Configuring the Layer 2 Switch

The 3300 ICP requires a Layer 2 switch between its controller and the

network. The internal Layer 2 switch in the CXi and MXe must be

programmed with an IP Address in the same subnet as the RTC IP

Address, or the switch will not operate properly. Do this by completing the

System IP Configuration form, and then reboot the system.

1. Connect an Ethernet cable between the Layer 2 switch on your

network and the leftmost available Ethernet port on the controller (port

17 on the CXi and the left Gigabit port on the MXe). Use a

straight-through cable for the CXi and MXe and a crossover cable for

all other controllers.

2. Program the Layer 2 switch with the appropriate settings (see

“Network Configuration Examples” on page 317 for more information).

- See your IT administrator for information to set up and program a

DHCP server. We recommend that you use the controller’s internal

DHCP server to provide a static IP address to the E2T.

3. If you are not using the controller’s DHCP server, disable it in the

DHCP Server form.

Note: The 16 10/100 Mbps ports are disabled on the CXi during bootup;

likewise, the right-side Gigabit port on the MXe.

Tip: Refer to the System Administration Tool Online Help for detailed

instructions for programming the IP Network Configuration forms associated

with the CXi and MXe.

Tip: For an MX or 100-user system, move the Maintenance PC

Ethernet connection from the controller to one of the Layer 2 switch

input ports, and connect the Layer 2 switch to the leftmost Ethernet

port of the controller. You can do the same for an LX, 250 and a

700-user system, if desired.

Tip: Typically, in a VLAN environment, an access port is used to connect

the Layer 2 switch to the controller, and trunk ports to connect the Layer 2

switch to the IP Phones.

Tip: IP trunks cannot work through the WAN port.

Tip: See “Configuring a Windows 2000 DHCP Server (prior to Release 7.0)”

on page 308 for information on programming 3300 ICP DHCP settings on a

Windows 2000 DHCP server.
