Connecting A Pc To The Oa Serial Port - HP integrity superdome x Service Manual

The service port connection is intended only as a temporary Ethernet connection to the enclosure private
network to eliminate disconnecting the management port from the external management network for
access to the OA during a maintenance event.

Connecting a PC to the OA serial port

If needed for debugging purposes, the OA can be accessed locally through a serial (debug) port
connector on the rear of the OA module. Use a laptop or another computer as a serial console to
communicate with the OA.
IMPORTANT:
Use this interface only for OA debugging purposes or during initial setup for assigning active OA
network information. This connection cannot be maintained under normal server operations.
Procedure
1. Connect a serial cable between the serial port on the computer and the serial port on the OA module.
The following table is for the DB9 serial (RS232) port and shows the pinout and signals for the RS232
connector. The signal direction is DTE (computer) relative to the DCE (OA).
NOTE:
A laptop or PC connected to the OA serial port requires a null-modem cable. The minimum
connection to an external console is pins 2, 3, and 5.
