CAUTION: In accordance with FCC Rules, Part 68.218(b), you must notify the
telephone company prior to disconnecting this product.
Power Connection
The POWER port is an eight-pin circular mini-DIN connector that connects
the autoranging 100–240 VAC external power supply to the unit. The FSM is
intended to be used with a UL Listed/CSA Certified Class 2 power supply
with a minimum output rating of 4.0 A at +5 VDC. The unit has no power
switch.
Figure 1.3 FSM Power Supply Unit
When power is applied to the unit, the front panel indicators flash for
approximately 10 to 15 seconds as the unit initializes. The green
POWER
LED on the front panel will remain illuminated as long as the unit receives
power. This LED turns amber when the unit is in test mode.
CAUTION: Always plug the external power supply into a grounded power outlet.
