Quick Install Guide
16-Port RJ-45 + BNC/AUI Ethernet Hub for QSControl2™ Audio Systems
Introduction
The QSC Audio Model QE 16/0 is a multi-port Ethernet hub that allows flexibility and versatility in
audio control LAN topologies. It has 16 RJ-45 ports for unshielded twisted pair (UTP) network
cabling, as well as a BNC/AUI port for direct connection to network segments using different media.
The QE 16/0 hub constantly monitors each port for signal quality and will disconnect (partition) a
device producing noise or excessive collisions and will then automatically reconnect it when the
offending condition clears.
Hub Features (see diagrams on previous page)
➀ Power LED
➁ Collision LED
➂ Link/Activity LED
Indicates the hub has AC power and is turned on.
Indicates a packet collision.
A steady green light indicates a good cable link between the hub
and the network device connected to that port;
A blinking green light indicates network activity.
Slide switch: left = Normal mode; right = Uplink mode
Configurable as 16 normal UTP ports
➃ Uplink Switch (Port 16)
➄ RJ-45 Ports
or 15 normal UTP ports plus one UTP uplink port (Port 16).
BNC or AUI for connection to a LAN segment using different
media.
For AC power cord. The internal power supply automatically
senses 90–250 VAC.
➅ BNC and AUI Ports
➆ IEC connector
➇ ON/OFF power switch
Features:

Allows interconnection of Thin (BNC) and UTP segments without other intermediate media
conversion devices.
Connects up to 16 UTP 10BASET segments and one Thin (BNC) and/or one Thick (AUI) Ethernet
segment.
Detects network collisions and alerts all participating host devices. Amplifies and re-times
received signals and transmits the signals to attached host devices in the event of a collision.
Preamble regeneration, signal retiring and restoration, extension of fragmented packets and
jabber function for automatic partitioning to isolate network failure.
Global power, collision, partition LEDs and individual port Link/RX or Link/Activity LED to aid
network diagnosis and management.
Performs full 10 Mbps Ethernet multi-port repeater functions and complies with IEEE 802.3
standard for 10BASET Unshielded Twisted Pair (UTP) and 10BASE2 Thin Coaxial (BNC) or 10BASE5
Thick Coaxial (AUI).

LED Indicators
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.
Troubleshooting
The table below lists the LED indicators of the QE 16/0, what they should display in normal
operation, and what might cause an abnormal indication.
LED Indicator
Normal indication
What it tells you
Power (green)
On
If it’s not on:
1.) Make sure the AC power cord is properly
inserted into the hub and the AC outlet.
2.) Make sure the power switch is on.
Link/Activity (green) On or flashing
If the LED glows green steadily, it indicates that the
port detects the 10BASET network carrier signal. If
the LED flashes, it indicates network activity—i.e.,
the port is transmitting or receiving data.
Collision (red)
Off
If the LED flashes, it indicates that 2 or more
network nodes have tried to access the network
simultaneously. Occasional occurrences are normal
and will not affect network performance. If the LED
flashes repeatedly or continuously, one or more
nodes may be malfunctioning, or there may be other
devices utilizing the network heavily.
