Ports

10/100BASE-T Ports

You can set the 10/100BASE-T 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).

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

PoE and PoE+ Ports

Chapter 1 Product Overview

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.

Statement 1072

The 10/100BASE-T PoE+ ports on the Cisco CGS-2520-16S-8PC and Cisco CGS-2520-16S-8PC-C
models provide:

• Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and support for

IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port).

• Support for prestandard Cisco powered devices.

• Configurable support for Cisco intelligent power management, including:

–

enhanced power negotiation

–

power reservation

–

per-port power policing

Each power supply module can support an equivalent PoE load of two PoE+ ports or four PoE ports.
When both power supply modules are installed, the system has enough power to support four PoE+
ports, or eight PoE ports.

If ports are designated as high priority and low priority PoE or PoE+ ports at the command line
interface (CLI), and one power supply module fails or is removed, power to the high priority ports
is maintained, and power to the low priority ports is dropped. When assigning priority to PoE or
PoE+ ports, it is important to assign priorities on the basis of power supply capacity.

For information about configuring and monitoring PoE ports, see the CGS 2520 Switch Software
Configuration Guide on Cisco.com.

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

Ethernet Ports” section on page 2-24 and the “Connector and Cable Specifications” section on page B-1.

Cisco CGS 2520 Hardware Installation Guide

OL-31444-01

Chapter 1 Product Overview

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

Dual-Purpose Gigabit Ethernet 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 CGS 2520 Switch Software Configuration Guide on Cisco.com.

For more information on the SFP module ports see:

• SFP Modules, page 1-5

• SFP Module Patch Cable, page 1-6

Ports

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

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.

This section contains the following alarm port information:

• Alarm Input, page 1-7

• Alarm Output, page 1-7

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 the

“Alarm LEDs” section on page 1-10 for the LED descriptions.

Alarm Output

OL-31444-01

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 the “Alarm Port” section on 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

• USB mini-Type B console port (5-pin connector); the USB 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.

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” section on 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.

Chapter 1 Product Overview

LEDs

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.

Figure 1-5 USB Mini-Type B Port

The configurable inactivity timeout reactivates the RJ-45 console port if the USB console port is
activated, but no input activity occurs on it for a specified time period. When the USB 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 console interface, see the switch software
guide.

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

Installation Guidelines

Warning

To prevent airflow restriction, allow clearance around the ventilation openings to be at least:

1.75 in. (4.4 cm).

Statement 1076

Installation Guidelines

Before installing the switch, verify that these guidelines are met:

• Cabling must be kept away from sources of electrical noise, such as radios, power lines, and

fluorescent lighting fixtures. Make sure that the cabling is away from other devices that might
damage the cables.

• Operating environment is within the temperature ranges listed in the “Switch Specifications” section

on page A-1.

• Relative humidity around the switch does not exceed 95 percent (noncondensing).

• Altitude at the installation site is not higher than 10,000 feet.

• For 10/100 and 10/100/1000 fixed ports, cable lengths from the switch to connected devices are not

more than 328 feet (100 meters).

• For cable lengths for small-form-factor pluggable (SFP)-module connections, see the “SFP Module

Cables” section on page B-4 and the module documentation.

• Airflow around the switch and through the vents is unrestricted. To prevent overheating, the switch

must meet the minimum clearance of 1.75 inches (4.4 cm) at the top and bottom. For clearances
needed for wall mounting, see specifications in “Wall-Mounting” section on page 2-16.

Note If the switch is installed in a closed or multirack assembly, take into consideration that the

temperature around the switch might be greater than normal room temperature and that special
accommodations in clearance must be made.

Verifying Switch Operation

Before installing the switch in a rack or on a wall, you should power on the switch and verify that the
switch passes the power-on self-test (POST).

To wire the switch to the power source, see the “Power Supply Module Installation” section on page 3-2.

When the switch begins POST, the System LED blinks green, and the other LEDs stay green. When the
switch passes POST, the System LED turns green. The other LEDs turn off and return to their operating
status. If the switch fails POST, the System LED is amber.

Note Contact Cisco Systems immediately if your switch fails POST.

After a successful POST, disconnect the power from the switch.
