NEC DSX160 8 Slot Common Equipment Cabinet User Manual

1. Introduction

This manual provides essential information for the proper installation, configuration, and maintenance of the NEC DSX160 8 Slot Common Equipment Cabinet. This cabinet is designed to house various components of the DSX 160 telecommunication system, providing a structured and secure environment for your equipment.

The cabinet itself does not contain a CPU or power supply; these critical components must be purchased and installed separately to enable the full functionality of the DSX 160 system.

2. Safety Information

Always observe the following safety precautions to prevent injury and damage to the equipment:

• Ensure the cabinet is installed in a stable, dry, and well-ventilated area, away from direct sunlight, heat sources, and moisture.
• Before installing or servicing any components within the cabinet, disconnect all power sources to prevent electrical shock.
• Only qualified personnel should perform installation and maintenance procedures.
• Do not block ventilation openings on the cabinet. Proper airflow is essential for cooling the internal components.
• Use appropriate tools and follow all local electrical codes and regulations.

3. Product Overview

The NEC DSX160 8 Slot Common Equipment Cabinet is a robust enclosure designed to organize and protect the core components of your DSX 160 communication system. It features eight dedicated slots for various expansion cards and modules.

4. Setup and Installation

The installation of the NEC DSX160 cabinet involves mounting and populating it with the necessary system components. Remember that the CPU and power supply are separate purchases.

4.1. Site Preparation

• Select a location that is easily accessible for maintenance, has stable temperature and humidity, and is free from dust and vibrations.
• Ensure adequate space around the cabinet for ventilation and cable management.
• Verify that the mounting surface (wall or rack) can support the weight of the cabinet and all installed components.

4.2. Mounting the Cabinet

The cabinet can be wall-mounted or placed on a flat, stable surface. Use appropriate mounting hardware (not included) for secure installation.

1. Mark the drilling points on the wall according to the cabinet's mounting holes.
2. Drill pilot holes and insert appropriate wall anchors if necessary.
3. Secure the cabinet to the wall using screws, ensuring it is level and firmly attached.

4.3. Component Installation

After mounting, install the CPU, power supply, and other expansion cards (e.g., T1/PRI cards, IntraMail, doorbox modules) into the designated slots within the cabinet.

1. Open the front access panels of the cabinet.
2. Carefully insert the CPU module into its primary slot, ensuring it is seated correctly.
3. Install the power supply unit, connecting it to the CPU and other components as per the specific instructions for those modules.
4. Insert expansion cards into the available 8 slots, aligning them with the connectors and securing them if required.
5. Connect all necessary cables (network, telephone lines, power) to the installed modules. Ensure proper cable routing to avoid obstruction of airflow.
6. Close the front access panels.

5. Operating Considerations

The cabinet itself is a passive housing unit. Its 'operation' is defined by the proper functioning of the telecommunication components installed within it. Once all modules are correctly installed and powered, the system will begin operation according to its configuration.

• Power On: After all components are installed and connected, apply power to the system. Refer to the specific manuals for the CPU and power supply for their power-up sequences.
• System Capacity: The DSX 160 system, when housed in this cabinet, supports a maximum of 96 actual stations (digital and analog). With two T1/PRI cards, total portage can reach 144, and with IntraMail, up to 152 ports. The remaining 8 ports can be used for doorboxes or unassigned voice mailboxes.
• Monitoring: Regularly check the status indicators on the installed CPU and other modules to ensure proper operation.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of the equipment housed within the cabinet.

• Cleaning: Periodically clean the exterior of the cabinet with a soft, dry cloth. Do not use liquid cleaners directly on the cabinet or near ventilation openings.
• Ventilation: Ensure that the ventilation holes on the cabinet are free from dust and obstructions. Dust accumulation can lead to overheating of internal components.
• Cable Management: Periodically inspect internal and external cabling for any signs of wear, damage, or loose connections. Re-route cables if they obstruct airflow or access.
• Component Check: During scheduled maintenance, verify that all installed modules are securely seated in their slots.

7. Troubleshooting

This section addresses common issues related to the cabinet itself. For issues related to the functionality of the telecommunication system, refer to the manuals for the specific CPU and modules installed.

• Overheating: If components inside the cabinet are overheating, ensure all ventilation openings are clear. Verify that the ambient temperature of the installation environment is within acceptable limits.
• Loose Components: If a module is not functioning, ensure it is fully seated in its slot. Power down the system before re-seating any cards.
• Physical Damage: If the cabinet sustains physical damage, assess if it compromises the protection of internal components. Replace the cabinet if structural integrity is compromised.
