Work Instruction for Installation of Cable Management System For
Cable Management System (CMS) Outline The CMS system proposed consists of a fully integrated inter-suite Fibre and Copper cable management and routing system mounted on a Rapid Access Cable System Support (RACSS) frame structure. RACSS The RACSS frame consists of a series of horizontal & vertical frames with brackets which come in modules L1 to L5 to suit the number of 600mm wide cabinets to be served. The main spine fibre raceway is supported on the RACSS frame on each suite line and facilitates 2 drops to the front left and right of the cabinet to direct fibre into designated channels within the cabinet. Copper cable both Cat5 and DC inter-suite cable runs are all contained in basket again mounted on the RACSS frame, but on a different level. The RACSS system was designed for rapid deployment of CMS systems for both fibre and copper cable, was initially designed for working at height restrictions of 3meters with the further integration of cabinet support and also facilitates a completely integrated earth bonding system to each cabinet. Fibre Management The system proposed fully complies with fibre deployment management criteria of (1) Containment, (2) Access, (3) Routing and (4) Bend Radius Control. Telecom`s equipment today are operating at Giga bit rates and by superior fibre management the equipment and network circuits will operated at a very efficient rate, without incurring expensive losses for the network operator. Fibre Equipment Cabinet The Cabinet proposed was designed to support superior optical fibre patchcord management with specific channels built into the cabinet in particular within the 600 wide footprint and is an integral part of the RACSS frame installation The equipment proposed has front exiting fibre which is horizontally and vertically managed to the side fibre channels i n the cabinet, with specific brackets employed to comply with 35mm bend radius control criteria for patchcord fibres.
Scope of Work. The purpose of the installation is to provide a reliable and secure cable management system for optical fibre connectivity, copper cables, Cat5 and DC power feeds. It is envisaged that possibly up to ten Optical Equipment cabinets 600wx1000dx2200h will eventually occupy this area. The rapid access cable support system (RACSS) is normally a stand alone arrangement, supported by it’s own vertical frame bracing, but in this instance because of restrictions, the RACSS Frame will be supported from the cabinets. The cabinet roofs are specially constructed with reinforced support bars to allow for this. Also, the initial quantity of cabinets will be strategically positioned to support the RACSS & cable Management System (CMS). The cabinets will be secured to the false floor. The intention is to install the RACSS system to cover two suite lines. These two suites will both have a fibre raceway (6”x6”) and a steel basket (220mmx110mm) for copper cables and the two lines will be joined at one end to provide for continuous inter-suite cable access between suite lines. The fibre drops to the cabinets will come off express exits and be routed through 50x50mm drops so as to allow the fibre drop nicely into the specially constructed entries of the cabinets. 2 drops initially to be installed day 1 with option to 2 more drops to rear of cabinet at a later date. An earth window will be fixed at a convenient location on the RACSS to facilitate earth bonding to each cabinet. Refer to cabinet specification for specific features proposed.
General Safety Notes:
Summary The integrated Cable Management System proposed comprises of state of the art and proven fibre and copper cable management procedures and practices currently employed in Next Generation Network (NGN) platforms.
