Connecting To The Oa With A Local Pc; Connecting A Pc To The Oa Service Port - HP integrity superdome x Service Manual

Connecting to the OA with a local PC

A PC might be connected directly to the OA module in the following two ways:
• Using a terminal emulator through the OA service port (Ethernet). Use this port for normal
communication with the OA. See Connecting a PC to the OA service port.
• Using a standard serial connection through the OA serial port (RS232). This is used for debugging
purposes only and is not used for monitoring or modifying OA settings. See Connecting a PC to the
OA serial port.

Connecting a PC to the OA service port

The OA service port is the compute enclosure link-up connector which also has a laptop icon next to the
up arrow. This port is a 100BaseT Ethernet jack and might be directly connected to a PC RJ45 Ethernet
connector using a standard CAT5 patch cable as the wiring on the link-up connector is crossed over to
allow direct connect to a PC 100BaseT connector.
The Service Port provides direct connection to the active OA module in the compute enclosure. The
network connection is private to the enclosure and cannot be used to access any device outside the
internal enclosure management network. Use the connection to directly access the active OA at the
active service IP address, located on the enclosure Insight Display, Enclosure Info screen.
The laptop or PC connected to the enclosure service port must have DHCP enabled its network
connection. The laptop or PC gets a zero-conf IP address in the range of after a DHCP timeout if the
laptop or PC is running Windows. If the laptop or PC is running Linux, you must probably manually set the
network port to 169.254.2.1 with a netmask of 255.255.0.0.
Procedure
1. Connect a laptop or PC 100/1000Mb Ethernet port to the enclosure service (link-up) port on the OA
interposer using a standard CAT5e patch cable.
2. Access an active OA as follows:
• To access an active OA GUI: Use the active OA service IP address from the Insight Display on
that enclosure as the web address in your laptop or PC browser.
• To access an active OA CLI: Use a Telnet or Secure Shell program based on the configured
network access settings and connect to the active OA service IP address.
3. Log into the OA with the "Administrator" user account and the OA default password located on the OA
toe tag.
For information on using the OA CLI, see the HPE Integrity Superdome X and Superdome 2 Onboard
Administrator Command Line Interface User Guide.
Because none of the configured device bay iLOs have an IP address in the zero-conf IP address range,
you must manually add a network route on the laptop or PC to access the iLO IP address from the
service port. The syntax for using a Windows laptop or PC command shell is as follows:
route add iLO_IP_address mask 255.255.255.255 <OA_service_IP_address>
After the route to an iLO has been added to the laptop or PC, the iLO can be accessed from the OA GUI
or directly using Secure Shell.
The active OA does not support routing from the service port to an interconnect module management
processor. However, if the interconnect module supports the serial connection to the OA, then the OA CLI
CONNECT INTERCONNECT command can be used to connect to an interconnect module.
