Preparing to Install the Router 2-3
Maintaining Safety with Electricity
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, frayed power cords, and missing safety grounds.
• Locate the emergency power off switch for the room in which you are working. Then,
if an electrical accident occurs, you can act quickly to turn OFF the power.
• Power OFF the router and unplug the power cord before doing the following:
— Installing or removing a chassis
— Working near power supplies
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
Warning Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units.
Warning Do not touch the power supply when the power cord is connected. For systems
with a power switch, line voltages are present within the power supply even when the
power switch is OFF and the power cord is connected. For systems without a power
switch, line voltages are present within the power supply when the power cord is
connected.
Warning Incorrect connection of this or connected equipment to a general purpose outlet
could result in a hazardous situation.
Warning This equipment is to be installed and maintained by service personnel only as
defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.
Warning Read the installation instructions before you connect the system to its power
source.
