Small form-factor pluggable modules

The Sensor uses two types of small form-factor pluggable modules as shown in the following table:

Type Performance

SFP 10/100/1000 Mbps (copper)

1 Gbps (fiber optic)

XFP 10 Gbps (fiber optic)

Each module is a hot-swappable input/output device that plugs into an LC-type Gigabit Ethernet port,

linking the module port with a copper or fiber-optic network. SFP optical interfaces are less than half

the size of GBIC interfaces.

To ensure compatibility, McAfee supports only those SFP and XFP modules purchased through McAfee

or from a McAfee-approved vendor. For a list of approved vendors, locate the relevant KnowledgeBase

article at http://mysupport.mcafee.com/Eservice/. Click Search the KnowledgeBase.

These installation instructions provide information for installing SFP and XFP modules that use a bail

clasp for securing the module in place in the Sensor. Your module might be slightly different. Check

the module manufacturer's installation instructions for more details. For ease of installation, insert the

module in the Sensor while it is powered down and before placing it on a rack.

To prevent eye damage, do not stare into open laser apertures.

SFP modules

An SFP module is a hot-swappable, protocol-independant, compact, optical receiver, which allows for

greater port density than the standard GBIC. This module operates at varying speeds for up to 1

gigabit per second on SONET/SDH, Fibre Channel, Gigabit Ethernet and other applications. An SFP

module operates in single mode and multimode. Additionally, this module transmits on a

850-nanometer wavelength on short reach (SR) and 1310-nanometer wavelength on long reach (LR).
