Procedure
Step 1 Align the rst detection point of the asset detection strip with the cabinet 42 U
position and attach it to the rack.
Step 2 Attach the main control box to the top of the cabinet front door interior (if there
is space at the top of the cabinet interior) or exterior (if there is no space at the
top of the cabinet interior).
Step 3 Connect cables between devices and secure the cables using fasteners.
● The securing positions of fasteners are for reference only. The actual mounting holes on the
cabinets prevail.
● The cable between the main control box and the UIM20A expansion module unit is delivered
with the smart U space manager.
● Attach the U space asset label to the detection point on the asset detection strip, facilitating
asset management.
● In a standard scenario, connect a smart U space manager to the COM6/AIDI_6 port on the
UIM20A expansion module.
● In a scenario where one UIM20A expansion module maps to four cabinets, connect smart U
space managers to the COM1/AIDI_1, COM3/AIDI_3, COM5/AIDI_5, and COM7/AIDI_7 ports
on the UIM20A expansion module. If the number of IT cabinets is not an integer multiple of
4, according to the cable connection rules, redundant COM ports exist on the UIM20A
expansion module.
