2.1 General
This chapter explains in detail the requirements and procedures for the
installation of the FRM301 Rack Mount Series Fiber Converter Concentrator.
2.2 Site Preparation
Install the FRM301 within reach of an easily accessible grounded AC outlet. The
outlet should be capable of furnishing 90 to 250 VAC. Refer to 2.4 Electrical
Installation. Allow at least 10cm (4 inch) clearance at the front of the FRM301 for the
Ethernet cables.
2.3 Mechanical Assembly
The FRM301 is designed for rack mount installation and will require 3U space in
a standard EIA 19" or 23" rack. For the FRM301, there are three fan units in the rear
side of the chassis and an independent fan assembly on each power module. Without
operation fans, excessive temperatures within the unit might cause it to electrically
shutdown. The FRM301 chassis is delivered completely assembled, however
converter cards may or may not be installed in the chassis upon delivery. The rack
mount adapters may be placed along the front or centrally located on the chassis.
Optional brackets also allow installation into a 23" rack and in this configuration,
central mounting is recommended.
