5.7.10 Configuring the COM Port

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

Before altering the COM port settings, ensure that the

!2H23-50R or 2H33-37R is set with a valid IP address. (Refer to

CAUTION	Section 5.7.1, Setting the IP Address.) Read this entire COM
	port configuration section before changing the settings of the
	COM port.

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:

1.Use the arrow keys to highlight the Com field.

!

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 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 Appendix C) to reestablish COM port communications.

2.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.

3.Use the arrow keys to highlight SAVE. Press ENTER.
