13 About the Hotwire 8810 DSLAM 1 What is the Hotwire 8810 DSLAM? The Hotwire 8810 Digital Subscriber Line Access Multiplexer (DSLAM), which can be installed at the Network Service Provider (NSP), provides high-speed Internet or intranet access. Through the use of Digital Subscriber Line (DSL) technology, the DSLAM provides simultaneous high-speed data access (digital) and Plain Old Telephone Service (POTS) service (analog) over the same twisted-pair telephone line. Support of this simultaneous access requires the installation of POTS splitters at both ends of the line (i.e., at the central office (CO) and at the customer premises (CP)). When used in combination with a Hotwire 8100/8200 Interworking Packet Concentrator (IPC), the Hotwire 8810 DSLAM provides high-speed IP service concentration over a wide array of LAN architectures as well as ATM interfaces to Wide Area Networks (WANs). The 8810 DSLAM is designed to provide a higher port density carrier, for use with new and future high-density port cards. Existing 4-port cards installed in the 8810 DSLAM still access their network Tip and Ring connections using the three connectors located on the front of the unit, as on the 8800 DSLAM. To support the high-density port cards with greater than four ports per card, the 8810 DSLAM is equipped with 18 additional 50-pin connectors, located on the rear of the chassis. These connectors are wired to their respective port slots; that is, connector 1 is wired to port slot 1, connector 2 is wired to port slot 2 and so on, up to port slot 18. Each of these 50-pin connectors can support up to 25 Tip and Ring pairs per slot A2-GN20-00 October

16 About the Hotwire 8810 DSLAM Hotwire 8810 DSLAM Features The Hotwire 8810 DSLAM system has the following features: Power Redundancy The chassis provides a power input terminal block, which is capable of accepting two independent 48 Vdc power inputs. Two power sources can be connected to the chassis to provide power redundancy. If one power source fails, the other source provides all of the power needed by the system. This is done automatically without system disruption. The chassis distributes 48 Vdc power from the CO power source to individual cards via the interface module and the backplane. A Convenient Front-Facing Interface Panel The interface panel on the chassis allows all interface cables to be connected and maintained in the front of the chassis for easy accessibility. Major/Minor Alarm Contacts for CO Alarm Requirements The interface panel provides two sets of dry contacts on a 6-pin jack interface for connection to a CO alarm system. LED Monitors for Power and Fan Status and Major and Minor Alarms LEDs on the front panel of the Hotwire 8810 chassis are indicators of the status of chassis functioning. For more information on the meaning of LED indications, see Appendix A, LEDs. Hot Swappable Cards The MCC and DSL cards can be installed and removed from the chassis without service disruption to other cards. Network Equipment Building Standards (NEBS) The 8810 DSLAM meets Network Equipment Building Standards (NEBS) Level 2 Criteria. In addition, it meets NEBS Level 3 Earthquake (Zone 4 Level). Refer to NEBS Heat Release Limits to determine the number of chassis that can be mounted in a rack.

28 Installing and Connecting the Hardware Installing the Chassis with a 3- or 5-Inch Setback The chassis may be installed with a 3- or 5-inch setback in either the 19- or 23-inch rack. Procedure 1. Remove the screws that attach the mounting brackets to the sides of the chassis. NOTE: Only two screws are used to attach the bracket on the left side for flush mounting. A third screw, necessary for setback mounting, is already installed behind the left bracket near the top of the chassis. Remove this screw and save it. Third Screw for Setback Installation Position the brackets set back 3 or 5 inches from flush mount. (Refer to procedures for reversing brackets if installing in a 23-inch rack.) 3. Use three screws on each side to attach the brackets in the setback position. 4. Follow the procedures for installing the chassis in a 19- or 23-inch rack October A2-GN20-00

29 Installing and Connecting the Hardware Installation into a Rack without Threaded Screw Holes Procedure To install the chassis in a rack that does not have threaded screw holes: NOTE: Install the chassis starting at the bottom of the rack. 1. Determine the preferred placement of the chassis in the rack. The chassis is inches high and the keyhole slots are located 3.25 inches from the bottom of the chassis (for a 19-inch rack). 2. Slip a speed nut onto each rail hole selected and align the hole of the speed nut with the hole in the rail. Front Rail Speed Nut Screw Keyhole Front of 19-inch Rack Line up the chassis mounting bracket with the speed nut and start to rotate the speed-nut screw into the chassis mounting bracket and the speed nut. Start all four screws, then tighten all four until each screw head is flush with the chassis and is securely mounted in the rack A2-GN20-00 October

