APPARATUS FOR CONNECTING DEBUG PORT OF REMOTE SYSTEM, AND METHOD FOR OPERATING THE SAME, CAPABLE OF MONITORING STATES OF EACH BOARD OF A SYSTEM BY CONNECTING MONITOR PORT OR DEBUG PORT THROUGH TELNET IN REMOTE PLACE

摘要

PURPOSE: An apparatus for connecting a debug port of a remote system, and a method for operating the same are provided to take a temporary measure for a failure by remotely confirming the state of each board of a system. CONSTITUTION: A CPU(Central Processing Unit)(100) drives a multi user telnet server, takes charge of routing between an RS-232 line and a LAN(Local Area Network)(320), or connects the RS-232 line with a modem(420), and multiplexes the RS-232 line. An Ethernet block(300) is formed of an MII(Media Independent Interface)(310) and a physical layer for forming an Ethernet port for telnet connection. A modem matching unit(400) controls the modem connection. A multi port SCC(Serial Communication Controller)(500) controls serial communication to execute RS-232 communication with each board. An RS-232 block(600) provides a plurality of RS-232 lines to execute RS-232 communication with each board.
