Safety Recommendations
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide
2-4
•Enlist the assistance of a second person when lifting the router; do not attempt to lift the
router by yourself.
•Secure your footing when lifting the router; balance the lifted weight between your feet.
•Lift the assembly slowly; avoid making sudden movements; avoid twisting your body
as you lift.
•Keep your back straight and lift with your legs. If you must bend down to lift the router,
bend at your knees, rather than your waist, to reduce the strain on your lower back.
•Always disconnect all external cables before lifting or moving the router.
Caution Never attempt to lift, tilt, or move the router using the carrying handles on the
AC-input and DC-input power supplies. These handles are meant to help you carry the
power supplies; they are not designed to support the weight of the router.
Safety with Electricity
The line cards, a redundant CSC, the SFCs, the fan trays, and a redundant power supply can
be removed and replaced while the system is running. In removing such components, there
is no danger that an electrical hazard or system damage will result.
Observe the following basic guidelines when working with any electrical equipment:
•Before beginning any procedure that requires access to the interior of the router, locate
the emergency power-off switch for the room in which you will be working.
•If an electrical accident occurs and someone is hurt, proceed as follows:
—Use caution; do not become a victim yourself. Disconnect power from the system.
—If possible, send another person to get medical aid; otherwise, assess the con dit ion
of the victim and call for help.
—Determine if the person needs rescue breathing or external cardiac compressions;
take appropriate action.
•Disconnect all power and external cables before installing or removing a router.
•Never assume that power has been disconnected from a circuit; always check
beforehand.
