Cleaned inside the cabinet, never touching a link.
Patch cabinets are packed. Dense copper and fibre, active switches, and dust settling on every panel and connector. We clean the interior, panels and cable management around it all, HEPA 14 and ESD-safe, without touching a connector or disturbing a live link.
The tightest, dustiest space in the room
A patch cabinet is where the network’s density peaks. Hundreds of copper and fibre connections, often mixed with active switches, in a closed box that rarely gets opened. Dust does not just settle there; it clings to connectors and panels, blankets the active gear and blocks its ventilation, and works into the airflow every time the cabinet is opened. Cleaning it is not like wiping down a rack. It is precise, careful work in a confined space full of live links.
Why clean a cabinet from the inside
Dust in a patch cabinet hits exactly the things you cannot see: connections, cooling and the reliability of your network.
Connection integrity
Dust on and around connectors, especially fibre, degrades signals, and the cabinet is exactly where it accumulates. We clear it from around every link.
Airflow & cooling
Active switches in the cabinet need to breathe. Dust blankets them, traps heat and shortens their life. We clear the vents and airflow paths.
Static (ESD)
A dense connection space is an ESD risk. All our staff are ESD-trained and work with antistatic materials.
Never disturbed
In a cabinet this packed, one careless move is an outage. Our method never touches a connector or moves a live link.
Confined, dense, live
Cleaned around every connection
A patch cabinet is the hardest place in the room to clean. Confined, dense, and full of live connections. The whole method is built around one rule: never touch a connector or disturb a link. HEPA 14 extraction pulls dust out of the tight space instead of stirring it over the connectors and active gear. Everything is ESD-safe. And because these cabinets carry a facility’s network, our staff are security-screened and work under confidentiality.
- Never touches a connector
- HEPA 14 in the tight space
- ESD-safe
- Security-screened & confidential
What we clean
Everything inside the cabinet, around the connections, never at the connectors.
- Cabinet interior surfaces & floor
- Patch panels & frame, around the connectors
- Cable management, ducts & trays inside
- Active equipment surfaces & vents
- Doors, filters & fans
- Dust extracted with HEPA 14, not stirred
We clean around the connections. Cleaning connectors and optical fibre end-faces is network work and is not part of this service.
How we work
A controlled, repeatable process, built around leaving every connection exactly as it was.
- 01
Survey & map
We map the cabinet’s density, its active gear, the fragile fibre, and the access.
- 02
Plan & coordinate
Which cabinets, how and when, agreed with your team in advance, around the network.
- 03
Careful cleaning
HEPA 14 extraction in the confined space, ESD-safe, around every connector, without disturbing a link.
- 04
Check & close
Clean, every connection untouched, airflow restored, checked and documented.
The standards we work to
Cleaning in the densest, most sensitive space in your network calls for controlled standards.
ESD-safe working
Antistatic materials and ESD-trained staff prevent the static discharges that damage connectors, optics and network electronics.
HEPA 14 filtration
Our extraction captures ≥99.995% of fine particles, so dust leaves the cabinet instead of being stirred over the connectors and switches.
ISO 14644-1 Class 8
The air-cleanliness benchmark for data halls. Where required, we clean cabinets to the same standard as the room around them.
Frequently asked questions
Do you touch the connectors or fibre?
No. We clean the cabinet interior around them. Cleaning connectors or optical fibre end-faces is network-engineering work, not something we do.
Do you disconnect or reseat anything?
No. We work strictly hands-off the live links, cleaning around them.
What about active switches in the cabinet?
We clean their surfaces, vents and the cabinet’s airflow paths so they do not overheat. Around the connections, never through them.
Is this the same as MER/SER room cleaning?
MER/SER room cleaning is the room around the cabinets; this is the inside of the cabinets. They are often done together. See MER/SER room cleaning.
How often should patch cabinets be cleaned?
It depends on the environment and how often they are opened; we set it from a survey. Because they are closed and dense, dust builds up unseen.
