Note The Catalyst 3750 switch can connect to a Cisco IP Phone through a
straight-through, twisted four-pair Category 5 cable. The rear panel of the
Cisco IP Phone might have more than one RJ-45 connector. Use the
LAN-to-phone connector to connect the IP phone to the switch. Refer to
the Cisco IP Phone documentation for more information about connecting
devices to it.
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.
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 the switch and the connected device have
established link.
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 Chapter 4, “Troubleshooting,” for
solutions to cabling problems.
Step 3 Reconfigure and reboot the connected device if necessary.
Step 4 Repeat Steps 1 through 3 to connect each device.
