This section describes the supervisor engines available for the Catalyst 4003 and 4006 switches.
The WS-X4012 supervisor engine (see Figure 1) is used in the Catalyst 4003 switch. The supervisor engine provides data path and data control for all network interfaces.
The supervisor engine is hot swappable, but packets are not forwarded while the supervisor engine is being removed. A system reboot occurs when a supervisor engine is reinserted.
The supervisor engine provides management functions such as monitoring the interface and the environmental status and providing the Simple Network Management Protocol (SNMP) and console and Telnet interface.
The WS-X4013 supervisor engine (see Figure 2) is used in the Catalyst 4006 switch.
This section describes the LEDs, connectors, and switches on the WS-X4012 and WS-X4013 supervisor engines.
Table 1 describes the LEDs on the supervisor engine front panel.

The same TCP/IP-based management services that are available through the in-band access are also available through the Ethernet management port (Telnet and SNMP). The Ethernet management port also supports image download.
The following Ethernet management ports are provided on the supervisor engines:
Both ports use an RJ-45 connector on the front panel with a link status LED.
|
Note The 10BaseT and 10/100BaseT Ethernet management ports are used for network management only. These ports do not support network switching. |
The console port allows you to perform the following functions:
The following console ports are provided on the supervisor engines:
|
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA). |
The Gigabit Ethernet uplink ports operate in full-duplex mode only. These ports use the 1000BaseSX, 1000BaseLX/LH, and 1000BaseZX GBICs. GBICs have SC connectors to interface with multimode fiber-optic (MMF) and single-mode fiber-optic (SMF) cable. For further information on GBICs, see the "GBIC Handling Guidelines and Installation" section.
The Reset button is used to restart the switch.

A GBIC (see Figure 14) is a hot-swappable input/output device that plugs into the Gigabit Ethernet port of the module, which links the module with the fiber-optic network. GBICs are online swappable.
The following GBIC media types are supported:
Other GBIC media types may be supported as additional technology becomes available.
Cisco 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus 5 km specified in the standard.
|
Note Because of interoperability issues, Cisco does not support GBICs purchased from third-party vendors. |
If an LX/LH GBIC designed for operation on an SMF cable is directly coupled to an MMF cable, an effect known as Differential Mode Delay (DMD) might occur. See the Catalyst 4003 and 4006 Switch Installation Guide for more information.
This section describes the following topics:
A switching module can be shipped with or without GBICs installed.
 |
Caution When removing or inserting a GBIC, always wear an ESD wrist strap connected to the ESD wrist strap connector. |
|
Caution Unnecessary removal or insertion of a GBIC could lead to premature failure of the GBIC. A GBIC has a lifetime of 100 to 500 removals and insertions. |
|
Note This product has been evaluated to, and complies with, Class 1 lasers acceptable-safety- emission limits. However, you should take general precautions, when working with lasers. |
 |
Warning Invisible laser radiation may be emitted from the aperture ports of fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures. |
To install a GBIC, perform these steps:
Step 2 Verify that the GBIC is the correct type for your network by checking the part number. The part number indicates whether it is 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX.
Step 3 Grip the sides of the GBIC with your thumb and forefinger; insert the GBIC into the slot on the front of the module (see Figure 15).
|
Note GBICs are keyed to prevent incorrect slot insertion. |
Step 4 Slide the GBIC into the slot until you hear a click. The click indicates the GBIC is locked into the slot.
Step 5 When you are ready to attach the fiber-optic cable, remove the plugs from the GBIC and save them for future use.
|
Caution Do not remove the plugs from the GBIC optical bores or the fiber-optic cable until you are ready to connect the cable. The plugs protect the GBIC optical bores and cable from contamination. |
Step 6 Remove the plugs from the SC-type connector (see Figure 22 on) on the fiber-optic cable. Insert the connector into the GBIC.
|
Note When you plug the SC-type connector into the GBIC, make sure that both the Tx and Rx fiber-optic cables are fully inserted into the SC-type connector. |
|
Note If you are using the LX/LH GBIC with MMF, you need to install a patch cord between the GBIC and the MMF cable. See the "Using the Patch Cord" section for details. |
To remove a GBIC, perform these steps:
|
Note If you are removing the GBIC from an online switch, enter the show port command to verify the type of GBIC that is installed. |
Step 2 Release the GBIC from the slot by simultaneously squeezing the plastic tabs (one on each side of the GBIC).
Step 3 Slide the GBIC out of the slot.
Step 4 Install the plugs in the GBIC optical bores, and place the GBIC in protective packaging.
To properly maintain GBICs, follow these guidelines:
The length of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). The distance and rate limits in this chapter are the IEEE-recommended maximum speeds and distances for signaling. The transmission speed versus distance is shown in Table 2.
| Rate (bps) | Distance (feet) | Distance (meters) |
|---|---|---|
2400 | 200 | 60 |
4800 | 100 | 30 |
9600 | 50 | 15 |
19,200 | 25 | 7.6 |
38,400 | 12 | 3.7 |
56,000 | 8.6 | 2.6 |
This section describes the following topics:
Table 3 shows the maximum cable distances for transceiver speed and cable type.
| Transceiver Speed | Cable Type | Duplex Mode | Maximum Distance Between Stations |

| 1MMF only. 2Patch cord required (see the "Using the Patch Cord" section for details). 3Dispersion-shifted single-mode fiber-optic. |
When using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord (Cisco product no. 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 meters). The 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 patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BaseLX. For a detailed description of this problem, refer to the Catalyst 4003 and 4006 Installation Guide.
|
Note We do not recommend using the LX/LH GBIC with MMF without a patch cord for very short link distances (tens of meters). The result could be an elevated bit error rate (BER). |
Cisco Gigabit Ethernet products have been tested and evaluated to comply with the standards listed in Appendix A, "Specifications" of the Catalyst 4003 and 4006 Installation Guide. All equivalent cables should also meet these standards.
Safety warnings appear throughout this note in procedures that may harm you if performed incorrectly. A warning symbol precedes each warning statement.
|
Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translations of the warnings that appear in this publication, refer to the "Translated Safety Warnings" section.) |
|
Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. |
All Catalyst 4003 and 4006 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 runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.
|
Warning Only trained and qualified personnel should install, replace, or service this equipment. |
|
Warning Invisible laser radiation can be emitted from the aperture ports of the single-mode products when no fiber-optic cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Laser Emission Requirement. |
This section describes the following topics:
These tools are required to install supervisor engines and switching modules in the Catalyst 4003 and 4006 switches:
|
Note Whenever you handle switching modules, you should use a wrist strap or other grounding device to prevent ESD damage. |
|
Caution To prevent ESD damage, handle switching modules by the carrier edges only. |
|
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. |
To remove a switching module from a Catalyst 4003 or 4006 switch, perform these steps:
Step 2 Loosen the captive installation screws, as shown in Figure 16.
Step 3 Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the switching module from the backplane connector. Figure 16 shows a close-up of the right ejector lever.
Step 4 Grasp the switching-module front panel with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 5 Carefully pull the switching module straight out of the slot, keeping your other hand under the carrier to guide it.
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).
|
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. |
All Catalyst 4003 and 4006 supervisor engine modules and switching modules are installed in horizontal chassis slots that are numbered from top to bottom.
|
Caution To prevent ESD damage, handle switching modules by the carrier edges only. |
|
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. |
To install a switching module in a Catalyst 4003 or 4006 switch, perform these steps:
Step 2 Choose a slot for the new switching module. Ensure you have 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 Loosen the captive installation screws securing the switching-module filler plate (or the existing switching module) to the desired slot.
Step 4 Remove the switching-module filler plate (or the existing switching module). Save the switching-module filler plate for future use. If you are removing an existing switching module, see the "Removing Switching Modules" section.
Step 5 To install the new switching module, hold the switching-module front panel with one hand, and place your other hand under the carrier to support the switching module, as shown in Figure 17. Do not touch the printed circuit boards or connector pins.
Step 6 Align the edges of the switching module carrier with the slot guides on the sides of the switch chassis, as shown in Figure 17.
Step 7 Pivot the two module ejector levers out away from the faceplate.
Step 8 Carefully slide the switching module into the slot until the notches on both ejector levers engage the chassis sides.
Step 9 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers to fully 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 reset. |
Step 10 Use a screwdriver to tighten the captive installation screws on each end of the switching module faceplate.
To check the status of the module, perform these steps:
Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the new module and that the module's status is good.
Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer service representative.
This section describes how to replace and install uplink modules.
|
Caution When removing or inserting a module, always wear an ESD wrist strap connected to the ESD wrist strap connector or to a connection that is properly grounded. |
To remove and replace an uplink module, follow these steps:
Step 2 Place the switching module on an antistatic work surface.
Step 3 Use a Phillips-head screwdriver to remove the four screws securing the uplink module to the switching module. (See Figure 18.)
Step 4 Carefully pull the uplink module up and out of the switching module.
|
Note The rear of the uplink module connects to the switching module through connectors on the bottom side of the uplink module. Use care when unseating the uplink module from these connectors. |
Step 5 Place the removed uplink module in an antistatic bag.
Step 6 Remove the new uplink module from its antistatic bag and install it in the switching module. Use care when seating the rear of the uplink module into the connectors.
Step 7 Ensure that the uplink module is securely seated in the switching module.
|
Caution Ensure that the module is securely seated before installing and tightening the securing screws. Using the screws to seat the module could warp the module. |
Step 8 Use a Phillips-head screwdriver to install the four screws that secure the uplink module to the switching module (see Figure 18).
Step 9 Install the switching module into the Catalyst 4003 or 4006 switch. See the "Installing Switching Modules" section for more information.
To add an uplink module to a switching module with no uplink module, follow these steps:
Step 2 Use a Phillips-head screwdriver to remove the two screws securing the blank uplink module filler plate from the switching module. Set the screws in a secure place because they will be reused.
Step 3 Use a Phillips-head screwdriver to remove the two screws from the two standoffs that will secure the rear of the uplink module. Set the screws in a secure place because they will be reused.
