4.4 POWER CONNECTION

Universal AC Power (100-240VAC)

The Model 1089 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 1089 by means of a barrel jack on the rear panel. Many international power cords are available for the universal power supply (Please refer to Appendix B for country-specific power cords.

The Model 1089 powers up as soon as it is plugged into an AC outlet--there is no power switch.

120 VAC Power (US)

The 100-132 VAC adapter supplied with the U.S. version of the Model 1089 is a wall mount type and may be plugged into any approved 120 VAC wall jack.

230 VAC Power (International)

The 230 VAC adapter supplied with the International version of the Model 1089 is a wall mount type and may be plugged into any approved 230 VAC wall jack.

DC Power

The 36-60 VDC DC to DC adapter supplied with the DC version of the Model 1089 plugs in a DC source (nominal 48VDC) and plugs into the barrel power supply jack on the rear of the 1089/I. Please refer to Figure 5, below, to make the proper connection.

5.1 POWER-UP

Before applying power to the Model 1089, please read Section

4.3and ensure that the unit is connected to the appropriate power source.

5.2 LED STATUS MONITORS

The Model 1089 features six front panel LEDs that monitor con- nections on the DSL and 10BaseT links, signaling, error and test modes. Figure 6 (below) shows the front panel location of each LED. Descriptions of each LED follow Figure 6.

Figure 7. Model 1088 Front Panel

DSL Link (Active Green) Solid green (On) indicates that the end to end DSL Framer Link is up, signifying that the link across the DSL span is active. The DSL Link LED is Off when the link is down.

Status Blinks yellow from one to eleven times to indicate system status. Each pulse pattern is separated by a 2 second “off” period. Greater pulse patterns have higher priority (buffer saturation has greater priority than an empty MAC table). Valid system statuses are:

1 pulse	=	system status is okay
2 pulses	=	no MAC entries in the MAC
		Address Table
3 pulses	=	Clear to Send (CTS) or Carrier
		Detect (DCD) from base unit are not
		asserted
4 pulses	=	IM1/I buffer is saturated
5 pulses	=	WAN receive frame(s) too large
6 pulses	=	WAN receive frame(s) not octet
		aligned
