Chapter 1 Overview Cisco 7201 Hardware Overview
SFP Module Information
You may have ordered a small form-factor pluggable (SFP) module with your Cisco 7201 router. You
must install the SFP module. It is shipped separately to prevent damage during shipment. After reading
this section, use the installation instructions in the “Removing and Installing an SFP Module” section on
page 4-2 to install the SFP modules.
For ease of installation, insert the SFP module in the router while it is powered down and before placing
it in a rack.
The SFP port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE
802.3z interfaces compliant with the 1000BASEX standard. Gigabit Ethernet SFP models SFP-GE-S,
SFP-GE-L, SFP-GE-Z, and SFP-GE-Fare supported in the Cisco 7201 router, as well as the SFP-GE-T.
The cabling information is the same for all optical SFP modules.
Also see the “SFP Module Specifications and Configurations” section on page A-4, and the Gigabit
Interface Converter (GBIC) Module and Small Form-F actor Pluggable (SFP) GBIC Module Installation
Information and Specifications document.
For optical connection cleaning information, see the Inspection and Cleaning Procedures for Fiber-Optic
Connections document and the Compressed Air Cleaning Issues for Fiber-Optic Connections document.
Figure 1-3 Types of SFP Module Latches
Note The SFP module must be installed before you connect the cables to it.
• The SPF module has three types of latches, which are also the removal mechanism. See Figure 1-3.
There is no correlation of the type of latch to the model (such as SX or LH/LX) or technology type
(such as Gigabit Ethernet) of SFP modules. Always read the label on the SFP module to determine
the technology type and model.
• You can install and remove Gigabit Ethernet SFP modules with power on to the system.
