2-14 CHP Max™ Headend Optics Platform Chassis, Controllers and Power Supplies Rev D
➤ To install the Power Supply module
1. If the CMM or SMM module is installed, press upward on the latch release on the
front panel and slide the module out the front of the chassis.
2. Position the Power Supply module with the multi-pin DC/Communication connector
toward the bottom.
3. Slide the rear (side with power and multi-pin connectors) of the Power Supply
module(s) into the chassis. Retaining tab snaps into place to secure the module.
4. Connect the appropriate AC power cord based on installation site to the IEC 320-C14
AC power cord connector on the rear of the Power Supply module. Refer to Table 3.1
on page 3-2 for the appropriate power cord.
5. Connect the power plug of the AC power cord to an AC receptacle (wall outlet).
Installing an Application Module
Modules currently available are listed in Table 2.7 on page 2-15.
➤ To install an application module
1. Refer to the system/headend map for the slot location of the application modules.
Note Do not install an AC Power Supply module (P/N CHP-PS/AC1 or CHP-PS/AC1-Q)
in a chassis that contains a DC Power Supply module (P/N CHP-PS/DC1 or
CHP-PS/DC1-Q). The 3.3V
DC outputs will not current share and false alarms may be
generated.
Note Modules can be installed and removed with the chassis powered
(hot-swapped).
Note The Power Supply module(s) must be installed before the CMM or SMM
module is installed.
Note While a single power supply will operate in either the upper or lower bay, the
Craft Management Software identifies the upper bay as slot 11 and the lower as slot
12.
Note The CHP-PS/AC1 or CHP-PS/AC1-Q AC input power supply includes a power
cord for 115V
AC United States installations.
CAUTION Some components are sensitive to electrostatic discharge (ESD)! Use a
grounding strap to prevent damage to electronic components by ESD. Do not touch
any components not specifically referred to in these instructions.
CAUTION Refer to the ARRIS Fiber Care and Cleaning Guide, P/N 1506507, for
important guidelines to follow when installing fiber optic cable.
Note Modules can be installed and removed with the chassis powered
(hot-swapped).
