    This manual provides installation and reference information for the network adapters. The network adapters connect your PC to an IEEE 802.5, Token-Ring network using shielded twisted pair cable of types 1, 2, 6, 8, and 9, or unshielded voice-grade IBM type 3 twisted pair cable.

  • Page 10: The Adapter Features

    INTRODUCTION THE ADAPTER FEATURES The following sections outline the features of the adapters. 1.2.1 Connectivity The Cabletron Systems adapters connect your computer to an IEEE 802.5 Token-Ring network. The various adapter models incorporate both an unshielded (RJ-45 UTP) twisted pair port, and a DB-9 shielded twisted pair port.

    INTRODUCTION 1.2.4 LANVIEW LEDs Cabletron Systems’ adapters incorporate Cabletron Systems’ LANVIEW Status Monitoring and Diagnostic System. The LANVIEW LEDs help you diagnose problems, such as failure to establish a twisted pair link between the adapter and a device at the far end of the link. Individual LEDs advise you when the adapter is sending and receiving data packets, when wire faults occur in the lobe link, and the operating speed of histogen-Ring.

    Clock Source. The I/O base address is set through a pair of dip switches. If your T2015 adapter is being installed in a computer that requires a synchronous clock source for its adapter boards, you will also need to change the clock source jumper.

  • Page 15: Setting The I/O Base Address

    Network Software Installation Guide. 2.3.1 Setting the I/O Base Address Before the T2015 adapter can be used, the I/O base address must be set using a pair of two-position dip switches accessible through the card’s bracket. The switches are located just below the ports on the bracket (see Figure 2-2).
