Installing and removing SFP+ modules
The SFP+ (Small Form Factor Pluggable) modules convert optical signals into electrical signals and the
reverse.
The Pebble-2 module has two SFP ports, SFP1 and SFP2. SFP+ transceivers can be installed into ports
SFP1 and SFP2, however this installation procedure describes connecting the fiber cables only to the
transceiver in SFP1.
