Lightning Activity Warning: Do not work on the system or connect or disconnect
cables during lightning activity.
DC Power Disconnection Warning: Before powering on the ERX system,
remove power from the DC circuit by deactivating the circuit breaker on the panel
board that services the DC circuit.
Power Connection Warning: Before servicing the ERX system, turn off the
power.
Jewelry Removal 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.
Metal Objects Warning: Do not insert any metal object, such as a screwdriver,
into an open slot or the backplane. Doing so may cause electric shock and serious
burns.
Branch Circuit Caution: Evaluate the overall loading of the branch circuit before
you install any equipment into a rack.
