Safety Guidelines
Hazardous Conditions Inside the Switch
Hazardous voltage, current, and energy levels are present inside the Switch. Do
not open the Switch; there are no user-serviceable parts inside. Contact Nortel
Networks Customer Support for service.
Switch Power ON/OFF
The On/Off power button on the front panel of the Switch does not completely
eliminate (turn off) the AC power from the Switch. To eliminate AC power from
the Switch completely, unplug the AC power cord from the power supply or wall
outlet.
Check the Voltage Switch
Before you connect the power cord to the back panel of the Switch, ensure that the
voltage selector switch is correctly set to the appropriate AC line source voltage.
For line voltages between:
• 100 and 127 VAC, set the power supply line voltage selector to
115V (115 VAC).
• 200 and 240 VAC, set the power supply line voltage selector to
230V (230 VAC).
Verify that the correct voltage (115V or 230V) is visible on the switch. See Figure
3-1 on page 3-2.
WARNING: Incorrectly setting the voltage will damage the
power supply. See Figure 3-1 on page 3-2.
CAUTION: Make sure that the power service connection is through an
outlet that is properly grounded.
