3.4.1 -- Installation on feet or on a wall mounting
For desktop installation, fit each unit with its four feet (kit ref: 9400UXI303), the feet clip onto the bottom of
the unit.
To install units on a wall mounting, use kit ref.: 9400UXI301 which can support a maximum of three units.
For this wall mounting, the feet of the units must not be fitted. Kit 9400UXI301 includes: two brackets, four fixings
for the brackets (M6 x 50 socket cap screws, onduflex washers and 4620 expansion bolts), and fixings by the
front handles for three units (washers 19621 and screws EX 10804).

3.4.2.2 -- Alcatel recommendations for IDU installation in 9U rack
The recommendations depend on IDU configurations (1+ 0, 1+1 basic or 1+1 mux protected )
-- 1+1 mux protected configuration : each group of 2 or 3 IDU shall be separated by 1U.
-- 1+0 or 1+1 basic configuration : each IDU shall be separated by 1U.
This configuration supposes that room temperature should not 45

C (and that the temperature at the
IDU level never exceeds 55

C) .
These recommendations allow good installation conditions (place for cable interconnections) and good
operation conditions (cooling of the IDU).
