SFP and SFP+ Transceiver Module Ports
The chassis contains 16/24/32/40 ports of 10-Gigabit Ethernet SFP+ or 100BASE-FX fiber-optic transceiver
modules. All ports support 1-Gigabit SFP, 10-Gigabit SFP+, or 100BASE-FX fiber-optic SFP modules with
two 40-Gigabit uplink ports on selected switch models.
The ports also support Cisco Trust Security (CTS) and virtual switch link (VSL) and can operate as an Instant
Access (IA) Parent in both 1-Gigabit, 10-Gigabit modes and 40-Gigabit modes.
The SFP and SFP+ transceiver 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 transceiver modules have LC connectors for fiber-optic connections or RJ-45 connectors for
copper connections.
For a list of supported SFP and SFP+ modules, see the switch data sheet: http://www.cisco.com/c/en/us/
products/collateral/switches/catalyst-6800-series-switches/datasheet-c78-734470.html.
The odd-numbered ports are on the upper row and the even-numbered ports on the lower row. The following
figures show how the ports and the LEDs are numbered on different switch models. This section also explains
the port mapping between 10-Gigabit and 40-Gigabit ports.

Power Supply Slots
The chassis has two power supply slots that accept either AC-input or DC-input power supplies, or one of
each. The chassis is delivered with power supplies pre-installed in the power supply slots. If only one power
supply is ordered, then a blank cover is installed in the empty power supply slot, which must remain installed
if a power supply is not installed.

Management Port
The management port is a 10/100/1000 copper Ethernet port directly connected to the route processor. The
switch also has a fibre port that can be used as the Ethernet Management port. It supports TFTP image
downloading, network management, SNMP, Telnet, and SSH connections. The management port is isolated
from other ports in the system in a dedicated management VRF; it is not part of the EARL forwarding logic.
The management port provides direct access to the CPU, even when the system is heavily loaded.
The management port is a Layer 3 port in host mode, and only accepts traffic that terminates on the router.
This port does not route packets between itself and other ports. The port processes only the following packet
types and properly enqueues them:
•Address Resolution Protocol (ARP)
•IPv4 unicast
•IPv6 unicast
•Cisco Discovery Protocol (CDP)

Mini USB Type B Console Port
The Mini USB 2.0 Type B console port functions as a second console connection to the route processor. The
USB console port connection uses a Mini USB 2.0 cable. The USB console interface speed is same as the
RJ-45 console interface speed.
Windows computers require a driver for the USB port. Before using the USB port, you must download the
required driver to your computer from https://software.cisco.com/download/
release.html?mdfid=282979369&softwareid=282855122&release=3.1
By default, USB-prefer mode is enabled for the port; but it can be overridden using the command-line interface
(CLI). When this port is in the USB-prefer mode, the RJ-45 console port will be disabled, if both the ports
are connected. For more information on using the CLI to configure the USB console interface, see the Catalyst
6500 Software Configuration Guide.

USB Type A Port
The USB 2.0 Type A port (disk0) is the only external storage interface for this switch. The port is connected
to the route processor, which allows the Cisco IOS software to access the port. 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. The software also provides the ability to format the flash device with a
FAT file system (FAT32 and FAT16).

Console Port
The console port is an RJ-45 port that provides universal asynchronous receiver/transmitter (UART) support
to access the route processor with a serial console running at 9600 baud rate with 8 bits for data, no parity bit,
and 1 stop bit.

Fan Tray
The fan tray is responsible for cooling the entire chassis and interfacing with environmental monitors to trigger
alarms when conditions exceed thresholds. The fan tray supports Online Insertion and Removal (OIR).
The fan tray contains four high-efficiency fans with variable speed settings and thermal sensors. If one fan
fails, the speed of the others is increased and a minor alarm is triggered. If a major fan tray failure occurs, the
system is shut down. The individual fans are not field replaceable; the entire fan tray must be replaced in the
event of a major fan tray failure. See Removing the Fan Tray for additional information about the fan.
