Safety Information

The following statements are warnings or safety guidelines. A warning means danger. You are in a situation that could cause bodily injury. Before working on equipment, be aware of the hazards involved with electrical circuitry and standard safety practices to prevent accidents.

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.
This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Do not work on the system or connect or disconnect cables during periods of lightning activity.
The device is designed to work with TN power systems.
Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.
Ultimate disposal of this product should be handled according to all national laws and regulations.
Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.
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.
The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.
Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI card when no cable is connected. Avoid exposure and do not stare into open apertures. Following is an example of the warning label that appears on the product:
Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned off.
To prevent problems with the E1 interface and to reduce the potential for injury, jumper J2 should be configured by trained service personnel only. For either impedance option, a jumper installed at J2 bypasses the AC-decoupling capacitor to ground, thereby coupling the interface directly to AC. This setting could pose a risk of severe injury. By default and for safety, J2 is configured with no ground.
Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.
The DC unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock, and key, or other means of security, and is controlled by the authority responsible for the location.
Only trained and qualified personnel should be allowed to install or replace this equipment.
Read the installation instructions before you connect the system to its power source.
When installing the unit, the ground connection must always be made first and disconnected last.
The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last.
After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position.
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.
The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by nonremovable, connect-one-time-only lug) must be made only by PTO staff or suitably trained engineers.

ISDN Safety and Compliance Conditions

This section contains safety and agency compliance information.

BRI Network Processor Module Independent of Host

The Basic Rate Interface (BRI) network processor module for the Cisco 4000 series is a processor/interface card assembly for use within a range of data communication (gateway and router) chassis supplied by Cisco Systems throughout Europe. The BRI module is a self-contained product that provides all of the hardware necessary to allow connection of the Cisco 4000 series chassis to four or eight Basic Access Integrated Services Digital Networks (ISDNs) each at the S-reference point. The ISDN usage is restricted to point-to-point mode only.

The BRI network processor module must have a dedicated S-bus connection for each of its ISDN ports. The BRI module cannot share any of its S-bus connections with other terminal equipment; therefore, no other terminals should be connected to the same S-bus as a BRI module connection.

The four or eight ISDN connections must be made to network connection points that are provided by one network vendor or public telecom operator (PTO) to ensure that common network timing exists between the ISDN ports used. Failure to observe this point may result in lost (nonrecoverable) data packets because of timing slips.

The BRI network processor module is fully transportable between compatible host chassis. The choice of each compatible chassis has no impact on the capabilities, functionality, or performance of the BRI network processor module.

The BRI network processor module consists of the following subassemblies:

BRI network processor module mother card (part number 73-1219)
1 BRI adapter interface card (part number 73-1220)
BRI-ISDN (point-to-point use) Software Version 1.0

The BRI network processor module provides users of compatible host router or bridge chassis with a high-speed throughput, point-to-point connection that can be set up over the digital telecommunication network ISDN.

BRI Module Installation Requirements---Special Considerations

Observe the following considerations during the installation of a Cisco 4000 series router with ISDN interfaces.

ISDN, Type of Connection

Where your PTO has provided you with ISDN modular sockets, the BRI module can be plugged in to make the connection. Connections should only be made to a BRI module properly installed within the host chassis.

In certain countries, the BRI network processor module must be hardwired permanently to the S-reference connection point. This is accommodated for by the use of a connect one-time-only, nonremovable plug (an RJ-45 with the latch tab removed).

ISDN Connection, Safety Warning

Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)--provided equipment or connection hardware. Any hardwired connection (other than by nonremovable, connect-one-time-only lug) must be made only by PTO staff or suitably trained engineers.

The BRI network processor module is approved only for installation in a host chassis and with host attachments, which are either type approved for such apparatus, or covered by a general approval.

Maintaining Safe Installation Distances

Except at the edge connector that plugs into the host chassis expansion slot, clearance and creepage distances of X millimeters (mm) and Y mm as listed in Table 1 must be maintained between the cards and other parts of the host including any other expansion cards fitted.

Table 1 : Creepage and Clearance Distances Based on Voltage

Voltage¹ (Vrms or VDC)² Creepage (Y mm)³ Clearance (X mm)

Up to 50 2.4 (3.8) 2.0

Up to 125 3.0 (4.8) 2.6

Up to 250 5.0 (8.0) 4.0

Up to 300 6.4 (10.0) 4.0

¹ Refers to the voltage used or generated by other parts of the host or expansion card.
² Vrms = root mean square voltage; VDC = volts direct current.
³ The creepage distances not in parentheses apply when the equipment is installed in a normal office environment. The larger dimensions, in parentheses, must be applied when the equipment is installed in an environment in which dust and other types of pollution could conduct electricity because of the effects of dampness and condensation. This applies to locations subject to high humidity.

Voltage¹ (Vrms or VDC)²	Creepage (Y mm)³	Clearance (X mm)
Up to 50	2.4 (3.8)	2.0
Up to 125	3.0 (4.8)	2.6
Up to 250	5.0 (8.0)	4.0
Up to 300	6.4 (10.0)	4.0

Note the following points in Table 1:

Clearance distances are defined as the minimum distance measured in air between two points (i.e., line of sight)
Creepage distances are defined as the minimum distance measured across the surface of an insulator between two points (i.e., following the contour of the insulator)

Creepage and clearance distances are measured between adjacent parts as shown in Figure 1.

Figure 1 : Creepage and Clearance Distances between BRI Module and Components

Note that in Figure 1 x indicates the clearance distances between cards and adjacent cards and components, and y shows the creepage path across the surface of an insulator and between the two points indicated by x.

Host Power Supply Requirements

The power requirements of the BRI network processor module are as follows:

+5 VDC/2.5 mA
+12 VDC/100 mA
--12 VDC/100 mA

Ensure that the power drawn by the apparatus together with the power drawn by any auxiliary apparatus lies within the rating of the host chassis power supply.

Additional Safety Information

The BRI network processor modules contain safety extra-low voltage (SELV) circuitry. Ensure that attachments at the interconnection ports of the apparatus are also SELV circuits. (SELV circuits are so designed and protected that, under both normal conditions and a likely fault condition, the current that can be drawn is not hazardous.)

Always disconnect the host chassis from the power supply before removing any covers.

Always disconnect the host chassis from any analog telephone circuits or Basic Access ISDN (where applicable) before removing any covers.

Failure to install the BRI modules in accordance with these instructions will invalidate any telecommunication terminal equipment type approval(s).

If you have any doubt as to how to safely install a Cisco 4000 series BRI module correctly within a host chassis, seek advice from a qualified telecommunications engineer.
