Dial-Up Management Console - NEC i-Series Gateway Quick Installation Manual

Dial-Up Management Console

Introduction
The MI includes Zmodem functionality for the DB-9 dial-up management console port. An external
modem attached to the DB-9 port (not included with unit) is required to dial into the i-Series Gateway
management console interface. This console interface allows remote dial-up access using Zmodem
protocol to the management console. (Refer to Appendix A.)
When a dial-up connection is established to the MI of one unit, it is possible to "Rlogin" to other connected
units to access the MI of those units when the network connection between units is not functioning. This
connection allows access to all features and functions of the MI and the ability to configure, monitor, and
troubleshoot the unit from a remote location. (See the figure on page 6.)
