Chapter 1 Switch Management
1.1 Management Options
After purchasing the switch, the user needs to configure the switch for network management.
SS3GR50I/26I series Switch provides two management options: in-band management and
out-of-band management.
1.1.1 Out-Of-Band Management
Out-of-band management is the management through Console interface. Generally, the user will
use out-of-band management for the initial switch configuration, or when in-band management is
not available. For instance, the user must assign an IP address to the switch via the Console
interface to be able to access the switch through Telnet.
The procedures for managing the switch via Console interface are listed below:
Step 1: Setup the environment:
Fig 1-1 Out-of-band Management Configuration Environment
As shown in Fig 1-1, the serial port (RS-232) is connected to the switch with the serial cable
provided. The table below lists all the devices used in the connection.
