Safety Guidelines and Warnings for Installing CTP151 Modules
Before and during the installation process, observe the following warnings:
WARNING: Do not work on the device or connect or disconnect cables during lightning
activity.
WARNING: Be sure circuit breakers for the power source are in the OFF position
before attaching power cables.
WARNING: Remove jewelry (including rings, necklaces, and watches) before working
on equipment that is connected to power lines. Metal objects heat up when connected
to power and ground and can cause serious burns or become welded to the terminals.
WARNING: Do not insert any metal object, such as a screwdriver, into an open slot
or the midplane. Doing so can cause electric shock and serious burns.
WARNING: Never attempt to repair parts of modules yourself. Only trained customer
service personnel are authorized to service parts. Call Juniper Networks Customer
Service to make arrangements to return defective modules for repair.
