Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product or included in the manual.

2. This product is intended to be used with a 3-wire grounding type plug — a plug that has a grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the grounding type plug by modifying the plug or using an adapter. Prior to installation, use an outlet tester or a voltmeter to check the AC receptacle for the presence of earth ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician has corrected the problem.

If a 3-wire grounding type power source is not available, consult a qualified electrician to determine another method of grounding the equipment.

3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to protect it from overheating, these slots and openings must not be blocked or covered.

4. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the power cord.

5. Do not attempt to service this product yourself, as it will void the warranty. Opening or removing covers may expose you to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel.

6. General purpose cables are described for use with this product. Special cables, which may be required by the regulatory inspection authority for the installation site, are the responsibility of the customer. To reduce the risk of

fire, use a UL Listed or CSA Certified, minimum No. 26 AWG (0.128 mm comparable cables certified for use in the country of installation.

7. When installed in the final configuration, the product must comply with the applicable Safety Standards and regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory agencies and inspection authorities to ensure compliance.

8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action prior to interconnecting the products.

9. In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:

— Never install telephone wiring during a lightning storm.

— Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

— Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the

network interface.

— Use caution when installing or modifying telephone lines.

— Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of

electric shock from lightning.

— Do not use the telephone to report a gas leak in the vicinity of the leak.

10. CLASS 1 LASER PRODUCT: This product has provisions for the customer to install a Class 1 laser transciever,

which provides optical coupling to the telecommunication network. Once a Class 1 laser product is installed, the equipment is to be considered to be a Class 1 Laser Product (Appareil à Laser de Classe 1). The customer is responsible for selecting and installing the laser transciever and for insuring that the Class 1 AEL (Allowable Emission Limit) per EN/IEC 60825 is not exceeded after the laser transponders have been installed. Do not install laser products whose class rating is greater than 1. Refer to all important safety instructions that accompanied the transciever prior to installation. Only laser Class 1 devices, certified for use in the country of installation by the cognizant agency are to be utilized in this product.

11. Input power to the ALARM relay interface (located on the front panel of the enclosure) must not exceed 30V rms or 60 VDC.

12. The equipment is intended for installation in a max. 65° C ambient temperature, in an environment that is free of dust and dirt.

) telecommunication cable, or

2600-A2-GN20-20 June 2004 B

13. The power supply cord for countries other than North America is to be a minimum H05 V V-F type, min. 0.75 mm2, 2-conductor and earth ground terminated in an IEC 320 connector on one end, and a plug which is certified for use in the country of installation at the other end.

14. Do not physically stack more than eight (8) 26x1 units high. Physical stability has not been evaluated for stacking higher than eight units, and any configuration greater than eight may result in an unstable (tip-over) condition. Ensure that the four (4) rubber feet supplied with the product have been installed on the bottom of each unit prior to stacking any 26x1 units on top of one another.

Consider the following before installing the BitStorm 2600 IP DSLAM:

 Installation Site

Your installation site should be well ventilated, clean, and free of environmental extremes.

 Installation Options

The BitStorm 2600 may be:

— Mounted with the included mounting brackets in a standard 19-inch

(483 mm) or 23 -inch (584 mm) rack (including both Bay Networks and Nortel 23-inch racks), or, with separately purchased mounting brackets, in a 21-inch (535 mm) ETSI rack. ETSI brackets are available from Paradyne. See Appendix B, Equipment List.

As many BitStorm 2600 units may be mounted in a standard rack as there are 1.75-inch (44.45 mm) spaces in the rack, so long as adequate cooling is provided.

— Mounted vertically against a wall.

The standard mounting brackets provided can be fastened to the base of the unit for wall mounting.

— Set on a shelf or desktop.

Up to five BitStorm 2600 units may be stacked on a shelf or desktop. Different models can be mixed in a stack.

 Power

The BitStorm 2600 operates from a 90 to 265 VAC, 47 to 63 Hz power source.

 Other Cabling

No cables are provided with the BitStorm 2600. See Table 1-2, Cable

Descriptions, to determine what cables you need to procure before

Mounting Brackets

Your BitStorm 2600 can be installed in a rack or on the wall using mounting brackets. Two brackets suitable for a 19-inch (483 mm ) rack (marked EIA-19) and two brackets suitable for a 23-inch (584 mm) Bay Networks or Nortel rack (marked with Paradyne Part Number 868-6282-0020) are shipped with the unit. Two brackets suitable for a 21-inch (535 mm) rack (marked ETSI) are available from Paradyne as a separate feature (see Appendix B, Equipment List ).

Rack-mounting brackets may also be used to attach the unit to a wall.

NOTE:

In this guide, the term rack refers to any rack, cabinet, frame, or bay suitable for mounting telecommunications equipment.

Installing the Brackets for Rack Mounting

Procedure

To install the mounting brackets for rack mounting:

1. Locate the black screw nearest the front panel on each side of the unit, as shown.

Two types of mounting screws are provided. Use:

 #10-32 mounting screws for rails with threaded screw holes

 #12-24 mounting screws and self-retaining nuts for rails with unthreaded

screw holes

Procedure

To install the BitStorm 2600 into a rack:

1. Determine where in the rack you will mount the BitStorm 2600. If your rack does not have threaded screw holes, slip self-retaining nuts onto the rails where the BitStorm 2600 will be fastened.
