iLO 2 Dedicated
Management NIC, you can enable shared network port operation through the iLO 2 interface.
The iLO 2 Shared Network Port uses the network port labeled NIC 1 on the rear panel of the
server. NIC numbering in the operating system can be different from system numbering. The iLO
2 Shared Network Port does not incur an iLO 2 performance penalty. Peak iLO 2 traffic is less
than 2 MB (on a NIC capable of 1000-Mb speeds), and average iLO 2 traffic is infrequent and
low.
The Shared Network Port is not available on HP ProLiant ML310 G3, ML310 G4, BL20p G4, and
all c-Class blade servers.
iLO 2 Shared Management Port features and restrictions
iLO 2 Shared Network Port and the iLO 2 Dedicated Management NIC port are used for iLO 2
server management. You can only use the iLO 2 Shared Network Port and the iLO 2 Dedicated
Management NIC port for iLO 2 server management. The iLO 2 Shared Network Port and the iLO
2 Dedicated Management NIC port cannot operate simultaneously. If you enable the dedicated
iLO 2 NIC, you will disable the iLO 2 Shared Network Port. If you enable the iLO 2 Shared Network
Port, you will disable the dedicated iLO 2 Dedicated Management NIC.
However, disabling the Shared Network Port does not completely disable the system NIC. Regular
network traffic still passes through the system NIC. When Shared Network Port network traffic is
disabled, any traffic going to or originating from iLO 2 will not pass on to iLO 2 through the Shared
Network Port because the Shared Network Port is no longer shared with iLO 2.
The Shared Network Port must not be considered an availability feature. The Shared Network Port
is intended to allow managed network port consolidation. The use of this feature can create a
single failure point, that is, if the port fails or is unplugged, both the host and iLO 2 become
unavailable to the network.
Enabling the iLO 2 Shared Network Port feature
The iLO 2 Shared Network Port feature is disabled by default. This feature can be enabled through
one of the following:
•
The iLO 2 RBSU
•
The iLO 2 web interface
•
XML scripting
Enabling the iLO 2 Shared Network Port feature through iLO 2 RBSU
1. Connect the server's NIC port 1 to a LAN.
2. When prompted during POST, press the F8 key to enter iLO 2 RBSU.
3. Select Network>NIC>TCP/IP, and press the Enter key.
4. In the Network Configuration menu, toggle the Network Interface Adapter Field to Shared
Network Port by pressing the space bar. The Shared Network Port option is only available
on supported servers.
