HP 3PAR T-Class Installation and Deinstallation Guide

C Connecting the Maintenance PC
Many storage system installation and upgrade procedures require a direct serial connection to a
controller node from a maintenance PC. Installation and upgrade procedures also require a
connection from the maintenance PC to the storage system service processor.
This appendix describes how to obtain a direct serial connection to a controller node from a
maintenance PC running a version of Windows Operating System (2000 or above). It also describes
all recommended methods of communicating with the service processor through the maintenance
PC.
The method you select depends on the resources available to you. 3PAR does not provide the
third-party software described in this appendix, nor does it support connection methods not described
in this appendix.
NOTE: PUTTy, SecureCRT®, and HyperTerminal are third party software and HP makes no
representations or warranties with respect to such software.
NOTE: In this and other chapters, the command-line examples use bold type to indicate user
input and <angle brackets> to denote variables. Examples may not match the exact output
of your system.
Connecting to a Controller Node
The maintenance PC connects directly to a controller node through a serial cable using a terminal
emulation software compatible with a Windows operating systems (e.g. HyperTerminal, PuTTY,
SecureCRT or Reflection X).
The following example of instructions uses HyperTerminal to connect to the controller node.
Use the following table to configure the connection settings of a compatible terminal emulation
software.
