Stacked Configurations
Definition of stacking configuration:
• The P2-UMT Stacking Switch, a new switch device required for stacking configurations, 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
(3) 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.
• Base units can never act as stacking units.
