Server Blade Connection
For a server blade, you can connect directly through the SUV cable to the serial console or you
can connect using the MP LAN internal connection in the blade enclosure.
NOTE: You do not cable up a separate MP LAN cable to each server blade.
In most circumstances, it is not necessary to physically connect to the iLO 2 on a Server Blade. The
iLO 2 on server blades typically use the MP LAN connection in the blade enclosure, and typically
get their LAN IP addresses assigned using the OA. In the rare cases where a physical connection
directly to a server blade iLO 2 is necessary, use one of the following methods:
Connect to iLO 2 with DHCP enabled. Use the OA/iLO network port on the rear of the
enclosure. If the OA/iLO network port on the enclosure is connected to the local network that
has a DHCP server, your iLO 2 MP IP address is automatically generated by the DHCP server.
The server blade is factory set with DHCP enabled.
Connect to iLO 2 with no network connection. Use the console serial port on the SUV cable.
If the enclosure is not connected to any network, you must configure your server through the
console serial port (RS-232) on the SUV cable.
NOTE: The local video port can be used to access the console at EFI or potentially the OS, but
is not a connection to iLO 2. The USB provides keyboard and mouse to the operating system on
HP Integrity server blades. Also, server blades do not support directly connecting a modem to the
MP (called the remote RS-232 port on servers), so there is no remote RS-232 connection on the
server blade. In addition, there is no LAN connection on the front of the server blade.
Connecting to a Server Blade iLO 2 Using the Console Serial Port
If the enclosure is not connected to any network, you must configure your server through the console
serial port (RS-232) on the SUV cable. Use this procedure to configure the console serial port to
enable iLO 2 access. To perform this procedure, you need a terminal emulator (for example, a
laptop using hyperterm) to connect to the server blade.
NOTE: On the HP Integrity server blades, you have access to two serial ports through the RS-232
connector. The default setting is for the iLO 2 interface, the other is for an AUX UART directly
connected to the host operating system and can be used for any serial device (terminal, debug
port, and so on). HP recommends using the AUX UART for server blade setup and debug purposes
only.
You can use a command to toggle between the two ports. However, if access to the iLO 2 MP TUI
CLI is not possible through Telnet and if the port mode of operation is set to the AUX UART, perform
a hard reset of iLO 2 to set it to the default shipping settings. To perform a hard reset, push the
recessed MP Reset button.
TIP: It is not necessary to physically connect to iLO 2 through the console serial port to perform
management tasks. Use the OA/iLO 2 LAN port to communicate with any iLO 2 in the enclosure
and the OA. You can use the LCD panel and the OA to configure and determine the iLO 2 MP
LAN address.
