Corrections and Additions to the User Guide 3 Bay NetWorks Centillion 100 ATMSpeed Switching Modules ■ Do not change the ILMI VPI/VCI parameter in the ATMLink install program, because the Centillion switch accepts only the default value (VPI = 0, VCI =16). ■ The ATMLink 155 PCI NIC’s Resilient Server Architecture (RSL) feature will not work properly with the Bay Networks Centillion 100 switch if the switch uses UNI signaling version 3.1.
4 RELEASE NOTE FOR THE 3C975 ATMLINK 155 PCI NETWORK INTERFACE CARD The No. of NICs Installed is the total number of ATMLink NICs installed in the system. The Max. No. of ELANs Among the NICs is the number of ELANs on the ATMLink NIC that has the most ELANs. Round up the result to the first integral multiple of 16. When NICs with different maximum frame size values are installed, use the larger value.
Novell NetWare Considerations 5 Novell INETCFG Utility The Novell INETCFG utility views each ELAN as Ethernet even if the linktype parameter has been set to token ring. An LDI file (3975.LDI) that allows token ring ELANs to be configured correctly with the INETCFG utility is available on the 3Com Bulletin Board Service (3Com BBS), FTP server, and the 3Com World Wide Web site support index for the latest adapter files (www.3com.com).
