8 SFP slots (sockets)Fiber mini switch for a quick and plug and play switching between fiber optical cables with distances up to 120 km, any MSA 1.25 SFP transceiver supported Applications 8 SFP slots (sockets) Gigabit Fiber mini switch can be used not only in any size ISP's or Telecom Operators who want to develop PTP type FTTH/FTTB network. What is SFP port/slot? To figure this out, you must know what SFP is in the first place. SFP, an acronym of small form-factor pluggable, is a compact and hot-pluggable transceiver used for both telecommunication and data communication applications. It connects motherboards of network devices (such as switches and routers) with optical or copper. Sep 27, 2018 The switch can operate without a network module, but a blank module (with no ports or SFP slots) is available and should be installed when uplink ports are not required. Note The switch generates logs when you insert or remove a network module with SFP slots.

This section describes the front panel components:
Figure 1. Catalyst 2960X-48FPD-L Front Panel. The Catalyst 2960X-48FPD-L switch is shown here as an example. Other switches have similar components.
PoE and PoE+ Ports
The ports provide PoE+ support for devices compliant with IEEE 802.3af, IEEE 802.3at, and ePoE and also provide Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
The maximum switch power output is either 740 W or 370 W, depending on the switch model. Intelligent power management allows flexible power allocation across all ports.
For switches with a 740 W power budget, you can budget the PoE and PoE+:
For switches with a 370 W power budget, you can budget the PoE and PoE+:
On a per-port basis, you 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 maximum cable length is 328 feet (100 meters). The 10BASE-T, 100BASE-TX, 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.
Cisco intelligent power management capabilities include enhanced power negotiation, power reservation, and per-port power policing. For information about configuring and monitoring PoE ports, see the switch software configuration guide on Cisco.com.
10/100/1000 Ports
The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.

Management Ports
The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
The 10/100 Ethernet management port connection uses a standard RJ-45 crossover or straight-through cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.
If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not require special drivers.
The 4-pin mini-Type B connector resembles the 5-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B.
Figure 2. USB Mini-Type B Port. This illustration shows a 5-pin mini-Type B USB port.
With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console port without affecting Windows HyperTerminal operations.
The console output always goes to both the RJ-45 and the USB console connectors, but the console input is active on only one of the console connectors at any one time. The USB console takes precedence over the RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive. Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45 console if the USB console has been activated and no input activity has occurred on the USB console for a specified time.
After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and reconnect the USB cable to reactivate the USB console. For information on using the CLI to configure the USB console interface, see the software guide.
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 USB Type A port provides these features:
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, 8 GB are supported). When combined with stacking, you can upgrade other switches in the stack from an USB key inserted in any switch within the stack. 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 and SFP+ Module Slots
The switch has either two or four 1-Gigabit SFP or two 10-Gigabit SFP+ module slots. The slots marked SFP+ support both SFP and SFP+ modules. The SFP slots support only the SFP modules.

LEDs
You can use the switch LEDs to monitor switch activity and its performance.
Figure 3. Switch LEDs and Mode Button for the Catalyst 2960-X Switch. This figure shows the switch LEDs and the Mode button that you use to select a port mode.
4 RPS = redundant power system—only on switch models that support RPS.
6 Only on switch models that support stacking.
System LED
RPS LED
The RPS LED is only available on switch models that have an RPS port.
Master LED
Port LEDs and Modes
The port and module slots each has a port LED. As a group or individually, the LEDs show information about the switch and about the ports.
To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change.
If your switches are stacked and you press the Mode button on any switch, all the switches display the same selected mode. For example, if you press the Mode button on the stack master to display SPEED, all the other stack members display SPEED.
Even if PoE mode is not selected, this LED still shows PoE problems if they are detected.
STACK LED
The STACK LED shows the sequence of member switches in a stack. Up to eight switches can be members of a stack. The first eight port LEDs show the switch member number. For example, if you press the Mode button and select Stack, the port LED 1 blinks green. The LEDs for port 2 and 3 are solid green, as these represent the member numbers of other stack members. The other port LEDs are off because there are no more members in the stack.
Figure 4. STACK LED. This figure shows the LEDs on the first switch, which is stack member number 1.
When you select the STACK LED, the respective STACK LEDs are green when the stack ports (on the switch rear panel) are up, and the respective Stack LEDs are amber when the ports are down. SFP+ module port LEDs 1 and 2 on the switch show the status for stack ports 1 and 2, respectively.
If the port LEDs are green on all the switches in the stack, the stack is operating at full bandwidth. If any port LED is not green, the stack is not operating at full bandwidth.
Console LEDs
The console LEDs show which console port is in use. If you connect a cable to a console port, the switch automatically uses that port for console communication. If you connect two console cables, the USB console port has priority.
Ethernet Management Port LED
Rear Panel
The rear panel of the Catalyst 2960-X switches have a FlexStack-Plus module slot, a fan exhaust, an RPS connector, and an AC power connector.
FlexStack-Plus Ports and LEDs
The stacking-capable switch models support stacking with the optional stack kit. It has the FlexStack-Plus module (hot-swappable) that inserts in the slot located in the switch rear panel, and a 0.5-meter FlexStack cable to connect the FlexStack-Plus module ports.
RPS Connector
The Cisco RPS 2300 (model PWR-RPS2300) supports the Catalyst 2960-X switch.
What Is Sfp Slot
Connect the switch and the redundant power system to different AC power sources.
Use this cable for the RPS: CAB-RPS2300-E.
Cisco RPS 2300
The Cisco RPS 2300 is a redundant power system that can support six external network devices and provide power to one or two failed devices at a time. It senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic. For more information, see the Cisco Redundant Power System 2300 Hardware Installation Guide on Cisco.com at this URL: http://www.cisco.com/en/US/products/ps7148/prod_installation_guides_list.html
The Cisco RPS 2300 has two output levels: –52 V and 12 V with a total maximum output power of 2300 W.
All supported and connected switches can simultaneously communicate with the RPS 2300. You can configure these RPS 2300 features through the switch software:
AC Power Connector
The switch is powered through the internal power supply. The internal power supply is an autoranging unit that supports input voltages between 100 and 240 VAC. Use the supplied AC power cord to plug it into an AC power outlet.
Management Options
Network Configurations
See the switch software configuration guide on Cisco.com for network configuration concepts and examples of using the switch to create dedicated network segments and interconnecting the segments through Fast Ethernet and Gigabit Ethernet connections.
