Summit X450a-24xDC Switch
The front panel of the Summit X450a-24xDC switch (Figure 27) includes:
● Twenty fixed autosensing 1000BASE-X ports (ports 1-20) that provide 20 Gbps of high-density fiber
(SFP) connectivity
● Four combination ports (ports 21-24). using RJ-45 connectors and SFPs to provide 4 Gbps of copper
or fiber connectivity
For information about SFPs, see the Extreme Networks Pluggable Interface Modules Installation Guide.
● LEDs to indicate port status and switch operating conditions. For a description of the LEDs and their
operation, see “Summit X450, X450a, and X450e Series Switch LEDs” on page 43.
● Stack number indicator showing the position of this switch in a stacked configuration.
● Serial console port used to connect a terminal and perform local management.
