5.7.10 Conﬁguring the COM Port

Upon power up, the COM port is conﬁgured to the default settings of

ENABLED and LM.

The 2M46-04R 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 1 field.

2. Press the SPACE bar to choose either ENABLED or DISABLED.

ENABLED allows the COM port to be connected to the terminal and

used for a particular application. DISABLED disables the COM port

connection to the terminal.

CAUTION

Before altering the COM port settings, ensure that a valid IP

address is set. Refer to Section 5.7.1. Read this entire COM

port conﬁguration section before altering the COM port

settings.

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 2M46-04R 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

2M46-04R (refer to Appendix C) to reestablish COM port

communications.

CAUTION

If the COM port is conﬁgured without a valid IP address, the

screen shown in Figure 5-11 displays.

Do not continue unless the outcome of the action is fully

understood. If the Warning screen displays, continue on to

step 3, otherwise, proceed to step 4.
