For your safety, before installing the system, review all safety warnings in this section.



Temperature Warning: The recommended maximum ambient temperature is 50° C (122° F). The internal temperature of the rack should be considered for safe operation.



Rack Installation Warning: Install equipment in the rack from the bottom upward. This will maintain the stability of the rack and reduce the chance of the rack's tipping over.



Heavy-Equipment Warning: Two people are required to lift an E-series router. Three people are required to install an E-series router in a rack. The equipment is extremely heavy.



Ground (Earth) Warning: Connect the E-series router or 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 E-series router, 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 E-series router, 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.
