Communication Server 1000M and Meridian 1
Read the following warnings carefully before you begin installing the ISP1100
Signaling Server in the rack.
DANGER OF ELECTRIC SHOCK
DISCONNECT AC POWER
The ISP1100 Signaling Server must be completely
disconnected from any AC power source before
performing this procedure. Pressing the Power button
DOES NOT turn off power to this Signaling Server.
Some circuitry in the unit can continue to operate even
though the front panel Power button is off.
Failure to disconnect the ISP1100 Signaling Server from
its AC power source can result in personal injury or
equipment damage.
DANGER OF ELECTRIC SHOCK
GROUNDING THE RACK INSTALLATION
To avoid the potential for an electrical shock hazard,
include a third wire safety grounding conductor with the
rack installation.
If the ISP1100 Signaling Server power cords are plugged
into AC outlets that are part of the rack, then provide
proper grounding for the rack itself.
If the ISP1100 Signaling Server power cords are plugged
into wall AC outlets, the safety grounding conductor in
each power cord provides proper grounding for the
ISP1100 Signaling Server only. Provide additional,
proper grounding for the rack and other devices installed
in it.
