Installation
Refer to the preceding figure and follow these instructions:
1. Push the connector on the alarm cable into header J4 on the alarm panel. The cable connector
and header are keyed—they will only fit together in the proper direction. The retaining clips
automatically close as the connector is seated.
2. Gently squeeze the retaining clips towards each other to ensure that they are fully closed and
the connector is fully seated.
3. Guide the tabs at the bottom of the alarm panel into their slots in the chassis.
4. Push the top of the alarm panel towards the top of the chassis and secure the alarm board with
the two captive screws provided.
AC or DC Power Distribution Panel

Warning
Warni ng
This subassembly is not a field-replaceable unit. Regulatory guidelines do not allow
the replacement or repair of CPX power distribution panels by the customer.
Replacement and repair must be managed by the Emerson Field Service Organization
(FSO) so the warranty and regulatory labels are not voided. Please contact your
Emerson sales representative.
The power distribution panel is not hot swappable in CPX8216 platforms. Removing
the power distribution panel disconnects all of the power supplies from the input
power. For supporting information on the power distribution panel, refer to Chapter 6,
Chassis Operations.
Warning
Warni ng
To prevent serious injury or death from dangerous voltages, before removing the
power supply, set the power switch to OFF (O), disconnect all power cords from their
sources, and allow one minute for the capacitors in the power supply to discharge.
Warning
Warni ng
Disconnect power supply before servicing.
Service personnel: If using more than one DC power circuit, disconnect all power
sources before installing or servicing any components internal to the CPX enclosure.
For important grounding information for a DC power source, please read the
instructions in Connecting the Chassis Cables on page 40.
Note The DC power inputs must only be attached to approved Telephone Network Voltage
(TNV) or SELV (Safe Extra Low Voltage) branch circuits. Branch circuits must comply with all
requirements called for in these safety standards: IEC 60950, EN 60950, CAN/CSA-C22.2 No.
60950-00. Attaching inputs to non-TNV/SELV approved power sources will cause the system
to fail compliance with safety regulations.
