10/100 Fast Ethernet Ports

You can set the 10/100 ports on the switch to operate in any combination of half duplex, full duplex, or 10 or 100 Mb/s. You can set the ports for speed and duplex auto-negotiation. The default setting is auto-negotiate.

When set for auto-negotiation, the switch determines the speed and duplex settings of the attached device, and advertises its own capabilities. If the connected device also supports auto-negotiation, the switch negotiates the best connection (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).

PoE Ports

Warning

Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security.

The 10/100 PoE ports on the Cisco CGS-2520-16S-8PC-C switches provide PoE support for devices that are compliant with IEEE 802.3af. The Cisco prestandard PoE is also supported for Cisco IP Phones and Cisco Aironet Access Points. The PoE ports on the switch deliver up to 15.4 W of PoE. Any four of the eight ports are designated as high priority PoE ports, while other four ports are designated as low priority

Statement 1072

Cable Side

Chapter 1 Product Overview

PoE ports. When both the power supply modules are installed, the system has enough power to support all the eight ports as PoE ports. In case one of the power supply module fails, the power to the low priority PoE ports is dropped, while power to the high priority PoE ports remains uninterrupted.

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 10/100 PoE ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 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.

For information about configuring and monitoring PoE ports, see the switch software configuration guide on Cisco.com.

For information about port connections and port specifications, see the Connecting Devices to the

Ethernet Ports, page 2-24 and the Connector and Cable Specifications, page B-1.

Note The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.

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-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.

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 the supported SFP modules listed in Table 1 -2.

Alarm Ports

Alarm Input

Alarm Output

207234

The switch has four alarm inputs and one alarm output. The alarm setting is open or closed.

• Open means that the normal condition has current flowing through the contact (referred to as a

normally closed contact). The alarm is generated when the current stops.

• Closed means that no current flows through the contact (referred to as a normally open contact). The

alarm is generated when the current flows.

The alarm input is a dry-contact alarm port. You can connect up to four alarm inputs from devices, such as a door, a temperature gauge, or a fire alarm, to the alarm port. You can use the CLI to set the alarm severity to minor, major, or critical. An alarm generates a system message and turns on an LED. See

Alarm LEDs, page 1-9 for the LED descriptions.

The alarm output can be configured as a minor or major alarm. Output alarms often control an external alarm, such as a bell or a light. To connect an external alarm device to the relay, connect two relay contact wires to complete the electrical circuit. See Alarm Port, page B-3 for information on the alarm pinouts.

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 console port.

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

Chapter 1 Product Overview

• USB mini-Type B console port (5-pin connector); the USB connection uses a USB Type A-to-5-pin

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

To use the USB console port, you must install the Cisco Windows USB device driver on the device that is connected to the USB console port (device running with Microsoft Windows).

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

Windows USB Device Drivers, page C-4.

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. They are not compatible.

Use only the 5-pin mini-Type B. See Figure 1-5.
