Cobalt Qube 3 User Manual 15

Conﬁguring the Qube 3 with a DHCP server on

the network

The Qube 3 ﬁrst checks to see whether a DHCP server is present on the network.

If there is a functioning DHCP server that is set up to serve leased IP addresses,

the Qube 3 conﬁgures itself with the information received from the DHCP server.

Once the boot process is completed, the top line of the LCD screen displays the

fully qualiﬁed domain name of the Qube 3 and the bottom line displays the

leased IP address.

☞

Important:

To function properly over long periods of time, the

IP address of the primary network interface on the Qube 3 must

remain ﬁxed, meaning that the DHCP server must not assign this

IP address to a different machine at a later date. Unfortunately,

some DHCP servers do not honor requests for permanent

IP addresses. As a result, your Internet service provider (ISP) or

network administrator may need to assign a different (and

permanent) IP address to the Qube 3. If so, you will need to change

the network conﬁguration information.

Coordinate any changes to the IP address, subnet mask or gateway

address with your ISP. If your Qube 3 is integrated into a larger

network, consult with your network administrator for this

information.
