This chapter describes how to install and configure switching modules in your Catalyst 5000 series switch and is divided into the following sections:
Before installing switch modules, you must install the Catalyst 5000 series switch chassis and supervisor engine module(s). For information on installing the switch chassis and supervisor engine module(s), refer to the Catalyst 5000 Series Installation Guide.
 Caution
| Before installing switching modules, make sure you have read and understand all site preparation and safety requirements associated with your switch (see Chapter 2, "Installation Preparation" and the Catalyst 5000 Series Installation Guide). |
These tools are required to install switching modules in the Catalyst 5000 series switches:
Whenever you handle switching modules, always use a wrist strap or other grounding device to prevent electrostatic discharge (ESD). For information on preventing ESD, see the "Preventing Electrostatic Discharge Damage" section in Chapter 2, "Installation Preparation."
This section describes how to install switching modules in Catalyst 5000 series switches.
 Warning
| Only trained and qualified personnel should be allowed to install or replace this equipment. |
All Catalyst 5000 series switching modules are installed in horizontal slots that are numbered from top to bottom. Figure 3-1 shows the slots on the Catalyst 5000 switch chassis.
The Catalyst 5002 switch chassis has two slots. Slot 1 is reserved for the supervisor engine module. Slot 2 can contain any type of Catalyst 5000 series switching module.
The Catalyst 5000 switch chassis has five slots. Slot 1 is reserved for the supervisor engine module, which provides Layer 2 switching, local and remote management, and dual Fast Ethernet interfaces. You can use the remaining four slots for any combination of switching modules and RSMs.
The Catalyst 5505 switch chassis has five slots also. Slot 1 is reserved for the supervisor engine module, and slot 2 can contain a redundant Supervisor Engine III module, a switching module, or an RSM. The remaining three slots are used for any combination of switching modules and RSMs.
The Catalyst 5500 switch chassis has 13 slots, which can be populated as follows:
Switching-module filler plates, which are blank switching-module carriers, are installed in empty slots to maintain consistent airflow through the switch chassis.
To install switching modules in Catalyst 5000 series switches, perform these steps:
| Caution
| To prevent ESD damage, handle switching modules by the carrier edges only. |
Step 1 Make sure you take the necessary precautions to prevent ESD damage, as described in the section "Preventing Electrostatic Discharge Damage," in Chapter 2, "Installation Preparation."
Step 2 Choose a slot for the new switching module. Check 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. Do not touch 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 3-2 for the Catalyst 5000 switch. Use the same procedure for the Catalyst 5002 and Catalyst 5500 switches.
Step 7 Keep 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. See Figure 3-3.
Use the thumb and forefinger of each hand and simultaneously push in the left and right 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 subsequently crash. |
Use a screwdriver to tighten the captive installation screws on the left and right ends of the switching module.
| Warning
| Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures. |
Step 10 Attach network interface cables or other devices to the interface ports.
To remove a switching module from a Catalyst 5000 series switch, perform these steps:
Step 1 If you do not plan to reinstall the switching module immediately after removing it, disconnect any network interface cables attached to the module ports.
Step 2 Loosen the captive screws on the switching module using a flat-blade screwdriver.
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.
Step 4 Grasp the switching-module handle with one hand and place your other hand under the module to support and guide it out of the slot. Do not touch the module.
Step 5 Carefully pull the switching module straight out of the slot, keeping your other hand under the module to guide it. Keep the switching module oriented horizontally.
Step 6 Place the switching module on an antistatic mat or antistatic foam, or immediately reinstall it in another slot.
If the slot is to remain empty, install a switching-module filler plate to keep dust out of the chassis and to maintain proper airflow through the chassis.
| Caution
| Always install the switching-module filler plate in empty module slots to maintain the proper flow of cool air across the modules. |
On each 10BaseT, 100BaseTX, or 10/100BaseTX switching-module port, attach the cable connector and secure the cable in the port. For the 90-degree connector, use a tie wrap to provide strain relief. Most Ethernet connections do not require a transceiver on the interface cable. However, 100BaseTX Fast Ethernet connections to the media-independent interface (MII) connector on the supervisor engine module require a Fast Ethernet transceiver.
To secure the 10BaseT Ethernet switching module, tighten the screws and secure the Ethernet RJ-21 telco interface 90-degree connector with a tie wrap, as shown in Figure 3-4 and Figure 3-5.
To secure the group switching Ethernet module's 180-degree cable connection, engage the connector fully and tighten the two screws on either side of the connector, as shown in Figure 3-6 and Figure 3-7.
You can equip the Gigabit Ethernet module with either long- or short-wavelength-laser Gigabit Interface Converters (GBICs). The GBIC slides through an opening on the front of the module and mates with a connector on the card.
