# Using telnet

Follow the procedure below to use telnet.

- Only one user at a time can log in to perform remote maintenance.

- If you are using Windows Vista/7, you must enable the telnet server and telnet client beforehand.

1. Use the IP address or the host name of the machine to start telnet.

   `% telnet "IP address"`

   For example, if the machine's IP address is "192.168.15.16", enter the address as follows:

   `% telnet 192.168.15.16`

2. Enter your user name and password.

   For details about the user name and password, consult your network administrator.

3. Enter a command.

4. Quit telnet.

   `msh> logout`

   A message asking you to confirm saving the changes appears.

5. Enter "yes" to save the changes, and then press the [Enter] key.

   If you do not want to save the changes, enter "no", and then press the [Enter] key. To make further changes, enter "return" at the command line, and then press the [Enter] key.

- If the message "Can not write NVRAM information" appears, the changes are not saved. Repeat the procedure above.

- When the changes are saved, the network interface board is reset automatically with that changes.

- When the network interface board resets, the print job in print process will be printed. However, print jobs in queue will be canceled.
