Introduction 1 What is the 8820 Broadband Access Concentrator? The 8820 Broadband Access Concentrator (BAC), which can be installed at the Network Service Provider (NSP) location, provides high-speed Internet or intranet access. The BAC is a 20-slot chassis with integral power distribution and conditioning, as well as alarm, cooling, and interface subsystems designed to house up to 18 Digital Subscriber Line (DSL) port cards.
1. Introduction The following illustration shows a high-level view of a typical configuration for an 8820 BAC.
1. Introduction Line cards Provide a processor and an Ethernet or ATM interface to the NSP. The processor controls the modems and forwards the packet traffic to and from the Ethernet, ATM and DSL interfaces. Models include: — 8303 24-port Integrated Services Digital Network (ISDN) Digital Subscriber Line (IDSL) card that interoperates with the 6301 and 6302 IDSL Routers. — 8304 24-port Packet IDSL 2B1Q card with ATM uplink that interoperates with the 6301 and 6302 IDSL Routers.
1. Introduction RADSL, ReachDSL, IDSL, SDSL, ATM SDSL, ATM ADSL, TDM SDSL, and TDM SHDSL cards are generically referred to as line cards in this document. Table 1-1 shows which line cards can be used with the different SCP card, MCP, and SCM configurations. Table 1-1.
1. Introduction Major/Minor Alarm Contacts for CO Alarm Requirements The BAC provides two sets of dry contacts via the System Interface Module (SIM), accessible through an 8-pin modular jack, for connection to a CO alarm system. LED Indicators for Power and Fan Status and Major and Minor Alarms Five LEDs on the front panel of the BAC indicate the status of important functions (see LEDs in Chapter 6, Troubleshooting).
1.
Installation 2 Preinstallation Considerations Consider the following before installing the 8820 BAC: Installation Site Your installation site should be well ventilated, clean, and free of environmental extremes. There should be 2 to 3 feet (61 to 91.5 cm) of clearance at the front of the rack in which the chassis is to be installed to allow access for the installation of the chassis, circuit cards, and cables.
2. Installation Cabling Use only CAT3 or greater twisted-pair network connection cables for DSL connections and interface patch cabling. Untwisted analog cables of any length anywhere in the loop substantially contribute to crosstalk and reduced loop reach. If there is adequate maintenance space at the rear of the rack, mount the chassis on the rack before installing cables. If not, install the rear-mounted network cables on the chassis before mounting the chassis on the rack.

2. Installation Mounting Configurations The 8820 BAC comes equipped with mounting brackets to support installation in 19-inch (48.3 cm) Electronic Industries Association (EIA)-type or 23-inch (58.4 cm) NEBS-type racks. Installation of the 8820 chassis in a European Telecommunication Standards Institute (ETSI)-type rack requires a different set of custom mounting brackets. The following figure depicts an example of a chassis mounting configuration with three chassis in a rack.
2. Installation Chassis Installation You will need a Phillips screwdriver to install the 8820 BAC into a commercial EIA-standard 19- or 23-inch rack. For both the 19- and 23-inch wide rack, the chassis can be installed in one of four depth positions: front flush-mount, 1-inch (2.54 cm) setback, 3-inch (7.62 cm) setback, or 5-inch (12.7 cm) setback. The chassis is shipped for a 19-inch rack with a 1-inch setback. The rack that the chassis will be installed in may or may not have threaded screw holes.
2. Installation Changing the Setback Position of the Mounting Brackets The setback position of the mounting brackets may be changed from the shipped 1-inch setback position to the flush, 3-inch, or 5-inch setback positions by removing the mounting brackets’ three screws, repositioning the mounting brackets, then reinstalling the three screws. Procedure To change the position of the mounting brackets: 1. Remove the screws (three on each side) that hold the mounting brackets to the chassis. 2.
2. Installation Installation into a 19-Inch or 23-Inch Rack Front Rail Screw Keyhole Front of 19-inch Rack 00-15324a-02 Procedure To install the chassis in a rack: 1. Determine the preferred placement of the chassis in the rack. The chassis is 24.5 inches high (14U, where 1U is 1.75 inches or 44.45 cm). The center of the first mounting holes on each side of the chassis is 1.484 inches (3.77 cm) from the top of the chassis.
2. Installation Installation into a Rack without Threaded Screw Holes Front Rail Self-retaining Nut Screw Keyhole Front of 19-inch Rack 02-15324b-02 Procedure To install the chassis in a rack that does not have threaded screw holes: 1. Determine the preferred placement of the chassis in the rack. The chassis is 24.5 inches (62.2 cm) high. The top mounting hole is 1.484 inches (3.77 cm) from the top of the chassis. Mark the appropriate locations for the machine screws on the rack. 2.
2. Installation Installing the Air Filter The BAC is shipped with an air filter. The air filter prevents dust from entering the chassis. If this air filter is not already installed in the chassis, use the installation procedure below. Once it is installed, you should inspect and replace the air filter at least once a year. A harsh environment will require more frequent filter changes. To purchase a replacement air filter, contact your sales representative. Procedure To install the air filter: 1.
2. Installation Connecting Power The BAC is furnished with two internally mounted circuit breakers for redundant power (PWR A and PWR B). Two separate, unswitched, individually fused power sources, each capable of safely handling this load, are required for power redundancy. The chassis provides either front or rear power access connections. Rear power access is recommended due to ease of installation.
2. Installation Front Power Access Front power access is made via two PEMs which are located in the front, lower left side of the chassis. PEM A is located on the left, while PEM B is on the right.
2. Installation 4. Fasten the #8 AWG wires, with their ring tongue terminals properly installed (see Step 1), to the power taps using the M4 Phillips-head screws. — Connect the negative wire to the power tap on the right (48V NEG is printed on the front of the PEM’s faceplate). — Connect the return or positive wire to the power tap on the left (48V RTN is printed on the front of the faceplate).
2. Installation Rear Power Access ! WARNING: — It is recommended that the following procedure be performed by a qualified electrician. — Never remove the metal cover(s) without first ensuring that the power has been disconnected at the source. — When installing or servicing rear access power connections, never remove both metal covers at the same time to avoid exposure to 48 or 60 VDC potentials. M4 Phillips-head Screws – 48V PWR A RTN RTN PWR B – 48V CAUTION: USE NO.
2. Installation Procedure To connect power to the rear of the chassis: 1. Apply the supplied compression-type ring tongue terminals to the #8 AWG power wires. Use the Molex MagnaCrimp Hand Tool (Part No. MCT-8200). 2. Remove the left or right metal cover on the lower, rear of the chassis. The left metal cover is for PWR B power connections, and the right metal cover is for PWR A power connections.
2. Installation Insertion or Removal of the PEMs ! WARNING: If both PEMs are being supplied with power from the front of the chassis, make sure that power to the PEM is OFF, and the PEM circuit breaker is open, before attempting to remove the PEM. If both PEMs are supplied power from independent power sources from the front of the chassis, then either PEM can be removed without affecting service.
