CU Link connection:
Up to 3 50CUs can be cascaded (cascade 50CUs using the CU
LINK A/B terminals as shown below). Set one of the 50CUs as
the primary unit.
Since up to 100 50DU/INTs can be connected to each 50CU, if
you use 3 CUs, up to 300 50DU/INTs can be connected in total.
Follow the procedure below to cascade CUs.
① Connect the CU LINK A terminal on the 1st extension 50CU
to the CU LINK B terminal on the primary 50CU.
② W hen cascading 2 extension 50CUs, connect the CU LINK A
terminal on the 2nd extension 50CU to the CU LINK B terminal
on the 1st extension 50CU.

• You can either daisy-chain (
28) 50DU/INTs to each 50CU.
• W hen using only one 50CU without a CU Link
connection, be sure to set [CU Link Settings] to
[Primary].
If [CU Link Setting] is set to [Extension Pass Through]
or [Extension Last Unit], we cannot assure operations.
• Up to 6 INTs can be connected to the primary 50CU.
They cannot be connected to extension 50CUs.
Attach the bottom cover to the 50DU/INT.
After connecting the Ethernet cables to the 50DUs/INTs, attach
the bottom cover to each 50DU/INT.
• The Ethernet cable is fixed securely between the 50DU/INT
and the bottom cover. This helps reduce the weight of the
50DU/INT which bears on the Ethernet cables.
• To lead the cable out to the rear side, use the through hole ① .
To lead the cable out to the bottom side, use the through holes

Attach the optional bottom weight to the 50DU/
INTs.
• W hen using 50DU/INTs that are not secured to desktops
or tabletops, it is recommended to use the optional
bottom weight (330g) for secure placement.
