Paradyne 3000 manual Carrier Installation, Cabinet Setup, Preinstallation Inspection, Procedure

Installation

Cabinet Setup

The cabinet is shipped from the factory with doors,

mounting rails, and two factory-installed ac power strips. Cabinet setup requirements are, therefore, minimal and consist of leveling the cabinet once it is in place at your site and, if needed, reversing the cabinet doors.

Leveling the Cabinet

There are four adjustable leveling screw feet at the bottom of the cabinet; these screw up or down, enabling you to adjust the cabinet to a level position on the floor. You can use a level if desired, and you will need an adjustable crescent wrench to rotate the feet to level the cabinet.

To level the cabinet:

.Procedure

1.Place the level against the front door and adjust the leveling feet until the cabinet stands level vertically from front to rear.

2.Place the level against one cabinet side and adjust the leveling screws until the cabinet stands level vertically from side to side.

Reversing the Cabinet Doors

The cabinet's front and back hinged doors are installed on the cabinet frame at the factory to open left-to-right. You can use pre-drilled holes on the opposite side of the frame to reverse the door, allowing the door to open right-to-left.

To reverse a door:

.Procedure

1.Supporting the door, use a flat-blade screwdriver to remove the screws from the bottom hinge, detaching the hinge from the cabinet frame.

2.Supporting the door, remove the screws from the top hinge, detaching the hinge and the door from the cabinet frame.

3.Flip the door end-over-end.

4.Holding the door in position on the opposite side, align the hinge holes with the predrilled holes on the cabinet frame provided for this purpose. Then use the same screws to reattach the door by its hinges to the cabinet.

Carrier Installation

You will need a large, Phillips screwdriver to install the carrier in the cabinet and to install the power transformer unit under the carrier. A small, flat-blade screwdriver is required to remove and replace the cover plate or SDCP, and to install the 50-pin cable connectors.

Each carrier is shipped with the following associated equipment:

•Six cable ties

•Two fuses (spares)

•Four # 10-32 mounting screws

•Four cabinet (4000-B2-200) # 12-24 mounting screws and four speed nuts for use with other cabinets

•One jumper wire for the frame ground/signal ground

These items are bundled together in a plastic bag.

The carrier and its associated auxiliary equipment are designed to be mounted in cabinets.

The carrier is equipped with reversible mounting brackets (Figure 3-2) to allow installation in cabinets that are either 19 inches or 23 inches wide. These brackets are initially positioned to allow the carrier to be installed in a cabinet on 19-inch centers.

Preinstallation Inspection

Remove the carrier from its shipping container and check for physical damage. If the carrier shows signs of shipping damage, report this immediately to your shipping representative and also to your AT&T Paradyne representative. Otherwise, proceed with the installation.

The COMSPHERE 3000 Series Carrier, Figure 3-1, is designed to house T1 CSUs, T1 DSU/CSUs, DSUs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs, MCMPs, and dial/lease modems. The carrier is a metal enclosure that contains slots for installation of 17 circuit cards. The slot labeled SDU (Slot 0) is reserved for the Shared Diagnostic Unit (SDU); Slots 1 through 16 are for T1 CSUs, T1 DSU/CSUs, DSUs, DBM-Vs, DBM-Ss, DBM-Ds, TDMs, MCMPs, or dial/lease modems. Under each slot number (on the cover plate or SDCP) is a small area in which to write the circuit channel identification numbers.
