Safety Recommendations

Follow these guidelines to ensure general safety:

• Keep the chassis area clear and dust-free during and after installation.

• Put the removed chassis cover in a safe place.

• Keep tools away from walk areas where you and others could fall over them.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll

up your sleeves.

Safety Recommendations

• Wear safety glasses if you are working under any conditions that might be hazardous to your

eyes.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

• Locate the emergency power-OFF switch for the room in which you are working. Then, if an

electrical accident occurs, you can act quickly to turn OFF the power.

• Disconnect all power by turning OFF the power and unplugging the power cord before:

— Installing or removing a chassis

— Working near power supplies

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit; always check the circuit.

• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power

extension cables, frayed power cords, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

— Use caution; do not become a victim yourself.

— Turn OFF power to the system.

— If possible, send another person to get medical aid. Otherwise, assess the condition of the

victim and then call for help.

— Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when
electronic components are improperly handled and can result in complete or intermittent failures.

• Always follow ESD-prevention procedures when removing and replacing components. Ensure

that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap,
ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of
the chassis frame to safely ground ESD voltages. To properly guard against ESD damage and
shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground
yourself by touching the metal part of the chassis.

• For safety, periodically check the resistance value of the antistatic strap, which should be between

1 and 10 megohms (Mohms).

2 Regulatory Compliance and Safety Information for the Cisco Micro Hub

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your system.
Ensure that your site is properly prepared before beginning installation.

Preventive Site Configuration

The following precautions will help you plan an acceptable operating environment for your Cisco Micro Hub and
will help you avoid environmentally caused equipment failures:

• Electrical equipment generates heat. Ambient air temperature might not be adequate to cool

equipment to acceptable operating temperatures without adequate circulation. Ensure that the
room in which you operate your system has adequate air circulation.

• Always follow the ESD-prevention procedures described previously to avoid damage to

equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow

effectively within it. An open chassis allows air leaks, which may interrupt and redirect the flow
of cooling air from internal components.

Power Supply Considerations

Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install a
power conditioner if necessary.

General Site Requirements

The hubs’ power supply includes the following features:

• Autoselects 100V, 110V, 220V, or 240V operation.

• All units include an AC power line cord.

Agency Approvals

All models of the Cisco Micro Hub meet the requirements for the following agency approvals:

• Emissions—EN55022 Class B; FCC 47, Part 15, Class B; VCCI Class 2; AS/NRZ 3548:1992,

Class B; ICES-003, Issue 2, Class B, April 1995

• Immunity—IEC1000-3-2, IEC1000-4-2, IEC1000-4-3, IEC1000-4-4, IEC1000-4-5,

IEC1000-4-6

Directives Compliance

The CE-0168-X or CE-0344-X mark signifies that the equipment complies with the following
European Directives: 91/263/EEC (public telecommunications network compatibility), 89/336/EEC
(electromagnetic compatibility), 73/23/EEC (low voltage), and 92/59/EEC (general product safety).
