Chapter 2 Switch Installation
Follow these steps to connect to 10BASE-T, 100BASE-TX, or 1000-BASE-T devices:

medium-dependent interface crossover (auto-MDIX) feature. The switch then detects the required cable
type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use
either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or
1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the
connection.
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for
loops. This takes about 30 seconds, and then the port LED turns green. If the port LED does not turn on,
the device at the other end might not be turned on, or there might be a cable problem or a problem with
the adapter installed in the attached device. See

On user network interface (UNI) ports, the port LED is green after the link is established. It does
not turn amber because STP is not supported.
