Cisco Systems 3560-C manual USB Type A Port, Dual-Purpose Ports, SFP Modules

Chapter 1 Product Overview

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 1-2for 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-typeinterface 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:

•GLC-LH-SM=

•GLC-SX-MM=

•GLC-ZX-SM=

•GLC-BX-D=

•GLC-BX-U=

•GLC-FE-100FX=

•GLC-FE-100LX=

•GLC-FE-100BX-D=
