Four 1000BASE-T Copper Interfaces
Use the following table to understand the link and activity LEDs on copper
interfaces.
Use the following table to understand the bypass LED on copper interfaces.
SFP Interfaces
You can install up to eight hot-swappable Sourcefire SFP transceivers, available in
1G copper, 1G short range fiber, or 1G long range fiber. SFP transceivers do not
have bypass capability and should not be used in intrusion prevention
deployments. See
Using SFP Transceivers on a 3D7115 or 3D7125 on page 251
