Connecting The Switch To Compatible Devices; Connecting To 10Base-T Or 100Base-Tx Devices - Cisco WS-C3560-48PS-S Hardware Installation Manual

Connecting the Switch to Compatible Devices

The Catalyst 3560 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. See the Cisco IP Phone
documentation for more information about connecting devices.
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.

Connecting to 10BASE-T or 100BASE-TX Devices

When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through
Step 1
cable to an RJ-45 connector on the front panel. (See
repeaters, use a crossover cable. (See the
cable-pinout descriptions.)
Figure 2-18
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
Step 2
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
problems.
