## Ethernet

On the Settings > Network > Ethernet page, you can configure the library network settings.

The Ethernet configuration is divided in different sections. The general network settings, the settings for each network port (primary and secondary) and a section to reset the internal IP range.

In case a secondary ethernet port is connected and configured, it will be used as backup port when contacting the encryption key server. The primary ethernet port is used as primary port when contacting the key server. Also, Web GUI can be accessed over the configured IP of the secondary port.

General Network Settings

1. Configure or update the Host Name and Domain Name. The Web GUI URL is <Host Name>.<Domain Name>.
2. Use Submit button to apply the changes.

Network Port Settings

It is possible to configure both network ports (Primary and Secondary). It is possible to disable the secondary port completely. Depending on the selected protocol, the section for IPv4 or IPv6 will be available for configuration.

Following settings can be made for each network port:

- Protocol - Either IPv4, IPv6 or IPv4 & IPv6
- Max. Link Speed - 10 MBit, 100 MBit and 1 Gbit (default)
- IPv4 settings

- Method - DHCP or Static
  When DHCP is enabled, the library requests an IP address from a DHCP server each time the library is powered on.
  If method Static is selected, the following additional fields are required:

- IPv4 Address of the library
- Netmask
- Gateway address
- DNS 1 address
- DNS 2 address

- IPv6 settings

- Method - Stateless or Static
  When Stateless addressing is enabled, the device generates an address for itself based on the routing information obtained from a router advertisement and the MAC address. The device can manage up to five global addresses at the same time, which can be assigned from different routers.
  If method Static is selected, the following additional fields are required:

- IPv6 Address of the library
- Prefix Length
- Gateway
- DNS 1 address
- DNS 2 address

1. Configure or update the options listed above. To have the library obtain an internet address from a DHCP server, select the DHCP or Stateless method.
2. Use Submit button to apply the changes.

In addition of the configuration options for each network port (Primary and Secondary), status information is also available:

- MAC Address – A unique identifier for the library controller network interface
- Link Status – Enabled or disabled
- Link Speed – Speed of the Ethernet connection to the library
- Duplex – Enabled or disabled

Reset internal IP Range

For internal communication between modules the tape library uses an Ethernet connection with an internal IP address range. To prevent any conflict between the internal IP address range and the external IP addresses it is required to select the internal IP range before the tape library gets connected to the external Ethernet port.

In case the already configured internal IP range has a conflict with the network environment the library is connected to, the internal IP range needs to be reconfigured.

Whenthis function is started with Submit, the library reset s and the screen to select the internal IP range appears on the Operator Panel. After a new range is selected, the library will finishes the reset and access to the Web GUI is possible again.
