Installing the BCN and BCN RLC
You install the Backbone Concentrator Node (BCN) by
• Preparing for installation
• Setting up the BCN
• Powering up the BCN and observing the hardware platform as it initializes
• Cabling a console or modem to the hardware platform for access to the Bay
Networks Technician Interface
Note: This chapter describes how to install the Single AC Source (BCN) and
Dual AC Source (BCN RLC) versions. The BCN and the BCN RLC are both
referred to as BCN except where a differentiation is necessary. Only qualified
service personnel are permitted to connect the DC version of the BCN to a
power source. See Installing the DC Version of the BCN and BLN-2.
Danger: Due to high-energy hazards, only qualified service personnel are
permitted to repair a Backbone Concentrator Node. Chapter 5, “Hot-Swapping
Hardware Components,” describes user-serviceable procedures.
The BCN is not designed for use with an I.T. power system (a power
distribution system that has no direct connection to earth); the exposed
conductive parts of the BCN are grounded.
Warning: The BCN weighs approximately 214 lb (97.07 kg). Do not attempt
to lift it by yourself. Use a team of people or specialized lifting equipment.
