Network Switch Repair in Nairobi, Kenya
A failed switch can take down a floor, a site or a camera network. Sinsal repairs switches at the board level, so a unit that no longer powers on or no longer links can often be returned to service instead of replaced.
Equipment Covered
- Managed and unmanaged Ethernet switches
- PoE and PoE+ switches
- Access and aggregation switches
- Industrial and DIN-rail switches
- SFP and fibre-uplink switches

- Switch does not power on or restarts repeatedly
- PoE ports no longer power connected devices
- Ports that do not link or drop traffic
- Damage from lightning or mains surges
- Overheating from blocked ventilation or failed fans
- Boot loops after interrupted firmware updates
Diagnostic Process
- 01Record of the model, symptoms and any surge or power event
- 02Visual and microscope inspection for burnt or corroded areas
- 03Bench power-up with rail analysis on main and PoE stages
- 04Oscilloscope and thermal checks on regulators and port stages
- 05Hardware versus firmware determination
Repair Process
- 01Replacement of failed regulators, protection devices and PoE components
- 02Repair of damaged traces, pads and port connectors
- 03Firmware recovery where corruption is the cause
Testing and Validation

Frequently Asked Questions
Common Questions
Can a switch that will not power on be repaired?
Often. The fault is frequently in the power input or a regulator. Assessment confirms the failed part and whether it can be replaced.
Do you repair PoE switches?
Yes, at the board level, subject to assessment of the model and fault.
Can you repair switches that will not boot after a firmware update?
Frequently, through hardware-level firmware recovery, confirmed at assessment.
Have Failed Network Switches?
Describe the equipment and the fault. Sinsal will confirm whether it is a fit for diagnostics and repair before any work begins.