30 Installing and Connecting the Hardware High-Density Back-to-Back Installations For high-density applications, the chassis can be mounted back-to-back. This type of mounting configuration requires another set of vertical rails positioned at least 24 inches to the rear when mounting the chassis in the back of the rack. Also keep in mind that you must: Reposition the top cover air flow vents for each chassis before installing the chassis into the rack. To do this, disassemble and reverse the rear baffle plate on the top and reposition it with the air vents facing upward. Air Flow Vents Leave at least 1.75 inches between a chassis and the one above it (3.5 inches preferred).

32 Installing and Connecting the Hardware Supplying Power The Hotwire 8810 DSLAM chassis operates from a 48 Vdc power source. It allows for two power input feeds, which provide input power redundancy. If one power input (e.g., Power A) fails, the system continues to be powered by the other power input (e.g., Power B). The Power A and Power B terminals, which are located on the Interface Panel, are accessible from the front of chassis. These connections supply power to the cards via the backplane and interface module. Procedure To supply power to the chassis: Make sure that the power source wires are not powered (i.e., the circuit breakers are open or fuses are removed). Verify that the tips of the power source wires (10 AWG through 16 AWG solid or stranded wire) are stripped of insulation. If they are not already stripped of insulation, strip the tip of each wire (about 1/3-inch in length) before plugging each wire into its appropriate terminal on the 48V input terminal block. 1. Insert the following wires into the appropriate terminal and fasten each wire by securely tightening the screw above it: Insert the... Into the...

CAUTION: Do not force the MCC card into the slot. If it does not seat properly, remove the card and reinstall it. If it still does not seat properly, call for service. 4. The MCC card will now perform a power-up self-test. All of the LEDs turn ON and OFF briefly. When the self-test is completed successfully, the SYSTEM OK LED will turn ON. Make sure the OK SYSTEM indicator on the MCC faceplate is ON (winking green). 5. Secure the MCC card by fastening the top and bottom screws on the faceplate. This is required to maintain proper gasket pressure on the faceplate as well as proper air flow. NOTE: The MCC card may be replaced without disruption to user data (i.e., you can remove and reinstall the MCC card without powering down the chassis and disrupting service to the other cards). To remove the MCC card from the chassis, unfasten the screws on the top and bottom of the faceplate. Then, simply push the ejector handles outward and slide the card out. When swapping the old MCC card with a new MCC card, it is important to note that the Hotwire 8810 DSLAM retains the Media Access Control (MAC) address, also referred to as the physical address.

38 Installing and Connecting the Hardware Verifying the Installation To verify the hardware installation, observe the front panel indicators. In normal operation: The POWER A LED and/or the POWER B LED are in the ON state (green). If you are using dual power sources, both Power LEDs must be ON. If you are using a single power source, the appropriate Power LED (either Power A or Power B) must be ON. The FAN ALARM LED must be OFF. Also check the SYSTEM LEDs on the MCC and DSL cards if you have not done so already. The OK SYSTEM indicators on the cards must be in the ON state (winking green). If these status indicators fail to appear as described, see Chapter 4, Troubleshooting, for troubleshooting procedures. Also refer to Appendix A, LEDs, for a complete list of these indicators and their descriptions. Installing the Front Network Tip and Ring Connections Before installing the network connectors, the correct slot must be identified. On the back of the 8810 chassis, the connectors are labeled 1 18, from right to left. This corresponds with the 18 circuit card slots. The cable for the first slot is installed in the connector identified as 1 and so on. NOTE: Certain cards use the 50-pin connectors on the front access module for the network Tip and Ring connections. Higher density cards use the 50-pin connectors on the back of the carrier. These instructions provide generic examples of telephone line cabling. Refer to the specific installation instructions provided with the card for details. Installing the Rear Network Tip and Ring Connections Locking Pivot Brackets The network Tip and Ring connections for cards with more than four ports must be equipped with an end-fed plug connector.
