Figure 4: AC power supply
Before proceeding, make sure you have the correct power supply. Check the part
number on the power supply as listed in Table 1 on page 16.
NOTICE
• Always use the power supply provided with the satellite modem. The
modem's performance may suffer if the wrong power supply is used.
• Connect the AC/DC power supply to a 100 Voltage Alternating Current (VAC)
three-wired grounded outlet. A suitable surge protector is recommended to
protect the satellite modem from possible damage due to power surges.
• Always connect the DC power cord to the HN9800 rear panel before
applying power to the power supply. If you apply power to the power
supply and then connect the DC power cord, the satellite modem may not
perform properly and could be damaged.
• Observe the power standards and requirements of the country where it is
installed.
CAUTION
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.
