Juniper EX3300 Complete Hardware Guide

•
Never install electrical jacks in wet locations unless the jacks are specifically designed
for wet environments.
•
Operate the device only when it is properly grounded.
•
Ensure that the separate protective earthing terminal provided on this device is
permanently connected to earth.
•
Replace fuses only with fuses of the same type and rating.
•
Do not open or remove chassis covers or sheet-metal parts unless instructions are
provided in the hardware documentation for this device. Such an action could cause
severe electrical shock.
•
Do not push or force any objects through any opening in the chassis frame. Such an
action could result in electrical shock or fire.
•
Avoid spilling liquid onto the chassis or onto any device component. Such an action
could cause electrical shock or damage the device.
•
Avoid touching uninsulated electrical wires or terminals that have not been
disconnected from their power source. Such an action could cause electrical shock.
•
Always ensure that all modules, power supplies, and cover panels are fully inserted
and that the installation screws are fully tightened.
