Ports and Slots

Note: Different configurations are available. Not all ports or slots are present in all configurations.

Product Overview

Ports and Slots

10/100/1000 BASE-T Downlink Ports

You can set the 10/100BASE-T downlink ports to operate at 10 or 100 Mb/s in full-duplex or half-duplex mode. You can

also set these ports for speed and duplex autonegotiation in compliance with IEEE 802.3AB. (The default setting is

autonegotiate.) When set for autonegotiation, the port senses the speed and duplex settings of the attached device and

advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best

connection (that is, the fastest line speed that both devices support, and full-duplex transmission if the attached device

supports it) and configures itself accordingly. In all cases, the attached device must be within 328 feet (100 meters).

100BASE-TX traffic requires Category 5 cable. 10BASE-T traffic can use Category 3 or Category 4 cables.

When connecting the switch to workstations, servers, routers, and Cisco IP phones, make sure that the cable is a

straight-through cable.

You can use the mdix auto interface configuration command in the command-line interface (CLI) to enable the automatic

medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled, the switch detects

the required cable type for copper Ethernet connections and configures the interfaces accordingly. For configuration

information for this feature, see the switch software configuration guide or the switch command reference.

10/100/1000BASE-T Uplink Ports

The IEEE 802.3u 10/100/1000BASE-T uplink ports provide full-duplex 10, 100 or 1000 Mb/s connectivity over Category

5 unshielded twisted pair (UTP) copper cabling. The default setting is autonegotiate. The cable can be up to 100 m

(0.1 km) in length.

100/1000 Mb/s SFP Module Downlink Slots

The IEEE 802.3u 100 Mb/s SFP module downlink slots provide full-duplex 100 Mb/s connectivity over multi-mode (MM)

fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic transceiver module that accepts a dual

LC connector. Check the SFP specifications for the cable type and length.

100/1000 Mb/s SFP Module Uplink Slots

The IEEE 802.3u 100 Mb/s SFP module uplink slots provide full-duplex 100 or 1000 Mb/s connectivity over multi-mode

(MM) fiber cables or single-mode (SM) fiber cables. These ports use a SFP fiber-optic transceiver module that accepts

a dual LC connector. Check the SFP specifications for the cable type and length.

Dual-Purpose Fast Ethernet Downlink Ports

You can configure the dual-purpose Fast Ethernet Downlink ports on the switch as either 10/100BASE-T ports or as 100

Mb/s SFP-module ports. You can set the 10/100 ports to autonegotiate, or you can configure them as fixed 10 or 100

Mb/s ports.

By default, the switch selects the medium for each dual-purpose port (10/100BASE-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.

Product Overview

Ports and Slots

Dual-Purpose Gigabit Ethernet Uplink or Downlink Ports

You can configure the dual-purpose Gigabit Ethernet uplink or downlink ports on the switch as either 10/1001000BASE-T

ports or as 100/1000 Mb/s SFP-module ports. You can set the 10/100/1000BASE-T 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.

Management Ports

You can connect the switch to a PC running Microsoft Windows or to a terminal server through either the RJ-45 console

port or the USB mini-Type B console port, also referred to as the USB-mini console port. These ports use the following

connectors:

RJ-45 console port uses an RJ-45-to-DB-9 female cable.

USB-mini console port (5-pin connector) uses a USB Type A-to-5-pin mini-Type B cable.

The USB-mini console interface speeds are the same as the RJ-45 console interface speeds.

To use the USB-mini console port, you must install the Cisco Windows USB device driver on the device that is connected

to the USB-mini console port and that is running Microsoft Windows.

Note: For information about downloading the Cisco USB device driver, see Installing the Cisco Microsoft Windows XP,

2000, Vista, 7, 8, and 10 USB Device Driver, page 48.

With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the console port does not

affect Windows HyperTerminal operations. Mac OS X or Linux require no special drivers.

Note: The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors, but they are not compatible. Use

only the 5-pin mini-Type B. See Figure 2 on page 4.

Figure 2

USB Mini-Type B Port

The configurable inactivity timeout reactivates the RJ-45 console port if the USB-mini console port is activated, but no

input activity occurs for a specified time period. When the USB-mini console port deactivates due to a timeout, you can

restore its operation by disconnecting and reconnecting the USB cable. For information on using the CLI to configure the

USB-mini console interface, see the switch software guide.

Product Overview

Power Connectors

DC Power Connector

You connect the DC power to the switch through the front panel connectors. The switch has a dual-feed DC power

supply; two connectors provide primary and secondary DC power (DC-A and DC-B). The DC power connectors are near

the top right of the front panel. See Figure 1 on page 2. Each power connector has an LED status indicator.

The switch power connectors are attached to the switch chassis. Each power connector has screw terminals for

terminating the DC power. All connectors are attached to the switch front panel with the provided captive screws.

The power connector labeling is on the panel. The positive DC power connection is labeled “+”, and the return

connection is labeled “-”.

The switch can operate with a single power source or with dual power sources. When both power sources are

operational, the switch draws power from the DC source with the higher voltage. If one of the two power sources fail,

the other continues to power the switch.

Alarm Connector

You connect the alarm signals to the switch through the alarm connector. The switch supports two alarm inputs and one

alarm output relay. The alarm connector is on the bottom right of the front panel. See Figure 3 on page 5.

The alarm connector provides six alarm wire connections. The connector is attached to the switch front panel with the

provided captive screws.

Figure 3

Alarm Connector

Both alarm input circuits can sense if the alarm input is open or closed. The alarm inputs can be activated for

environmental, power supply, and port status alarm conditions. From the CLI, you can configure each alarm input as an

open or closed contact.

The alarm output circuit is a relay with a normally open and a normally closed contact. The switch is configured to detect

faults that are used to energize the relay coil and change the state on both of the relay contacts: normally open contacts

close, and normally closed contacts open. The alarm output relay can be used to control an external alarm device, such

as a bell or a light.

See the switch software configuration guide for instructions on configuring the alarm relays.
