Paradyne COMSPHERE 3000 - Manual (Page 31)

COMSPHERE 3000 Series Carrier
3-4 December 1994 3000-A2-GA31-80
Optional fan modules provide cooling to the devices in
the cabinets for operation at high ambient temperatures.
An optional speaker panel provides audio monitoring
of any one Model 3811 or 3911 dial/lease modem
installed in the carrier. This panel enables audio signals
(e.g., dial tone, busy signal, and ringing) to be heard
during normal operations.
DSUs, DBMs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs,
MCMPs, and dial/lease modems can be managed from an
SDCP, a Network Management System (NMS), or both.
T1 CSUs and T1 DSU/CSUs are managed from an SDCP
or remote PC. An SDCP or NMS can manage up to eight
carriers and can control up to 128 compatible DSUs.
If more than one carrier is to be controlled by the
SDCP, and/or if an NMS is to control the carriers, an SDU
must be installed. The SDU then serves as the interface
that links the carriers together so that one NMS and/or one
SDCP can control the units in the cabinet(s).
NOTE
Although the SDCP is the last
piece of equipment installed in the
bottom of the carrier, the ribbon
cable should be installed before
installing the power transformer
unit; it must be plugged into the
backplane and run through the
built-in retainer clips to the SDCP
at the front of the carrier.
An alarm output is also available for connecting an
external alarm device to all 16 DSUs and/or dial/lease
modems in a carrier, or to an entire cabinet. It provides a
relay contact that reports device and network failures to
local alarm reporting networks in an equipment room. The
relay is capable of switching up to 30 watts (resistive
load), with a maximum voltage of 60 Vdc, and a
maximum current of 1 amp for switching and 2 amps for
the steady state.
Cabinet Unpacking and Setup
When shipped, COMSPHERE 72-inch cabinets are
packed in cardboard shipping containers secured to
wooden pallets. The shipping containers are bound with
plastic straps. Inside the shipping container, the cabinet
itself is strapped to the wooden pallet with plastic straps.
There is minimal clearance between the cabinet and the
shipping container, and the cabinet frame is not wrapped
in packing material.
Presetup Inspection
Before opening the shipping container, inspect it for
signs of damage. Specific signs to check for are major
tears or puncture holes on the sides of the container, splits
in the seams, corner damage or any additional signs of the
container having been dropped (badly damaged pallet,
etc.).
If the shipping container does show signs of damage,
report this immediately to your shipping representative
and also to your AT&T Paradyne representative.
Unpacking the Cabinet
Using a utility knife, cut all plastic straps surrounding
the container.
You will need to cut the container to unpack the
cabinet. When cutting the container, do not cut along the
container’s seams. Doing so may damage the cabinet
because of the lack of clearance.
Due to the bulk and weight of the cabinet, it is
recommended that you cut around the base of the
container to lift it off the cabinet. If your ceilings do not
provide enough clearance, you may have to tip the
container and cabinet sideways. You will need another
person to help you tip the container and cabinet, and pull
the container off.
Once the container is off, cut the plastic straps holding
the cabinet frame to the pallet. Remove the packing
material at the base of the cabinet and lift the cabinet to its
desired location. You will need a large dolly to help you
lift and move the cabinet to its planned location.
