Multiple Base Configuration
Definition of Multiple Base configuration:
• Two or more UMT Matrix Switches serve as base units.
• The base unit must always be the latest released version, both in hardware and firmware.
• A maximum of three (3) tiers, including the base unit, is permitted.
• Upper-tier devices connect to two or more base UMTs.
• Devices that are not UMT Matrix Switches but have two or more channel ports, such as Raritan
MasterConsole or CompuSwitch, are treated as tier devices. These devices cannot act as base devices
in a Paragon system and can be connected only to a base unit or a second tier UMT(s)
Initialization of a multiple base configuration with tiered devices
− After all devices have been connected, power ON the devices from upper tier to lower tier.
− After initialization, each tiered device has an updated database.
Guidelines for changing connections of tiered devices:
Example A: Relocating a 3
rd tier device with multiple 2 nd tier connections (refer to red colored dotted line
in diagram):
1. Disconnect some or all of the user ports on an upper-tier unit (UMT-3A) that connect to the channel
ports of a lower-tier unit (UMT-2A) and re-connect the user ports to the channel ports of lower-tier
unit (UMT-2B).
2. Change the cable connections of the upper-tier unit (UMT-3A).
3. Recycle the power of tiered devices. This is recommended to build a clean database for the UMT
Matrix Switches. Sequence of recycling power is from the highest tier (tier 3) to the base unit. In our
example: UMT-3A
→ UMT-2A → UMT-2B → UMT-Base 1 → UMT-Base 2.
Example B: Relocating a 2 nd tier device with multiple base tier connections (refer to blue colored dashed
line in diagram):
1. Disconnect some or all of the user ports on a tiered unit (UMT-2C) that connect to the channel ports of
a base unit (UMT-Base 1) and re-connect those user ports to another base unit (UMT-Base 2).
2. Change the cable connections of the tiered unit (UMT-2C).
3. Recycle the power of tiered devices. This is recommended to build a clean database for the UMT
Matrix Switches. Sequence of recycling power is from the highest tier (tier 3) to the base unit. In our
example: UMT-2C
→ UMT-Base 1 → UMT-Base 2.
4. The operation is the same for devices that are not UMT Matrix Switches.
