Disconnecting Power

Follow these guidelines when disconnecting power:

•Locate the emergency power-off switch for the room before working with the system.

•Turn off the power and disconnect the power from the circuit when working with components that are not hot-swappable or when working near the system backplane or midplane. If the system does not have an on/off switch, unplug the power cord.

•De-energize the system completely by disconnecting the power connection to all power supplies.

•For DC power supplies, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.

•Do not touch the power supply when the power cord is connected. Line voltages are present within the power supply even when the power switch is off and the power cord is connected.

Working with Lasers

Warning Class 1 laser product. Statement 1008

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

The following laser safety standards classify the Cisco MDS 9000 Family:

•Class 1 LASER PRODUCT (IEC 60825-1 2001-01)

•Class I LASER PRODUCT (complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice 50, dated July 26, 2001)

All fiber-optic ports have been tested and comply with the Class 1 limits of IEC 60825-1 and Class I limits of 21 CFR 1040.10.

Preventing EMI

When you run wires for any significant distance in an electromagnetic field, electromagnetic interference (EMI) can occur between the field and the signals on the wires. Be aware of the following:

•Bad plant wiring can result in RFI (radio frequency interference).

•Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the system, and can even create an electrical hazard by conducting power surges through lines and into the system.

To predict and remedy strong EMI, consult RFI experts.
