General Safety Precautions and Maintenance Guidelines
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
Network hazardous voltages are present in the T1 PRI cable. If you detach the cable, detach the end
away from the router first to avoid possible electric shock. Network hazardous voltages are also
present in the area of the T1 PRI (RJ-48C) ports, regardless of whether power is off or on.
Warning
The telecommunications lines must be disconnected 1) before unplugging the main power connector
or 2) while the housing is open.
Warning
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
Warning
Do not use a telephone to report a gas leak in the vicinity of the leak.
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.
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the router is
OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching
cables, detach the end away from the router first.
Warning
To reduce the risk of electric shock when servicing any individual unit, disconnect the power cord or
cords that connect the unit to the AC power strip or DC busbar. When working with a DC system,
remove the busbar connector before working on a device. Exposed live voltages are present at the
device end; exposure to these may cause injury.
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.
Warning
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
Warning
During line card installation, wear grounding wrist straps to avoid ESD damage to the card. Do not
directly touch the backplane with your hand or any metal tool, or you could shock yourself.
