USER’S GUIDE

iv StackMaster™

Preface
This guide is intended for the system or network administrator responsible
for installing, configuring, using, and maintaining a Transition Networks
StackMaster™ unit or stacked set of units. A working knowledge of local
area network (LAN) operations, including familiarity with communications
protocols used on interconnected LANs, is assumed.

USER’S GUIDE

1. Introduction
The StackMaster™ Ethernet Repeater Stack is an expandable stack of
repeater hubs, connected to various media, that functions through an
inter-repeater bus as a single Ethernet repeater. The minimum
StackMaster™ configuration consists of a single unit: the 16-Port 10BaseT
hub, the 24-Port 10BaseT hub, the 6-Port 10BaseFL hub, or the 12-Port
10BaseFL hub.
The StackMaster™ configuration is expanded by adding up to five
additional StackMaster™ repeaters selected from among the 24-Port
10BaseT hub, the 6-Port 10BaseFL hub, and/or the 12-Port 10BaseFL hub.
Inter-repeater bus connectors, located on the back of the StackMaster™
hubs, are used for cascading the six hubs into a single repeater.
Optional SNMP Management of a StackMaster™ stack is provided either
by an external SNMP Management hub or by an optional SNMP
Management circuit board installed in the 16-Port 10BaseT hub, the
StackMaster™ 24-Port 10BaseT hub, the 6-Port 10BaseFL hub or the 12-
Port 10BaseFL hub. The SNMP Management hub and SNMP management
circuit boards provide SNMP formatted information to external network
management platforms.
Fully configured StackMaster™ stacks can be connected to each other in a
network. (Each stack must have separate SNMP network management.)
Standard Ethernet network conventions regarding cable distances and
segment numbers must be followed.
Selectable hubs used in the StackMaster™ stack include:
• 16-Port 10BaseT hub (with optional SNMP management board)
• 24-Port 10BaseT hub (with optional SNMP management board)
• 6-Port 10BaseFL hub (with optional SNMP management board)
• 12-Port 10BaseFL hub (with optional SNMP management board)
• SNMP Management hub

MANAGEABLE HUB

1.1 24-Port 10BaseT Repeater
The StackMaster™ 24-Port 10BaseT hub supports twenty-four RJ-45
10BaseT connections to either shielded or unshielded twisted pair.
Additionally, the StackMaster™ 24-Port 10BaseT hub supports installation
of an SNMP Management Board that allows the StackMaster™ 24-Port
10BaseT hub to manage the entire StackMaster™ Stack.
Connectors
Twenty-four (24) RJ-45 connectors are provided at the front of the 24-Port
10BaseT hub.
NOTE: A power connector, DB9 serial port connector, AUI port
connector, and Cascade (bus) connector are provided at the back of the
24-Port 10BaseT hub.
Indicators
When the StackMaster™ 24-Port 10BaseT hub is powered, the Power
indicator is illuminated. Combination Link/Partition LEDs above each of
the twenty-four RJ-45 connectors indicate link and partition status for each
of the twenty-four 10BaseT connections:
green LED: good link
red LED: partition
