Warnings

These warnings are translated into several languages in the Regulatory Compliance and Safety

Information for the Cisco ME 3400E Ethernet Access Switches document that ships with the switch.

These warning statements apply to all the switches:

Warning

Before working on equipment that is connected to power lines, remove jewelry (including rings,

necklaces, and watches). Metal objects will heat up when connected to power and ground and can

cause serious burns or weld the metal object to the terminals.

Statement 43

Warning

Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury

and equipment damage.

Statement 48

Chapter 2 Switch Installation

Warnings

Warning

Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous

voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might

disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate

the system unless all cards and faceplates are in place.

Statement 156

Warning

Ethernet cables must be shielded when used in a central office environment.

Statement 171

Note Ethernet cables must be shielded and grounded at both ends when they are used in a central office

environment.

Warning

Read the wall-mounting instructions carefully before beginning installation. Failure to use the

correct hardware or to follow the correct procedures could result in a hazardous situation to people

and damage to the system.

Statement 378

Warning

Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Warning

Read the installation instructions before connecting the system to the power source.

Statement 1004

Warning

Class 1 laser product.

Statement 1008

Warning

This unit is intended for installation in restricted access areas. A restricted access area can be

accessed only through the use of a special tool, lock and key, or other means of security.

Statement 1017

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special

precautions to ensure that the system remains stable. The following guidelines are provided to

ensure your safety:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest

component at the bottom of the rack.

• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in

the rack.

Warnings

Warning

The plug-socket combination must be accessible at all times, because it serves as the main

disconnecting device.

Statement 1019

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the

absence of a suitably installed ground conductor. Contact the appropriate electrical inspection

authority or an electrician if you are uncertain that suitable grounding is available.

Statement 1024

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

Ultimate disposal of this product should be handled according to all national laws and regulations.

Statement 1040

Warning

For connections outside the building where the equipment is installed, the following ports must be

connected through an approved network termination unit with integral circuit protection.

10/100/1000 Ethernet

Statement 1044

Warning

When installing or replacing the unit, the ground connection must always be made first and

disconnected last.

Statement 1046

Warning

No user-serviceable parts inside. Do not open.

Statement 1073

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

Caution To comply with the Telcordia GR-1089 Network Equipment Building Systems (NEBS) standard for

electromagnetic compatibility and safety, connect the Ethernet cables only to intrabuilding or

nonexposed wiring or cabling.

Note The grounding architecture of this product is DC-isolated (DC-I).

You can use the grounding lug to attach a wrist strap for ESD protection during servicing.

Installation Guidelines

These warning statements apply to the Cisco ME 3400E-24TS-M and the Cisco ME 3400EG-12CS-M:

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum

recommended ambient temperature of:

149°F (65°C)

Statement 1047

Warning

This unit might have more than one power supply connection. All connections must be removed to

de-energize the unit.

Statement 1028

This warning statement applies to the Cisco ME 3400EG-2CS-A:

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum

recommended ambient temperature of:

140°F (60°C)

Statement 1047

Installation Guidelines

Before installing the switch, verify that these guidelines are met:

•For Ethernet ports, including the 10/100, the 10/100/1000 dual-purpose, and 1000BASE-T SFP

module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

•For cable requirements for SFP module connections, see the “Cable Pinouts” section on page B-6.

•Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”

•Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling.

•AC-power cord reaches from the power outlet to the connector.

•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent

lighting fixtures. Make sure that the cabling is safely away from other devices that might damage

the cables.

•Airflow around the switch and through the vents is unrestricted.

Note If the switch is installed in a closed or multirack assembly, the temperature around it might be

greater than normal room temperature.

•Before you connect the switch to a power source, note the power consumption specifications in

Appendix A, “Technical Specifications.”

Chapter 2 Switch Installation

Verifying Switch Operation

Before installing the switch in a rack, on a wall, on a table, or on a shelf, you should power the switch

and verify that the switch passes the power-on self-test (POST).

•To power on the Cisco ME 3400E-24TS-M and Cisco ME 3400EG-12CS-M, see Chapter 3,

“Installing and Removing AC- and DC-Power-Supply Modules.”

•To power on the Cisco ME 3400EG-2CS-A, connect one end of the AC- power cord to the AC-power

connector on the switch, and connect the other end of the power cord to an AC-power outlet. (See

Figure 2-1.)

Figure 2-1 Cisco ME 3400EG-2CS-A Rear Panel

When the switch begins POST, the System LED blinks green, and the other LEDs remain solid green.

When the switch passes POST, the System LED becomes solid green. The other LEDs turn off and return

to their operating status. If the switch fails POST, the System LED is solid amber.

Note Contact Cisco Systems immediately if your switch fails POST.

Powering Off the Switch

After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a

wall, on a table, or on a shelf as described in the “Installing the Switch” section on page 2-5.

Rack-Mounting

To install the switch in a 19-inch, 23-inch, 24-inch rack, or a European Telecommunications Standards

Institute (ETSI) rack, follow these instructions. (The 24-inch racks and the ETSI racks require optional

mounting hardware.)

•Removing Screws from the Switch, page 2-6

•Attaching Brackets to the Switch, page 2-7

•Mounting in a Rack, page 2-13

Note Installing the switch in a 24-inch rack requires an optional bracket kit that is not included with the

switch. You can order a kit containing the 24-inch rack-mounting brackets and hardware from Cisco.

The kit part number is RCKMNT-1RU= (700-12398-XX).

Removing Screws from the Switch

First remove the screws in the switch chassis so that the mounting brackets can be attached (Figure 2-2).

Attaching Brackets to the Switch

The bracket orientation and the brackets that you use depend on whether you are attaching the brackets

for a 19-inch, 23-inch, 24-inch, or an ETSI rack. Figure 2-3 shows the standard types of mounting

brackets.

Figure 2-3 Rack-Mounting Brackets

•For 19-inch racks, use part number RCKMNT-19IN-1RU (700-08209-XX) on all except the

Cisco ME 3400EG-2CS-A, and see Figure 2-4 on page 2-8. For the

Cisco ME 3400EG-2CS-A, use RCKMNT-19-CMPCT= (700-23401-XX), and see Figure 2-5 on

page 2-9.

•For 23-inch racks, use part number RCKMNT-23IN-1RU (700-21646-XX) on all except the

Cisco ME 33400EG-2CS-A, and see Figure 2-6 on page 2-10. For the

Cisco ME 3400EG-2CS-A, use RCKMNT-23-CMPCT= (700-23402-01).
