Summit X450-24x Switch
The front panel of the Summit X450-24x switch (Figure 61) includes:
● Twenty fixed SFP ports (ports 5–24) that provide 20 Gbps of high-density fiber connectivity
For information about SFPS, see the Extreme Networks Pluggable Interface Modules Installation Guide.
● Four combination ports (ports 1–4) using RJ-45 connectors and SFPs to provide 4 Gbps of copper or
fiber connectivity
For more information about combination ports, see “Combination Ports and Failover” on page 22.
● 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 105.
● 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
