No connectivity

Incorrect or bad cable

These are results of no link at both 
ends:

•

A crossover cable was used 
when a straight-through was 
required, or vice-versa.

•

The cable is wired incorrectly.

•

A crossover or straight-through 
cable is wired incorrectly.

•

STP checking for possible 
loops.

•

For the correct pinouts and 
the proper application of 
crossover vs. 
straight-through cables, see 
the 

“Two Twisted-Pair 

Cable Pinouts” section on 
page B-5

.

•

Enable the automatic 
medium-dependent-
interface crossover 
(Auto-MDIX) feature.

Note

Many legacy powered 
devices, including older 
Cisco IP phones and 
access points that do not 
fully support IEEE 
802.3af, might not 
support PoE when 
connected to the 
switches by a crossover 
cable.

•

Replace with a tested good 
cable.

•

For 1000BASE-T 
connections, be sure to use 
a twisted four-pair, 
Category 5 cable.

•

Wait 30 seconds for the port 
LED to turn green.
