• The Power LED remains on.
• The Fault/Locator LED stays off.
• The port LEDs on the front of the switch go into their normal operational mode:
◦ If the ports are connected to active network devices, the Link/Act LEDs stay on or may be blinking
to indicate port activity. The Spd LEDs turn on for 1000 Mbps links, blink for 100 Mbps links, or stay
off for 10 Mbps links. On the PoE+ switches, the Mode LEDs behave according to the mode
selected. In the default mode (Spd), the Mode LEDs should be on for 1000 Mbps links, blink for 100
Mbps links, or stay off for 10 Mbps links.
◦ If the ports are not connected to active network devices, the Link/Act and Spd LEDs will stay off.
If the LED display is different than what is described above, the self test has not completed correctly.
Refer to Troubleshooting on page 27 for diagnostic help.

3. Mount the switch
The switch can be mounted in these ways:
• on a horizontal surface
• on a wall
• under a table
• in a rack or cabinet
Rack or cabinet mounting
The switches are designed to be mounted in any EIA-standard 19-inch telco rack or communication
equipment cabinet. Note that the mounting brackets have multiple mounting holes and can be rotated
allowing for a wide variety of mounting options.
WARNING:
For safe operation, please read Installation precautions on page 14 before mounting the switch.
NOTE:
The screws supplied with the switch are the correct threading for standard EIA/TIA open 19-inch racks.
If you are installing the switch in an equipment cabinet such as a server cabinet, use the clips and
screws that came with the cabinet in place of the screws that are supplied with the switch.
Complete the following step 1 to attach brackets to the switch. Then, plan which four holes you will be
using in the cabinet and install all four clips. Then proceed to step 2 to install the switch in the cabinet.
Procedure
1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the switch with the
included 8-mm M4 screws.
3. Mount the switch 19
