As Figure 1"1 illustrates, a LANIC card connects to the IEEE 802 LAN through an IEEE 802.3 card edge connector cable, an Attachment Unit Interface (AUI) cable, and a Medium Attachment Unit (MAU).

Figure 1%1. HP 1000 A%Series Connected to an IEEE 802.3 LAN

There are several system requirements associated with each LANIC:

Select Code

The select code is an octal number that is set by switches located on

 

the LANIC. Each LANIC card (or any I/O card for that matter)

 

installed in a host computer must have a unique select code (see the

HP 12076A LAN/1000 Link Local Area Network Interface Controller Installation Manual, part number 12076"90001, for switch location and setting information).

Logical Unit Numbers Each LANIC card installed in a host computer requires one logical unit (LU) number. This number is unique in the host system and is set during system generation where it is mapped to the card's select code (see the HP 12076A LAN/1000 Link Local Area Network Interface Controller Installation Manual, part number 12076"90001, for additional information).
