1. INTRODUCTION This guide is intended for the system or network administrator responsible for installing and monitoring a Transition Networks’ pocket switch. A working knowledge of local area network (LAN) operations, including familiarity with communications protocols used on interconnected LANs, is assumed.
The Evolving Ethernet Network Installing one Transition Networks’ pocket switch alone improves network performance. Installing additional Fast Ethernet equipment (and, optionally, installing additional Transition Networks’ pocket switches) can optimize network performance.
Network Flexibility The Transition Networks’ pocket switch can assist a network administrator in maintaining existing resources as the network evolves from shared legacy 10Mb/s Ethernet to switched .
4. OPERA TION The Transition Networks’ pocket switch requires no operator intervention beyond occasionally monitoring LED status indicators. POWER Steady green LED indicates connection to external AC power. NOTE: The port LED indicators provide separate data for each port.
Increasing Bandwidth by Segmenting 10BASE-T Collision Domain The Transition Networks’ pocket switch adapts to the fact that each Ethernet network device (station) is connected independently to the shared Ethernet signaling system, called the network medium.
Installing Network Cable (continued) Connecting Fiber Cable to TX/RX Connectors (100BASE-FX) Effective cable distances are determined by ambient RF noise and by signal loss in the cable. Since fiber has a low signal loss/meter and is invulnerable to RF noise, fiber can be used to extend distances.
Doubling Bandwidth by Installing Full-Duplex NOTE: The 10BASE-T specification requires two dedicated twisted copper wire pairs for data transmission and reception. This allows twisted pair copper cable to be used either in half-duplex or full-duplex mode.
Installing Network Cable (continued) Straight-Through/Crossover (10BASE - T /100BASE - T X ) The most popular wiring used today, unshielded twisted-pair copper cable, is used for 10BASE-T and for 100BASE-TX.
Increasing Bandwidth T en-fold by Installing 100BASE-TX (Fast Ethernet) Fast Ethernet, 100BASE-TX or 100BASE-FX on the Transition Networks’ pocket switch, moves signals at 100 Mb/s, ten times faster than legacy Ethernet. Legacy Ethernet and Fast Ethernet Since 100BASE-TX Fast Ethernet is an extension of the existing Ethernet IEEE 802.
The Transition Networks pocket switch can be installed to provide one 10BASE-T switched port and one 100BASE-TX switched port. Auto-Negotiation The 100BASE-TX standard includes automatic speed and duplex mode sensing as part of the Auto-Negotiation function.
Increasing Network Distance by Installing 100BASE-FX Fiber Fast Ethernet, 100BASE-FX, can be used for links to the Transition Networks’ pocket switch, particularly between buildings or where the 100 meter distance limitation of copper Fast Ethernet, 100BASE-TX, must be exceeded.
Setting DIP Switch NOTE: The Auto-Negotiation system is designed so that a twisted-pair link will not become operational until matching capabilities exist at each end.
2. SITE CONSIDERA TIONS The site for the Transition Networks’ pocket switch must provide: • AC power outlet for each Transition Networks’ pocket switch • Adequate ventilation • Standard envi.
