Phase 1: Making the connection

Cobalt Qube 3 User Manual 17

• If the Qube 3 auto-conﬁgures successfully, it acts as a DHCP server and

assigns to the clients IP addresses in the range 10.6.18.30 through

10.6.18.249, a subnet mask of “255.255.255.0”, a primary DNS server

address of “10.6.18.1” and a gateway or router address of “10.6.18.1”.

• Once you have completed the browser-based setup of the Qube 3, change the

TCP/IP settings for the clients on your network to “Use a DHCP server”

(Apple) or “Obtain an IP address automatically” (Windows).

Continue the setup process with “Phase 2: Setting up with the Web browser” on

page 20.

Conﬁguring the Qube 3 manually

If the Qube 3 is unable to ﬁnd a DHCP server on the network and you do not

choose the auto-conﬁguration option, the LCD display reads:

PRIMARY IP ADDR:

00.000.000.000

A blinking cursor appears on the second line of the LCD display. The following

steps explain how to enter the required network information for the primary

network interface. The secondary network interface is conﬁgured through the

Web browser as described in the next section.

☞

Important: In this phase, you conﬁgure only the primary network

interface. To complete this phase, you must know:

• the IP address assigned to the Qube 3

• the subnet mask of your network

✍

Note: A gateway or router address is not required for a Qube 3 that

is only connected to a local area network (LAN). If you connect to

another network through the Qube 3, you require a gateway

address. If you connect to the Internet with a modem, you do not

require a gateway.
