Adapter LED operation (stand-up adapters)
Figure 20 illustrates LED indicator locations on a Brocade 825 and a Brocade 815. LED indicators
for each port are visible through the mounting brackets. Since the Brocade 825 operates at speeds
up to 8 Gbps, each port has a 1|2, 4, and 8 Gbps LED. The 4 Gbps models, such as the Brocade
415 and Brocade 425, have a 1|2 and 4 Gbps LED for each port.
