Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product or included in the manual.

2. This product is intended to be used with a three-wire grounding type plug — a plug which has a grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by modifying the plug or using an adaptor.

Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the presence of earth ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician has corrected the problem.

If a three-wire grounding type power source is not available, consult a qualified electrician to determine another method of grounding the equipment.

3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from overheating, these slots and openings must not be blocked or covered.

4. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the power cord.

Safety Instructions

5. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel.

6. General purpose cables are provided with this product. Special cables, which may be required by the regulatory inspection authority for the installation site, are the responsibility of the customer.

7. When installed in the final configuration, the product must comply with the applicable Safety Standards and regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action prior to interconnecting the products.

9. In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:

— Never install telephone wiring during a lightning storm. — Never install telephone jacks in wet locations unless the jack is specifically

designed for wet locations.

— Never touch uninsulated telephone wires or terminals unless the telephone line

has been disconnected at the network interface

— Use caution when installing or modifying telephone lines. — Avoid using a telephone (other than a cordless type) during an electrical storm.

There may be a remote risk of electric shock from lightning.

— Do not use the telephone to report a gas leak in the vicinity of the leak.

Overview

The COMSPHERE –48 Vdc Central Office (CO) Power Unit is designed to provide low voltage dc power to any data communication equipment (DCE) operating in a COMSPHERE 3000 Series Carrier.

The –48 Vdc CO Power Unit (hereafter referred to as the CO Power Unit) consists of the following components:

• One CO power tray with mounted backplane

• One power module

• T wo backplane connector cable assemblies

• T wo air filter brackets

• One installation kit which includes the following:

— T wo dc input connector housings and six

contacts for the customer-supplied dc input

cable — Four air filter bracket screws — T wo nylon cable ties

You must supply the following related components:

• A second power module, if desired.

• One or two –48V power input cables. The required

number of input cables depends upon your configuration.

• One air filter, if needed.

• Alarm cables and NMS adapter cable, if needed.

These components are used to connect the CO Power Unit to a CO alarm system and/or a COMSPHERE 6800 Series Network Management System (NMS) through a Modular 3611 Data Service Unit (DSU).

(A Modular 3611 DSU has a row of contacts on the rear edge of the circuit card and is shipped with a rear connector plate. The rear connector plate allows the removal of a Modular 3611 DSU from the front of the carrier without first disconnecting the DTE cables at the rear of the carrier. The NMS adapter cable is only compatible with the Modular 3611 DSU. For more information on the Modular 3611 DSU, see the COMSPHERE 3600 Series Data Service Units, Models 3610 and 3611, Operator’s Guide.)

The total number of components required depends upon your configuration. The ACCULINK 3151 CSUs and 3161 DSU/CSUs do not support forwarding of CO Power Unit alarms to a 6800 Series NMS.

The CO Power Unit can send alarms to a CO alarm system and a 6800 Series NMS simultaneously. To connect to a CO alarm system, you need one customer-supplied alarm cable for each power module. T o forward alarms to a 6800 Series NMS, you need one Modular 3611 DSU (configured to forward alarms to a 6800 Series NMS) and one NMS adapter cable. You can also use a non-modular Model 3611 DSU, but you must build your own cable. This guide provides information on forwarding alarms to a 6800 Series NMS via a Modular 3611 DSU, but reminds you that a non-modular Model 3611 DSU can also be used.

Important

at the front of

Features

The CO Power Unit provides the following features:

• Enables DCEs supported by the COMSPHERE

3000 Series Carrier to operate in a –48 Vdc central office environment.

• Provides the following three modes of operation:

— Basic mode – the mode in which the single

power module supplies power to the entire

carrier. This mode of operation is the only

mode available for the CO Power Unit with one

power module.

— Redundant mode – the mode in which two

power modules supply power to the entire carrier. If one power module fails, the remaining power module assumes the full load of the carrier. To operate in this mode of operation, you must install an optional second power module in the CO Power Unit.

— Independent mode – the mode in which each

of the two power modules supplies power to one-half of the carrier. To operate in this mode of operation, you must install an optional second power module in the CO Power Unit.

• Provides forced air cooling for the carrier via a

–48 Vdc fan in the power module.

• Provides an optional air filter which prevents dust

from entering the CO Power Unit and the COMSPHERE 3000 Series Carrier.

• Detects power module and fan failures by

monitoring the power output levels and the fan’s low-speed sensor for proper operation of the power module. When a failure occurs, an alarm indication light appears on the power module’s faceplate.

• Sends power failure and/or fan failure alarms to a

CO alarm system and/or a 6800 Series NMS via a Modular 3611 DSU.

Figure 1-1 illustrates the CO Power Unit with one

power module in the left side of the CO power tray. In Basic mode, the single power module can be installed in either the left or right side of the CO power tray.

Figure 1-2 illustrates the CO Power Unit with two power

modules.
