E.4 IR-IP Management Subsystem, General

Introduction The IR-IP interface module management subsystem supports the following
functions:
• Preliminary configuration
• Configuration of management access parameters
• Advanced configuration of IR-IP parameters
• Collection and display of statistical performance data
• Maintenance functions, which include:
Software downloading
Resetting of various subsystems
Display of error log
Ping utility, for checking IP connectivity.
The management subsystem of the IR-IP interface module is a separate,
independent entity, and therefore it cannot be managed through the
HCD-E1 management subsystem.
The communication with the IR-IP management subsystem is made through
the local LAN interface connector of the IR-IP module, designated
10BASE-T, using the Telnet protocol. Passwords can be used to prevent
unauthorized access.

Accessing the

IR-IP

Management

Subsystem

The IR-IP interface module must be configured in accordance with the
specific requirements of the user’s application before it can be used in the
user’s network. As a result, it is not possible to supply default parameters to
enable IR-IP to start service without any preliminary configuration.
Therefore, to enable the user to establish Telnet communication and
configure IR-IP, IR-IP is delivered with a factory-default set of parameters.
The factory-default parameters are automatically used:
• Before the IP router is configured by the user, e.g., when a new HCD-E1
with IR-IP interface module is put into operation
• After the user’s configuration parameters have been erased.
