CLI Commands and Messages
Management Overview
Redundant DS3 Network Interfaces
The Wide Bank can have two Controller cards. To provide electronic and/or network redundancy,
each Controller card has a DS3 network interface. The secondary card (B) provides electronics and
route protection against faults that occur on the primary Controller card (A) and its interface.
Figure 8-1 Management Port Connections
Telnet Interface
You can use Telnet to remotely access the Wide Bank after setting up the IP address of the Ethernet
port (see IP on page 8-48). The Telnet interface is identical to the VT100 interface except that it
uses the TCP/IP protocol for data transport and is accessed through the 10Base-T Ethernet
connection.
You can open a Telnet session using the IP address. After pressing the Enter key to initiate the
connection, you can then log in as usual. When finished, log out using the exit command before
disconnecting the Telnet session.
If you do not exit the session, it will continue for 16 minutes, and any attempt to login through
Telnet or the RS-232 port will fail. If this occurs, type Ctrl k on the terminal connected to the Wide
Bank RS-232 port to end the one-sided Telnet session. If the Telnet session is idle for five minutes,
you will be automatically logged out.
