Xedge Chassis Systems

Craft and Alarm Connections

At the rear of the chassis, the front panel of the System Management Module provides connectors
for craft and alarm connections:
• Two DB9 ports (MANAGER and MGR STBY) provide local craft access via an
asynchronous terminal.
• One DB-25F connector is used for contact alarms.
Note
For pinouts and connection parameters on the SMM craft ports and the alarm connector, refer to Chapter 7,
System Management Modules .

AC Chassis Power Connections

Note
When connecting the AC power cord(s) to the unit, ensure the power cord retainer is fully open before
inserting the cord. Insert the cord firmly. The power cord must be fully inserted before tightening the power
cord retainer. Ensure the AC power plug "bottoms-out" in the AC power receptacle on the unit.
Note
If you have a power cord with a "molded ring" about 1-inch from the end of the female plug, the "molded
ring" must be inside the power cord retainer (not visible) when the plug is fully inserted in the unit's AC
power receptacle.
Each Xedge 6280 AC chassis is equipped with two AC power cords (US 120 VAC). Export power
cords are optional.
Plug the appropriate end into the AC receptacle of the power input module and plug the other end
into a polarized outlet that provides the required AC power. For AC mains redundancy, each power
input module should be connected to a separate AC source to protect against line input failure. On
the AC input PIMs, the power cord retainer should be used to secure the modular power cord
(supplied) and prevent accidental disconnection.
The AC power source should not be under switch control. If the Xedge 6280 is connected to other
equipment, it should be powered by the same AC source as that equipment to prevent large
circulating currents induced by differences in ground potential. If it is impossible to determine
whether the equipment is powered by the same AC source, verify that a potential difference of less
than 0.25 V rms exists between the grounding circuits of the respective power outlets.
WARNING
disconnect both power cords before attempting any service.
