Redundant NIC
A Redundant NIC ensures that the CN9000/CN9600/CN9900/CN9950 is
always online by switching to another network adapter in case the primary
connection fails.
Check Redundant NIC if you are using the secondary LAN port for a
second IP address.
If you are using the secondary LAN port for a second IP address, leave
Redundant NIC unchecked. Use the drop-down menu and select 1000M
Network Adapter 2, then set the IP and DNS addresses for it.
IPv4 Settings
The CN9000/CN9600/CN9900/CN9950 can either have its IP address
assigned dynamically at bootup (DHCP), or it can be given a fixed IP address.
For dynamic IP address assignment, select the Obtain an IP address
automatically, radio button. (This is the default setting.)
To specify a fixed IP address, select the Set IP address manually, radio
button and fill in the IP address.
Note: 1. If you choose Obtain IP address automatically, when the switch starts
up it waits to get its IP address from the DHCP server. If it has not
obtained the address after one minute, it automatically reverts to its
factory default IP address, 192.168.0.60.
2. If the CN9000/CN9600/CN9900/CN9950 is on a network that uses
DHCP to assign network addresses, and you need to ascertain its IP
address, you can use the IP installer. See IP Address Determination,
page 135, for information.
The CN9000/CN9600/CN9900/CN9950 can either have its DNS server
address assigned automatically, or a fixed address can be specified.
For automatic DNS Server address assignment, select the Obtain DNS
server address automatically, radio button.
To specify a fixed address, select the Use the following DNS server
address, radio button and fill in the required information.
Note: Specifying for an alternate DNS Server address is optional.
