Overview

The CO Power Unit consists of one power module in a CO power tray. When installed, the CO Power Unit provides low voltage dc power to the DCEs in the carrier. This chapter provides information on how to install the CO Power Unit into a COMSPHERE 3000 Series Carrier.

Installation Considerations

The CO Power Unit is shipped with one power module and operates in Basic mode. With an optional second power module the CO Power Unit can be configured to operate in either Independent mode or Redundant mode. If you order a second power module for your CO Power Unit, you must determine the mode in which you wish to operate before installing the CO Power Unit.

NOTE

The CO Power Unit installation procedure must be performed by a qualified service personnel.

In addition, if you want to forward alarms to a 6800 Series Network Management System (NMS), you must connect the CO Power Unit to the external leads of a Modular 3611 DSU. Model 3151 CSUs and Model 3161 DSU/CSUs do not support forwarding of CO Power Unit alarms to a 6800 Series NMS. To access these external leads, use an NMS adapter cable to connect the external leads of a Modular 3611 DSU to the CO Power Unit.

This section describes the three modes of operation and provides information you need to know in order to send alarms to a 6800 Series NMS.

Basic Mode of Operation

The CO Power Unit with one power module operates in Basic mode. In this mode of operation, the single power module supplies power to the entire carrier.

When stacking multiple carriers equipped with CO Power Units with single power modules, you must install the power module in each of the CO Power Units in alternating sequence (that is, left side, right side, left side, right side, etc.) for proper cooling. For example, if the CO Power Unit in the bottom carrier has its power module installed in the left side of the CO power tray, the carrier
