View source for Using 56k cards instead of serial cards

In some of our lab rooms you will find 56k cards instead of serial cards. Because we frequently plug and unplug these connections the 56k cards (with RJ-45 connectors) are more reliable and don't wear out as fast as the serial cards do. There are a few changes you need to be aware of though when using these cards.

=Different Port Naming=
Because the regular serial cards have two ports on one card they are identified as Serial0/0/0 and Serial0/0/1. Because each 56k card has only one port on it they are identified as Serial0/0/0 and Serial0/1/0. See the table below for a mapping:
