Safety Guidelines

Observe the following guidelines when cabling your ERX system.



Ground (Earth) Warning:
Connect either the freestanding ERX system or the rack to ground (earth), and ensure that a reliable grounding path is maintained in the rack.



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.



Servicing Unit 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 weld the metal object 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.



Note: If you plan on using a cable-management bracket, install it before you begin cabling your ERX system. Cable-management brackets are helpful to keep network interface cables untangled and orderly and to prevent cables from hindering access to other slots.
