General Safety
Recommendations
Before installing your switch, note the following safety recommendations:
■
Switch off the power supply before connecting the cables.
■
Keep the switch away from heat sources.
■
To ensure normal heat dissipation, do not stack switches.
■
Do not keep the switch in a damp place, and prevent liquid from getting into
the switch.
■
Ensure that the neutral point of the power is grounded properly, to avoid
personal injury.
■
Ensure that the power is off before plugging or unplugging the modules and
cables of the switch.
■
Before moving the chassis, disconnect all the power cords and external cables.
■
To avoid damage to the switch, connect all the cables correctly. Never connect
telephone cables (including the ISDN lines) to the console or AUX port.
