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

•Two backplane connector cable assemblies

•Two air filter brackets

•One installation kit which includes the following:

ÐTwo dc input connector housings and six contacts for the customer-supplied dc input cable

ÐFour air filter bracket screws

ÐTwo 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. To 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.
