Connectors, Controls, and Indicators
On the ACU-5000 front panel are the power on/off switch, a handset port, four indicator LEDs
(Signal/COR/PTT/Status), a USB connector, a 3.5 mm external speaker connector and volume
& mute controls. Also (on the rack mount version only) are 3.5 mm microphone and headphone
jacks.
The power switch is an illuminated rocker switch for quick visibility of power status.
The tabletop version has four LAN ports on the front and none on the rear panel while the rack
mount version has one in the front and one on the rear. The LAN ports are all RJ-45 connectors
and any or all may be used interchangeably, as with any Ethernet switch.
Power, radio, and PSTN connectors are all on the rear panel, and a small access hole through
which the unit’s reset switch can be activated. The PSTN ports use standard RJ-11 jacks (labeled
PSTN 1 through 3), and the radio (four-wire) connectors are standard RJ-45 jacks. The LEDs on
the RJ-45 connectors are illuminated to indicate active COR (amber) or PTT (green).

Safety Precautions and Procedures
The ACU-5000 is operated by a +12 VDC power supply and therefore any high level power
supply voltage exists only on the AC input side of the power supply. Standard precautions relative
to 115 or 230 (nominal) AC wiring applies. Caution should also be taken with the PSTN input
lines, as a high DC voltage “ring voltage” may be applied by the telephone system. The same
cautions apply as when dealing with any telephone system equipment.
Note: The ACU-5000 contains no user-serviceable components and
there is no reason to remove the unit’s top cover.

Maintenance
The ACU-5000 contains no user-serviceable internal components, and no maintenance is
required other than to ensure that the fans are clean and all ventilation holes remain unobstructed.
