Introduction

This chapter describes how to install a Cisco SCE8000 chassis.

Warning

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

Statement 1030

Warning

There is the danger of explosion if the battery is replaced incorrectly. The battery is not a

user-serviceable part.

Statement 1015

Warning

Class 1 laser product.

Statement 1008

Warning

Because invisible laser radiation may be emitted from the aperture of the port when no cable is

connected, avoid exposure to laser radiation and do not stare into open apertures.

Statement 1056

Warning

Blank faceplates and cover 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, faceplates, front covers, and rear covers are in place.

Statement 1029

Note Before you install, operate, or service the system, read the Regulatory Compliance and Safety

Information for the Cisco SCE8000 Platform. This guide contains important safety information you

should know before working with the system.

Preparing for Installation

Caution Before working on a chassis or working near power supplies, unplug the power cord on AC units;

disconnect the power at the circuit breaker on DC units.

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

device.

Note 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.

Safety

Warning

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

Note 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.

Note This product requires short-circuit (overcurrent) protection, to be provided as part of the building

installation. Install only in accordance with national and local wiring regulations.

Chapter 4 Installing the Cisco SCE8000 Chassis

Site Requirements

This section provides site power requirements for the Cisco SCE8000 chassis. Verify the site power

before installation.

•Preventing Electrostatic Discharge Damage, page 4-3

•Environmental Requirements, page 4-3

•Power Requirements, page 4-4

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are

improperly handled, results in complete or intermittent failures. Port adapters and blades consist of

printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and

connectors are integral components of the carrier. Although the metal carrier helps to protect the board

from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

•Connect the equipment end of the strap to an unfinished chassis surface.

•When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental

removal, provide proper grounding for the system, and help to ensure that bus connectors are

properly seated.

•When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

•Place a removed component board-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding

container.

•Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

•Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohm (Mohm).

Environmental Requirements

Ensure adequate spacing between racks using the information in the following table. Keep all of the

vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust

ports of other equipment. Table 4-1 lists the chassis airflow requirements, and Table 4-2 lists the

Cisco SCE 8000 environmental requirements.

Site Requirements

Power Requirements

Warning

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

Follow these requirements when preparing your site for the Cisco SCE8000 installation:

•The redundant power configuration provides a second, identical power supply to ensure that power

to the chassis continues uninterrupted if one power supply fails or input power on one line fails.

•Connect each of the two power supplies to a separate input power source. If you fail to do this, your

system might be susceptible to total power failure because of a fault in the external wiring or a

tripped circuit breaker.

•To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the

power supplies is within the current ratings of the wiring and breakers.

•In some systems, you might use an uninterruptible power supply (UPS) to protect against power

failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can

become unstable with systems like the Cisco SCE8000, which can have substantial current draw

fluctuations because of bursty data traffic patterns.

Power Connection Guidelines

This section provides the guidelines for connecting the Cisco SCE8000 AC and DC power supplies to

the site power source.

•AC-Powered Systems, page 4-5

•DC-Powered Systems, page 4-11

•Site Planning Checklist, page 4-13

AC-Powered Systems

•Each chassis power supply should have its own dedicated branch circuit.

•Circuits must be protected by a dedicated two-pole circuit breaker.

–

For North America, the circuit breaker should be rated at 20A.

–

For everywhere else, the circuit breaker should be sized according to the power supply input

rating and local or national code requirements.

•AC power receptacles used to plug in the chassis must be the grounding type. The grounding

conductors that connect to the receptacles should connect to protective earth ground at the service

equipment.

Warning

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.

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

device.

Note This product requires short-circuit (overcurrent) protection, to be provided as part of the building

installation. Install only in accordance with national and local wiring regulations.
