Port Locations
This section describes the port locations and numbering on the switches.
10/100 and 10/100/1000 Ports
The 10/100 and 10/100/1000 ports are configured in vertical pairs. Each vertical
pair has two Link Status LEDs below it. The LED on the left is for the top port;
the LED on the right is for the bottom port. For example, LED 1 is for the upper
port (port 1) and LED 2 is for the bottom port (port 2).
Embedded management

processing module
• Redirection of traffic from any port to a “sniff” port. (Any switching
port can be designated as a “sniff” port.)
