If there is any reason to remove power from the satellite modem, always unplug the AC power cord from the power
source (power outlet, power strip, or surge protector). Do not remove the DC power cord from the modem’s rear panel.
Doing so could result in an electrical shock or damage the modem.
When you re-apply power to the modem, plug the AC power cord into the power source.
Modem operating position
Operate the HN9000 modem only in a vertical position, that is, resting on its built-in base as shown in Figure 6: HN9000
in vertical position on page 5. In any other position, the modem may overheat and malfunction because of inadequate
ventilation.
Figure 6: HN9000 in vertical position
To avoid overheating, operate the HN9000 modem only in the upright vertical position as shown in Figure 6: HN9000
in vertical position on page 5.
Computer requirements
The computer that connects to the satellite modem must meet the following minimum requirements. Requirements are
listed by operating system.
All requirements are minimum requirements except those identied as recommended.
The satellite modem may work with a computer that does not meet these requirements, but Hughes supports only
computers that meet these requirements. When your HughesNet service was activated, the activation software automatically
checked your computer to make sure it meets the minimum requirements. If it did not meet all requirements, but nearly
did, you may have been given a choice to proceed with service activation anyway.
