Checking Unit Connections

When you have connected all your units, power on the units and the Switch. The Port Status LEDs for the ports you have used on both the units and the Switch should be on. If they are not, check your connections.

OfficeConnect

Hub

Twisted pair cable with RJ-45 connectors.

Maximum length is

100m (328ft)

There is no uplink/normal push switch that is usually associated with OfficeConnect products. Instead the product has an automatic MDI / MDIX (Media Dependant Interface)

feature, it means either a 'straight through' or 'crossover' UTP cable can be used in any Switch port to make the connection to other switches, hubs and workstations. The switch will automatically detect which wiring practice has been followed and will compensate accordingly.

Spot Checks

At frequent intervals, visually check that:

The Alert LED is off — this is the best way to find out if there are problems with your network.

Case vents are not obstructed.

Cabling is secure and not pulled taut.
