Stacked Configurations
Definition of stacking configuration:
• The P2-UMT Stacking Switch expands the number of available channel ports in a single
switch. It does not add user ports.
− UMT Stacking Switch P2-UMT1664S has four 68-pin expansion ports. Two are input
ports and two are output ports. The P2-UMT832S has only one 68-pin expansion input
port and one output port.
• The P2-UMT1664M has two 68-pin expansion ports, and P2-UMT832M has one 68-pin
expansion port. These represent input ports.
• One or more UMT Stacking switches connect to a P2-UMT Matrix Switch through stacking
cables in a daisy chain connection – that is, the expansion port of a P2-UMT832M connects
to the expansion output port of a P2-UMT832S, and the expansion input port of this P2-
UMT832S connects to the expansion output of another P2-UMT832S to form a daisy chain.
• For purposes here, this P2-UMT Matrix Switch is called the Master Device, and the UMT
Stacking Switch is called the Stacking Device.
• The Master Device can be a base unit or a tiered unit.
− The stacking device that connects to a master device becomes an automatic extension of
the master unit.
System Constraints:
• The base unit should be a P2-UMT1664M / P2-UMT832M Matrix Switch
• The base unit must always be the latest release of P2-UMT Matrix Switch (hardware and
firmware) in a closed configuration system.
• A Paragon I HW3 (with P2 firmware) can accommodate only one stacking switch.
• Up to three P2-UMT832S stacking units can be connected to each P2-UMT832M matrix unit.
• Only one P2-UMT1664S stacking units can be connected to each P2-1664M matrix unit.
• A maximum of 128 channel ports (Master Device + Stacking Devices) is permitted. When a
P2-UMT1664M Matrix Switch acts as the Master Device, only one P2-UMT1664S Stacking
Switch can be in daisy chain with it. When a P2-UMT832M Matrix Switch acts as the Master
Device, up to three P2-UMT832S Stacking Switches can be in the daisy chain.
• A P2-UMT1664M can have only P2-UMT1664S Stacking Switches daisy chained to it. A
P2-UMT832M can have only P2-UMT832S Stacking Switches daisy chained to it. You
cannot mix unlike configurations of Master Devices and Stacking Switches. For example,
you cannot use a P2-UMT832S Stacking Switch with a UMT1664 Master Device and vice-
versa.
• P2-UMT1664M / P2-UMT832M Matrix Switch and UMT1664/UMT832 hardware III Matrix
Switch cannot act as Stacking Devices.
Important: Do not power OFF an S Unit (Stacking Unit) when it is still connected to an
M Unit (Main Unit). Keep the S Unit powered ON until it is disconnected from the M Unit.
