4.3 POWER CONNECTION

4.3.1 Universal AC Power (100-240VAC)
The Model 1193 uses a 5VDC, 2A universal input 100-240VAC,
power supply (center pin is +5V). The universal input power supply
has a male IEC-320 power entry connector. This power supply con-
nects to the Model 1193 by means of a barrel jack on the rear panel.
Many international power cords are available for the universal power
supply (Refer to Appendix B for country-specific power cords).
The Model 1193 is ready for operation as soon as it is plugged
into an AC outlet. The unit does not have a power switch.
4.3.2 DC Power
The 36-60 VDC DC to DC adapter is supplied with the DC version
of the Model 1193. The black and red leads plug into a DC source
(nominal 48VDC) and the barrel power connector plugs into the barrel
power supply jack on the rear panel of the 1193. (See Figure 9).

Once the Model 1193 is properly configured and installed, it should
operate transparently. This section describes power-up, LED status
monitors, and the built-in loopback test modes.
5.1 POWER-UP
To apply power to the Model 1193, read Section 4.3, and be sure
that the unit is connected to the appropriate power source.
Set front panel switches to Normal. Then, plug the provided power
adapter (see section 4.3) into the rear panel outlet of the Model 1193
and then into an acceptable power outlet (AC or DC depending on the
model -UI or -DC). After both the local and remote Model 1193s are
powered up, a synchronization process will occur to establish a link. The
synchronization process should take approximately 5 seconds. Any time
one of the Model 1193s lose power (i.e., in a lightning storm), the local
and remote units will re-synchronize before they can resume data trans-
mission.
When the local and remote Models 1193 have established a link
and are passing reliable data, the following LED conditions will exsit:
· Fiber = GREEN
· E1 = GREEN
· LOS = OFF
· NS = OFF
· ER = OFF
· TM = OFF

5.2 LED STATUS MONITORS

The Model 1193 features six front panel status LEDs that indicate
the condition of the modem and communication link. Figure 10 below
shows the front panel location of each LED.
