10/100 And 10/100/1000 Poe+ Port Connections - Cisco 2960-S Hardware Installation Manual

10/100 and 10/100/1000 PoE+ Port Connections

Figure 2-25
1
Connect the other end of the cable to an RJ-45 connector on the other device.
Step 2
Observe the port status LED.
Step 3
The LED turns green when the switch and the other device have an established link.
The LED turns amber while the STP discovers the network 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. See
cabling problems.
If necessary, reconfigure and restart the switch or other device.
Step 4

10/100 and 10/100/1000 PoE+ Port Connections

See the
for information on the cables and connectors.
The ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco
prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power when an
IP phone or an access point is connected.
To access an advanced PoE planning tool, use the Cisco Power Calculator available on Cisco.com at this
URL:

You can use this application to calculate the power supply requirements for a specific PoE configuration.
The results show output current, output power, and system heat dissipation.
