Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Preventing ESD Damage
ESD damage occurs when electronic modules or components are improperly handled and can result in complete or intermittent failures. To prevent ESD damage, follow these guidelines:
- Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
- When handling modules or coming into contact with any internal components, always use a wrist strap connected to one of the following:
- Captive installation screws on an installed module or power supply
- ESD wrist strap connector
- Any unpainted surface on the chassis
- Handle modules by the edges only.
- Avoid contact between the modules and clothing. The wrist strap protects only the module from ESD voltages on the body; ESD voltages on clothing can still cause damage.
- After removing a supervisor engine, place it 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.
Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).
Removing and Replacing the Supervisor Engine
Note To support supervisor engine redundant operation, both the supervisor engines must be
Supervisor Engine III Gs.
Note Catalyst 5505, Catalyst 5509, and Catalyst 5500 switches—When two supervisor engines
are installed, hot swapping allows you to remove and replace one of the supervisor engines without
turning off the system power.
Avoiding Problems When Inserting and Removing Modules
The ejector levers on the supervisor engine align and seat the supervisor engine connectors in the backplane. (See Figure 3.) If you fail to use the ejector levers to insert the supervisor engine, you can disrupt the order in which the pins make contact with the backplane. When removing a supervisor engine, use the ejector levers to ensure that the supervisor engine connector pins disconnect from the backplane properly. Any supervisor engine or switching supervisor engine that is only partially connected to the backplane can disrupt the system.
Figure 3 Ejector Levers and Captive Installation Screws
Removing the Supervisor Engine
Before you remove a supervisor engine, you should first upload the current configuration to a server. This saves time when bringing the supervisor engine back online. Enter the write network command to upload the configuration file to the network. Enter the copy command to download the current configuration to a Flash memory device on the new supervisor engine.
To remove the supervisor engine from the switch, follow these steps:
To prevent ESD damage, handle switching modules by the carrier edges only.
When removing or inserting a switching module, always wear an ESD wrist strap connected to the Catalyst 5000 series switch ESD wrist strap connector.
Step 1 Take the necessary precautions to prevent ESD damage, as described in the "Preventing ESD Damage" section.
Step 2 If you do not plan to immediately reinstall the supervisor engine you are removing, disconnect any network interface cables attached to the module ports.
Step 3 Use a screwdriver to loosen the captive installation screws at the left and right sides of the module.
Step 4 Grasp the left and right ejector levers. Simultaneously pull the left lever to the left and the right lever to the right to release the module from the backplane connector.
Step 5 Grasp the handle of the module with one hand and place your other hand under the carrier to support and guide the module out of the slot. Avoid touching the module itself.
Step 6 Carefully pull the module straight out of the slot, keeping your other hand under the carrier to guide it. Keep the module at a 90-degree orientation to the backplane.
Step 7 Place the removed supervisor engine on an antistatic mat, foam, or bag.
Step 8 If the slot is to remain empty, install a module filler plate to keep dust out of the chassis and to maintain proper airflow through the module compartment.
Always install a switching module filler plate in empty switching module slots to maintain the proper flow of cooling air across the modules.
Note When you remove and replace the supervisor engine, the system provides status messages on
the console screen. The messages are for information only. Enter the show system and show module
commands to view specific information. For additional information, refer to the Catalyst 5000 Series
Software Configuration Guide and the Catalyst 5000 Series Command Reference publication.
Installing the Supervisor Engine
When installing the supervisor engine, note that it must go in a specific slot:
- Catalyst 5000—slot 1
- Catalyst 5505, 5509, and Catalyst 5500—slot 1 (if a second, redundant supervisor is installed, it goes in slot 2)
- Catalyst 5002—slot 1
To install the supervisor engine, follow these steps:
To prevent ESD damage, handle switching modules by the carrier edges only.
When removing or inserting a switching module, always wear an ESD wrist strap connected to the Catalyst 5000 series switch ESD wrist strap connector.
Step 1 Take the necessary precautions to prevent ESD damage, as described in the "Preventing ESD Damage" section.
Step 2 To install the supervisor engine, hold the front panel with one hand, and place your other hand under the carrier to support the supervisor engine. Do not touch the printed circuit boards or connector pins.
Step 3 Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis.
Step 4 Pivot the two module ejector levers out away from the faceplate. The ejector levers are shown pivoted out in Figure 4.
Figure 4 Module Ejector Lever Operation
Step 5 Keeping one hand under the carrier to guide the supervisor engine, carefully slide it into the slot on the Catalyst 5000 series switch until the ejector levers click into place on the chassis. Be sure to keep the module horizontal to the backplane and avoid touching any of the components on the module.
Step 6 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers, as shown in Figure 4, to fully seat the switching module in the backplane connector.
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 7 Use a screwdriver to tighten the captive installation screws at the left and right sides of the module.
Connecting a Terminal to the Console Port
Connect the terminal using a thin, flat, RJ-45-to-RJ-45 cable (looks like a telephone cable) and an RJ-45-to-DB-9, RJ-45-to-D-subminiature female, or RJ-45-to-D-subminiature male adapter.
Note An RJ-45-to-RJ-45 cable and adapters are provided in the console port accessory kit shipped
with your Supervisor Engine III.
See the next section, "Configuring a Terminal for Attachment to the Console Port," for port configuration details. Table 2 lists the pinouts for the console port.

Configuring a Terminal for Attachment to the Console Port
Note The console port is an asynchronous serial port; any device connected to this port must be
capable of asynchronous transmission.
Before connecting the console port, check the terminal documentation to determine the baud rate. The baud rate of the terminal must match the default baud rate (9600 baud) of the console port. Set up the terminal as follows:
- 9600 baud
- 8 data bits
- No parity
- 1 stop bit
Connecting to the Interface Ports
The Supervisor Engine III G has two GBICs with 1000BaseSX MMF connectors, 1000BaseLX/LH MMF and SMF connectors, or 1000BaseZX connectors (see Figure 5).
The 1000BaseSX MMF, 1000Base LX/LH MMF and SMF, and 1000BaseZX ports operate in full-duplex mode only.
For information on interface cables and equipment, such as Ethernet transceivers, refer to the Catalyst 5000 Series Supervisor Engine Installation Guide.
1000BaseSX, 1000BaseLX/LH, and 1000BaseZX (Single-Mode or Multimode Fiber-Optic Connectors)
Use SC fiber-optic connectors (see Figure 5) to connect to the 1000BaseSX, 1000BaseLX/LH, and 1000BaseZX ports. Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use.
Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.
Figure 5 SC Fiber-Optic Connector Type
Connecting Gigabit Ethernet Modules
Supervisor Engine III G has Gigabit Ethernet ports that you can configure with any combination of GBICs. A GBIC, shown in Figure 6, is a hot-swappable input/output device that plugs into the module, linking the module with the fiber-optic network. GBIC types are listed in Table 4.

Note Cisco 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX standard.
However, the 1000BaseLX/LH has a higher optical quality, allowing link distances of 10 km over
SMF versus the 5 km specified in the standard.
Note A maximum of 12 1000BaseZX GBICs can be installed in a switch chassis.
The GBIC slides through an opening in the front of the Gigabit Ethernet module and mates with a connector on the module. (See Figure 7.)
Figure 7 Installing a GBIC (WS-X5403 shown)
Use a SC-type single-mode (fiber) connector, shown in Figure 5, to connect the Gigabit Ethernet module ports with the external network. Connect the Gigabit Ethernet interface cables to the appropriate Ethernet network connector.
When using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord (Cisco product number CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link. The patch cord is required for link distances greater than 984 feet (300 m). Refer to the Catalyst 5000 Series Supervisor Engine Installation Guide for more information on patch cords.
Note The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE
found that link distances could not be met with certain types of fiber-optic cable due to a problem in
the center of some fiber-optic cable cores. The solution is to launch light from the laser at a precise
offset from the center by using the mode-conditioning patch cord. At the output of the patch cord,
the LX/LH GBIC is compliant with IEEE 802.3z standard for 1000BaseLX.
Verifying System Operation
When all interfaces are connected, check all connections, and then follow these steps to verify that the switch is operational:
Step 1 Check the console terminal and make sure it is on.
Step 2 Verify that the appropriate PS1 and PS2 LEDs on the supervisor engine front panel are green.
Step 3 While the system initializes, check that the SYSTEM STATUS LED on the supervisor engine is orange until the boot is complete.
Step 4 Some interface LEDs might go on or blink for a short time. Some LEDs, such as the Link LED, stay on during the entire boot process. If an interface is already configured, the LEDs might be on steadily as they detect traffic on the line. Wait until the system boot is complete before attempting to verify the switching module LED indications.
Note Catalyst 5505, Catalyst 5509, and Catalyst 5500—If you have a redundant
supervisor engine, refer to the Catalyst 5000 Series Installation Guide for a detailed
description of supervisor engine operation in a redundant configuration. By default, the
supervisor engine in slot 1 is the active supervisor; the second supervisor in slot 2 is the
standby supervisor.
Note Many of the switching module LEDs are not on until you configure the interfaces.
Step 5 When the system boot is complete (it takes a few seconds), the supervisor engine begins to initialize the switching modules.
During this initialization, the LEDs on each switching module behave differently (most flash on and off). The Status LED on each switching module goes on when initialization is complete, and the console screen displays a script and system banner.
Note When switching module LEDs are on, this does not necessarily mean that the
interface ports are functional or enabled. Although the LEDs for many interface types go
on at the initial system startup, they do not indicate an accurate status until the interface
is configured. For detailed module-specific LED descriptions, refer to the Catalyst 5000
Series Module Installation Guide.
Note Catalyst 5500 only—The ATM system processor (ASP), ATM port adapter
carrier, and ATM adapter module LEDs are described in the LightStream 1010 ATM
Switch Hardware Installation Guide. The Catalyst 8510 Campus Switch Router (CSR)
Switch Route Processor (SRP) is described in the Catalyst 8510 Campus Switch Router
documentation. These publications are available on the Cisco Connection Documentation
CD and in print.
Note If the system does not complete this verification process, refer to Chapter 6,
"Troubleshooting the Installation," in the Catalyst 5000 Series Installation Guide for
troubleshooting procedures.
Step 6 Your hardware installation is now complete. Refer to the Software Configuration Guide and Command Reference publication for your switch for complete software configuration instructions.
