Checking Hub Connections

When you have connected your hubs, power on the
hubs and your switch. The Port Status LEDs for the
ports you have used on both the hubs and the
switch should be green. If they are not, check your
connections and the settings of the MDI/MDIX
switches.

Spot Checks

At frequent intervals, visually check that:
The Alert LED is off — this is the best way to
ensure there are no problems with your network
Case vents are not obstructed
Cabling is secure and not pulled taut
If you suspect a problem, refer to
