5.6.1 How To Assign IPv4 Addresses for Multiple Internal Cards

For multiple cards, use of IPv4 is more complicated, due to the need to specify, on the Host-PC, routing information for each individual SP-ICE-3 Card.

This requirement can be met by placing each card in a separate Sub-Net.

1. For each card, select an individual Sub-Net.

   • If we have, say, 3 cards in total, we might choose the sub-nets as follows:

     Card #	Sub-Net
     1	192.168.31.0 / 24
     2	192.168.32.0 / 24
     3	192.168.33.0 / 24

2. For each card, choose IPv4 addresses within the card's sub-net for both end-points of the Virtual Ethernet Cable between the Host-PC and the SP-ICE-3 Card.

   • Continuing our example, we might choose the end-point addresses as follows:

     Card #	Card End-Point	Host-PC End-Point
     1	192.168.31.1	192.168.31.2
     2	192.168.32.1	192.168.32.2
     3	192.168.33.1	192.168.33.2

Having chosen IPv4 addresses for our cards, we now have to assign them to the end-points both on the cards themselves, and on the Host-PC.

1. Manually assign the chosen IPv4 address and netmask to the SP-ICE-3 Card:

   • Access the card's WebInterface (see: 17.2 How to Open the Card's Web Interface).

   • On the NETWORK page, enter the IPv4 address and netmask, for eth1, which is the card's end-point of the Virtual Ethernet Cable.

     • Thus for our example, IP Address = "192.168.3x.1" and Netmask = "255.255.255.0",

       where x designates the chosen sub-net for the card.

     Please also refer to:5.5.3 Manually configuring the Card's IPv4-Address seen by the Host.

2. Reboot the SP-ICE-3 Card.

   Important
   Be aware that once the card reboots, you will temporarily be unable to make further contact with it from the Host-PC until you have completed the rest of the procedure.

3. Manually assign the chosen IPv4 address and netmask to the Host-PC's end-point of the Virtual Ethernet Cable:

   • For our example, IP Address = "192.168.3x.2" and Netmask = "255.255.255.0",

     where x designates the chosen sub-net for the card.
