Sentinel Telephony Card Installation Guide 4
Warning: Disconnect all interface cables (including PRI, BRI, FXS, and FXO) before unplugging
any power sources from the Mediatrix unit.
Warning: Disconnect all interface cables (including PRI, BRI, FXS, and FXO) as well as all power
sources connected to the Mediatrix unit before servicing the unit.
Warning: This equipment must be installed and maintained by service personnel. Incorrectly
connecting this equipment to a general-purpose outlet could be hazardous.
Warning: This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15 A U.S. (240 VAC,
10 A international) is used on the phase conductors (all current-carrying conductors).
Warning: The unit must be grounded at all times when connecting/disconnecting cables.
Warning: The unit must be grounded at all times when in use.
Warning: The earth ground connection between the grounding screw on the back of the
Mediatrix unit and an appropriate grounding point in your site must always be made first
and disconnected last.
Warning: Do not connect the ETH2, ETH1,LAN, and FXS connectors directly to the Public
Switched Telephone Network (PSTN), to an off premise application, an out of plant application,
any exposed plant application, or to any equipment other than the intended application,
connection may result in a safety hazard, and/or defective operation and/or equipment
damage. Exposed plant means where any portion of the circuit is subject to accidental contact
with electric lighting or power conductors operating at a voltage exceeding 300 V between
conductors or is subject to lightning strikes.
Warning: The Mediatrix unit must be installed on a circuit equipped with a breaker so that
you can easily power the unit off if required.
Warning: Hazardous network voltages may be present in PRI and FXO cables. Always
disconnect the cables from the Mediatrix unit first to avoid possible electric shock. Network
hazardous voltages may be present on the device in the area of the PRI and FXO port, even
when power is turned OFF.
Warning: Adequate earth ground connection of the Mediatrix unit is mandatory to avoid any
damage or injuries.
Warning: Hazardous network voltages might be present in WAN, LAN, Sync, and telephony
port connectors regardless of whether power to the device is OFF or ON. Use caution when
working near these connectors to avoid electric shocks.
