Has anyone seen my desk?

You are installing a new gigabit Ethernet connection, and when you plug in the network cable into your laptop the status light indicators are dark. Which of these would be the most likely status of the network connection?

A) The DHCP server has not assigned an IP address

B) There is no signal on the Ethernet cable

C) The Ethernet link is running at 100 megabits per second instead of 1 gigabit per second

D) The primary DNS server is not responding

E) You shouldn’t wear your sunglasses inside of the building

The answer: B) There is no signal on the Ethernet cable

Status light indicators on Ethernet ports will generally light when any connection is made to another device, and another light will blink when traffic is seen on the wire. If there are no lights, then there’s usually a cabling problem between the workstation and the network switch on the other end.
