Slide 1 of 1 Purpose: This slide describe the Cat1900 switch startup procedures. Emphasize: This slide states the tasks that students will be doing for one of the lab exercise in this module: Tasks - Start the switch, check POST LED display lights, set up required parameters, check initial configuration messages. Present this page as a listing of the major activities that your students will learn about in the next several page, and then practice doing with the lab. The item number 1 issue of preparation should have been completed with the last chapter. This juncture in the chapter is a good place for you to make sure that these preparations have indeed been done in all the work groups. Point out with the item number 2 issue that the Catalyst 1900 switch does not have a power on switch. Plugging in the power cable has the result of powering up the switch. For item number 3, transition to the next page for presentation details. Slide 1 of 1 Purpose: This slide describe the LEDs on the Cat 1900 switch. Emphasize: Refer to the table in the student guide for presentation details. Students will not be able to try out the various port LED display modes until they have powered up their switch. So tell your students to put a place holder on this page so that they can return to this student guide page. Before students can see the three port LED display modes, they will first see the port LEDs indicate Power-on Self-test (POST). POST indications on the switch port lights is your next topic. Slide 1 of 1 Purpose: This slide describe the POST on the Cat 1900 switch. Emphasize: As you present this, the bullet points are a like a flow chart of events, tests, and alternate outcomes (depending on test failure or completion without failure). The Catalyst POST is executed only when the switch is powered up and needs to verify that the hardware can properly function. This slide covers the LED perspective of initial start up. For another perspective of initial start up, refer
