Key Guidelines for Implementation 39
Setting Up the Modem Port
Use the Administration Console to match your external modem speed.
Then configure the external modem by establishing a connection
between your current Administration Console session and the modem
port.
You must establish a connection to the modem by issuing the
system serialPort connectModem
command after you change the
modem speed and before dialing in. This sequence allows the modem to
synchronize its baud rate with the system.
See the CoreBuilder 3500 Getting Started Guide for terminal port and
modem port pin-outs. For additional information about modem port
settings, see the
Command Reference Guide .
IP Management Interface
An Internet Protocol (IP) management interface allows you to manage the
system in-band through an Ethernet port on a module, or out-of-band
through the out-of-band Ethernet port. You can access the system
through an IP interface in one of the following ways:
■
You can use Telnet to connect up to four concurrent remote sessions
to the Administration Console using a terminal program from a host
computer.
■
You can run Web Management to access its management applications
to manage and monitor your system.
■
You can run an SNMP-based network management application to
manage and monitor your system.
IP is a standard networking protocol that is used for communications
among various networking devices. To gain access to the system using
TCP/IP or to manage the system using SNMP, you must set up an IP
interface for your system. How you set up the IP interface depends on
whether you plan to manage the system in band (with your regular
network traffic) or out of band (with a dedicated network).
For Telnet, Web Management, or SNMP access, you must first define an
IP interface. You can use either an out-of-band or in-band port for the IP
interface, but do not assign the same IP address to both the out-of-band
and in-band ports. Also, be sure not to assign an out-of-band port IP
address that is on the same subnet as any of the in-band IP interfaces.
