Preface This guide is intended for the system or network administrator responsible for installing, configuring, using, and maintaining a Transition Engineering StackMaster™TR. A working knowledge of local area network (LAN) oper- ations, including familiarity with communications protocols used on inter- connected LANs, is assumed.
.
1. Introduction The TRANSITION Networks 16-Port StackMaster™TR Active Retiming Managed Hubs are designed for building SNMP managed token ring LANs using twisted pair cable.
Connectors Ring In/Ring Out Connector An RJ-45 Ring In connector and an RJ-45 Ring Out connector are provided at the front of the 16-Port StackMaster™TR Active Retiming Managed Hub. Lobe Connectors Sixteen (16) RJ-45 lobe connectors are provided at the front of the 16-Port StackMaster™TR Active Retiming Managed Hub.
Connectors at Back A serial port connector for SNMP management and maintenance, two (2) Cascade (bus) connectors, and a power connector are provided at the back of the StackMaster™TR 16-Port. NOTE: The AUX connector is intended for future development.
Indicators Power LED When the StackMaster ™ TR 16-Port Unit is powered, the Power indicator is illuminated. Insert/Normal LEDs The Insert LED (above the Ring In port) is illuminated if the StackMaster ™ TR 16-Port RI port is connected to the RO port of a hub.
Port Status LEDs Port Status LEDs above each of the sixteen (16) RJ-45 lobe port connectors indicate insertion status for each of the sixteen connections: green LED: good insertion NOTE: Illuminated L.
Switches Active/Passive Switches A(ctive) and P(assive) switches are provided for the Ring In port and for the Ring Out port for connection to active ( “ A ” ) or to passive ( “ P ” ) hubs. ZDL Switch The ZDL Switch allows selection of automatic speed detection.
4Mbps/16Mbps Switch The 4Mbps/16Mbps Speed Selection Switch allows selection of data rate (4Mbps or 16Mbps). NOTE: The StackMaster ™ TR 16-Port Hub must be reset when the 4Mbps/16Mbps switch position is changed. NOTE: Network speed affects maximum twisted pair cable distances.
.
2. Site Planning Site planning for the StackMasterTR Stack requires consideration both of site conditions and of token ring standards. 2.1 Site Considerations The site for the StackMasterTR Token Ring.
2.2 Network Parameters Data Sheets NOTE: SNMP network management is optional. The network parameter data sheets are intended to be a permanent record of site-specific network parameter values that will be required for configuring SNMP network management.
SNMP Network Parameters Data Sheet CATEGORY StackMasterTR DEFAULT SITE ENTRY ( commwrite ) Security permission PRIVATE Format: PRIVATE/PUBLIC Authorization ( auth ) Security identifier DISABLE Format: DISABLE/ENABLE System name ( sysname ) Site-specific identifie -- usually.
Serial Port Parameters Data Sheet CATEGORY StackMasterTR DEFAULT SITE ENTRY Transmission rate ( bps ) Transmission speed, in bits 9600 per second Format: 9600/ Name ( stop bitse ) Serial protocol definition entry. 1 Format: NONE/1 ( data bits ) Serial protocol definition entry.
