The N68-22 Cabinet Installation Guide describes the installation, usage, and maintenance features of the N68E-22 cabinet. This document is intended for installation personnel and provides comprehensive information on setting up the cabinet, its accessories, and associated cabling.
Function Description
The N68E-22 cabinet is designed with a modular structure, offering ample space for installing various devices, such as subracks. This modularity facilitates both capacity expansion and maintenance activities. The cabinet's load-bearing components include the front and rear columns of the racks, middle columns, and door frames, ensuring structural integrity. Other parts, such as mounting bars, front and rear doors, wooden plates on both sides, front and rear wire bushings, and guide rails, are not load-bearing but contribute to the overall functionality and organization of the cabinet.
The N68E-22 cabinets are available in two configurations: single-door and double-door. The BSC6910 series cabinets exclusively support the double-door mode, while the BSC6900 series cabinets are compatible with both single-door and double-door modes, providing flexibility based on specific deployment requirements. The cabinet's surface color is purple and gray, giving it a distinct appearance.
The installation process involves several key steps:
- Unpacking and Inspection: Before installation, cases are unpacked, and items are checked against the packing list. This includes verifying the number of cases, checking shockwatch labels for signs of impact during transportation, and inspecting cases for any damage or soaking.
- Cabinet Installation: The cabinet can be installed on either a concrete floor or an ESD floor.
- Concrete Floor Installation: This involves positioning and securing the N68E-22 cabinet directly onto a concrete surface.
- ESD Floor Installation: For ESD floors, the N6X series support assembly is used to install the cabinet, ensuring proper grounding and static discharge.
- Accessory Installation: This includes installing the front and rear doors, as well as the side panels.
- Cabling: External power cables and PGND (Protective Grounding) cables are installed. PGND cables are also installed for the doors and side panels to ensure proper grounding.
- Labeling: Engineering labels, including row and column labels, are attached to the cabinets and cables for identification and organization.

- Product Compatibility: The cabinet is compatible with eCoordinator, BSC6910, and BSC6900 products, indicating its role in supporting specific network infrastructure.
- Safety Considerations: The manual emphasizes safety precautions during unpacking and installation, such as handling equipment carefully to avoid collisions and wearing ESD wrist straps or gloves when handling electronic components to prevent static damage.
Maintenance Features
The N68E-22 cabinet incorporates features that simplify maintenance and ensure the longevity of the equipment:
- Accessibility: The design, including front and rear doors and side panels, allows for easy access to internal components for maintenance and servicing. The installation guide details how to install these accessories, implying they can also be removed for access.
- Grounding System: The installation of PGND cables for doors and side panels ensures a robust grounding system, which is vital for electrical safety and protection against electromagnetic interference, contributing to equipment reliability and reduced maintenance needs related to electrical issues.
- Inspection and Verification: The unpacking and installation procedures include detailed checks for damage, missing items, and proper installation. This proactive approach helps identify and address potential issues early, reducing the likelihood of future maintenance problems.
- Documentation: The "Cabinet Installation Record" and "Checklist for the Cabinet Installation" sections provide structured methods for recording installation information and verifying completion, which are invaluable for future maintenance and auditing.
- ESD Protection: Guidelines for handling electronic components, such as wearing ESD wrist straps and proper storage in ESD bags, are critical for preventing damage from static electricity, a common cause of equipment failure and subsequent maintenance.
- Environmental Protection: Instructions for storing unpacked equipment indoors for proper storage and taking photos of storage environments, rusted/corroded equipment, and packing materials highlight the importance of protecting equipment from environmental factors that could lead to damage and increased maintenance.
- Troubleshooting Support: The guide outlines steps to take if issues arise during unpacking, such as contacting Huawei support for cargo problems or damaged items, ensuring that professional assistance is available for resolving complex issues.
