Installing and Removing SFP and XFP Modules


This chapter describes how to install or remove small form-factor pluggables (SFP modules or XFP modules) on the Cisco 7600 Series Ethernet Services 20G (ES20) line card. This chapter contains the following sections:

Removing and Installing SFP Modules.

Removing and Installing XFP Modules.

Removing and Installing SFP Modules


Note The Cisco 7600-ES20-GE will only support the SFP modules listed in this document. An SFP check is run every time an SFP module is inserted into a Cisco 7600-ES20-GE and only SFP modules that pass this check are usable.


Before you remove or install an SFP module, read the installation information in this section and the "Laser/LED Safety" section on page 3-8.


Caution Protect the SFP modules by inserting clean dust covers into them after the cables are removed. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another SFP module. Avoid getting dust and other contaminants into the optical ports of your SFP modules, because the optics will not work correctly when obstructed with dust.


Caution It is strongly recommended that you do not install or remove the SFP module with fiber-optic cables attached to it because of the potential of damaging the cable, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.
Removing and inserting an SFP module can shorten its useful life, so you should not remove and insert SFP modules any more often than is absolutely necessary.

SFP modules use one of four different latching devices to install and remove the module from a port. The four types of SFP module latching devices are described in the following sections:

Bale Clasp SFP Module

Installing the 10-Gigabit XFP Transceiver Module


Caution The XFP transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling XFP transceivers or coming into contact with system modules.

To install an XFP transceiver, follow these steps:


Step 1 Remove the XFP transceiver from its protective packaging.


Note Do not remove the optical bore dust plugs until directed to do so later in the procedure.


Step 2 Check the label on the XFP transceiver body to verify that you have the correct model for your network.

Step 3 Position the XFP transceiver in front of the XFP socket opening on the module. Slide the XFP transceiver part of the way into the transceiver socket on the system module front panel.

Step 4 Remove the optical bore dust plug from the XFP transceiver.

Step 5 Pivot the bale clasp up so that it is parallel with the transceiver body. (See Figure 5-15.)

Step 6 Continue sliding the XFP transceiver into the socket until the XFP transceiver is mated with the transceiver socket connector.

Step 7 Latch the XFP transceiver in the transceiver socket by pivoting the bale clasp down so that the bale clasp is perpendicular to the transceiver body. (See Figure 5-15.)


Caution If the latch is not fully engaged, you may accidently disconnect the XFP transceiver.

Step 8 Immediately reinstall the dust plug in the XFP transceiver optical bores. Do not remove the dust plug until you are ready to attach the network interface cable.

Figure 5-15 Installing the 10-Gigabit XFP Transceiver Module


Note 10-Gigabit XFP transceivers are keyed to prevent incorrect insertion.



Note Before removing the dust plugs and making any optical connections, follow these guidelines:

Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.

Always inspect and clean the LC connector end faces just before making any connections. Refer to the Tip on this page for a pointer to a fiber-optic inspection and cleaning white paper.

Always grasp the LC connector housing to plug or unplug a fiber-optic cable.


a. Remove the dust plugs from the optical network interface cable LC connectors. Save the dust plugs for future use.

b. Inspect and clean the LC connector's fiber-optic end faces.
