44Engineering guidelines

When there are multiple ICBs (that is, more than three) and the BUI is used frequently, the BUI traffic can load the E-LAN, so it may be better to connect the cards to the C-LAN.

The ICB has a broadcast-storm protection mechanism: it shuts off the LAN port (temporarily) when traffic is too heavy. Nortel Networks recommends that the ICB be put in a “quiet” LAN segment to get a better response time.

Summary of LAN installation information

Use the following steps when installing and configuring the LAN:

1Determine whether the ICB is to be accessed from the World Wide Web.

2If yes, coordinate the firewall configuration with your IS group according to Table 3 on page 41.

3Determine what is the physical connection point of the ICB. Note these requirements: 10Base-T or 100Base-T, full-duplex.

4Get the following ICB IP parameters from your IS group: IP address, gateway address, and subnet mask.

5Get the Mail Server IP address from your IS group. Confirm that the ICB is allowed to access this server by SMTP.

Testing:

Use the following steps to test the LAN configuration:

1After the ICB is installed and the IP parameters are configured, try to “ping” from any host in the C-LAN to the ICB or from the ICB to a host on the C-LAN.

2In the case of World Wide Web access, try accessing the ICB from a browser (HTTP access).
