• 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).
