Sf Module Leds In An Ex8208 Switch - Juniper EX8208 Hardware Manual

configuration, the main function of the SF module is to provide a redundant switching plane for the switch.
See "Understanding EX8208 Switch Component and Functionality Redundancy" on page
In a redundant configuration, the SF module is hot-pluggable. However, in the base configuration, you
must take the SF module offline before removing it.
The SF module contains logic that determines which SRE module is the primary. The primary SRE module
controls many internal functions of the SF module.
The SF module provides these functions:
Provide redundant data path connectivity for the switch in the redundant configuration
Provide nonredundant data path connectivity for the switch in the base configuration
The SF module has these components:
SF module LEDs—Indicate system status. See
Ejector levers—Used for installing and removing the SF module.
Captive screws—Secure the SF module in place.
