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 .

Figure 1-4 Power-Input Terminal

Ports

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.

If the device does not support auto-negotiation, you can set the switch port speed and duplex parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. With auto-MDIX enabled, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a 10/100/1000 Ethernet port, regardless of the type of connected device.

See the switch software configuration guide or the switch command reference on Cisco.com for more information about auto-negotiation and auto-MDIX.

Connecting Devices to the Ethernet Ports

If auto-MDIX is disabled, use the guidelines in Table 2-1 to select the cable for connecting the 10/100/1000 Ethernet ports to other devices.

See the “Connector and Cable Specifications” section on page B-1 for cable-pinout descriptions.

Figure 2-24 Connecting to an Ethernet Port

Connecting to the 10/100 PoE+ Ports

The Cisco CGS-2520-16S-8PC switch (and the CGS-2520-16S-8PC-C switch) 10/100 PoE+ ports have the same auto-negotiation settings and cabling requirements as those in the “Connecting to the 10/100

and 10/100/1000 Ports” section on page 2-25. These ports provide PoE power.

See the “PoE and PoE+ Ports” section on page 1-4 for information on the cables and connectors.

OL-31444-01

The ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

On a per-port basis, you can control whether or not a port automatically provides power to a connected IP phone or an access point.

Power Supply Modules

For information on the power supply modules, see the “Power Supply Features” section on page 1-14.

Table 3-1 Power Supply Modules

Model Description

PWR-RGD-LOW-DC Low-voltage DC. For voltage information, see Table A-8 on page A-4

PWR-RGD-AC-DC High-voltage AC or DC. For voltage information, see Table A-7 on page A-4

PWR-RGD-AC-DC-C (For China) High-voltage AC or DC. For voltage information, see Table A-7

Note 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.

• Ping End Device, page 4-4

• Spanning Tree Loops, page 4-4

Bad or Damaged Cable

Always examine the cable for marginal damage or failure. A cable might be just good enough to connect at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors. You can identify this problem because the port has many packet errors or it constantly flaps (loses and regains link).

Chapter 4 Troubleshooting

• Exchange the copper or fiber-optic cable with a known good cable.

• Look for broken or missing pins on cable connectors.

• Rule out any bad patch panel connections or media convertors between the source and the

destination. If possible, bypass the patch panel, or eliminate media convertors (fiber-optic-to-copper).

• Try the cable in another port to see if the problem follows the cable.

Ethernet and Fiber-Optic Cables

Make sure that you have the correct cable:

• For Ethernet, use Category 3 copper cable for 10 Mb/s UTP connections. Use either Category 5,

Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s connections.

• Verify that you have the correct fiber-optic cable for the distance and port type. Make sure that the

connected device ports match and use the same type encoding, optical frequency, and fiber type.

• Determine if a copper crossover cable was used when a straight-through was required or the reverse.

Enable auto-MDIX on the switch, or replace the cable. See Tab le 2-1 for recommended Ethernet cables.

Link Status

Verify that both sides have link. A broken wire or a shutdown port can cause one side to show link even though the other side does not have link.

A port LED that is on does not guarantee that the cable is functional. It might have encountered physical stress, causing it to function at a marginal level. If the port LED does not turn on:

• Connect the cable from the switch to a known good device.

4-2

Cisco CGS 2520 Hardware Installation Guide

OL-31444-01

Chapter 4 Troubleshooting

• Make sure that both ends of the cable are connected to the correct ports.

• Verify that both devices have power.

• Verify that you are using the correct cable type. See the “Connector and Cable Specifications”

section on page B-1 for information.

• Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable,

and then reconnect it.

10/100 and 10/100/1000 Port Connections

A port appears to malfunction:

• Verify the status of all ports. See Table 1-8 on page 1-11 for descriptions of the LEDs and their

meanings.

• Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or

shut down. Re-enable the port if necessary.

• Verify the cable type. See the “Connector and Cable Specifications” section on page B-1

Diagnosing Problems

10/100 PoE+ Port Connections

A powered device connected to a PoE+ port does not receive power:

• Verify the status of all the ports. See Table 1-8 for descriptions of the LEDs and their meanings.

• Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or

shutdown. Re-enable the port if necessary.

• Verify the cable type. Many legacy powered devices, including older Cisco IP phones and access

points that do not fully support IEEE 802.3af or IEEE 802 (PoE and PoE+ standards) might not support PoE or PoE+ when connected to the switch by a crossover cable. Replace the crossover cable with a straight-through cable.

Caution Noncompliant cabling or powered devices can cause a PoE or PoE+ port fault. Use only compliant

cabling to connect Cisco prestandard IP Phones, and wireless access points, IEEE 802.3af or IEEE

802.3at-compliant devices.

SFP Module

Use only Cisco SFP modules. Each Cisco module has an internal serial EEPROM that is encoded with security information. This encoding verifies that the module meets the requirements for the switch.

• Inspect the SFP module. Exchange the suspect module with a known good module.

• Verify that the module is supported on this platform. (The switch release notes on Cisco.com list the

SFP modules that the switch supports.)

• Use the show interfaces privileged EXEC command to see if the port or module is error-disabled,

disabled, or shutdown. Re-enable the port if needed.

OL-31444-01

• Make sure that all fiber-optic connections are clean and securely connected.

Cisco CGS 2520 Hardware Installation Guide

Diagnosing Problems

Interface Settings

Verify that the interface is not disabled or powered off. If an interface is manually shut down on either side of the link, it does not come up until you re-enable the interface. Use the show interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or shut down on either side of the connection. If needed, re-enable the interface.

Ping End Device

Ping from the directly connected switch first, and then work your way back port by port, interface by interface, trunk by trunk, until you find the source of the connectivity issue. Make sure that each switch can identify the end device MAC address in its Content-Addressable Memory (CAM) table.

Spanning Tree Loops

STP loops can cause serious performance issues that look like port or interface problems.

A unidirectional link can cause loops. It occurs when the traffic sent by the switch is received by the neighbor, but the traffic from the neighbor is not received by the switch. A broken cable, other cabling problems, or a port issue could cause this one-way communication.

Chapter 4 Troubleshooting

You can enable UniDirectional Link Detection (UDLD) on the switch to help identify unidirectional link problems. For information about enabling UDLD on the switch, see the “Understanding UDLD” section in the switch software configuration guide on Cisco.com.

Switch Performance

• Speed, Duplex, and Auto-Negotiation, page 4-4

• Auto-Negotiation and Network Interface Cards, page 4-5

• Cabling Distance, page 4-5

Speed, Duplex, and Auto-Negotiation

Port statistics that show a large amount of alignment errors, Frame Check Sequence (FCS), or late collisions errors, might mean a speed or duplex mismatch.

A common issue occurs when duplex and speed settings are mismatched between two switches, between a switch and a router, or between the switch and a workstation or server. Mismatches can happen when manually setting the speed and duplex or from auto-negotiation issues between the two devices.

To maximize switch performance and to ensure a link, follow one of these guidelines when changing the duplex or the speed settings.

• Let both ports autonegotiate both speed and duplex.

• Manually set the speed and duplex parameters for the interfaces on both ends of the connection.

4-4

• If a remote device does not autonegotiate, use the same duplex settings on the two ports. The speed

parameter adjusts itself even if the connected port does not autonegotiate.

Cisco CGS 2520 Hardware Installation Guide

OL-31444-01

Chapter 4 Troubleshooting

Auto-Negotiation and Network Interface Cards

Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch ports and interfaces autonegotiate. Laptops or other devices are commonly set to autonegotiate, yet sometimes issues occur.

To troubleshoot auto-negotiation problems, try manually setting both sides of the connection. If this does not solve the problem, there could be a problem with the firmware or software on the NIC. You can resolve this by upgrading the NIC driver to the latest version.

Cabling Distance

If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance from the switch to the connected device meets the recommended guidelines. See the “Cables and

Adapters” section on page B-4.

APPENDIX

10/100 Ethernet Ports

OL-31444-01

The 10/100 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts with internal crossovers. These ports have the send (TD) and receive (RD) signals internally crossed so that a twisted-pair straight-through cable and adapter can be attached.

