The Port Redirection Connections section includes the information described in Table 4.5 about the
servers that are connected to each of the ESP-4 MI serial ports. This display is meaningful only
when a serial port is being accessed using the serial redirection connection method.
To display connected server information:
Select

The Reboot operation reboots the ESP-4 MI serial hub. A reboot is usually required for the
following operations to take effect.

To reboot:
1.

After the reboot completes, the browser will try to reconnect to the hub. If this fails, or if the web
interface does not return within 30 seconds, direct your browser to the ESP-4 MI serial hub
