Reliance on Ethernet

According to Andrew Lane, European marketing manager at Ideal Industries Networks, organisations that rely heavily on Ethernet need to be able to troubleshoot quickly and effectively to avoid downtime.

“Any user of Ethernet has to accept that there will inevitably be network problems from time to time; devices can’t always connect to other devices, there can be IP (Internet Protocol) address conflicts, servers can go down and of course, the network can run slowly,” he says.

“Critically, there are always going to be cabling problems.  In fact around 70-80 per cent of network issues relate to cabling.  For example, two very common problems in an office environment which can affect data transmission are a) damaged cables – often caused by mice chewing through them – and b) disorganised and untidy patch panels.”

Lane admits that Ethernet and cabling problems are almost impossible to avoid sometimes, but as a way to ensure that the effects of downtime are kept to a minimum, he suggests investing in a purpose-built troubleshooting tool.

“Since we know that network issues will invariably occur, and they need to be rectified as soon as possible, it makes sound commercial sense to invest in a purpose-designed troubleshooting tool,” he explains.
