2.3 General Requirements

The sections that follow outline the mandatory regulations that govern the installation

and operation of the 7210 SAS-R12. The information in this section also describes

instructions and information related to overall conformance with the mandatory

regulations. You must adhere to these instructions so that your system meets

regulatory requirements.

2.3.1 Dangers and Warnings

You must comply with the general safety precautions and product requirements

described below during site preparation and equipment installation. Specific

precautions and requirements are contained in the individual chapters in this guide.

Danger:

• The 7210 SAS-R12 uses a fiber-optic communication method and is a Class

1 laser product. Additionally, there are no user-serviceable parts in the

7210 SAS-R12 chassis. Installation and servicing of the system must be

done only by trained service personnel familiar with potential electrical,

mechanical, and laser radiation hazard.

• Before working on equipment that is connected to power, remove jewelry,

such as rings, necklaces, and watches. When metal objects are in contact

with power and ground, serious burns can occur or the objects can be

welded to the terminals.

• CLASS 1 LASER PRODUCT

• APPAREIL À LASER DE CLASSE 1

• DISCONNECT BOTH POWER FEEDS BEFORE INSTALLATION AND

SERVICING

• DÉBRANCHER L’ALIMENTATION LES 2 SOURCES DC AVANT

Warning: The compliance and long-term reliability of the 7210 SAS-R12 are wholly

dependent on using the product within the environmental limits and restrictions described in

this document.

2.3.2 Anti-static Measures

Figure 1 shows the ESD awareness label used on Alcatel-Lucent products to alert

personnel to the presence of ESD-sensitive devices in the product. This icon and

associated text provide special information relating to ESD-sensitive activities or

situations. The ESD precautions that follow must be taken whenever this symbol is

present on the product.

Figure 1 ESD Awareness Label

The risk of damage to an ESD-sensitive device is reduced considerably after

assembly in a circuit designed to protect sensitive components; however, the

following basic precautions should be taken to reduce ESD to harmless levels.

• Handle all units as if they contained ESD-sensitive devices unless they are

known not to contain ESD-sensitive parts.

• Wear an anti-static ESD strap on your wrist or heel prior to and while touching

or handling units containing ESD-sensitive devices.

• For surfaces with resistance to ground in excess of 100 MΩ, such as ordinary

tile, either cover them with properly grounded static dissipative runners or

wax them with a static dissipative wax.

• Store (even temporarily), pack, and ship units in anti-static bags or

containers.

Warning:

• ESD damage can occur if components are mishandled. The chassis and

equipment rack must be properly grounded. A typical grounding point is one

of the ground studs on the chassis or a properly grounded rack or work

bench.

• Always wear an ESD-preventive wrist or ankle strap connected to a nearby

ground point that is connected to the site grounding point when working on

the

chassis or the 100W High Voltage Power Supply.

Edition: 06 3HE 10320 AAAA TQZZA 19

• Do not handle units and components unnecessarily. Use the plastic faceplate

to handle circuit boards.

• Do not use synthetic bristled brushes or acid brushes to clean units.

• Handle failed units with the same precautions as working units.

2.3.2.1 Grounding

When a 7210 SAS-R12 chassis is properly installed in a grounded equipment rack,

the rack provides ESD grounding for the chassis. Before a 7210 SAS-R12 chassis is

installed, connect the ESD wrist strap to a grounded rack or other ground point. After

the chassis is installed in a grounded rack or cabinet, connect the anti-static wrist

strap to the ESD strap ground point on the ground stud that is located on the front of

the chassis and identified by the wrist strap label.

2.3.3 Equipment Interconnection Points

2.3.3.1 SELV/ES1

The following interconnection points on all 7210 SAS-R12 chassis are SELV or ES1

connections:

• SONET/SDH ports

• Gigabit Ethernet ports

• Management port

• Console port

• DC battery input (when less than 60 VDC)

Warning: Only connect like circuits: SELV to SELV, TNV-2 to TNV-2, as defined in IEC

60950-1.

2.3.3.2 TNV-2/ES2

The following interconnection points on all 7210 SAS-R12 chassis are TNV-2 or ES2

connections.

• DC battery input (from 60 VDC up to 80 VDC)

2.3.4 Prevention of Access

The 7210 SAS-R12 and 100W High Voltage Power Supply must be accessible only

to authorized, trained service personnel. Install this apparatus in a restricted access

location or similar environment to prevent unauthorized access.

2.3.5 Environmental Requirements for Installation

For information on the environmental requirements for installing the 7210 SAS-R12,

see section 9.

2.3.6 Laser Interface

The 7210 SAS-R12 uses a fiber-optic communications method and is an FDA and

IEC Class 1 Laser product. Only trained service personnel thoroughly familiar with

laser radiation hazards should install or remove the fiber-optic cables in this system.

2.3.7 Protective Safety Ground (Earth)

The cable used for safety ground should be at least the same gauge as the supply

conductors, green, or green and yellow, in color, and of sufficient length to connect

the building earth point to the chassis ground connection (refer to section 4.5.1 for

specific instructions on connecting the chassis ground).
