Safety Warnings Summary
This is a summary of safety warnings. For a complete list of warnings, including
translations, see the QFX5110 switch documentation at
http://www.juniper.net/techpubs/ .
WARNING:
Failure to observe these safety warnings can result in personal injury
or death.
z
Permit only trained and qualified personnel to install or replace switch components.
z
Perform only the procedures described in this quick start and the QFX5110 switch
documentation. Other services must be performed only by authorized service
personnel.
z
Before installing the switch, read the planning instructions in the QFX5110 switch
documentation to make sure that the site meets power, environmental, and clearance
requirements for the switch.
z
Before connecting the switch to a power source, read the installation instructions in the
QFX5110 switch documentation.
z
The QFX5110-48S switch weighs approximately 23 lb (10.4 kg). Manually installing the
QFX5110-48S switch in a rack or cabinet at a height above 60 in. (152.4 cm) requires
two persons to lift the switch and install mounting screws. To prevent injury, keep your
back straight and lift with your legs, not your back.
z
If the rack or cabinet has stabilizing devices, install them in the rack before mounting or
servicing the switch in the rack or cabinet.
z
Before installing or after removing an electrical component, always place it
component-side up on a flat antistatic mat or in an antistatic bag.
z
Do not work on the switch or connect or disconnect cables during electrical storms.
z
Before working on equipment that is connected to power lines, remove jewelry,
including rings, necklaces, and watches. Metal objects heat up when connected to
power and ground and can cause serious burns or become welded to the terminals.
CAUTION:
Do not place a copper transceiver in an access port directly above or
below another copper transceiver. Damage to the access ports will occur.
Power Cable Warning (Japanese)
The attached power cable is only for
this product. Do not use this cable for
another product.
