    Architecture. This module can operate in two modes: either as a 26-port Ethernet traditional switch (using 802.1d standards) with a high speed backbone connection, or as a SecureFast switch (SFS) with 26 Ethernet connections. Each port can be configured to operate in the full duplex mode. This configuration allows each 100BASE-T port to provide a full 200 Mbps.

  • Page 10: Features

    Spanning Tree, RMON, and MIB support, within a scalable RISC-Based architecture. Fast Packet Switching The 9H423-26 module incorporates a hardware-based switch design referred to as the SmartSwitch ASIC, a collection of custom ASICs designed specifically for high-speed switching. Because all frame translation, address lookups, and forwarding decisions are performed in hardware, these modules can obtain a throughput performance of greater than 750K pps.
  • Page 11 Auto-negotiation The auto-negotiation feature (available only with the 100BASE-T RJ21 ports) allows the module to automatically use the fastest rate supported by the device at the other end (either 10 Mbps or 100 Mbps at either half or full duplex). To negotiate duplex, both the 9H423-26 and the attached device must be configured for auto-negotiation.
  • Page 12 Introduction The 9H423-26 module attaches to INB-B of the SmartSwitch 9000 Backplane. The INB backplane is designed to transport fixed-length data blocks between modules in the SmartSwitch 9000 using an INB Time Division Multiplexing (ITDM) design. The SmartSwitch 9000 INB bus delivers 2.5 Gbps of true data bandwidth with all control and management communication being serviced on the 8-bit out-of-band bus.

    The DIP switch on the 9H423-26 module (Figure 2-1 ), is an eight-switch DIP located near the left, bottom corner of the module. Each switch is set according to the functions described in Table 2-1. If switch settings are changed, the processor on the module must be reset, using the reset switch or repowering the module, for changes to take effect.

    Chapter 3 Operation The 9H423-26 module is a twenty-seven port device. Two front panel RJ21 connectors support twenty-four 100BASE-T ports, along with two SC fiber connectors that support two 100BASE-FL ports. Each of these twenty-six ports is a separate collision domain, while the 27th port connects to INB-B. As shown in Figure 3-1, Fast Ethernet Network Interface Blocks (FENIBs) convert data packets received from any of the 100BASE ports into a canonical frame format before forwarding to the SmartSwitch ASIC, while the Internal Network...

    SMB-10 Bus The SMB-10 is a 10 Mbps management bus located within the SmartSwitch 9000. This bus is used for inter-chassis communication of modules as well as serving as a side-band management channel into the SmartSwitch 9000. The SMB-10 is externalized from the chassis via an optional Ethernet Port Interface Module (EPIM) located on the front of the Environmental Module.

  • Page 28: Itdm Arbitration Levels

    Operation Arbitration for the backplane is accomplished in the INB Time Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensures that no one can get the backplane for more than one time slice at a time. The ITDM RAM contains 256 4-bit locations. This RAM is used to hold slot numbers of modules participating in INB backplane arbitration.

    The colors in bold designate the primary color of the wire. For example, pin 26 connects to a NOTE wire that is primarily white with blue stripes and pin 1’s wire is underlying blue with white stripes. However, because Category 5 has more “twists” than Category 3, vendors might manufacture the twisted pairs with the primary colors only.

  • Page 49: Why Are Cat 5 Connectors Necessary For 100Base-Tx

    Why are CAT 5 Connectors Necessary for 100BASE-TX? Similar to the UTP cable itself, the connector hardware plays an important role in the overall performance of the assembly. If an electrical signal travels through a Category 5 cable with little attenuation and then meets an inferior connector, the signal will presently be degraded due to the connector.

    Fiber Optic Cabling As mentioned previously, the 9H423-26 utilizes 1300 nm, 62.5/125 m fiber. Because it will be primarily used in a ‘backbone cabling’ configuration, the following optical fiber specifications will be stated per this case. (If implementing Horizontal type fiber connections, see TIA/EIA 568A, section 12.2.) The fiber will be multimode graded-index, 62.5/125 m core/cladding diameter.
