NOTE: When you install an expansion module in the switch or replace an
expansion module with another expansion module, the switch detects the
ports on the expansion module. The switch creates the required interfaces
when transceivers are installed in these ports.
Each expansion module has an LED on the faceplate (labeled ST). It indicates the status
of the expansion module.
Figure 11 on page 25 shows the location of LEDs on the SFP+ expansion module.
