Front Panel
PoE-Capable Downlink Ports (Catalyst 2960CPD-8PT-L, 3560CG-8PC-S, 3560CPD-8PT-S,
2960C-8PC-L, 2960C-12PC-L, 3560C-8PC-S, and 3560C-12PC-S)
Depending upon the available PoE budget, these switches can power other PoE-capable devices such as
IP phones, access points, and so on. See
Table 1-2
for PoE budgeting information. See
Figure 1-6
.
For information on powering the switches, see the
“Powering the Switch” section on page 2-4
.
USB Type A Port
Some models have an USB Type A port. This port provides access to external Cisco USB flash devices
(also known as thumb drives or USB keys). The port supports Cisco USB flash drives with capacities
from 64 MB to 1 GB.
Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy,
as well as the capability to format the flash device with a FAT file system.
For more information about the switch management ports, see the switch software configuration guide
and the command reference on Cisco.com.
Dual-Purpose Ports
You can configure the dual-purpose ports on the switch as either 10/100/1000 ports or as SFP-module
ports. You can set the 10/100/1000 ports to autonegotiate, or you can configure them as fixed 10, 100,
or 1000 Mb/s (Gigabit) Ethernet ports.
By default, the switch selects the medium for each dual-purpose port (10/100/1000BASE-T or SFP).
When a link is achieved on one media type, the switch disables the other media type until the active link
goes down. If links are active on both media, the SFP-module port has priority, but you can use the
media-type
interface configuration command to manually designate the port as an RJ-45 port or an SFP
port.
You can configure the speed and duplex settings consistent with the selected media type. For information
on configuring interfaces, see the switch software configuration guide.
SFP Modules
The switch Ethernet SFP modules provide connections to other devices. These field-replaceable
transceiver modules provide the uplink interfaces.The modules have LC connectors for fiber-optic
connections or RJ-45 connectors for copper connections.
You can use any combination of these supported SFP modules:
