The BIP provides the following basic functions and features: Eight power bus circuits, labeled A1 to A4 and B1 to B4. Each circuit is protected by an individual mid-trip circuit breaker. Sixteen compression type power input terminals (eight positive terminals, eight negative terminals). These terminals accept narrow-tongue 2-hole lugs. Narrow tongue lugs are defined as less than 0.5 inches, 1.12 cm wide. Eight D-sub type power output connectors. There is one connector per output. Each connector has a negative terminal (socket) and a positive terminal (pin). Field-replaceable Alarm Unit (AU). The AU receives and reports alarms from the protected equipment and from the BIP itself. It displays alarm status on the front console of the panel and outputs visual and audible alarm signals to the front office or remote device. Front console with alarm indicators. Included are CRITICAL (red), MAJOR (red), and MINOR (amber) LEDs. These alarms may be received from either the load equipment or the BIP itself. A smaller red LED (BIP Fault) indicates an internal fault in the BIP. Lamp Test and Alarm Cut Off (ACO) buttons on front console. Lamp Test button provides a means to test LEDs. ACO button provides ability to turn off major audible alarm signals. Swing-down front cover. Open cover provides access to user-accessible components of the panel including power connectors, alarm connectors, and the AU. Rack-mounting in three types of racks. As shipped, the rack mounts in a 21-inch (533.4 mm) rack per ETSI specifications. Alternate brackets provide mounting per EIA and FibreWorld standards (see Figure 10 on page 11.) Reliable grounding from chassis to office ground. Standard grounding is done using a compression type terminal block on the left side of the BIP chassis. Mesh-BN type grounding can be done using a bus bar (see Section 3.4 on Page 19). Input current of maximum 160 Amps input for the entire BIP, with a maximum of 40 Amps per individual circuit for NTK599BAE5 and 20 Amps per individual circuit for NTK599BGE5. Warning: At least one circuit must be powered on each side of the BIP (at least one A circuit and one B circuit). Otherwise, the BIP will generate a major alarm on power-up. Page 1

10 1.2 User-Accessible Components The BIP is a total front access panel. Figure 1 shows the user-accessible components of the panel. From bottom center in the figure, going clockwise, they are as follows: CIRCUIT BREAKER (8 X) POWER INPUT TERMINALS (16 X) POWER OUTPUT TERMINALS (8 X) ALARM INPUT AND OUTPUT CONNECTORS (NOT VISIBLE) A ALARM UNIT (AU) (NOT VISIBLE) FRONT COVER MOUNTING BRACKET (2 PLACES) Figure 1. User-Accessible Components Front Cover swings down to provide access to the components shown in the figure. Connector diagrams printed on the back of the cover identify the connectors and give pin designations. The front cover has a console on the its front side (not visible here). Alarm Unit (AU) collects alarms from protected equipment and from the BIP itself; indicates the alarms on the BIP front console. The AU also forwards alarm status to the front office or to a remote device. The AU is field-replaceable. Alarm Input and Output Connectors provide physical interfaces for alarm indications received from the load equipment (input) and forwarded to the front office or remote device (output). Both are D-sub type connectors. Circuit Breakers one for each output. These are individual, mid-trip circuit breakers. For specifications, see Section 1.14 on Page 11. Power Input Terminals for up to eight inputs (with two terminals per input), arranged from left to right into A1-A4 negative, A1-A4 positive, B1-B4 positive, B1-B4 negative. These are compression-type blocks with two studs per block for use with narrow tongue 2- hole lugs. Narrow tongue lugs are defined as less than 0.5 inches, 1.12 cm wide. Page 2

11 Power Output Terminals for up to eight power outputs. These are D-sub type, combo (2-position) connectors with a negative terminal (socket) and a positive terminal (pin). Mounting Brackets accommodate ETSI, EIA, or FibreWorld rack mounting. These components are described in more detail in the following topics. 1.3 Schematic Figure 2 is a BIP schematic showing the eight power circuits and indicating how the circuits are tied into the AU and front console.

12 1.4 Front Console The front console, located on the BIP front cover, provides alarm and status information and operation controls. Figure 3 shows the front console. Its items include the following: B Figure 3. Front Cover Indicators (NTK599BAE5 Shown) CRITICAL (Red), MAJOR (Red), AND MINOR (Amber) LEDs indicate alarms of the noted severity. An alarm is indicated when an alarm of the same type is received from the equipment protected by the panel. Alarm events in the AU and BIP are also indicated using the same LEDs, as indicated in Table 1. ACO (Alarm Cut Off) Button can be used to turn off the major audible alarm forwarding signals from the AU. Lamp Test Button Can be used to test all of the front console LEDs. When the button is pressed, all of the LEDs illuminate. BIP Fault Lights when the BIP has an internal fault. Alarms in the BIP result from loss of input power, a tripped breaker, or a failed fuse in the AU. For a summary of how these indicators work with respect to one another, refer to Table 1.

13 1.5 Alarm Unit (AU) The Alarm Unit (AU) is a electronic module factory-installed in a compartment in the lower central area of the BIP on the front side. The AU collects bay level alarms from the load equipment and from the BIP itself. It reports any alarm condition on the BIP front console. The alarm condition reported may be critical, major, or minor, per standard industry definitions. For each of these states, there is an LED on the BIP front console. The AU connects to the back side of the front cover by way of an external cable. The AU provides alarm indications for forwarding to the front office or to a remote device. A forwarded alarm indication consists of separate visual and audible signals transmitted through different pins of the AU output connector. The AU is field-replaceable from the front side of the BIP. A slot screwdriver is required to remove or install the AU. Figure 4 is a schematic of the main components of the AU.

Alarm Unit Schematic AU Input and Input Connector The 9-pin input interface from the load equipment to the AU provides direct connections to six normally closed (NC) circuits that switch to an open state when an alarm exists. These six circuits are assigned based on the three levels of alarm severity (critical, major, and minor) plus the two types of indications (audible and visual) forwarded for each alarm to the front office or remote device. Page 5

14 The alarm input interface is Telecommunications Network Voltage (TNV) 2 for 60V systems and Safety Extra Low Voltage (SELV) for 48V systems. The incoming alarm signals (contacts, connectors, and wiring) must be capable of carrying up to 2 Amps current. The input connector is a 9-pin D-sub receptor located on the front side of the AU. Figure 5 shows the pin configuration. Table 2 gives the pin designations. For an indication of how the received alarms affect the BIP front console LEDs, refer to Table 1 on Page A Figure 5.

The output interface also reports the state of the BIP and the AU using the same alarm states. For each single pin on the input interface, three pins are used on the output interface, providing the standard NO-NC-COM configuration of contacts for use by the front office device. The output circuits are normally closed. An open circuit indicates an alarm exists. Figure 6 shows the output connector. Table 3 gives the pin designations. An adapter connector is available that, when plugged into the output connector, provides a wire wrap pin array with the same pin designations A Figure 6.

The voltage output from a given circuit at any time corresponds to the voltage input to that circuit. The maximum voltage drop between any input terminal and any output terminal is 0.35 V at breaker rated amperage. 1.7 Power Input Connections Power feeds for the eight BIP circuits are connected on the front side of the panel using twohole compression lugs The panel accommodates either straight lugs with wires pointing up or 90 o -angle lugs with wires pointing backward. For each power input, there is one negative (L ) and one positive (L+) terminal, but not side by side. The terminals are arranged as follows (from left front to right front): A1 to A4 negative, A1 to A4 positive, B1 to B4 positive, and B1 to B4 negative. This arrangement allows all eight positive terminals to be grounded together as required for ETSI Mesh-BN system bonding topologies. This is done using an 8x bus bar with a screw-in connection to an unremovable grounding point on the BIP chassis (see Figure 18 on page 20). Each individual terminal has two #10 (0.25-inch, 1.12 cm) studs mounted on inch (1.59 cm) centers. The terminals accept narrow-tongue lugs with a maximum lug width of 0.5 inches (1.12 cm). Up to #2 AWG or 35 mm 2 copper wire can be used. In selecting the copper wire size to be used for power input, consider the allowable ampacity as defined by local practice and the National Electrical Code (refer to Appendix A). Page 7

16 2x (negative terminal) bus bars can be used in combination with 4x (positive terminal bus bars) to reconfigure the power input to use four power feeds per BIP instead of the standard eight power feeds. (In either case, there are eight power outputs.) 8x bus bars can be used for grounding across the eight positive terminals, as required for ETSI Mesh-BN system bonding topologies. Figure 7 shows the input configurations. Note: When eight input feeds are used, use of the 4x bus bar (as shown in Figure 7) is optional. 4 INPUT FEEDERS PER SIDE 2 INPUT FEEDERS PER SIDE ETSI, 4 INPUT FEEDERS PER SIDE ETSI, 2 INPUT FEEDERS PER SIDE "L-" (B4) "L-" (B4) "L-" (B4) "L-" (B4) "L-" (B3) "L-" (B3) "L-" (B3) "L-" (B3) "L-" (B2) "L-" (B2) "L-" (B2) "L-" (B2) "L-" (B1) "L-" (B1) "L-" (B1) "L-" (B1) "L+" (B4) "L+" (B4) "L+" (B4) "L+" (B4) "L+" (B3) "L+" (B3) "L+" (B3) "L+" (B3) "L+" (B2) "L+" (B2) "L+" (B2) "L+" (B2) "L+" (B1) "L+" (B1) "L+" (B1) "L+" (B1) OPTIONAL BONDED TO FG BONDED TO FG "L+" (A4) "L+" (A4) "L+" (A4) "L+" (A4) "L+" (A3) "L+" (A3) "L+" (A3) "L+" (A3) "L+" (A2) "L+" (A2) "L+" (A2) "L+" (A2) "L+" (A1) "L+" (A1) "L+" (A1) "L+" (A1) "L-" (A4) "L-" (A4) "L-" (A4) "L-" (A4) "L-" (A3) "L-" (A3) "L-" (A3) "L-" (A3) "L-" (A2) "L-" (A2) "L-" (A2) "L-" (A2) "L-" (A1) "L-" (A1) "L-" (A1) "L-" (A1) = EXTERNAL JUMPER A Figure 7. Input Feed Configurations 1.8 Power Input Current The BIP accommodates a maximum input current of 160 Amps (for the entire panel). At least one circuit on either side of the panel (at least one A and one B circuit) must be used. If one side only (only A or B side) receives current, the BIP will generate a major alarm. Page 8

17 Two negative input terminals can be linked together using a 2x bus bar. When this is done, the current into the linked inputs is distributed equally between the linked circuits. For example, if 30 Amps is applied to linked circuits A1 (L ) and A2 (L ), the A1 and A2 circuits each wind up with 15 Amps current. 1.9 Ground Connections A compression type grounding block is provided on the left front side of the BIP for attaching a grounding cable to Framework Ground (a.k.a. Protective Earth). The PEM nuts accept a #10, two-hole compression lug with 5/8 inch (1.59 cm) hole spacing. The PEM nuts are suitable for terminating #6 AWG (or equivalent size) wire or a 35 mm 2 (ETSI applications) conductor. An 8x bus bar is available for BR grounding across all eight positive power input terminals in the upper front center side of the BIP (see Figure 7 on page 8). The 8x bus bar fits on the 2-stud compression type input power terminals. It has a screw-down grounding tab used to fasten the bus bar to an unremovable grounding point on the BIP chassis Power Output Connections Output power is supplied to the load equipment through eight D-sub connectors located on the front of the panel. These connectors are labeled A1 to A4 and B1 to B4 corresponding to the power input terminal blocks. Each connector on the panel has one negative (L ) position (socket) and one positive (L+) position (pin). See Figure 8. In addition, each connector has two standoffs for housing screws. For reference purposes, the connector is A (for example, Conec 302W2CSXX99A10X). Table 4 gives pin designations. These connectors accept copper wire in sizes up to #8 AWG. In selecting wire size to be used for power output, consider the allowable ampacity as defined by local practice and the National Electrical Code (refer to Appendix A). SOCKET PIN L- L R Figure 8.

