Installing the IRFU in the rack
Allocate a free space of at least 0.4 RMS (18 mm or 0.7 in) between the bottom of the
IRFU bracket and the top of the CMU and, 1.3 RMS (58 mm or 2.3 in) between two IRFU
shelves.
Mounting brackets can be assembled for either ETSI or NEBS (ANSI) rack-mounting.
To minimize risk of injury, use two persons to place a fully assembled IRFU
(weighing approximately 12 kg) in the rack.
Install the shelf mounting lugs (2) using the machine screws provided. Leave these lugs in
place for holding the IRFU during installation. Starting with the two top screws, secure the
six mounting bracket screws to the rack (Figure 88).