Step 4 Remove the new uplink module from its antistatic bag and install it in the switching module. Use care when seating the rear of the uplink module into the connectors.
Step 5 Ensure that the uplink module is securely seated in the switching module.
Step 6 Use a Phillips-head screwdriver to install the four screws that secure the uplink module to the switching module. (See Figure 18.)
|
Caution Ensure that the module is securely seated before installing and tightening the securing screws. Using the screws to seat the module could warp the module. |
Step 7 Install the module into the Catalyst 4003 or 4006 switch (see the "Installing Switching Modules" section).
Figure 19 through Figure 23 show the connector types used to attach interface cables to the supervisor engine and switching modules.
|
Note Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use. |
|
Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. |
When you are connecting MT-RJ cables to a module, make sure you firmly press the connector plug into the socket. The upper edge of the plug must snap into the upper front edge of the socket. You may or may not hear an audible click. Gently pull on the plug to confirm whether or not the plug is locked into the socket.
To disconnect the plug from the socket, press down on the raised portion on top of the plug (releasing the latch). You should hear an audible click indicating the latch has released. Carefully pull the plug out of the socket.
|
Note When you disconnect the fiber-optic cable from the module, grip the body of the connector. Do not grip the connector jacket-sleeve. Gripping the sleeve can, over time, compromise the integrity of the fiber-optic cable termination in the MT-RJ connector. |
Always make sure that you insert the connector completely into the socket. This is especially important when you are making a connection between a module and a long distance (2 km) or a suspected highly attenuated network.
If the link LED does not light, try removing the network cable plug and reinserting it firmly into the module socket. It also is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings) which can generate significant attenuation, reducing the optical power levels below threshold levels so that a link cannot be made.
To clean the MT-RJ plug faceplate:
Step 2 Carefully wipe the faceplate with a dry lint-free tissue.
Step 3 Remove any residual dust from the faceplate with compressed air before installing the cable.
|
Note Make sure that dust caps are installed on all unused module connectors and unused network fiber-optic cable connectors. |
Some of the Gigabit Ethernet ports on Gigabit Ethernet switching modules WS-X4418-GB and WS-X4412-2GB-T are oversubscribed. An oversubscribed port may have a limit on the amount of data the port can receive without dropping packets.
The WS-X4418-GB Gigabit Ethernet switching module offers two dedicated 1000BaseX (GBIC) ports (Ports 1 and 2) and 16 oversubscribed (possibly blocking) 1000BaseX (GBIC) Gigabit Ethernet ports. The module provides a Gigabit Ethernet network backbone connection for multiple servers or high-end workstations.
Ports 1 and 2 each have 1-Gbps dedicated bandwidth. These ports are typically used to connect to the network backbone.
The 16 oversubscribed ports (ports 3 through 18) are multiplexed in four groups of four ports each:
To help identify the groups, lines on the front panel of the WS-X4418-GB are used to frame the port groups.
Each group of four ports shares 1-Gbps of bandwidth.
The oversubscribed Gigabit ports are typically used to connect to clients or servers equipped with Gigabit Ethernet NICs.
The WS-X4412-2GB-T Gigabit Ethernet switching module offers two dedicated 1000BaseX (GBIC) ports (ports 13 and 14) and 12 oversubscribed (possibly blocking) 1000BaseTX Gigabit Ethernet ports. The module provides a Gigabit Ethernet network backbone connection for multiple servers or high-end workstations.
Ports 13 and 14 each have 1-Gbps dedicated bandwidth. These ports are typically used to connect to the network backbone.
The 12 oversubscribed ports (ports 1 through 12) are multiplexed in three groups of four ports each:
The four ports within each group use common circuitry that effectively multiplexes the group into a single, nonblocking, full-duplex Gigabit connection to the internal switch fabric. For each group of four ports, received frames are buffered and sent to the common Gigabit link to the internal switch fabric. If the amount of received data for a port begins to exceed the buffer capacity, flow control (pause frames) are sent to the port's linked device to temporarily stop traffic and prevent frame loss.
|
Note If only one port within a group is connected, flow control may be disabled on that port. |
When transmitting, each port in the group shares the bandwidth of a Gigabit link. However, each port operates independently so that flow control, or configuration of one port, does not block or degrade the performance of another port in that group.
When configuring a network you should use the dedicated 1-Gbps bandwidth ports where nonblocking performance without flow control is needed, such as a connection to another internetworking device.
When the Gigabit Ethernet switching module is not fully utilized, you can connect balancing port connections across port groupings to maximize available bandwidth. For example, with the WS-X4418-GB Gigabit Ethernet switching module, connect ports from different groups, such as
ports 3, 4, 11, or 12 (in any order) before you connect ports from the same group, ports 3 and 5, or ports 4, 6, and 8.
When configuring oversubscribed ports, follow these guidelines:
set port flowcontrol {send | receive} [mod_num/port_(3to18)] {on |off | desired}
For more information about flow control or autonegotiation, refer to the Software Configuration Guide for your switch.
For information and commands to configure your supervisor engine module or switching module, refer to the Software Configuration Guide for your switch.
For more detailed installation and configuration information, refer to the following:
