Remember the base IP address is the address initially programmed into the P2K system
controller(s) – either from the factory or, if the factory address is totally out of range, through a
Windows IP configuration operation - and it becomes the nomenclature used to identify the
system controller on the network.
In some applications it may be necessary to set the base IP address of the PERC2000 controller to
a value other than the factory assigned address to accommodate your particular installation; this is
easily accomplished through the P2K GUI. Changing the IP address may be required for a
number of reasons; for example, in new installations the IP address of system components, such
as the PERC2000, occasionally need to be set differently from the factory ship configuration to
avoid addressing conflicts with other network hardware.
Assume you are installing a new PERC2000 system, with a redundant controller card, and wish to
use the IP addresses 192.168.5.101 and 192.168.5.102 for the controllers, rather than the default
values set by the factory. Using the P2K GUI you would change the base address to
192.168.5.101. When the “new” address is saved to the controllers, it is simultaneously written to
both the primary and redundant controllers in the system. Saving the new address will cause the
system controllers to re-boot and thereby assume their “new” unique address derived from the
changed base address.
The base IP address of the P2K system controllers may be set to virtually any value that best suits
your network, with a few caveats:
• You may set the first three octets of the IP address to any values needed for your
installation.
• You may assign any valid value (1 thru 254) to the fourth octet, keeping in mind numbers
0 (zero) and 255 are not valid for use.
• When determining the number for the fourth octet you must dedicate a block of 2
consecutive numbers, if a secondary controller is used. The number you assign as the
base IP address will become the operating IP address of the primary system controller,
and will be incremented by one when assigning the IP address to the redundant system
controller.
The following steps guide you through the procedure to enter a new base IP address value to your
P2K system controllers:
• Launch the P2K GUI application from the desktop icon or browse to the PERC2000.exe
file and double click to open the application.
• Click on the Help menu in the Windows™ menu bar and select the IP Config Utility
option from the menu as shown in Figure 5-3.
