3com 9000 SX User Manual

The command-line interface built into the Switch is accessible by way 
of the 9-pin, RS-232 console port located on the rear of the unit. 

Once the connection is established, you will see the system prompt and 
you may log on.

Any Telnet facility should be able to communicate with the Switch over 
a TCP/IP network. Up to three active Telnet sessions can access the 
Switch concurrently. The Telnet connection will time out after three 
minutes of inactivity. If a connection to a Telnet session is lost 
inadvertently, the Switch will terminate the session within three 
minutes.

Before you can start a Telnet session you must set up the IP parameters 
described in “Configuring Switch IP Parameters” on page 3-5. Telnet is 
enabled by default.

To open the Telnet session, you must specify the IP address of the 
device that you want to manage. Check the user manual supplied with 
the Telnet client you are using, if you are unsure of how to do this.

Once the connection is established, you will see the system prompt and 
you may log on.

In order to manage the Switch by way of a Telnet connection or by 
using an SNMP Network Manager, you must configure the Switch IP 
parameters. Switch IP parameters are configured on a per-VLAN basis.

If you are using IP and you have a BOOTP server set up correctly on 
your network, you will need to add the Switch Media Access Control 
(MAC) address, the IP address, subnetwork mask, and default gateway 
to the BOOTP server. The Switch MAC address is shown on the rear 
label of the Switch. 

Once this is done, the IP address, subnetwork mask, and default 
gateway for the Switch will be downloaded automatically. You can then 
start managing the Switch without further configuration.
