Chapter 3 Removing and Installing the PA-POS-1OC3
Replacing the SFP Optics Module
Replacing the SFP Optics Module
The following section describes how to remove and install the small form-factor pluggable (SFP) optics
modules in the PA-POS-1OC3.
Note The SFP optics modules used with the PA-POS-1OC3 have LC type connectors
The SFP optics modules support online insertion and removal (OIR). However, if the port adapter is
already installed in the router and the system is operational, we recommend that you administratively
shut down the SFP port before installing a new SFP optics module.
Available Cisco SFP optics modules include the following:
• POM-OC3-MM (short range, multimode fiber)
• POM-OC3-SMIR (intermediate range, single-mode fiber)
• POM-OC3-SMLR (long range, single-mode fiber)
Handling the SFP Optics Module
Before handling the SFP optics module, observe the following guidelines:
• SFP optics modules are static-sensitive. To prevent electrostatic discharge (ESD) damage, follow
your normal board- and component-handling procedures.
• SFP optics modules are dust-sensitive. When storing an SFP optics module or when a fiber-optics
cable is not plugged into the connector, always keep plugs in the SFP optical bores.
The most common source of contaminants in the optical bores is debris picked up on the ferrules of the
optical connectors. For information about inspecting and cleaning fiber optic connections, see the
Inspection and Cleaning Procedures for Fiber-Optic Connections document at
http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml,
and the Compressed Air Cleaning Issues for Fiber-Optic Connections at
http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml.
Note We strongly recommend cleaning any optical-fiber connectors before making new connections to
optical-fiber equipment.
Removing the SFP Optics Module
The following procedure describes removing the SFP optics module from a vertically or horizontally
oriented port adapter slot.
Warning
Ultimate disposal of this product should be handled according to all national laws and regulations.
Statement 1040
Caution You can remove and install SFP optics modules with power on to the system; however, we strongly
recommend that you do not remove or install an SFP optics module with optical fiber cables attached.
