IP Gateway Cards
Physical Connections
When you place an IP gateway card, with its backplane module, in a slot in a router frame, the
card initially acquires a default IP address that is based on the slot number: the lower octet of
the IP address is the slot number (in the range 1 to 64). The default subnet is 192.168.3.xxx.
The two frames of an expanded NV8576-Plus have identical slot numbering. Therefore, using
the defaults for IP address will probably result in duplicate IP addresses on the network you
use to configure the cards. You must assign specific IP addresses to such cards.
You can change the IP address of an IP gateway card in the ‘Ethernet Settings’ page of MRC:
The IP address of the card, listed in this table, is the IP address given to the RJ-45 configuration
port of the card.
To assign the IP address, locate any devices of type ‘
Hybrid IP Gateway
’ and re-enter their IP
addresses as required. Also change the gateway IP address if necessary. The default subnet mask
is 255.255.255.0; you might have to change that to 255.255.254.0, or one with an even larger
device space.
After you change the IP address of IP gateway card, it will never be assigned the default address
again. The IP address assigned to the IP gateway card is actually stored in the card’s backplane
module. If you move the backplane module, the assigned IP address moves with it. The IP
gateway cards themselves are interchangeable, input with input, and output with output.
It is easy to forget the IP address of an IP gateway card. There is no simple way to determine
the IP address of a particular IP gateway card, particularly if your router has many of them.
If you do forget, open MRC’s ‘Ethernet Settings’ page and review the IP addresses of your IP
gateway cards. Also open MRC’s ‘Module Status’ or ‘Module Types’ page. Each of these pages
tells you in which slots your IP gateway cards are located, but does not tell you their IP
address. The ‘Ethernet Settings’ page tells you the IP address but does not tell you in which
slot the card (or really its backplane module) is located.
Perhaps the best way to remember an IP gateway card’s IP address is to label its backplane
module with the IP address.
You can upgrade the firmware in an IP gateway card the same way you upgrade any other I/O
card. Refer to the
MRC User’s Guide
for information.
