6.1.1
The following are points to observe before starting the switch:
- Verify the cable
and console connection.
- Attach the power
cable plug to the switch power supply socket.
- Observe the boot
sequence:
- LEDs on the
switch chassis
- Cisco IOS
software output text
- System startup
routines initiate the switch software
- Initial startup uses default configuration parameters

This page will explain the features, functions, and startup of
switches.
Switches are dedicated, specialized computers that contain a central processing unit (CPU), random access memory (RAM), and an operating system. As shown in Figure
, switches usually have several ports that
hosts can connect to, as well as specialized ports for the purpose of
management. Switches can be managed and the configuration can be viewed and
changed through the console port.
Switches typically have no power switch to turn them on and off. They simply connect or disconnect from a power source.
Several switches from the Cisco Catalyst 2900 series are shown in Figure. There are 12-port, 24-port, and 48-port
models. The top two switches in Figure are fixed configuration symmetrical switches
that offer FastEthernet on all ports or a combination of 10Mbps and 100Mbps
ports. The next three switches are asymmetrical models with two fixed fiber or
copper Gigabit Ethernet ports. The bottom four switches are asymmetrical models
with modular Gigabit Interface Converter (GBIC) slots, which can accommodate a
variety of copper and fiber media options.
The next page will discuss LED indicators on a switch.
