Rescue switch
Do not use the recessed rescue switch on the modem’s rear panel unless you are a qualified technician. Pressing this
switch could cause the modem to become inoperable.
Cannot Access the System Control Center
Follow these steps if you cannot access the System Control Center after installation of the satellite modem.
1. If the modem is using a private IP address, confirm that DHCP is enabled on the computer.
This procedure is explained in
Configuring a computer to use DHCP on page 51.
2. Open a web browser on a computer connected to the satellite modem.
3.
In the browser address bar, type
www.systemcontrolcenter.com
or
192.168.0.1
and press Enter .
Note: To use 192.168.0.1 , the satellite modem must be configured for a private IP address, and DHCP must
be enabled on the computer.
If the System Control Center does not appear, continue with the remaining steps.
4. Make sure that the satellite modem is powered up. The Power and LAN LEDs should be continuously lit—except
that the LAN LED may blink if there is LAN activity.
5. Make sure the DC power cord adapter is securely attached to the satellite modem.
6. If the LEDs are off, make sure the Ethernet cable is securely attached to the satellite modem and the computer.
7. If you still cannot access the System Control Center, contact Hughes Customer Care for assistance.
Testing connectivity to the satellite
If you have problems connecting to the Internet, you can use the Connectivity Test page to test connectivity between
the modem and the satellite. This connectivity test sends test messages on a loop from the modem to the satellite and
back to the modem, as shown in
Figure 25: Satellite loopback connectivity test on page 45. If the test succeeds, it verifies
that the modem can connect to the satellite.
