Switch Installation
Procedure
Step 1
Connect one end of the cable to the switch PoE port.
Step 2
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when
both devices have established link.
The port LED is amber while STP discovers the topology and searches for loops. This process takes about
30 seconds, and then the port LED turns green. If the LED is off, the other device might not be turned on,
there might be a cable problem, or there might be a problem with the adapter in the other device.
Step 3
Reconfigure and reboot the connected device, if needed.
Step 4
Repeat Steps 1 through 3 to connect each device.
Note
10/100/1000 Port Connections
The switch 10/100/1000 port configuration changes to operate at the speed of the attached device. If the
attached ports do not support autonegotiation, you can manually set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can
reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the interface speed and duplex parameters on both ends of the connection.
Auto-MDIX Connections
The autonegotiation and the auto-MDIX features are enabled by default on the switch.
With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If
the attached device does not support autonegotiation, you can manually set the switch interface speed and
duplex parameters.
With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures
the interface accordingly.
If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.

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.
