Using the device to log in to an SSH server
You can use the device as an SSH client to log in to an SSH server. If the server is located in a
different subnet than the device, make sure the two devices have routes to reach each other.

Perform the following tasks in user view:

Log in to an IPv6 SSH server.

To work with the SSH server, you might need to configure the SSH client. For information about
configuring the SSH client, see Security Configuration Guide.
Logging in through a pair of modems
You can use a pair of modems to remotely connect to the console port of the device over PSTN when
the IP network connection is broken.
By default, modem dial-in is enabled, and you can dial in to the switch. The default user role is
network-admin. To change modem dial-in parameters, see "Logging in through the console port
locally."
To use a pair of modems to remotely log in to the device:
1. Connect one modem to the serial port of the PC and another modem to the console port of the
device.
2. Connect each modem to the PSTN through a telephone cable.
