Giganet 2U Closed Cable Manager — 19-Inch Rack Mount (GN-290010)
The Giganet 2U Closed Cable Manager (GN-290010) is a horizontal rack accessory designed to organise, route, and protect patch cords in standard 19-inch network racks and data cabinets. Its defining feature is a solid removable front cover that conceals cables behind a clean panel face — distinguishing it from open-style cable managers where cable bundles remain visible. This closed design is suited to equipment rooms, server rooms, and IT closets where rack presentation, dust protection, and cable security are priorities alongside functional cable organisation.
At 2U, the Giganet 2U Closed Cable Manager provides double the internal routing space of the 1U equivalent. This additional depth accommodates higher cable counts and larger cable gauge bundles — particularly relevant in high-density patch environments where multiple Cat 6A or fibre patch cords enter and exit from a single rack position.
Closed Front Cover Design
The front cover of the Giganet 2U Closed Cable Manager is a removable snap-on panel that encloses the cable routing space. This construction provides three practical benefits over open cable managers:
Cable concealment — Patch cords routed through the manager are hidden behind the front panel, giving the rack a uniform, professional appearance. In customer-facing equipment rooms and shared data centres, this appearance is an operational requirement as much as an aesthetic choice.
Dust and contamination protection — The closed cover reduces dust accumulation on patch cord connectors and keystone jack ports within the cable management space. Dust ingress on optical fibre connections in particular is a known cause of signal degradation that requires cleaning intervention.
Tamper and accidental disconnection prevention — Enclosed patch cords are less accessible to accidental contact during adjacent equipment maintenance. This reduces the incidence of unintentional cable pulls that cause unplanned network outages in active racks.
The snap-on attachment mechanism allows the cover to be removed quickly during patching operations and refitted without tools, maintaining the closed appearance after each maintenance activity.
Finger Duct Construction
The internal routing space of the Giganet 2U Closed Cable Manager is equipped with high-density slotted finger ducts. These vertically oriented fingers guide cables into and out of the manager while maintaining the minimum bend radius required for both copper and fibre patch leads.
Bend radius compliance is a critical functional requirement — not a passive feature. Cat 6 patch cords require a minimum bend radius of approximately 25mm; Cat 6A patch cords require 32mm. Fibre patch leads have even more restrictive bend radius requirements depending on fibre type and connector. Violating bend radius limits at the cable management point permanently degrades cable performance at that location, introducing insertion loss on fibre and NEXT degradation on copper — faults that are difficult to locate after installation is complete.
The 2U finger duct depth provides increased horizontal routing capacity compared to 1U models, allowing larger cable bundles to enter and exit from both sides of the manager without stacking cables vertically beyond the duct height. Additionally, rear pass-through apertures allow cables to be routed from the front patching face through to the rear of the rack for connections to rear-mounted equipment or vertical cable management pathways.
Capacity and Cable Management
The Giganet 2U Closed Cable Manager supports up to 200 patch cords depending on cable gauge. This capacity reflects the 2U internal volume and finger duct density — approximately double the cable count of the 1U GN-290009 model. In practice, usable capacity varies with cable mix: Cat 6A patch cords at 7.5–8mm outer diameter occupy more space per cord than Cat 6 cords at 5–6mm, and mixed copper and fibre deployments require routing discipline to maintain bend radius compliance for both cable types simultaneously.
The cable manager accommodates both left-exit and right-exit routing, allowing patch cords from centrally positioned patch panels to be directed towards vertical cable management channels on either side of the rack without crossing over one another. This bidirectional routing reduces cable crossing and tangling in high-density rack configurations.
Rack Compatibility and Installation
The Giganet 2U Closed Cable Manager is built to the 19-inch rack standard, with a panel width of 482.6mm and a 2U height of 88.9mm (3.5 inches). It is compatible with all standard EIA-310 19-inch two-post and four-post racks, open frame racks, and enclosed network cabinets. Pre-drilled mounting holes accept standard M6 cage nuts and rack screws for straightforward installation without modification.
The unit is finished in black to match standard 19-inch patch panels, switches, and rack equipment from Giganet and third-party manufacturers. This colour consistency maintains a uniform rack appearance across mixed-brand installations.
Construction is available in metal (cold-rolled steel) or high-impact ABS plastic variants depending on SKU. Metal variants carry a load capacity of up to 15kg, suitable for loaded cable bundles on high-density patch positions. The unit weighs approximately 2.5kg in metallic form factor.
Airflow and Thermal Management
Cable managers in rack environments directly affect airflow. Poorly routed cable bundles that spill across rack unit positions obstruct the front-to-back airflow path through active equipment — increasing inlet temperatures and potentially triggering thermal throttling or shutdown in switches and servers in the same rack.
The Giganet 2U Closed Cable Manager channels cables horizontally within its enclosed space rather than allowing them to hang freely across adjacent rack units. Combined with the closed front cover, this construction keeps cables contained within the designated 2U position and away from the airflow inlets of adjacent active equipment. Consequently, the cable manager contributes to consistent thermal management across the full rack height when deployed between patch panels and active switching equipment.
Supported Applications
The Giganet 2U Closed Cable Manager is suited to the following rack cabling environments:
- High-density patch panel installations — Cat 5e, Cat 6, and Cat 6A copper patch cord management between patch panels and access switches
- Fibre distribution frames — LC, SC, and MPO fibre patch lead routing with bend radius control
- Data centre top-of-rack and end-of-row configurations — Cable organisation between ToR switches and server patch panels
- Network cabinet builds in IT closets and comms rooms — Structured cabling termination environments requiring tidy, maintainable rack layouts
- Mixed copper and fibre racks — Simultaneous routing of copper and optical patch leads with appropriate bend radius separation
Ideal Users
- Structured Cabling Contractors and Rack Builders — The closed front cover delivers the clean rack finish required on project handover documentation and customer acceptance inspections. The 2U depth and 200-cable capacity accommodates high-density patch panel positions without requiring multiple cable managers per panel — reducing rack unit consumption on cable management hardware.
- Data Centre Operators and Colocation Facilities — In co-lo environments where multiple tenants occupy the same rack or adjacent rows, closed cable management prevents cable interaction between adjacent rack positions during maintenance. The dust protection benefit is particularly relevant for fibre patch lead connectors in environments where racks are accessed frequently by multiple parties.
- IT Infrastructure Managers in Corporate Environments — Equipment rooms in office buildings are accessed by a range of personnel beyond dedicated network engineers. Closed cable management reduces the risk of accidental cable pulls during server, UPS, or PDU maintenance work performed by non-network staff in the same rack.
- Network Installers on Education and Healthcare Projects — Rack installations in education and healthcare facilities are subject to regular access by non-technical facilities staff for equipment power cycling and peripheral connections. The closed design protects the structured cabling layer from inadvertent interference during these routine activities.
- Systems Integrators Specifying Complete Rack Solutions — As part of a complete rack build alongside Giganet patch panels, cable managers, and blanking panels, the GN-290010 maintains aesthetic and functional consistency across the installation. Single-vendor rack component sourcing simplifies procurement, reduces colour and finish variation, and supports a unified warranty approach.