18 1.11 Circuit Breakers The BIP provides eight power circuits, each protected with an individual circuit breaker. The circuit breakers are of the mid-trip type, with an electronically activated middle position in addition to the manually activated ON and OFF positions. The middle position is activated automatically by an electrical overload. When in the middle position, the circuit breaker interrupts power supplied to the protected equipment while allowing an alarm signal to be forwarded. Current in the eight circuits together cannot exceed 160 Amps, the panel maximum Dimensions Figure 9 shows BIP dimensions IN. (43.5 CM) IN. (28.0 CM) 3.94 IN.

21 2 BEFORE STARTING INSTALLATION This section provides general installation recommendations and unpacking and inspection procedures. Also, this section lists the tools and materials required for installation. 2.1 General Installation Recommendations The Ciena Breaker Interface Panel (BIP) must be installed in a restricted access location in accordance with Articles , , and of the National Electrical Code, ANSI/ NPFA 70. Mount the BIP in the uppermost area of the rack to reduce the exposure of the power wiring. Route ground, input power, output power, and alarm cables to the BIP according to local practice and procedures. After routing cables, secure them to the rack or to any cable management devices that are in use. When mounting the BIP in the rack, make sure mechanical loading is even to avoid a hazardous condition. The rack shall be capable of supporting the combined weight of all equipment. If the BIP is installed in a closed or multi-rack assembly, the operating temperature of the rack environment may exceed the ambient temperature. Be sure to install the BIP in an environment compatible with the maximum rated ambient temperature. Maintain one rack unit clearance for the bottom and top of the BIP to allow for adequate cooling air flow. Install protective covers on the front side of the power input terminals after all wiring connections are made and tests completed. Do not apply power to the BIP until all wiring and tests are completed. 2.2 Unpacking and Inspection Before starting the installation, always open the shipping boxes and verify that all parts have been received and that no shipping damage has occurred. Check the BIP for broken or missing parts. If there is any damage, contact Ciena (refer to Section 6). 2.3 Installation Tools Required The following tools are required to install the BIP: Screwdrivers (both Phillips and flatblade) Torque wrench calibrated in pound-force inches or Newton meters 3/8-inch and 7/16-inch sockets (for torque wrench) Wire cutter Wire stripper Compression lug crimper Wire-wrap tool Multimeter Heat gun Page 13

22 2.4 Materials Required The following materials are required to install the fuse panel: Insulated copper wire for input and output power wires (see Appendix A); 2-hole compression lugs for terminating power input wires and grounding wires (see Section 1.14, Specifications, on page 11). 3 INSTALLATION This section tells how to pre-test and install the BIP. 3.1 Pre-Installation Testing Each panel is thoroughly tested at the Ciena factory before being shipped. However, before the panel is installed, continuity tests should be performed to verify that no internal damage has occurred during shipping and handling. Using a multimeter that is set to perform a continuity check, perform the following tests. Test 1: Input Battery to Input Return Use the following procedure: 1. Turn the circuit breakers to the ON position. 2. Connect one test probe to the A-1 (L ) input power terminal and the other test probe to the A-1 (L+) input power terminal, as shown in Figure 11. TEST THAT NO CONTINUITY EXISTS BETWEEN NEGATIVE AND POSITIVE INPUT TERMINALS FOR EACH POWER CIRCUIT (A1 - A4, B1 - B4) A1 (L-) A1 (L+) A Figure 11. Test 1: Input Battery to Input Return Page 14

23 3. Verify that no continuity exists between the A-1 (L ) and the A-1 (L+) terminals. 4. Repeat the test procedure for each remaining (L )/(L+) pair for the remaining terminals: A2 (L ) and A-2 (L+), A3 (L ) and A-3 (L+), and so on, until the circuits have been tested. Test 2: Input Battery to Output Battery Use the following procedure (Figure 12): Note: Each D-sub type power output connector has one socket and one pin. The socket is the negative (L ) contact. 1. Turn the circuit breakers to the ON position. 2. Connect one test probe to the A-1 (L ) power input terminal and insert the other test probe in the socket on the A-1 power output connector, as shown in Figure 12.

