Overview

The Cisco TwinGig Converter Module (model CVR-X2-SFP), also known as the converter module, is a hot-swappable input/output (I/O) device that slides into a 10-Gigabit Ethernet slot on a Catalyst 3750-E or 3560-E switch. It converts the 10-Gigabit interface into a dual SFP interface. The converter module is shown in Figure 1.

1 A mode-conditioning patch cord is required. An ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).

2 ITU-T G.652 SMF as specified by the IEEE 802.3z standard.

3 1000BASE-ZX and CWDM SFP modules can send data up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on the fiber quality, the number of splices, and the connectors.


Converter Module Installation

This section describes how to install and remove the converter module in a Catalyst 3750-E or 3560-E switch and how to install and remove the SFP modules. It contains these sections:

• Safety Warnings

• Installation Guidelines

• Installing and Removing the Converter Module

• Installing and Removing SFP Modules

Safety Warnings

This section includes the basic installation caution and warning statements. Translations of the warning statements appear in the Regulatory Compliance and Safety Information for the Catalyst 3750-E and Catalyst 3560-E document that ships with the switch. Read this section before you start the installation procedure.

Caution Proper ESD protection is required whenever you handle Cisco equipment. Installation and maintenance personnel should be properly grounded by means of grounding straps to eliminate the risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever it is removed from the switch.

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. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 148

Warning Do not reach into a vacant slot or chassis while you install or remove a module. Exposed circuitry could constitute an energy hazard. Statement 206

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

Warning Class 1 laser product. Statement 1008

Installation Guidelines

Follow these guidelines when working with the converter module or an SFP module:

•The converter module and SFP module are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that is connected to the chassis. Place the module in an antistatic bag when not in use.

•Verify the correct orientation of the converter module or SFP module before inserting it into the slot. Incorrect insertion can damage the module or the switch.

•Do not install or remove the converter module with the SFP modules installed. Always remove any SFP cables and SFP modules from the converter module before installing it in the switch.

•Do not install or remove an SFP module with the cables attached because of the potential damage to the cables, the cable connector, or the optical interfaces in the module. Disconnect all cables before removing or installing the SFP module.

•Verify that the converter module is straight and not at an angle when you install it in the slot. Installing the module at an angle can damage it. Any module that is only partially connected to the switch might not operate correctly.

•Do not force the converter module into its slot. This can damage the pins if they are not aligned with the module.

•Do not remove the EMI plug from the converter module, the dust plug from the SFP module, or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

•Removing and installing the converter module or SFP module can shorten its useful life. Do not remove and insert a module more often than is absolutely necessary.

Note The Catalyst 3750-E and 3560-E switches support hot swapping of the converter module. You can remove and replace the module without disconnecting the system power. Hot swapping the module does not interrupt normal switch operation.

Installing and Removing the Converter Module

These sections describe how to install and remove the Cisco TwinGig Converter Module in the switch 10-Gigabit Ethernet module slots.

Note When you install or remove the converter module, the mode on the switch changes from 10 Gigabit Ethernet to Gigabit Ethernet or the reverse. During this mode change, data traffic on the other switch uplink ports (X2 transceiver or SFP module ports) might temporarily stop. When you install or remove an X2 transceiver or SFP module, traffic delay does not occur.

Installing the Converter Module

To install the converter module in the switch module slot, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2 Remove the 10-Gigabit Ethernet module slot EMC plugs and save.

Caution Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install the converter module. A module or an EMC plug must be installed in the slot at all times.

Step 3 Remove the converter module from its protective packaging.

Caution Do not install the converter module with the SFP modules installed. Always remove any cables and SFP modules before installing the converter module in the switch.
Caution Verify the correct orientation of the converter module before inserting it into the slot. Incorrect insertion can damage the module.

Step 4 Slide the converter module gently but firmly into the 10-Gigabit switch module slot until the converter module is flush with the switch faceplate and the converter module snaps into place.

When using the switch upper 10-Gigabit Ethernet module slot (slot1), insert the converter module face up. When using the switch lower module slot (slot 2), insert the converter module face down ( Figure 2).

Step 5 Install the SFP module into the converter module (See the "Installing an SFP Module" section). The switch detects the presence of both the converter module and any inserted Cisco SFP modules.

Removing the Converter Module

To remove the converter module from the switch module slot, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2 Disconnect the cables from the SFP module and remove the SFP modules from the converter module. (See the "Installing and Removing SFP Modules" section).

Step 3 Pinch the latch arms on each side of the converter module, and carefully slide it out of the slot ( Figure 3).

Step 4 Place all SFP modules and converter modules in an antistatic bag or other protective environment.

Step 5 Replace the EMI plug in the switch empty 10-Gigabit Ethernet module slot.

Figure 3 Removing the Converter Module from the Catalyst 3750-E and 3560-E Switch

Installing and Removing SFP Modules

This section describes how to install and remove SFP modules in the converter module slots. You must have the converter module installed in a 10-Gigabit Ethernet switch slot to use SFP modules with the switch. Figure 4 shows the converter module in the switch with the SFP modules installed.

For detailed information about installing, removing, cabling, and troubleshooting SFP modules, see the module documentation that shipped with your device.

Caution To avoid damage to the converter module, first install the converter module in the switch 10-Gigabit Ethernet slot before installing the SFP modules.

Note Do not install or remove the SFP module with cables attached to it because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.

Installing an SFP Module

Caution Verify the correct orientation of the SFP module before inserting it into the converter module. Incorrect insertion can damage the converter module, the SFP module, or the switch.

To insert an SFP module into a converter module slot, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send (arrow pointing out) or receive (arrow pointing).

•When installing an SFP module in the switch upper 10-Gigabit Ethernet module slot (slot 1), insert the SFP module face up. When installing an SFP module in the switch lower module slot (slot 2), insert the SFP module face down.

•If you are using an SFP module patch cable, and the converter module is installed in the switch upper 10-Gigabit Ethernet module slot (slot 1), insert the SFP patch cable into the converter module with the label facing up. If the converter module is installed in the switch lower module slot (slot 2), insert the patch cable into the converter module with the label facing down ( Figure 5).

Step 3 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Step 4 Slide the SFP module or the patch cable into the opening until you feel the connector on the module snap into place.

Step 5 If the module has a bale-clasp latch, close it to lock the SFP module in place.

Step 6 Remove the dust plugs from the SFP module and save. Attach the cables to the SFP module.

Removing an SFP Module

To remove an SFP module from the converter module, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2 Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX).

Step 3 Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.

Step 4 If the SFP module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch.

Step 5 Grasp the SFP module, and carefully remove it from the converter module.

Step 6 Place the removed SFP module in an antistatic bag or other protective environment.
