What a Service Visit Covers
Finding the Real Fault
A slow network, a camera that keeps dropping or a dead wall jack often traces back to something small: a bad patch cord, a failed switch port, a damaged cable run or a dirty fiber connector. Our technician tests before replacing anything, so parts get swapped only when the testing points to them. Our guide on testing Ethernet cabling explains what we look for.
Fiber and Copper Repairs
Cut, crushed or damaged fiber is repaired with fusion splicing, done in-house, and every repaired strand is loss tested before we leave. Copper runs that fail are re-terminated or replaced, then certification tested. Read more about fiber optic installation and repair and how fiber loss testing works.
Network Equipment
Switches, firewalls and access points fail or fall out of date. We replace failed hardware, set it up again or restore a saved configuration when one is available, and confirm that registers, cameras and guest WiFi are still on separate networks. Since cameras, audio and signage all ride on the same network, fixing the network often fixes them too. More on business networking and WiFi.
Systems We Did Not Install
Some sites have no record of which cable goes where. We work on systems other contractors installed. As we trace a problem, we label the runs and ports we touch and add them to the notes you get at close-out, so the next visit starts from a record. See how to document network ports.
Common Questions
What should a service request include? The site address, what stopped working and when it started, and anything that changed recently. Photos of the rack or the problem area help, and you can email them to info@chaincomm.com.
Can you work from our ticketing system? Yes. We can take calls through your work-order system and add our notes to the ticket.
Where do you take service calls? Maryland, Virginia, Washington, DC, Delaware, Pennsylvania and New Jersey. See our Mid-Atlantic service area.
