Installing and Removing the SFP and XFP Modules

This chapter describes how to install and remove small form-factor pluggables (SFP modules or XFP modules) on the Cisco ASR 1000 Series Fixed Ethernet Line Card. This chapter contains the following sections:

Removing and Installing SFP Modules

Note The Cisco ASR 1000 Series Fixed Ethernet Line Card will accept only the SFP modules listed as supported in this document. An SFP check is run every time an SFP module is inserted into a Cisco ASR 1000 Series Fixed Ethernet Line Card, and only those SFP modules that pass this check are usable.

Before you remove or install an SFP module, read the installation information provided in this section and the “Laser and LED Safety” section.

Caution Protect the SFP modules by inserting clean dust covers on them after the cables are removed. Ensure that you 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 We recommend that you do not install or remove the SFP module with fiber-optic cables attached to it because of potential damage to the cable, the cable connector, or the optical interfaces in the SFP module. Disconnect all the cables before removing or installing an SFP module.

Removing and inserting an SFP module can shorten its useful life. Therefore, you should not remove and insert SFP modules unless it 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

The bale clasp SFP module has a clasp that you should use to remove or install the SFP module. (See Figure 5-1.)

Figure 5-1 Bale Clasp SFP Module

Installing the 10-GE 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 when 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’s front panel.

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

Step 5 Pivot the bale clasp up such 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 fits into the transceiver socket connector.

Step 7 Latch the XFP transceiver in the transceiver socket by pivoting the bale clasp down such 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.
