The DES-3028/28P/28G/52/52P support a console management interface that allows the user to connect to the Switch’s 

management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be 

used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the Switch to use an 

SNMP-based network management software over the network. 

This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation. 

Note: Switch configuration settings are saved to non-volatile RAM using the save command. The current 

configuration will then be retained in the Switch’s NV-RAM, and reloaded when the Switch is rebooted. If 

the Switch is rebooted without using the save command, the last configuration saved to NV-RAM will be 

loaded.

Connecting to the Switch 

The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary 

terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C 

serial cable. Your terminal parameters will need to be set to: 

  VT-100 compatible 

  9600 baud 

  8 data bits 

  No parity 

  One stop bit 

  No flow control 

Users can also access the same functions over a Telnet interface. Once users have set an IP address for your Switch, users can use 

a Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether 

accessed from the console port or from a Telnet interface. 

After the Switch reboots and users have logged in, the console looks like this:
