The Gigabit Ethernet uplink ports operate in full-duplex mode only. These ports use the 1000BASE-SX, 1000BASE-LX/LH, and 1000BASE-ZX Gigabit Interface Converters (GBICs). GBICs have SC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable. For more information on GBICs, see the "GBIC Handling Installation and Guidelines" section.
The Ethernet management port is used (in ROMMON mode only) to recover a switch software image that has been corrupted or destroyed due to a network catastrophe. This port is not active while the switch is operating normally.
The Catalyst 4000 family Supervisor Engine III console port has an EIA/TIA-232 RJ-45 connector. The console port allows you to perform the following functions:
The Reset button is used to restart the switch.
Note Use a paper clip or other small, pointed object to press the Reset button. |
The Flash port accepts a Type 1 compact Flash card. You can use it for file transfer tasks such as loading a new software image. The Flash card (MEM-C4K-FLD64M= or MEM-C4K-FLD128M=) is optional.
For more information, refer to Using the Compact Flash on the Catalyst 4000 Family Supervisor Engine III and IV at the following URL:

This section provides port cabling specifications and includes the following subsections:
The length of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission medium (the type of cabling used to transmit the signals). The distance and rate limits specified in this document are the IEEE-recommended maximum speeds and distances for signaling. Table 2 shows the transmission speed and the distance.
Table 2 EIA/TIA-232 Transmission Speed in Contrast with Distance
|
Table 3 shows the maximum cable distances for transceiver speed and cable type.
Table 3 Maximum Cable Distances
|
Table 4 provides cabling specifications for the GBICs that you install in the Gigabit Ethernet port modules. All GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs listed is 6.5 feet (2 meters).
Table 4 GBIC Port Cabling Specifications
|
1 MMF only. 2 Patch cord required (see the "Using a Patch Cord" section for details). 3 Dispersion-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 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 meters) and must 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 1000BASE-LX. For more information, refer to the Catalyst 4000 Series Installation Guide and Catalyst 4500 Series 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 4000 Series Installation Guide and Catalyst 4500 Series Installation Guide. All equivalent cables should also meet the standards specified in the guide.
All Catalyst 4000 family switches support hot swapping, which lets you install, remove, replace, and rearrange supervisor engines and switching modules without power ing the system off. 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.
This section contains the following subsections:
You will need these tools to install a supervisor engine in a Catalyst 4000 family switch:
Note Whenever you handle supervisor engines, use a wrist strap or other grounding device to prevent ESD damage. |
Catalyst 4000 family switches have horizontal chassis slots that are numbered from top to bottom. You can install the Catalyst 4000 family supervisor engine in slot 1 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. |
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only. |
To install a supervisor engine in a Catalyst 4000 family switch, follow this procedure:
Step 2 Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the supervisor engine ports.
Step 3 Loosen the captive installation screws that secure the switching-module filler plate or the existing supervisor engine (whichever is present) and remove it.
Step 4 Remove the supervisor engine filler plate or the existing supervisor engine from slot 1. If a switching module filler plate was installed, save it for future use. If you are removing an existing supervisor engine, see the "Removing the Supervisor Engine" section.
Step 5 To install the new supervisor engine, grasp the switching module front panel with one hand and place your other hand under the carrier to support the supervisor engine, as shown in Figure 2. Do not touch the printed circuit boards or connector pins.
Step 6 Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis, as shown in Figure 2.
Step 7 Pivot the two module ejector levers out and away from the faceplate.
Step 8 Carefully slide the supervisor engine into slot 1 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 supervisor engine in the backplane connector.
Caution Always use the ejector levers when installing or removing a supervisor engine. A supervisor engine that is partially seated in the backplane will not function correctly. |
Step 10 Use a screwdriver to tighten the captive installation screws on each end of the supervisor engine faceplate.
You have now completed the installation procedure.
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.
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. |
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. |
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only. |
To remove a supervisor engine from a Catalyst 4000 family switch, follow this procedure:
Step 2 Loosen the captive installation screws (see Figure 3).
Step 3 Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the supervisor engine from the backplane connector. Figure 3 shows a close-up of the right ejector lever.
Step 4 Grasp the front panel of the supervisor engine 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 supervisor engine straight out of the slot, keeping your other hand under the carrier to guide it.
Step 6 Place the supervisor engine on an antistatic mat or antistatic foam, or immediately install it in another slot.
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. |
Step 7 If the slot is to remain empty, install a switching-module filler plate (part number 800-00292-01).
Figure 4 and Figure 5 show the connector types used to attach interface cables to the supervisor engine.
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. |
For information and commands to configure your supervisor engine, refer to the software configuration guide for your switch.
A GBIC (see Figure 6) is a hot swappable input/output device that plugs into the Gigabit Ethernet port of a supervisor engine and links the supervisor engine with a fiber-optic network. GBICs are online swappable.
The following GBIC media types are supported:
Caution Because of interoperability issues, Cisco does not support GBICs purchased from third-party vendors. |
Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 10 km over SMF cable instead of the 5 km specified in the standard.
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 4000 Family Module Installation Guide for more information.
This section describes the following topics:
A supervisor engine 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 can 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 acceptable-safety-emission limits for Class 1 lasers. However, you should still take general precautions when working with lasers. |
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. |
To install a GBIC, follow this procedure:
Step 2 Verify that the GBIC is the correct type for your network by checking the GBIC part number. The part number indicates whether it is 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX.
Step 3 Grasp the sides of the GBIC with your thumb and forefinger; insert the GBIC into the appropriate slot on the front of the module (see Figure 7).
Note GBICs are keyed to prevent incorrect insertion into a slot. |
Step 4 Slide the GBIC into the slot until you hear a click. The click indicates that the GBIC is locked into the slot.
Step 5 When you are ready to attach the fiber-optic cable, remove the plug from the GBIC and save it 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 on the fiber-optic cable (see Figure 5 on). Insert the connector into the GBIC.
You have now completed the installation procedure.
Note When you plug the SC-type connector into the GBIC, ensure that you fully insert the Tx and Rx fiber-optic cables 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 a Patch Cord" section on for details. |
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. |
To remove a GBIC, follow this procedure:
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 two plugs into the GBIC optical bores, and place the GBIC in its protective packaging.
You have now completed the removal procedure.
To properly maintain GBICs, follow these guidelines:
