PoE Ports

The ports provide PoE support for devices compliant with IEEE 802.3af and IEEE 802.3at and also provide PoE support for Cisco IP Phones and Cisco Aironet Access Points. The PoE switch ports are Power Source equipment (PSE) capable and source power to PD devices connected to the downlink ports. A switch can source POE power of up to 30W per port.

Depending on the switch model and the number of PoE ports, the maximum switch power output varies. For the 24-port switch models, the power range is between 195W to 370W. For the 48-port switch models, the power range is between 180W and 740W. 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.

The PoE ports use RJ-45 connectors with Ethernet pinouts. The 10BASE-T, 100BASE-TX, 1000BASE-T traffic requires Category 5 or Category 5e twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.

10/100/1000 Ports

The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The 10BASE-T, 100BASE-TX, 1000BASE-T traffic requires Category 5 or Category 5e twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or 
Category 4 UTP cable.

When medium dependent interface (MDI) on peer devices do not have the Automatic Polarity Correction feature, the C1000-24T-4G-L switch model requires ports 2,4,12 and 20 to be connected with a cross-over cable, and ports 7,14,15 and 23 to be connected with a straight cable. In case of medium dependent interface crossover (MDIX) on the peer device, the C1000-24T-4G-L switch model requires ports 2,4,12 and 20 to be connected with a straight cable, and ports 7,14,15 and 23 to be connected with a cross-over cable. The Automatic Polarity Correction feature is the function that automatically corrects when the polarity of RX (received data) is reversed. Normally, one differential signal includes "+" and "-", and RX+ connects to TX+, RX- connects to TX-. With the Automatic Polarity Correction support on PHY 88E1680, RX- can connect to TX+, RX+ connect to TX-.


Note

The Cisco Catalyst 1000 Series Fast Ethernet Switches support only 10/100 downlink ports.

Console Port

The console ports connect the switch to a PC running Microsoft Windows or to a terminal server.

RJ-45 console port (EIA/TIA-232) connection uses an RJ-45-to-DB-9 female cable.

USB Type A Port

The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB keys).

The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB devices with port densities of 128 MB, 256 MB, 1 GB, 4 GB, and 8 GB are supported). Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy, as well as the ability to format the flash device with a FAT file system.

It provides you with the ability to automatically upgrade the internal flash with the USB drive's configuration and image for emergency switch recovery using USB auto-upgrade. This feature checks the internal flash for a bootable image and configuration and if either image or the configuration is not available, then the USB drive is checked for boot images and configuration. If the boot image and configuration are available, these are copied to flash for the reboot.

SFP Module Slots


Note

The Cisco Catalyst 1000 Series Fast Ethernet Switches do not support SFP+ module slots.

The switch has four 1G SFP or 10G SFP+ module slots. The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These transceiver modules are field replaceable, and provide the uplink interfaces when installed in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper connections. The SFP slots support only SFP modules.

Note

If you insert a 10G SFP+ in to a 1G SFP module slot and vice versa, you need to clear the existing configuration by running the default-interface <interface-number> command on the mapped ports. For more information about the command, refer to the Software Configuration Guide.

LEDs

You can use the switch system and port LEDs to monitor switch activity and performance.

Note

Physically, there is no amber LED on the device. For all LED-related information of the device, run the show hardware led command in privileged EXEC mode.

RJ-45 ports and SFP-module slots have port LEDs. These LEDs, as a group or individually, provide information about the switch and about the individual ports.

Internal Power Supply

All the switches are powered through their internal power supplies. The internal power supply is an autoranging unit that supports input voltages between 100 and 240 VAC (max of 90V to 264V). The AC frequency range of the power supply is 50Hz/60Hz. Plug the AC power cord into the AC power connector and into an AC power outlet.

Security Slot

The switches have security slots on the rear panel. You can install an optional cable lock, such as the type that is used to secure a laptop computer, to secure the switch.
