- [Instructor] I'm going to go ahead and start
by exploring the physical components
of the 2950 Catalyst Switch.
On the backside of the switch
you will see an AC power connector.
This is where the power from the wall
will plug into the switch.
There's an RJ45 console management port,
a fan exhaust,
as well as an RPS,
which stands for redundant power supply, connector.
On the front side of the switch
you see there's 24 Fast Ethernet ports.
They're numbered 1 through 24.
There's also, on the left-hand side
underneath the Cisco logo, the following mode LEDs.
There's the System which shows
if the switch is receiving power and functioning properly.
To the right of that is the RPS and it provides info
about the redundant power supply status,
if it's available and functioning.
Below that is the Stat, which gives us the status of a port,
the Utility, which displays the bandwidth
in use by the switch,
the Duplex LED,
which indicates whether or not the port
is in full or half-duplex mode,
the Speed which shows the port operating speed,
and below that is the Mode button,
and you would press the Mode button
to cycle through the different LEDs
so that you can get information about the status
of the functioning of the switch.
And above each switch port is a little LED,
which indicates whether or not that switch port
is up and functioning
and whether or not traffic is passing through that port.
