Cabletron Systems 2H33-37R 사용자 설명서

Chapter 5: Local Management

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

The COM port supports the following applications:

Local Management connections

American Power Conversion (APC) 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. 
The COM port must be enabled to use it for Local Management or 
UPS applications. Select DISABLED to disable the COM port for 
additional device security.

Use the arrow keys to highlight SAVE. Press ENTER.

Before altering the COM port settings, ensure that the 
2H23-50R or 2H33-37R is set with a valid IP address. (Refer to 

port configuration section before changing the settings of the 
COM port.

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 2H23-50R or 2H33-37R 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 
using mode switch 7 on the 2H23-50R or 2H33-37R (refer to 

) to reestablish COM port communications.
