Enabling static address fallback:
NOTE: The Static Address Fallback option executes only when DHCP is enabled.
To enable static address fallback, check the Enable checkbox. To disable, uncheck (clear) the checkbox.
Click Apply.

Enabling the Static Address Fallback option informs the PDU to automatically fall back to a static address if
a DHCP server does not respond after 100-seconds. This is the default state.

Disabling the Static Address Fallback option generates DHCP server requests until the PDU obtains a
dynamic address.
NOTE: If the DHCP server boot time is excessive, you may need to disable the DHCP Static Address Fallback option.
Network defaults
The Switched PDU is configured with the following network defaults to allow unit configuration out-of-the-box
through either Telnet or Web:


Subnet Mask: 255.255.255.0

Gateway: 192.168.1.1
The initial local PC network connection must be configured as noted below:
NOTE: For instructions about reconfiguring the network connection, contact your system administrator. A restart may be required for the
reconfiguration of your network to take effect.

IP address: 192.168.1.x (where x is 2-253)


Setting the IP address, subnet mask, gateway, or DNS address:
In the appropriate field, enter the IP address, subnet mask, gateway address or DNS address and click Apply .
Telnet/SSH
The Telnet/SSH configuration page enables or disables Telnet and SSH support and configures the port number that
the Telnet or SSH server watches.
Enabling or disabling Telnet or SSH support:
Select Enabled or Disabled from the appropriate Server drop-down menu and click Apply .
Changing the Telnet or SSH server port number:
In the appropriate Port field, enter the port number and click Apply .
Enabling or disabling SSH server authentication methods:
The SSH server supports the Password and the Keyboard-Interactive authentication methods for security.
Password is an authentication method in which the SSH client gathers username/password credentials and makes the
authentication request to the SSH sever with the credentials. The Password method is controlled by the SSH client.
Keyboard-Interactive is an authentication method in which the SSH server controls an information field followed by one
or more prompts requesting credential information from the SSH client. The client gathers credential information keyed-in
by the user and sends it back to the server. The Keyboard-Interactive method is controlled by the SSH server.
Individual enabling and disabling of the Password and Keyboard-Interactive authentication methods are supported to
allow an SSH client to be forced to use a specific method. Although both methods are available, by enabling the
Keyboard-Interactive method and disabling the Password method, the SSH client is forced to used Keyboard-Interactive,
which is required to display the login banner.
NOTE: At least one authentication method must be enabled.
Select the Password checkbox and/or the Keyboard - Interactive checkbox and click Apply .
