Unpacking Inspection
Check the received materials according to the packing list and ensure that all
the materials specied in the contract arrive at the site. After the inspection, sign
on the packing list with the customer and keep a backup of the packing list.
Preparing Installation Tools
• Cross screwdriver (M3–M6) • Flat-head screwdriver (M3–M6)
• Mount bar • Diagonal pliers
2 Installing the Subrack
Select a narrow brim of the cabinet
mounting bar as the baseline and
use M4 screws to install the guide
rail. The lower edge of the guide rail
must be ush with the baseline.
Install floating nuts in the first
and sixth square holes above the
baseline. (Select the first and third
square holes when installing the
U1911.)
Adjust the mounting ears (folded
by default) at the two sides of the
subrack based on the cabinet status
to prevent the situation that the
cabinet door cannot be closed after
cables are connected.
Put the subrack on the guide rails
and push it into the cabinet. Use
four M6 screws and the oating nuts
on the mounting bar to fasten the
device.
