Alarm Conditions that Cause Clock Source Failure
Table 31 lists the alarms conditions that cause different cards to fail as clock
sources.
Viewing and
Configuring RS-232
Parameters
The Management CPU module has two RS-232 ports:
n
Port #1 connects to a local VT100 terminal. You can view the communication
parameters for this port, but you cannot change them via the NMS menus.
n
Port #2 allows you to run PPP. This port can connect via a modem to the user
management network. You can view and configure communications
parameters for this port via the NMS menus.
You must configure your terminal or workstation to match the default settings of
RS-232 port #1 and normally you will want to do the same for port #2.
Table 32 lists the default settings for the RS-232 ports.
To use other settings for port #2, follow these steps:
1 From the System Administration menu, select [6] RS-232 Port 2 Configuration to
display the RS-232 Port #2 Configuration menu, shown in Figure 77.
Selecting [5] RS-232 Port 1 Configuration displays the current settings only—The
RS-232 Port 1 Configuration menu does not provide options for changing the
communication parameters for port #1.