You can configure the Gigabit Ethernet module with any combination of long- and short- wavelength GBICs. Both GBIC types, single-mode fiber (SMF) or multimode fiber (MMF), use a single-mode (SC type) connector, shown in Figure 3-8, to connect the Gigabit Ethernet module with the external network. Connect the Gigabit Ethernet interface cables to the appropriate Ethernet network connector.
| Warning
| Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures. |
This section describes how to connect Copper Distributed Data Interface (CDDI) and Fiber Distributed Data Interface (FDDI) cables to their respective switching modules.
The unshielded twisted-pair (UTP) and fiber-optic cables connect directly to the CDDI or FDDI module ports. CDDI and FDDI modules use one integrated transmit/receive cable for each physical interface (one for PHY A and one for PHY B). You need one CDDI or FDDI cable for a single-attachment connection and two cables for a dual-attachment connection. For cable and connector descriptions, see Chapter 2, "Installation Preparation."
This section also provides instructions for connecting an optical bypass switch to a dual-attachment FDDI network connection. Because the method of connecting optical bypass switches varies with different manufacturers' models, refer to the documentation for your particular bypass switch for correct connection instructions. If you are installing an optical bypass switch, read the section "Installing an Optical Bypass Switch," later in this chapter.
The CDDI and FDDI modules that are connected as a single-attachment station (SAS) connect to the ring through a concentrator. The CDDI and FDDI modules receive and transmit the signal through the same physical interface, usually PHY A. Depending on whether you are connecting to a CDDI network or to a single-mode or multimode FDDI fiber network, connect the CDDI or FDDI modules as follows:
| Warning
| Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures. |
If you are connecting other CDDI or FDDI modules as dual-attachment stations (DASs), read the section "Making Dual-Attachment Connections."
CDDI and FDDI modules that are connected as DASs connect to both the primary and secondary rings. The signal for each ring is received on one physical interface (PHY A or PHY B) and transmitted from the other. The standard connection scheme (see Figure 3-11 and Figure 3-12) for a DAS dictates that the primary ring signal comes into the CDDI or FDDI module on the PHY A receive port and returns to the primary ring from the PHY B transmit port. The secondary ring signal comes into the CDDI or FDDI module on the PHY B receive port and returns to the secondary ring from the PHY A transmit port.
| Caution
| If you fail to observe this relationship, your CDDI or FDDI interface might not initialize. |
Each integrated transmit/receive multimode interface cable attaches to both the primary and secondary ring; each receives the signal from one ring and transmits to the other ring. To avoid confusion, use the receive label on the cable connector as a key and connect the cables to the CDDI/FDDI module ports as described above.
Figure 3-11 shows the FDDI dual-attachment connections for both MMF and SMF using MICs and straight-tip (ST) connectors. Figure 3-12 shows the CDDI dual-attachment connections using two RJ-45 connectors.
If you are connecting an optical bypass switch, read the next section, "Installing an Optical Bypass Switch."
An optical bypass switch is a device installed between the ring and the station that provides additional fault tolerance to the network. If an FDDI module that connects to a bypass switch fails or shuts down, the bypass switch activates automatically and allows the light signal to pass directly through it, bypassing the FDDI module completely. A port for connecting an optical bypass switch is provided on the FDDI module SMF and FDDI module MMF. (See Figure 3-13.)
The optical bypass control port on the FDDI module is a six-pin, mini-DIN receptacle. Some optical bypass switches use DIN connectors, and some use a mini-DIN.
This procedure describes how to connect an optical bypass switch to an FDDI module; however, your particular bypass switch might require a different connection scheme. Use these steps as a general guideline, but refer to the instructions provided by the optical bypass switch's manufacturer for specific connection requirements.
Step 1 Connect the bypass switch to the ring. Unless the documentation that accompanies the bypass switch instructs otherwise, use the same guidelines used to connect the ring directly to the FDDI module ports to connect the A/B ports on the bypass switch to the ring.
Step 2 Use the receive label on the cable MIC connectors as a key and connect the cables to the network (ring) side of the bypass switch as follows:
Step 3 Connect the optical bypass switch to the FDDI module. Unless the documentation that accompanies the bypass switch instructs otherwise, consider the bypass switch an extension of the FDDI module ports and connect A to A and B to B. The network cables are already connected to the bypass switch following the standard B-to-A/A-to-B scheme.
Step 4 Connect an interface cable between the PHY A port on the station (FDDI module) side of the bypass switch and the FDDI module PHY A port.
Step 5 Connect an interface cable between the PHY B port on the station (FDDI module) side of the bypass switch and the FDDI module PHY B port.
