What is a 8546 DSL Card?
A Digital Subscriber Line (DSL) 8546 card is a circuit card assembly (CCA) that
contains four Rate Adaptive Digital Subscriber Line (RADSL) ports, an Ethernet
interface to the Internet Service Provider (ISP), and a processor. The processor
controls the RADSL ports and forwards the packet traffic to and from the Ethernet
and DSL interfaces. When the 85

3. Slide the 8546 DSL card into the slot until the power and network connectors seat firmly in the mating connectors on the backplane. CAUTION: Do not force the 8546 DSL card into the slot. If it does not seat properly, remove the card and reinstall it. If it still does not seat properly, call service. The 8546 DSL card performs 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 SYSTEM OK indi

Connecting to a POTS Splitter or an MDF You can connect the HotWire DSLAM chassis containing the 8546 DSL card to a POTS splitter shelf, MDF, or other demarcation point. NOTE: If you are connecting the HotWire DSLAM to a CO POTS splitter, this procedure assumes that the CO POTS splitter shelf is already installed. For information on how to install the CO POTS splitter, refer to the HotWire POTS Splitter Central Office Installation Instructions, Document No. 5020-A2-GN10. Procedure To connect t

Connecting the DSL Cards to the Ethernet Hubs or Switches Procedure To connect the 8546 DSL cards to the Ethernet hubs or switches: 1. Plug the end of an 8-pin modular cable into the appropriate LAN/WAN SLOT port of the chassis. For example, if you want to connect to the LAN/WAN port of an 8546 DSL card, insert the 8-pin modular cable in LAN/WAN Slot #2. 2. Plug the other end of the cable into your Ethernet hub or switch connector. Refer to Pin Assignments on page 9 for pin assignments. — On a
