Cabletron Systems 2E43-51 사용자 설명서

Upon power up, the COM port is configured to the default settings of 
ENABLED and LM.

To configure the COM port, the user must enable/disable the COM port 
and select an application.

The 2E43-51 COM port supports the following applications:

Local Management connections

American Power Conversion Uninterruptible Power Supply (UPS) 
connections

To configure the COM port, proceed as follows: 

Use the arrow keys to highlight the Com field.

Press the SPACE bar to choose either ENABLED or DISABLED. 
ENABLED supports the connection of a terminal to the COM port for 
a particular application. DISABLED does not support the connection 
of a terminal to the COM port. 

Before altering the COM port settings, read this entire COM 
port configuration section. Altering the COM port settings 
disconnects the Local Management terminal from the port, and 
ends the Local Management session.

Do NOT disable or alter the settings of the COM port while 
operating the current Local Management connection through a 
terminal. Altering the COM port settings disconnects the Local 
Management terminal from the port, and ends the Local 
Management session. If the 2E43-51 was previously assigned 
a valid IP address, reenter Local Management by establishing 
a Telnet connection to the device. If the device does not have a 
valid IP address and the COM port has been disabled or the 
settings changed, reset NVRAM on the 2E43-51 (refer to 

) to reestablish COM port communications.
