3.6 Mounting the HOA 7100
The HOA 7100 can be mounted in a 19-inch equipment cabinet or a 19-inch
Telco rack. Mounting screws are thread-forming UNC #12-24. For best results,
always use screws provided by the rack manufacturer.
To insure the integrity of secondary grounding paths, paint and other non-
conductive surface coatings should be removed from the surfaces between the
mounting hardware and the framework or cabinet. The surfaces to be joined
should be cleaned and an anti-oxidant solution should be applied before
joining the surfaces.
3.6.1 Mounting the HOA 7100 in a 19-inch Cabinet
To mount the HOA 7100 in a standard 19-inch equipment cabinet:
1. Place the unit in the cabinet.
2. Remove the bezel from the HOA 7100 by grasping the ends and pulling
straight out.
3. Use four mounting screws to attach the mounting ears on the HOA 7100
front panel to the cabinet.
4. Replace the bezel by aligning the springs on the ends of the bezel with the
ball studs on the chassis, then snapping the bezel into place.
5. Visually inspect each key (button) on the front panel to ensure it is not
trapped under the edge of its hole. If a key is trapped, tap the key to allow
it to move freely.
3.7 Connecting Power
The HOA 7100 is available in an AC power model and a DC power model.
After mounting the HOA 7100 in a rack, follow the power connection
procedure below for the model that you are installing.
3.7.1 Connecting AC Power
The AC-powered HOA 7100 has one 110/220 VAC (50/60 Hz) input
connector that requires input voltage from 100 to 240 VAC, at 50 to 60 Hz
single phase. Selection switching over this range is automatic. The AC power
plug is located on the rear panel.
To connect AC power:
1. Connect the ground contact to ground. This is important for your safety.
The ground contact is located on the rear panel, as shown in Section
3.4 Rear Panel Diagrams on page 3-3.
2. Connect the power cord to a 110 VAC or 220 VAC (50/60 Hz) electrical
socket. (The AC-powered HOA 7100 features an auto-sensing power
supply.) The HOA 7100 boots up. It takes about 30 seconds for all systems
to operate.
CAUTION:
To avoid personal injury and damage to the equipment, use a
power outlet with a protective ground (third wire) contact.
