1. Racking, Stacking & Mounting Services

Executing precise physical deployments within active server cabinets requires heavy-duty payload management and strict adherence to structural safety guidelines.

Hardware Enclosure Mounting

Ensuring structurally sound device loading and uniform thermal environments inside high-density layouts:

  • Weight Distribution: Planning heavy devices low in the cabinet to avoid uneven loads.
  • Rail & Cage-Nut Mounting: Secure installation of devices in universal 19-inch rails using cage nuts.
  • Grounding Connection: Connecting device chassis to the existing facility grounding point as instructed. Electrical inspection of the facility itself is not part of this service.

3. High-Density Structured Cabling & Patching

Eliminating performance issues by preventing cable congestion and enforcing strict macro-bend management across thousands of interconnect paths.

Consistent port labelling, controlled bend radius, and end-to-end verification reduce patching faults.

Structured Patching Architecture

Deploying permanent, high-performance physical cable loops using industry-recognized tools:

  • Fiber Installation: Precision installation of single-mode (OS2) and multi-mode (OM3/OM4) fiber systems utilizing MPO multi-fiber trunk cables.
  • Copper Patching: Neat, systematic patching of Cat.6A shielded (STP) cabling.
  • Permanent Labeling: Industrial thermal tag printing that matches your logical wire maps for fast troubleshooting.

Test Equipment

Every deployment is verified on-site using premium test instrumentation to document that each link meets the agreed requirements:

  • Fluke SimpliFiber Pro: Used for optical power loss verification across 850nm/1300nm multi-mode and 1310nm/1550nm single-mode networks.
  • Fluke LinkIQ: Verifies frequency response up to 10G speeds and checks Power-over-Ethernet (PoE) performance under active load.
  • Visual Fault Location (VFL): High-visibility light injection to quickly trace fiber micro-bends and localized line leakage.

4. Hardware Swaps & "Lift-and-Shift" Migrations

Executing emergency maintenance and planned hardware lifecycle replacements with careful tracking to minimize the risk of data loss.

Precision Migration Protocols

Systematic de-racking and deployment management for sensitive enterprise storage data clusters and routing components:

  • Hot-Swap Interventions: Replacing failed redundant power supply units (PSUs), hot-plug system fans, and line cards on production hardware without disrupting live traffic.
  • Cabinet Lift-and-Shift: Comprehensive mapping, labeling, removal, secure transport, and destination deployment of active storage clusters.
  • Out-of-Band Validation: Connecting direct physical FTDI USB-C/RJ45 lines to terminal lines to monitor remote boot loops alongside your NOC engineers.

5. Fiber Handling & Connector Care

Most optical faults come from dirty or damaged connectors rather than the cable itself, so every mating follows the same short routine.

Connector care routineFour steps: inspect, clean, re-inspect and mate. If the connector is still dirty after cleaning, the clean step is repeated.1Inspect2Clean3Re-inspect4MateStill dirty? Repeat
Every fiber connection follows the same four steps. Dust caps stay on until the moment of connection.

Inspect, Clean, Re-Inspect

Connector end-faces are checked before every mating and again after cleaning.

  • Dust caps stay on until the moment of connection and go back on after disconnection.
  • Dry or wet cleaning is chosen to match the contamination found.
  • End-face quality is assessed against IEC 61300-3-35 criteria where the project requires it.

Routing & Bend Radius

Fiber is protected from the pressure and tight bends that cause hidden loss.

  • Fiber runs in dedicated pathways, separate from copper bundles and power cabling.
  • Cables stay above the manufacturer's minimum bend radius, including at cabinet doors and vertical managers.
  • Hook-and-loop straps are used instead of tight cable ties to avoid micro-bends.

MPO Trunks & Polarity

Multi-fiber links fail quietly when gender or polarity is wrong.

  • Pinned and unpinned MPO connectors are checked before mating.
  • End-to-end polarity (Type A, B or C method) is verified against the transceiver type, for example SR4 parallel optics.
  • Trunk and cassette orientation is recorded in the wire map.

6. Typical Task Scenarios (Step by Step)

How common assignments are carried out, always under the direction of your remote NOC or project lead.

Like-for-like switch replacementSix steps: photograph and record the port map, label both cable ends, power down after NOC approval, swap the unit, re-cable according to the port map, and check the boot sequence with the NOC.1Photo andport map2Label bothcable ends3Power downafter NOC OK4De-rack old,mount new5Re-cableper port map6Boot checkwith NOC
Switch replacement follows the same sequence every time, under the direction of your remote NOC.

Like-for-Like Switch Replacement

  1. Photograph the cabling and record the port-to-cable mapping before disconnecting anything.
  2. Label every cable at both ends where labels are missing.
  3. Power down and de-rack the old unit once your NOC confirms.
  4. Mount the replacement and restore every cable strictly according to the port map.
  5. Power on, connect the console and watch the boot sequence together with your NOC.
  6. Photograph the final state and report the serial numbers of both units.

New Cabinet Turn-Up

  1. Verify cabinet position, grounding connection and both power feeds (A/B).
  2. Install rails, cage nuts and devices according to the rack elevation plan.
  3. Connect power with A/B separation and check the load distribution.
  4. Patch copper and fiber according to the connectivity matrix and label both ends.
  5. Test the links and export the reports.
  6. Hand over the layout map and the serial allocation list.

Fiber Trunk Installation & Test

  1. Inspect and clean all connectors before and after installation.
  2. Route the trunks through the designated pathway at the correct bend radius.
  3. Verify MPO polarity and fiber mapping from end to end.
  4. Measure optical power loss at the required wavelengths.
  5. Compare results with the agreed loss budget, then re-clean and retest any failures.
  6. Export the results as .flw files or PDF reports via LinkWare.

Decommissioning & Lift-and-Shift

  1. Confirm the asset list and the shutdown approval from your NOC before touching any hardware.
  2. Map and label all power and data connections.
  3. De-rack, tag and pack the equipment, recording serial numbers.
  4. Rebuild at the destination according to the new layout plan.
  5. Verify connectivity and power redundancy, then hand over the updated documentation.

7. Site Safety & Working Practices

Working in live environments means protecting both people and equipment.

Each device draws from both feeds, A and B, and the cabinet frame is bonded to the grounding system.

ESD Protection

Wrist straps and grounded work surfaces are used when handling line cards, modules and drives.

Change Discipline

Only the equipment named in the ticket is touched. Every step that could affect live traffic is confirmed by your remote team before it is carried out.

Safe Handling

Heavy chassis are moved with suitable lifting equipment or a second person, and cabinet load limits are respected.

Clean Work Areas

Packaging stays out of the white space, tools are counted in and out, and floor tiles and cable trays are left as they were found.
