System Installation
3.1 General
The RADring hub is a compact 3U high 19" enclosure accepting up to 20
RADring modules. The hub incorporates a common logic module (CML)
which can optionally include network management support (CML/NM) and
one or two power supplies. When two power supplies are installed
additional reliability is achieved, with each power supply capable of fully
supporting a fully loaded hub.
The RADring can be installed as a single centralized access center, capable
of providing up to 80 Token Ring or Ethernet connections, or as part of a
larger network, through connection of additional hubs.
The RADring hub is delivered completely assembled and is designed for
installation in a 19" rack on a bench or shelf. Care should be taken that the
air flow around the unit is unrestricted and that the cooling fan located at the
rear of the enclosure is not obstructed.
Equipment emitting a large amount of heat, which can raise the ambient
temperature, should not be installed in the vicinity of the enclosure.
This chapter describes the mechanical and electrical installation procedures
for the RADring hub. If any problems are encountered, refer to the
paragraph on fault isolation and troubleshooting (see Section 4.3). Once the
unit has been installed, turn to Chapter 4 for operating instructions.
