Chapter 3 Installing and Connecting the Router
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first.
Statement 1026
Warning
Do not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry
tub, in a wet basement, or near a swimming pool.
Statement 1035
Warning
Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote
risk of electric shock from lightning.
Statement 1038
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be
accessed only through the use of a special tool, lock and key, or other means of security.
Statement 1017
Warning
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the
floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip
over.
Statement 1048
Warning
The chassis should be mounted on a rack that is permanently affixed to the building.
Statement 1049
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)
that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
Warning
A ground wire must always be a single piece of wire. Never splice two wires together for a ground.
Corrosion and weathering can lead to a poor connection at the splice, making the ground ineffective
and dangerous.
Statement 270
Warning
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Statement 1023
Warning
Use copper conductors only.
