down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation comply with recommendations. (See “Making Network Connections” in Chapter 3.)
Management Interface
Terminal Emulation
If the terminal attached to the console port is not operating properly, check that:
1.the attached terminal or terminal emulator is set to VT100
2.you are using the correct cable type (See Chapter 4, “Configuration and Management”) and that it is properly connected.
3.the console is configured properly (8 data bits, 1 stop bit, no parity and 9600 or 19200 bps).
4.if you are using terminal emulation, there are no IRQ conflicts.(i.e., Make sure device drivers are not using the same IRQ required to run the COM port).
Telnet
If you have trouble establishing a link to the System
Configuration Program using Telnet:
1.Check to make sure the network connection is valid.
2.Verify that the correct IP address for the switch has been entered at the Telnet location.
3.Make sure the port on the switch through which you are trying to establish a Telnet connection is enabled. (See Chapter 4, “Configuration and Management”)
4.Check the cabling between the Telnet site and the switch.
