VENTILATION REQUIREMENTS
IMPORTANT: The SMS3 should be situated so that its location or position does not interfere with its
proper ventilation. Do not block vents above or to the sides of the unit, as it requires ventilation to
the sides and above for proper operation. Do not place the SMS3 above a heat-generating compo-
nent such as an audio amplifier, and do not place a heat-generating component directly above the
SMS3.
Be sure to leave at least 2 inches of space to the sides of the unit with open air flow
above. A single-space rack mount vent or about 1.75 inches must be kept clear above
the unit.
AUTOMATIC THERMAL SHUTDOWN
The SMS3 is equipped with a thermal threshold shut down that is activated through the server’s soft-
ware. If a thermal shut down occurs, the unit will emit a warbled beep for five seconds, then will
power off. If this occurs, do not re-power the SMS3 until sufficient cooling time (at least 10 minutes)
has passed. If the unit is powered while temperatures are still above threshold, the SMS3 will repeat
the beep and shut down again.
SMS3 INSTALLATION QUICK LOOK
1. Connect SMS3 to a controller amplifier
2. Connect SMS3 to LAN
3. Connect SMS3 to video display
4. Connect SMS3 to power
SMS3 LOCAL AREA NETWORK (LAN) CONNECTION QUICK LOOK
1. Connect SMS3 to a router with DHCP (Dynamic Host Configuration Protocol)
2. Check LEDs on Ethernet connector (back of SMS3). A solid green light indicates a physical
network connection; a flashing yellow LED indicates network activity.
3. Obtain SMS3 IP address on LAN through video display (page 21)
4. From a computer networked on the same LAN, use a web browser to locate the SMS3
(IP address) on the LAN
TROUBLESHOOTING NETWORK PROBLEMS
1. Are the LEDs on the Ethernet connector (back of SMS3) illuminated?
If NO, troubleshoot cable and connection. This LED lights up when ANY network is connected
2. What does the SMS3 report as its IP address (page 21)?
If no IP address appears, then DHCP is not working. Refer to router instructions.
