5.15.11 Configuring the COM Port
The 6E12X-26 and 6E13X-25 COM ports support 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.
The COM port must be ENABLED if it will be used for Local
Management or UPS applications. Select DISABLED to disable the
COM port for additional module security.
!
CAUTION
Before altering the COM port settings, ensure that a valid IP
address is set for the module or chassis. (Refer to
Section 5.15.1 , Setting the IP Address .) Read this entire
COM port configuration section before changing the settings of
the COM port.
!
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 module was previously assigned a
valid IP address, reenter Local Management by establishing a
Telnet connection to the module. If the module does not have a
valid IP address and the COM port has been disabled or the
settings changed, reset NVRAM on the module (refer to
Section C.2 ) to reestablish COM port communications.
!
CAUTION
If the COM port is reconfigured without a valid IP address set
on the module or chassis, the message shown in
Figure 5-20
displays. Do not continue unless the outcome of the action is
fully understood.
