 
Up to three P2-UMT832S units (Stacking Units) can be connected to 
one P2-UMT832M unit (Main Unit). 
 
Only one P2-UMT1664S unit (Stacking Unit) can be connected to 
one P2-1664M unit (Main Unit). 
 
A maximum of 128 channel ports (Main Unit + Stacking Units) is 
permitted. When a P2-UMT1664M unit acts as the Main Unit, only 
one P2-UMT1664S Stacking Unit can be in daisy chain with it. When 
a P2-UMT832M unit acts as the Main Unit, up to three P2-UMT832S 
Stacking Units can be in the daisy chain. 
 
You cannot mix unlike configurations of Main Units and Stacking 
Units. For example, you cannot use a P2-UMT832S Stacking Unit 
with a UMT1664 Main Unit and vice versa. 
 
These cannot be used as Stacking Units: P2-UMT1664M, 
P2-UMT832M, UMT1664, UMT832 (Paragon I with hardware version 
HW3). 
Important: If you power off a Stacking Unit when it remains 
CONNECTED to a Main Unit, the channel colors on the OSUI 
Selection Menu becomes abnormal . To avoid this problem, you 
must disconnect the Stacking Unit from the Main Unit before 
powering it off. See 
Note for Turning Off the Stacking Unit
 (on page 
31) for additional information.
