The Management CPU module has two RS-232 ports:
Port #1 connects to a local VT100 terminal. You can view the communication
n
parameters for this port, but you cannot change them via the NMS menus.
Port #2 allows you to run PPP. This port can connect via a modem to the user
n
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.
