5.7.10 Configuring the COM Port
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:
1. Use the arrow keys to highlight the Com field.
2. 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.
!
CAUTION
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.
!
CAUTION
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
Section 5.7.11) to reestablish COM port communications.