Step 6 Connect the bypass switch control cable. If the control cable on your optical bypass switch uses a mini-DIN connector, connect the cable directly to the mini-DIN optical bypass port on the FDDI module.
The physical layer interface module (PLIM) on the ATM LANE module determines the type of ATM connection. There are no restrictions on slot locations or sequence; you can install an ATM fiber-optic module in any available module slot.
SMF or MMF connections require that you have a single-mode (SC type) connector, shown in Figure 3-14, to connect the ATM LANE multimode switching module with the external ATM switch.
Connect the ATM interface cables to the appropriate ATM network connector, as shown in Figure 3-15 and Figure 3-16.
| Warning
| Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber-optic modules when no cable is connected. Avoid exposure and do not stare into open apertures. |
The ATM dual PHY DS3 modules are connected to an ATM network using 75-ohm RG-59 coaxial cable with bayonet-style twist-lock (BNC) connectors. Figure 3-17 shows the ATM dual PHY DS3 connections.
The Token Ring module (WS-X5030) is connected to a Token Ring network using 100-, 120-, or 150-ohm cable fitted with RJ-45 connectors. Figure 3-18 shows the Token Ring module connectors.
The fiber Token Ring module (WS-X5031) is connected to a Token Ring network using multimode fiber cable fitted with Volition VF-45 connectors. Figure 3-19 shows the fiber Token Ring module connectors.
For information on connecting LightStream 1010 ATM modules, refer to the LightStream 1010 ATM Switch PAM Installation Guide.
You can connect appropriate serial cables to the RSM console and auxiliary ports. For information on connecting the RSM, refer to the Catalyst 5000 Series Route Switch Module Installation and Configuration Note.
This section describes how to verify the installation of switching modules.
For complete information on configuring all modules, see the Catalyst 5000 Series Software Configuration Guide. For information on all Catalyst 5000 series switch commands, refer to the Catalyst 5000 Series Command Reference publication.
Use the show module or show port [mod_num/port_num] command to verify that the system acknowledges the new modules and has brought them online.

| Configuring Spanning-Tree Protocol | |
| Enable spanning tree. | set spantree enable [vlan] |
| Enabling Fast EtherChannel on a Fast Ethernet Interface3 | |
| Step 1 Make sure that the ports you want to channel are configured correctly. | None |
| Step 2 Ensure a loop-free topology for all channeled VLANs. | None |
| Step 3 Create an Ethernet channel. | set port channel port_list on |
| Step 4 Disable spanning tree for all channeled VLANs. | set spantree disable vlan |
The Gigabit Ethernet module (WS-X5403) uses flow control, which is a mechanism that inhibits the transmission of packets to the Gigabit Ethernet module for a period of time. In a typical case, if the Gigabit Ethernet module's receive buffer becomes full, the module transmits a "pause" packet that tells remote devices to delay sending more packets for a specified period of time. The Gigabit Ethernet module can also receive "pause" packets from other devices.
To administer flow control, use the set port flowcontrol {receive | send} mod_num/port_num {off | on | desired} command. Table 3-3 lists the flow control tasks and the commands necessary to administer them.
| Task | Command |
|---|---|
| Tell a local port to send flowcontrol packets to a remote device. | set port flowcontrol send mod_num/port_num on |
| Tell a local port to send flowcontrol packets if a remote device wants them. | set port flowcontrol send mod_num/port_num desired |
| Turn off a local port's ability to send flow control packets to a remote device. | set port flowcontrol send mod_num/port_num off |
| Require a local port to be controlled by a remote device. | set port flowcontrol receive mod_num/port_num on |
| Allow a local port to operate with an attached device that is required to send flow-control packets, or with an attached device that is not required to but may send flow-control packets. | set port flowcontrol receive mod_num/port_num desired |
| Turn off an attached device's ability to send flow-control packets to a local port. | set port flowcontrol receive mod_num/port_num off |
By default, send is set to desired and receive is set to off.
After entering the set port flowcontrol commands you see the following displays:
Console> (enable) set port flowcontrol send 3/1 on Port 3/1 will send flowcontrol to far end. Console> (enable) set port flowcontrol send 3/1 desired Port 3/1 will send flowcontrol to far end if far end supports it Console> (enable) set port flowcontrol send 3/1 off Port 3/1 will not send flowcontrol to far end Console> (enable) set port flowcontrol receive 3/1 on Port 3/1 will require far end to send flowcontrol Console> (enable) set port flowcontrol receive 3/1 desired Port 3/1 will allow far end to send flowcontrol Console> (enable) set port flowcontrol receive 3/1 off Port 3/1 will not allow far end to send flowcontrol
To display the current flow-control status and statistics, use the command show port flowcontrol. After entering the show port flowcontrol command, you see the following display:
