Ensuring Safety

Use the following guidelines to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations during installation, so be alert.

Note Power supplies in the Catalyst 5002 switch do not have on/off switches.

Warning Only trained and qualified personnel should install or replace this equipment.

Always turn all power supplies off (the position marker zero), and unplug all power cords before installing or removing a chassis.
Keep the chassis area clear and free of dust during and after installation.
Keep tools and chassis components off the floor and away from foot traffic.

Avoid wearing jewelry and securely fasten any loose clothing that could get caught in the chassis.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Following Basic Electrical Safety Guidelines

When working with electrical equipment, exercise these basic safety guidelines:

Never install equipment that appears to be damaged.
Locate the emergency power-off switch for the room in which you are working before beginning any procedures that require access to the chassis interior.
Disconnect all power and external cables before installing or removing a chassis.
Do not work alone when potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Examine your work area carefully for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Following Telephone Wiring and Network Cabling Safety Rules

Use the following safety rules when working with any equipment that is disconnected from a power source but still connected to telephone wiring or other network cabling:

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic boards or components are improperly handled. ESD can result in complete or intermittent failures of electronic components. Guidelines for preventing ESD damage are as follows:

Always use an antistatic wrist or ankle strap and ensure that it makes good skin contact. For the Catalyst 5002 switch, use the type shown in Figure 1. For the Catalyst 5000 switch, use one of the two types of antistatic wrist straps shown in Figure 2. For the Catalyst 5500 switch, use the type shown in Figure 3.
If you use the wrist strap with an alligator clip, connect the alligator clip to one of the captive installation screws on the chassis, an installed module, or a power supply. If you use the wrist strap with a banana-plug connector, insert the banana-plug connector into the grounding receptacle on the rear of the chassis. See Figure 1, Figure 2, and Figure 3.

Figure 1 Placement of ESD Wrist Strap on the Catalyst 5002 Switch

Figure 2 Types and Placement of ESD Wrist Straps on the Catalyst 5000 Switch

Figure 3 Placement of ESD Wrist Strap on the Catalyst 5500 Switch

Handle supervisor engine modules and switching modules by the metal carrier edges and handles only; the metal carriers have electromagnetic interference (EMI) shielding. Never touch the printed circuit boards or connector pins.
After removing a module, place it component-side up on an antistatic surface or in a static-shielding bag. If you plan to return the module to the factory, immediately place it in a static-shielding bag.
Avoid contact between the modules and clothing; the wrist strap protects the module from ESD voltages on the body, but ESD voltages on clothing can still cause damage.
Handle modules without metal carriers by the edges only.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Switching Modules Installation and Configuration

All Catalyst 5000 series switches support hot swapping, which lets you install, remove, replace, and rearrange switching modules without turning off the system power. When the system detects that a switching module has been installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.

Warning Only trained and qualified personnel should install or replace this equipment.

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI card when no cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Emissions Requirement.

Tools Required

You need a flat-blade screwdriver to remove any filler (blank) switching modules and to tighten the captive installation screws that secure the modules in their slots. Whenever you handle switching modules, you should use a wrist strap or other grounding device to prevent ESD damage. See the section "Preventing Electrostatic Discharge Damage."

Removing Switching Modules

To remove a switching module from a Catalyst 5000 series switch, perform the following steps:

Caution To prevent ESD damage, handle switching modules by the carrier edges only.

Step 1 If you do not plan to reinstall the switching module immediately after removing it, disconnect any network interface cables attached to the switching module ports.

Step 2 Use a flat-blade screwdriver to loosen the captive installation screws, shown in Figure 4.

Figure 4 Ejector Levers and Captive Installation Screws

Step 3 Place your thumbs on the left and right ejector levers and simultaneously push the levers outward to release the module from the backplane connector. Figure 4 shows a close-up of the right ejector lever.

Step 4 Grasp the switching-module handle with one hand and place your other hand under the carrier to support and guide it out of the slot. Avoid touching the module.

Step 5 Carefully pull the switching module straight out of the slot, keeping your other hand under the carrier to guide it. Keep the switching module oriented horizontally.

Step 6 Place the switching module on an antistatic mat or antistatic foam or immediately install it in another slot.

Step 7 If the slot is to remain empty, install a switching-module filler plate (part number 800-00292-01) to keep dust out of the chassis and to maintain proper airflow through the switching-module compartment.

Caution Always install the switching-module filler plate in empty switching module slots to maintain the proper flow of cooling air across the modules.

Installing Switching Modules

All Catalyst 5000 series switching modules are installed in horizontal slots that are numbered from top to bottom. Figure 5 shows an example of how slots are numbered on the chassis; in this case using the Catalyst 5000 switch. The slot numbering for the Catalyst 5002 switch and the Catalyst 5500 switch is similar to that shown in Figure 5.

Figure 5 Module Slot Numbers

To install a switching module in a Catalyst 5000 series switch, perform the following steps:

Caution To prevent ESD damage, handle switching modules by the carrier edges only.

Step 1 Make sure you have taken the necessary precautions to prevent ESD damage, as described in the section "Preventing Electrostatic Discharge Damage."

Step 2 Choose a slot for the new switching module. Ensure that there is enough clearance to accommodate any interface equipment that you will connect directly to the switching module ports. If possible, place switching modules between empty slots that contain only switching module filler plates.

Step 3 Use a flat-blade screwdriver to loosen the captive installation screws securing the switching-module filler plate (or the existing switching module) from the desired slot.

Step 4 Remove the switching-module filler plate (or the existing switching module).

Step 5 Hold the switching-module handle with one hand and place your other hand under the carrier to support the switching module and guide it into the slot. Avoid touching the printed circuit boards or connector pins.

Step 6 Place the switching module in the slot. Align the notch on the sides of the switching-module carrier with the groove in the slot, as shown in Figure 6 for the Catalyst 5000 switch. Use the same procedure for the Catalyst 5002 and Catalyst 5500 switches.

Figure 6 Module Installation

Step 7 Maintain the switching module at a 90-degree orientation to the backplane and carefully slide the switching module into the slot until the switching-module faceplate contacts the ejector levers.

Step 8 Use the thumb and forefinger of each hand and simultaneously push in the left and the right levers to seat the switching module in the backplane connector.

Caution Always use the ejector levers when installing or removing switching modules. A module that is partially seated in the backplane will cause the system to halt and subsequently crash.

Step 9 Use a flat-blade screwdriver to tighten the captive installation screws on the left and right ends of the switching module.

Step 10 Attach network interface cables or other devices to the interface ports.

Step 11 Check the status of the interfaces as follows:

If this installation is a replacement switching module, use the show module or show port [mod_num/port_num] command to verify that the system has acknowledged the new interfaces and brought them up.
If the interfaces are new, use the set module command and the set module name command to configure the new interface(s). This does not have to be done immediately, but the interfaces will not be available until you configure them. See the Catalyst 5000 Series Software Configuration Guide for information on how to configure new interfaces.

Configuring FDDI and CDDI Modules

This section lists the default configurations of the FDDI and CDDI switching modules and provides a basic summary of the commands used to customize the configuration of each module.

Default Configuration

The features you can customize have default values that will most likely suit your environment and need not be changed. The default values of these features are listed in Table 6.

Table 6 Feature Default Configuration Values

Feature	Default Setting
Port enable state	All FDDI and CDDI ports are enabled
IPX¹ protocol translation	FDDI SNAP² to Ethernet 802.3 RAW Ethernet 802.3 RAW to FDDI SNAP FDDI 802.2 to Ethernet 802.3
Module parameters	TL_MIN parameter is set to 40 microseconds TNotify parameter is set to 30 seconds TRequest parameter is set to 165,000 microseconds
User-data string³	Catalyst 5000
IP fragmentation	Enabled
ICMP⁴ unreachable messages	Enabled
LER⁵ settings	LER-Alarm is set to 8 (10^-8) LER-Cutoff is set to 7 (10^-7)

1IPX=Internetwork Packet Exchange

2SNAP=Subnetwork Access Protocol

3The user-data string is used to identify the FDDI module

4ICMP=Internet Control Message Protocol

5LER=link error rate

Customizing the Configuration

Table 7 lists the major features available on the FDDI and CDDI modules and the commands needed to configure them.

Task	Commands
Setting the Default IPX Protocol Translations
To set the FDDI SNAP¹ to Ethernet translation:
Step 1. Configure the appropriate translation protocol.	set bridge ipx snaptoether {8023 \| SNAP \| EII \| 8023RAW}
Step 2. Verify that the correct translation protocol was configured.	show bridge
To set the FDDI 802.2 to Ethernet translation:
Step 1. Configure the appropriate protocol translation.	set bridge ipx 8022toether {8023 \| SNAP \| EII \| 8023RAW}
Step 2. Verify that the correct protocol translation was configured.	show bridge
To set the FDDI 803.2 raw to FDDI protocol:
Step 1. Configure the appropriate protocol translation.	set bridge ipx 8023rawtofddi {8022 \| SNAP \| FDDIRAW}
Step 2. Verify that the correct translation protocol was configured.	show bridge
Setting the Minimum Time to Transfer the FDDI PHY Line State
Set TL_MIN to a value between 40 and 1,340,006 microseconds.	set fddi tlmin mod_num/port_num time
Setting the Interval between Neighbor Notification Frames
Set TNotify to a value between 2 and 30 seconds.	set fddi tnotify mod_num time
Setting the Timer for Negotiating Token Ring Timer
Set TRequest to a value between 2502 and 165,000 microseconds.	set fddi treq mod_num time
Specifying the User-Data String
Enter a module number and a unique description or name to identify the FDDI module.	set fddi userdata mod_num userdata_string
Disabling IP Fragmentation
Disable IP fragmentation.	set ip fragmentation disable
Disabling ICMP Unreachable Messages
Disable ICMP unreachable messages.	set ip unreachable disable
Setting the Link Error Rate Alarm
Change the LER-alarm setting.	set fddi alarm mod_num/port_num value
Setting the Link Error Rate Cutoff
Change the LER-cutoff setting.	set fddi cutoff mod_num/port_num value
Setting the Port Name
Configure a name for a port.	set port name mod_num/port_num [name_string]
Setting the Port Priority Level
Configure the priority level for each CDDI or FDDI port.	set port level mod_num/port_num {normal \| high}
Setting Up a Native VLAN on FDDI
Assign a VLAN to map to native traffic on an FDDI port.	set vlan vlan_num mod/ports
Setting Up an FDDI 802.10 Configuration
Step 1. Provide a VLAN number and activate a VLAN in the management domain.	set vlan vlan_num
Step 2. Create a VLAN with the type FDDI.	set vlan vlan_num type fddi
Step 3. Map the Ethernet VLAN translation to an FDDI VLAN.	set vlan ether_vlan_num translation fddi_vlan_num or set vlan fddi_vlan_num translation ether_vlan_num
Step 4. Turn the trunking on for the FDDI port.	set trunk mod_num/port_num on
Checking Connectivity
Step 1. Send an echo request from the Catalyst 5000 series switch to the host.	ping host
Step 2. If the host is unresponsive, check the configuration for the IP address of the Catalyst 5000 series switch and default IP route, if appropriate.	show interface show ip route

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Turn the television or radio antenna until the interference stops.
Move the equipment to one side or the other of the television or radio.
Move the equipment farther away from the television or radio.
Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems could void the FCC approval and negate your authority to operate the product.
