14 General description
FC ports
The switch has 2 external FC ports through which to connect to devices or other switches, and 8 internal
ports connecting to the server backplane. Each of the external FC ports is served by a Small Form-Factor
Pluggable (SFP) optical transceiver and is capable of 1-Gbps, 2-Gbps, or 4-Gbps transmission. SFPs are
hot-pluggable. External ports can self-discover both the port type and transmission speed when connected
to public devices or other switches. The internal ports operate at 2-Gbps.
The external ports are named Ext:0, Ext:9 and are labeled 0 and 9 as shown in Figure 4 . The external port
LEDs provide port login and activity status information. Internal ports are named Int:1–Int:8 and numbered
1–8. The ports 1–8 correspond to server blade slots 1–8 in the server chassis.
