  • Page 6 Using Micrel/Kendin software and your PC you can use the parallel port to reprogram the EEPROM on board, or use the SPI interface to access the KS8995MA’s full feature set. The board also features two MII connectors for the Switch MII interface. These are to facilitate connections from the switch to either an external CPU or an external PHY.

  • Page 7: Strap In Mode

    Strap in configuration mode is the quickest and easiest way to get started. In this mode, the KS8995MA acts as a stand alone 5 port switch. The user has to simply set the board’s configuration jumpers to the desired settings and apply power to the board. The user can also change jumper settings while power is applied to the board and press the convenient manual reset button for the new settings to take effect.

  • Page 8: Feature Setting Jumpers

    4.1.1 Feature Setting Jumpers The evaluation board provides jumpers to allow the user to easily set strap in configurations for the KS8995MA. Table 1 describes the jumpers and their function in the open or closed state. Table 1 Feature Setting Jumpers...

  • Page 9: Eeprom Mode

    The evaluation board has an EEPROM to allow the user to explore more extensive capabilities of the KS8995MA. The user can conveniently program the EEPROM on board using a parallel port from any computer with a WIN 95/98 DOS environment and the Micrel/Kendin provided software.

  • Page 10: Spi Mode

    Micrel/Kendin provides a simple Windows 98 DOS based program for the user to evaluate the KS8995MA’s full feature set. In addition to all the registers available via EEPROM programming, a host CPU connected to the KS8995MA’s SPI interface will be able to access all static MAC entries, the VLAN table,...

  • Page 11: 10/100 Ethernet Ports

    There are two MII ports on the KS8995MA. One port connects to the fifth MAC in the KS8995MA, and we refer to it as the Switch MII port. The second MII port connects to the fifth PHY in the KS8995MA. We refer to this as the PHY5 MII port. Both the Switch MII port and the PHY5 MII port configuration are set on the board by using the MII Enable bit (register 2, bit 3) in conjunction with JP6 and JP7 as shown in Table 6.
  • Page 12 Switch MII port will transmit and receive signals on J7, the Switch MII port’s male MII connector. This mode is usually used to connect the KS8995MA to a CPU. In MAC mode, the Switch MII port will transmit and receive signals on J8, which is a female MII connector.

  • Page 13: Software Description

    5.0 Software Description 5.1 EEPROM Programming Software in DOS Micrel/Kendin provides DOS based software so that you can use a computer with a Windows 98 DOS environment and a parallel port to program the KS8995MA evaluation board’s EEPROM without the added expense of an external EEPROM programmer. The program is an executable file that is included with your evaluation kit.
  • Page 14 9. Exit – Use this command to close the program. Please see the KS8995MA Datasheet for all register descriptions. Be sure to press the manual reset button after configuration so that the KS8995MA will reset and read the new configuration in the EEPROM. After reset, the KS8995MA is ready for normal operation.

    Please choose the appropriate folder for your Smartbits equipment, i.e. Smartbits 600, Smartbits 1000, Smartbits 2000. We recommend resetting the evaluation board for each new test to ensure that the KS8995MA comes up in default configuration. These scenario procedures assume that the user has prior experience with Smartbits equipment.

  • Page 18: Mib Counters

    KS8995MA Evaluation Board User’s Guide 6.1 MIB Counters There are 34 MIB counters per port on the KS8995MA. These counters are used to monitor port activity for network management. The following is an eMAmple of how to use Micrel/Kendin software and your computer’s parallel port to access the MIB counters.

    VLAN 1 will have in its membership ports 1, 2, 3 and 5. VLAN 2 will have in its membership ports 4 and 5. If an incoming packet is not tagged, the KS8995MA has a feature that will use the ingress port’s default VID for port forwarding. The KS8995MA also has an optional feature to discard packets whose VID port membership in the VLAN table does not include the ingress port.

Stop all transmission and clear all the Smartbits counters. Broadcast packets tagged with VLAN ID 1 from port 1, 2 or 3 to all ports. The broadcast packets should only be received on VLAN 1, ports 1, 2, 3 and 5.

    50,000 packets destined for port 3, and the 50,000 packets destined for port 4 were all mirrored on port 1. We can also take this a step further by having the KS8995MA mirror error packets to the “sniffer port” as well. This is useful for network management and debugging purposes.
  • Page 30 KS8995MA Evaluation Board User’s Guide 8.0 PCB Layout Guideline for ESD and EMI ESD and EMI (FCC) are basically the same problem for the system design. ESD is absorbing energy and EMI is emitting energy. If your PC board has low EMI, it is probably ESD proof as well.
