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:
— Two dc input connector housings and six
contacts for the customer-supplied dc input
cable
— Four air filter bracket screws
— Two 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.

Introduction

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.
