Safety Recommendations
CHAP T E R
2
Note The RPM-XF is a service module that fits in the Cisco MGX 8850 chassis. Refer to the Cisco MGX 8850
Routing Switch Installation Guide for further recommendations about safety.
The guidelines that follow help ensure your safety and protect the Cisco MGX 8850 equipment. The list
of guidelines may not address all potentially hazardous situations in your working environment, so be
alert, and exercise good judgement at all times.
The safety guidelines are as follows:
• Keep the chassis area clear and dust-free before, during, and after installation.
• Keep tools away from walk areas where people could fall over them.
• Do not wear loose clothing or jewelry, such as rings, bracelets, or chains, which may become caught
in the chassis.
• Wear safety glasses if you are working under any conditions that may be hazardous to your eyes.
• Do not perform any actions that create a potential hazard to people or make the equipment unsafe.
• Never attempt to lift an object that is too heavy for one person to handle.

Warning
Before working on a chassis or working near power supplies, unplug the power cords on an
AC-powered system. On a DC-powered system, disconnect the power at the circuit breakers.
Follow these guidelines when working on equipment powered by electricity:
• Locate the emergency power-off switch for the room in which you are working. If an electrical
accident occurs, you can quickly turn off the power.
• Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
• Never assume that power is disconnected from a circuit—Always check the circuit.
• Carefully look for possible hazards in your work area, such as moist floors, ungrounded power
extension cords, or missing safety grounds.
• If an electrical accident occurs:
–
Use caution—Do not let yourself become a victim.
–
Disconnect power from the system.
–
If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
then call for help.
• Use the Cisco MGX 8850 AC and MGX 8850 DC systems within their marked electrical ratings and
product usage instructions.
• Install the Cisco MGX 8850 AC or MGX 8850 DC systems with the following local, national, or
international electrical codes:
–
United States—National Fire Protection Association (NFPA70), United States National
Electrical Code.
–
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
–
Other countries—International Electromechanical Commission (IEC) 364, Part 1 through
Part 7.
• Cisco MGX 8850 AC models are shipped with a 3-wire electrical cord with a grounding-type plug
that fits only a grounding type power outlet. This is a safety feature that you should not circumvent.
Equipment grounding should comply with local and national electrical codes.
• Cisco MGX 8850 DC models are equipped with DC power entry modules and require you to
terminate the DC input wiring on a DC source capable of supplying at least 60A. A 60A circuit
breaker is required at the 48 VDC facility power source. An easily accessible disconnect device
should be incorporated into the facility wiring. Be sure to connect the grounding wire conduit to a
solid earth ground. A closed loop ring is recommended to terminate the ground conductor at the
ground stud.
• Other DC power guidelines are as follows:
–
Only a DC power source that complies with the safety extra low voltage (SELV) requirements
of UL 1950, CSA C22.2 No. 950-95, EN 60950 and IEC 950 can be connected to a Cisco MGX
8850 DC-input power entry module.
–
Cisco MGX 8850 DC which is equipped with DC power entry modules is intended only for
installation in a restricted access location. In the United States, a restricted access area is in
accordance with Articles 110–16, 110–17, and 110–18 of the National Electrical Code
ANSI/NFPA 70.