Connector Specifications

Note You can use the mdix auto interface configuration command in the CLI to enable the automatic

Appendix B Connector and Cable Specifications

When connecting 10/100 ports to devices such as servers, workstations, and routers, you can use a two or four twisted-pair straight-through cable wired for 10BASE-T and 100BASE-TX. Figure B-5 shows the two twisted-pair straight-through cable schematics. Figure B-7 shows the four twisted-pair straight-through cable schematics.

When connecting the ports to other devices, such as switches or repeaters, you can use a two or four twisted-pair crossover cable. Figure B-6 shows the two twisted-pair crossover cable schematics.

Figure B-8 shows the four twisted-pair crossover cable schematics.

If auto-MDIX is disabled, use a straight-through cable to connect ports when only one port is labeled with an X. Use a crossover cable to connect ports when both ports are labeled with an X or when both ports are not labeled with an X.

You can use Category 3, 4, or 5 cabling when connecting to 10BASE-T-compatible devices. You must use Category 5 (or higher) cabling when connecting to 100BASE-TX-compatible devices.

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. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.

IP Settings

Cisco CGS 2520 Hardware Installation Guide

C-6

You need this information:

• Switch IP address

• Subnet mask (IP netmask)

• Default gateway (router)

• Enable secret password

OL-31444-01

Appendix C Configuring the Switch with the CLI Setup Program

• Enable password

• Telnet password

Completing the Setup Program

Follow these steps to complete the setup program and to create an initial configuration for the switch:

Step 1 Enter Ye s at these two prompts.

Would you like to enter the initial configuration dialog? [yes/no]: yes

At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'.

Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system.

Would you like to enter basic management setup? [yes/no]: yes

Entering the Initial Configuration Information

Step 2 Enter a host name for the switch, and press Return.

On a command switch, the host name is limited to 28 characters and on a member switch to 31 characters. Do not use -n, where n is a number, as the last character in a host name for any switch.

Enter host name [Switch]: host_name

Step 3 Enter an enable secret password, and press Return.

The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is in plain text.

Enter enable secret: secret_password

Step 4 Enter an enable password, and press Return.

Enter enable password: enable_password

Step 5 Enter a virtual terminal (Telnet) password, and press Return.

The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.

Enter virtual terminal password: terminal-password

Step 6 (Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts.

You can also configure SNMP later through the CLI. To configure SNMP later, enter no.

Configure SNMP Network Management? [no]: no

OL-31444-01

Step 7 Enter the interface name (physical interface or VLAN name) of the interface that connects to the

management network, and press Return. For this release, always use vlan1 as that interface.

Enter interface name used to connect to the management network from the above interface summary: vlan1

Entering the Initial Configuration Information

Step 8 Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP

address and subnet masks shown below are examples.

Configuring interface vlan1: Configure IP on this interface? [yes]: yes IP address for this interface: 10.4.120.106 Subnet mask for this interface [255.0.0.0]: 255.0.0.0

Step 9 Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member

switch or as a standalone switch.

If you enter N, you can configure the switch as a command switch later through the CLI. To configure it later, enter no.

Would you like to enable as a cluster command switch? [yes/no]: no

You have completed the initial configuration of the switch, and the switch displays its configuration. This is an example of the configuration output:

The following configuration command script was created: hostname switch1 enable secret 5 $1$Ulq8$DlA/OiaEbl90WcBPd9cOn1 enable password enable_password line vty 0 15 password terminal-password no snmp-server ! no ip routing

Appendix C Configuring the Switch with the CLI Setup Program

! interface Vlan1 no shutdown ip address 10.4.120.106 255.0.0.0 ! interface FastEthernet1/0/1 ! interface FastEthernet1/0/2

interface FastEthernet1/0/3 ! ...<output abbreviated> end

Step 10 These choices appear:

[0] Go to the IOS command prompt without saving this config.

[1] Return back to the setup without saving this config.

[2] Save this configuration to nvram and exit.

If you want to save the configuration and use it the next time the switch reboots, select option 2 to save it in NVRAM.

Enter your selection [2]:2

Make your selection, and press Return.
