XSCF Connection via a Serial Port
Establish an XSCF connection via a serial port. Connect the serial port as shown in
FIGURE 3-1
. An XSCF connection via the serial port has the following functions and
advantages:
■
XSCF Shell
■
Advantageous when connection to the LAN is not desirable for reasons of
security
■
Displaying the initial diagnostic message at the XSCF connection
XSCF Connection via XSCF-LAN and Serial Ports
Establish the XSCF connection via XSCF-LAN and serial ports. This type of
connection is also shown in
FIGURE 3-1
. The XSCF connection via both ports has the
following advantage in addition to those for the connection via the XSCF-LAN port.
■
A user who connected with the serial port can safely use the XSCF Shell.
3.2.2 XSCF-LAN and Serial Connection Purposes
The XSCF Unit has one serial port and two XSCF-LAN ports with 10/100 Mbps
interfaces. This section describes examples of using the XSCF-LAN ports and the
serial port.
Caution – IMPORTANT - The IP address of XSCF-LAN#0 and IP address of
XSCF-LAN#1 must be specified in different subnet addresses.
Using Two LAN Ports and Making the LAN Redundant
FIGURE 3-6
shows an example of a configuration where the two XSCF-LAN ports of
one XSCF Unit are used for the same purpose. This configuration makes the
XSCF-LAN redundant. The purpose is as follows:
■
The two LANs, which are redundantly configured, are used for the system
administrator
■
The two LANs, which are redundantly configured, are used for the remote
maintenance service.
■
FE uses either of the two LANs or a maintenance terminal that is serially and
directly connected.
