Using Telnet or SSH session Connect to the Fabric OS through a Telnet or SSH connection or through a console session on the serial port. The switch must also be physically connected to the network. If the switch network interface is not configured or the switch has been disconnected from the network, use a console session on the serial port as described in the next section. NOTE: To automatically configure the network interface on a DHCP-enabled switch, plug the switch into the network and power it on. The DHCP client automatically gets the IP and gateway addresses from the DHCP server. The DHCP server must be on the same subnet as the switch. See "Activating DHCP" on page 29 for more details. Rules for Telnet connections: • Never change the IP address of the switch while two Telnet sessions are active; if you do, your next attempt to log in fails. To recover, gain access to the switch by one of these methods: • You can use Web Tools to perform a fast boot. When the switch comes up, the Telnet quota is cleared. (For instructions on performing a fast boot with Web Tools, see the Web Tools Administrator's Guide.) • If you have the required privileges, you can connect through the serial port, log in as root, and use operating system commands to identify and kill the Telnet processes without disrupting the fabric. • For admin level accounts, Fabric OS limits the number of simultaneous Telnet sessions per switch to two. For more details on session limits, see "Configuring the Telnet protocol" on page 92 and "Managing user accounts" on page 55. To connect using Telnet: 1. Verify that the switch's network interface is configured and that it is connected to the IP network through the RJ-45 Ethernet port. Switches in the fabric that are not connected through the Ethernet can be managed through switches that are using IP over Fibre Channel. The embedded port must have an assigned IP address. 2. Open a Telnet connection using the IP address of the logical switch to which you want to connect. Enter the account ID at the login prompt. See "Changing passwords" on page 25 for instructions on how to log in for the first time. 3. Enter the account ID at the login prompt. 4. Enter the password. If you have not changed the system passwords from the default, you are prompted to change them. Enter the new system passwords, or press Ctrl-C to skip the password prompts. See "Changing default account passwords at login" on page 26. 24 Standard features
