Ip Information

This is where the CXC’s current IP Address Settings are displayed for the LCD menu. Scroll bars enable the user

to navigate the list of text items for viewing; i.e., IP Address, Subnet Mask, Gateway, and Ethernet/MAC Address.

For the web interface, the current IP Address Settings are found by clicking on the “View Live Status” link of the

Communications submenu.

Configuring IP Address Settings

This section discusses how to change CXC communications parameters in the IP Address section of the menu

(or web interface). See 6.8.3 and Figure 84. To save changes, refer to Section 4.9.

Obtain Address Automatically

If selected, this checkbox will enable the CXC to automatically obtain an IP address from a

DHCP server at system boot-up (if checked it will enable the DHCP client protocol).

Static Settings

All three fields in this area are only enabled if the “Obtain Address Automatically” checkbox is

not selected.

Ip Address

This field is the Static IP Address to use for the CXC device. The format of the IP address must

be a so-called “dotted quad” – that is a series of 4 values in the range 0-255 each separated by

a period. For example, an example of a dotted quad would be: “192.168.1.23”.

An incorrect example would be: “213.12.24.264” (264 is outside the range 0-255).

NOTE: The rules and restrictions for valid IP addresses are beyond the scope of this manual.

Check with the LAN administrator for details.

Subnet Mask

This field contains the dotted quad for the static Subnet Mask for the CXC.

Gateway

This field contains the dotted quad to specify the gateway to use for routing packets if the

destination IP address is not local.

PPP Connection Devices

One of two PPP Connection devices can be selected from a pull-down menu for HTTP web server connection:

Front Craft Port or Rear Modem Port (Figure 101). PPP connections over serial ports are mutually exclusive to

each other.

NOTE: The PPP connection for HTTP web server connection has no effect on enabling the HTTP web server for the

Ethernet port. The HTTP web server for the Ethernet port cannot be disabled.

8.2.1

Front Craft Port

Front Craft Port does not support modem connection. For most CXC models, it is used with NULL modem

connection for HTTP web server connection.

CAUTION

For the CXCI, do not connect anything other than the Alpha modem and Alpha-supplied DB-9

cable to the D-sub port on the front.

Rear Modem Port

Rear Modem Port provides three choices for installed modem; selected from a pull-down menu: Internal Modem,

External Modem, and NULL Modem. When connection is established, the HTTP web server, SMTP outbound

e-mail notification and/or SNMP dial out trap notification can be delivered through PPP.

Modem Init String needs to be specified in order to initiate external (remote) modem connection.

Rear Port Configuration

This section provides information on setting up and configuring the rear port modem device (or a direct null

modem serial cable connection) with the CXC to provide inbound web server support and/or outbound e-mail

alarm support and/or SNMP trap dial-out support. To save changes, refer to Section 4.9.

The Alpha Cordex Controller (CXC, Alpha P/N 018-557-20 or 018-587-20) supports connection to one of the

following:







Alpha-supplied internal modem daughterboard module (via rear RJ-11 jack), or

External AT-class V.34 or V.90 modem (via rear RS-232 serial port with DB-9 connector), or

Null modem direct cable connection (either front or rear RS-232 serial port) to a computer running Windows

2000.
