Port speeds
The external switch ports can support 1, 2, 4, or 8 Gbps. The internal ports only
support 2, 4, and 8 Gbps. All ports can be configured for either a fixed transmission
speed or to sense (auto-detect) the transmission speed of the device to which it is
connected. To display the speed of each port, open the View menu and select View
Port Speeds. Table 25 lists the possible port speeds.
To change the port transmission speed, do the following:
1. Select one or more ports in the faceplate display.
2. Open the Port menu and select Port Properties to open the Port Properties
dialog.
3. Select the Port Speed option from the drop-down list.
4. Click the OK button to write the new port speed to the switch.
