Set Up the Switch
Prerequisites
• You need the hardware and software described in the “Hardware 
Requirements” section and the “Software Requirements” section in Chapter 1 
of the switch user guide.
• You need the Category 5 Ethernet cable that is shipped with the switch.
• You should disable any pop-up blockers or proxy settings in your browser 
software and any wireless clients running on your PC or laptop. 
Follow these steps:
Step 1
Make sure that nothing is connected to the 
switch.
Step 2
Use the supplied switch power cable to 
connect the switch to an AC power source.
Before proceeding to the next step, wait until 
the SYSTEM LED stops blinking green and 
becomes solid green. A solid green SYSTEM 
LED means that the switch is operating 
properly. 
The ADMIN LED should be blinking green. 
A blinking green ADMIN LED means that the 
switch does not have an IP address yet.
Troubleshooting:
If the SYSTEM LED does not blink green, does 
not turn solid green, or turns amber, contact 
your Cisco representative or reseller. The switch 
failed the power-on self-test (POST).