30 3.6 Connecting Output Output power is supplied to the load equipment through D-sub connectors labeled A1 to A4 and B1 to B4 on the right front side of the panel. Each connector has a socket (negative terminal) and a pin (positive terminal). For a diagram, refer to Figure 4 on page 9. The output power terminals accept copper wire in sizes ranging from #8 to #16 AWG. In selecting wire size, follow local code and refer to Appendix A. 1. Obtain AWG wire of the specified size and connect it to the specified connector types if the connectors are not already prepared. Note: In most cases, the connectors will be standard types already wired to the load equipment. If additional specifications are required for the output power connectors, refer to Section 1.10, Power Output Connections, on page Connect the connectors to the BIP power output terminals (Figure 21). POWER OUTPUT TERMINALS (8 PLACES) A Figure 21. Power Output Terminals 3. Tighten the connector housing screws to 4 pound force-inches (0.5 Newton-meters) of torque. 4. Route the free end of each output power wire to the equipment for connection. 3.7 Connecting Input The power input terminals accept #10 two-hole compression lugs with 0.25 inch holes on inch centers. The tongues must be narrow gauge with a maximum width of 0.5 inches (1.12 cm). Nuts with captive washers are provided to secure the lugs to the terminal block. The lugs may be either straight or angled (90 o ), providing for power wire entry from either above or behind the BIP, respectively. Up to #2 AWG or 35 mm 2 copper wire can be used. In selecting the copper wire size to be used for power input, consider the allowable ampacity as defined by local practice and the National Electrical Code (refer to Appendix A). Page 22

31 The standard power input configuration uses eight power feeds, each with a negative lug and a positive lug. This configuration uses all 16 terminals, with one lug per terminal. An alternative arrangement uses 2x and 4x bus bars (provided) to configure the BIP for four power feeds. The four 2x bus bars are installed on the eight (L ) terminals; the two 4x bus bars are installed on the eight (L+) terminals. For illustrations of these configurations, see the following procedures Standard Configuration To connect input power wires in a standard condiguration, use the following procedure: 1. Obtain 16 lengths of copper wire for use as the input power wires. 2. Strip back 7/8 inches of insulation from one end of each wire. 3. Slide a 2-inch length of heat shrink insulation over the end of each wire. 4. Terminate one end of each wire with 2-hole lugs (customer provided; requires crimper). The lugs may be either straight (top entry, Figure 22) or right-angled (rear entry, Figure 23).

34 4 POWER-UP CHECK Use the following procedure to check that the BIP for correct operation: 1. Verify that the input power cables are connected to the correct terminals. 2. Verify that the circuit breakers for all circuits are ON. 3. Apply power to the BIP. 4. Verify that the Power OK (green) LEDs on the front console are lit. 5. Verify that the BIP Fault (red) LED on the front console is not lit. 6. Verify that the CRITICAL (red), MAJOR (red), and MINOR (amber) LEDs on the front console are not lit. 7. Depress the Lamp Test button and verify that all the LEDs are working correctly (they should all illuminate). 8. Using a multimeter set to measure dc voltage, measure the voltage between each input return (L+) terminal and chassis ground. The voltage level should be less than 2.0 Vdc. If the voltage on the (L+) terminal is much higher, and reads out in the 40 to 60 Vdc range, the lugs are probably reversed. If this appears to be true, power down the panel. Disconnect the (L+) and (L ) lugs and switch them around. Power up the panel and check again to verify that the higher voltage is on the (L ) lug. 9. If any problem occurs that cannot be resolved, consult Ciena for technical assistance. 5 MAINTENANCE This section provides maintenance procedures for the BIP. 5.1 Performing a Routine Inspection 1. Inspect the panel for damage to the circuit breakers and for damaged or broken wires at the power and external alarm connections. 2. If excessive dirt is found during the inspection, brush or wipe dust from the panel with a soft bristle brush or soft cloth. 3. Depress the Lamp Test button on the front console; verify that all LEDs illuminate. Page 26
