Hughes HN9200, Installation Manual

Page: 96 / 132

Important troubleshooting information
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.
This installation guide contains some procedures that instruct you
to restart the modem using the Restart function in the System Control Center. When so instructed,
do not power cycle the modem. Doing so will destroy data that may be useful for troubleshooting.
When this installation guide instructs you to power
cycle the modem, you should remove and then re-apply power. If the satellite modem uses an
AC/DC power supply, disconnect the AC power cord from the power source (power strip, wall
outlet, or surge protector). If the satellite modem uses a DC/DC power supply, disconnect the
DC input cable connector from the modem’s power supply. In either case (AC/DC or DC/DC),
do not unplug the power cord from the satellite modem’s rear panel. Doing so could result in
static electricity discharge that could shock you and/or damage the modem.
