LEDIndicators
The QSC QE 16/0 Ethernet hub uses front panel LED indicators to display its operating
status: power on, link & activity status, and collision. The LEDs can function as useful
troubleshooting aids.

FCC NOTICE: This device has been tested and found to comply with the limits for a Class Adigital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This device generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this device does cause harmful interference to radio or television
reception, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Connect the computer into an outlet on a circuit different from that to which the receiver is connected.
• Increase the separation between the computer and receiver.
• Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to
operatethe equipment.
FCC Compliance Statement: This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
